    How same-sex couples manage the process of seeking help for their relationships is an under-researched area. Twelve semi-structured interviews were conducted with 16 people who had engaged in same-sex couple counselling, and were analysed using discourse analysis. The ways in which the couples positioned themselves as part of a "minority…

    In this paper we introduce a novel gossiping primitive to support privacy preserving data analytics (PPDA). In contrast to existing computational PPDA primitives such as secure multiparty computation and data randomization based approaches, the proposed primitive `anonymous gossiping' is a communication primitive for privacy preserving personalized information aggregation complementing such traditional computational analytics. We realize this novel primitive by composing existing gossiping mechanisms for peer sampling & information aggregation and onion routing technique for establishing anonymous communication. This is more an `ideas' paper, rather than providing concrete and quantified results.

    In 'New Threats to Academic Freedom' Francesca Minerva argues that anonymity for the authors of controversial articles is a prerequisite for academic freedom in the Internet age. This argument draws its intellectual and emotional power from the author's account of the reaction to the on-line publication of ' After-birth abortion: why should the baby live?'--an article that provoked cascades of hostile postings and e-mails. Reflecting on these events, Minerva proposes that publishers should offer the authors of controversial articles the option of publishing their articles anonymously. This response reviews the history of anonymous publication and concludes that its reintroduction in the Internet era would recreate problems similar to those that led print journals to abandon the practice: corruption of scholarly discourse by invective and hate speech, masked conflicts of interest, and a diminution of editorial accountability. It also contends that Minerva misreads the intent of the hostile e-mails provoked by 'After-birth abortion,' and that ethicists who publish controversial articles should take responsibility by dialoguing with their critics--even those whose critiques are emotionally charged and hostile.

  7. Counseling parents before prenatal diagnosis: do we need to say more about the sex chromosome aneuploidies?

    Science.gov (United States)

    Lalatta, Faustina; Tint, G Stephen

    2013-11-01

    Sex chromosome trisomies (SCT), an extra X chromosome in females (triple X, XXX), males with an extra X chromosome (Klinefelter syndrome, XXY) or an extra Y chromosome (XYY) occur because of errors during meiosis and are relatively frequent in humans. Their identification has never been the goal of prenatal diagnosis (PD) but they almost never escape detection by any of the methods commonly in use. Despite recommendations and guide-lines which emphasize the importance of structured counseling before and after PD, most women remain unaware that testing for serious genetic abnormalities is more likely to uncover these trisomies. With the increasing use of PD more and more prospective parents receive a diagnosis of sex chromosome trisomies and are faced with the dilemma of whether to terminate the pregnancy or to carry it to term. Despite the dramatic and emotionally devastating consequences of having to make such a decision, they have little opportunity to consider in advance the possible outcomes of such a pregnancy and, rather than relying on their own feelings and judgements, are forced to depend on the advice of counseling professionals who may or may not themselves be fully aware of what having an extra sex chromosome can mean to the development of a child. We address here the principles of reproductive autonomy together with an analysis of the major issues that ought to be discussed with the parents before a PD is carried out in order to minimize detrimental effects caused by this unexpected finding.

    2010-01-01

    In recent years the amount of digital data in the world has risen immensely. But, the more information exists, the greater is the possibility of its unwanted disclosure. Thus, the data privacy protection has become a pressing problem of the present time. The task of individual privacy-preserving is being thoroughly studied nowadays. At the same time, the problem of statistical disclosure control for collective (or group) data is still open. In this paper we propose an effective and relatively simple (wavelet-based) way to provide group anonymity in collective data. We also provide a real-life example to illustrate the method.

    Large genome size, including immense repetitive and non-coding fractions, still present challenges for capacity, bioinformatics and thus affordability of whole genome sequencing in most amphibians. Here, we test the performance of a single transcriptome to understand whether it can provide a cost-efficient resource for species with large unknown genomes. Using RNA from six different tissues from a single Palearctic green toad (Bufo viridis) specimen and Hiseq2000, we obtained 22,5 Mio reads and publish >100,000 unigene sequences. To evaluate efficacy and quality, we first use this data to identify green toad specific candidate genes, known from other vertebrates for their role in sex determination and differentiation. Of a list of 37 genes, the transcriptome yielded 32 (87%), many of which providing the first such data for this non-model anuran species. However, for many of these genes, only fragments could be retrieved. In order to allow also applications to population genetics, we further used the transcriptome for the targeted development of 21 non-anonymous microsatellites and tested them in genetic families and backcrosses. Eleven markers were specifically developed to be located on the B. viridis sex chromosomes; for eight markers we can indeed demonstrate sex-specific transmission in genetic families. Depending on phylogenetic distance, several markers, which are sex-linked in green toads, show high cross-amplification success across the anuran phylogeny, involving nine systematic anuran families. Our data support the view that single transcriptome sequencing (based on multiple tissues) provides a reliable genomic resource and cost-efficient method for non-model amphibian species with large genome size and, despite limitations, should be considered as long as genome sequencing remains unaffordable for most species.

    In this paper we consider the problem of anonymizing datasets in which each individual is associated with a set of items that constitute private information about the individual. Illustrative datasets include market-basket datasets and search engine query logs. We formalize the notion of k-anonymity for set-valued data as a variant of the k-anonymity model for traditional relational datasets. We define an optimization problem that arises from this definition of anonymity and provide a constant factor approximation algorithm for the same. We evaluate our algorithms on the America Online query log dataset.

  11. An Anonymity Revocation Technology for Anonymous Communication

    Antoniou, Giannakis; Batten, Lynn; Parampalli, Udaya

    A number of privacy-enhancing technologies (PETs) have been proposed in the last three decades offering unconditional communication anonymity to their users. Unconditional anonymity can, however, be a security threat because it allows users to employ a PET in order to act maliciously while hiding their identity. In the last few years, several technologies which revoke the identity of users who use PETs have been proposed. These are known as anonymity revocation technologies (ARTs). However, the construction of ARTs has been developed in an ad hoc manner without a theoretical basis outlining the goals and underlying principles. In this chapter we present a set of fundamental principles and requirements for construction of an ART, identifying the necessary features. We then propose an abstract scheme for construction of an ART based on these features.

    The history of science is replete with important works that were originally published without the author's legal name being revealed. Most modern scientists will have worked anonymously in their capacity as peer reviewers. But why is anonymity so popular? And is it a valid approach? I argue that pseudonymity and anonymity, although not appropriate for all forms of scientific communication, have a vital role to play in academic discourse. They can facilitate the free expression of interpretations and ideas, and can help to ensure that suggestions and criticisms are evaluated dispassionately, regardless of their source. PMID:23570959

    2014-02-01

    The willingness of male-male dyads to use couples voluntary HIV counseling and testing (CVCT) has not been previously investigated globally among men who have sex with men (MSM). Using online advertisements, data were collected from 3245 MSM in seven countries who were ≥ 18 years of age and had ≥1 male sex partner in the previous 12 months. The analysis examined associations between individual characteristics and willingness to utilize CVCT. The willingness to utilize CVCT was compellingly high, ranging from 79% in Australia and UK to 90% in Brazil. Older MSM and those who reported not knowing their sero-status reported lower odds of willingness to use CVCT. The relationship between being in a relationship and willingness to use CVCT varied across countries, perhaps reflecting varied local understandings of the nature and content of CVCT. Further work is required to examine willingness to use CVCT among a more heterogeneous population of MSM, and to examine how CVCT services are locally perceived in order to provide information vital for the development of locally appropriate messages to promote CVCT for MSM.

    Full Text Available The evolution and increasing popularity of mobile handheld devices has led to the development of payment applications. The global acceptance of mobile payments is hindered by security and privacy concerns. One of the main problems evoked is the anonymity related with banking transactions. In this paper I propose a new secured architecture for mobile banking. Anonymity and privacy protection are the measures to be enhanced in order to satisfy people’s current needs. The banking platform must provide the highest level of security for messages exchanged between bank and the customer.

    Today's advanced scenario where each information is available in one click, data security is the main aspect. Individual information which sometimes needs to be hiding is easily available using some tricks. Medical information, income details are needed to be kept away from adversaries and so, are stored in private tables. Some publicly released information contains zip code, sex, birth date. When this released information is linked with the private table, adversary can detect the whole confidential information of individuals or respondents, i.e. name, medical status. So to protect respondents identity, a new concept k-anonymity is used which means each released record has at least (k-1) other records in the release whose values are distinct over those fields that appear in the external data. K-anonymity can be achieved easily in case of single sensitive attributes i.e. name, salary, medical status, but it is quiet difficult when multiple sensitive attributes are present. Generalization and Suppression are used to achieve k-anonymity. This paper provides a formal introduction of k-anonymity and some techniques used with it l-diversity, t-closeness. This paper covers k-anonymity model and the comparative study of these concepts along with a new proposed concept for multiple sensitive attributes.

    Background Even in the presence of promising biomedical treatment as prevention, HIV incidence among men who have sex with men has not always decreased. Counseling interventions, therefore, continue to play an important role in reducing HIV sexual transmission behaviors among gay and bisexual men and other men who have sex with men. The present study evaluated effects of a small-group counseling intervention on psychosocial outcomes and HIV sexual risk behavior. Method HIV-positive (HIV+) peer counselors administered seven 2-hour counseling sessions to groups of 5 to 8 HIV+ gay and bisexual men. The intervention employed information provision, motivational interviewing, and behavioral skills building to reduce sexual transmission risk behaviors. Results There was a significant reduction in condomless anal sex (CAS) with HIV-negative and unknown HIV-status partners, from 50.0% at baseline to 28.9% of the sample at 3-month follow-up. Findings were robust even when controlling for whether the participant had an undetectable viral load at baseline. Significant reductions were also found in the two secondary psychosocial outcomes, loneliness and sexual compulsivity. Conclusions The findings provide preliminary evidence that this intervention may offer an efficient way of concurrently reducing CAS and mental health problems, such as sexual compulsivity and loneliness, for HIV+ gay and bisexual men.

    Full Text Available The paper presents an innovative solution in the field of RFID (Radio-Frequency IDentification smartcard authentication. Currently the smartcards are used for many purposes - e.g. employee identification, library cards, student cards or even identity credentials. Personal identity is revealed to untrustworthy entities every time we use these cards. Such information could later be used without our knowledge and for harmful reasons like shopping pattern scanning or even movement tracking. We present a communication scheme for keeping one’s identity private in this paper. Although our system provides anonymity, it does not allow users to abuse this feature. The system is based on strong cryptographic primitives that provide features never available before. Besides theoretical design of the anonymous authentication scheme and its analysis we also provide implementation results.

    HIV prevalence among Chinese men who have sex with men has rapidly increased in recent years. In this randomized, controlled study, we tested the feasibility and efficacy of motivational interviewing to reduce high-risk sexual behaviors among this population in Changsha, China. Eighty men who have sex with men were randomly assigned to either the intervention group, in which participants received a three-session motivational interviewing intervention over 4 weeks, or the control group, in which participants received usual counseling from peer educators. High-risk behavior indicators and HIV knowledge level were evaluated at baseline and 3 months after the intervention. Motivational interviewing significantly improved consistent anal condom use. However, there was no significant change in consistent condom use for oral sex or in the number of sexual partners over time. HIV knowledge scores improved equally in both groups. This study demonstrated that an intervention using motivational interviewing is feasible and results in increased condom use during anal sex for Chinese men who have sex with men. However, further work must be done to increase the use of condoms during oral sexual encounters.

    Full Text Available The Dining Cryptographer network (or DC-net is a privacy preserving communication protocol devised by David Chaum for anonymous message publication. A very attractive feature of DC-nets is the strength of its security, which is inherent in the protocol and is not dependent on other schemes, like encryption. Unfortunately the DC-net protocol has a level of complexity that causes it to suffer from exceptional communication overhead and implementation difficulty that precludes its use in many real-world use-cases. We have designed and created a DC-net implementation that uses a pure client-server model, which successfully avoids much of the complexity inherent in the DC-net protocol. We describe the theory of DC-nets and our pure client-server implementation, as well as the compromises that were made to reduce the protocol’s level of complexity. Discussion centers around the details of our implementation of DC-net.

  16. Efficient Anonymizations with Enhanced Utility

    Directory of Open Access Journals (Sweden)

    Jacob Goldberger

    2010-08-01

    Full Text Available One of the most well studied models of privacy preservation is k-anonymity. Previous studies of k-anonymization used various utility measures that aim at enhancing the correlation between the original public data and the generalized public data. We, bearing in mind that a primary goal in releasing the anonymized database for datamining is to deducemethods of predicting the private data from the public data, propose a new information-theoretic measure that aims at enhancing the correlation between the generalized public data and the private data. Such a measure significantly enhances the utility of the released anonymized database for data mining. We then proceed to describe a new algorithm that is designed to achieve k-anonymity with high utility, independently of the underlying utility measure. That algorithm is based on a modified version of sequential clustering which is the method of choice in clustering. Experimental comparison with four well known algorithms of k-anonymity show that the sequential clustering algorithm is an efficient algorithm that achieves the best utility results. We also describe a modification of the algorithm that outputs k-anonymizations which respect the additional security measure of l-diversity.

    Bettini, Claudio; Mascetti, Sergio; Wang, X. Sean; Freni, Dario; Jajodia, Sushil

    The problem of protecting user’s privacy in Location-Based Services (LBS) has been extensively studied recently and several defense techniques have been proposed. In this contribution, we first present a categorization of privacy attacks and related defenses. Then, we consider the class of defense techniques that aim at providing privacy through anonymity and in particular algorithms achieving “historical k- anonymity” in the case of the adversary obtaining a trace of requests recognized as being issued by the same (anonymous) user. Finally, we investigate the issues involved in the experimental evaluation of anonymity based defense techniques; we show that user movement simulations based on mostly random movements can lead to overestimate the privacy protection in some cases and to overprotective techniques in other cases. The above results are obtained by comparison to a more realistic simulation with an agent-based simulator, considering a specific deployment scenario.

    Crystal methamphetamine use is a major driver behind high-risk sexual behavior among men who have sex with men (MSM). Prior work suggests a cycle of continued crystal methamphetamine use and high-risk sex due to loss of the ability to enjoy other activities, which appears to be a side effect of this drug. Behavioral activation (BA) is a treatment for depression that involves learning to reengage in life's activities. We evaluated a novel intervention for crystal methamphetamine abuse and high-risk sex in MSM, incorporating 10 sessions of BA with integrated HIV risk reduction counseling (RR). Forty-four subjects were screened, of whom 21 met initial entry criteria. A total of 19 participants enrolled; 16 completed an open-phase study of the intervention. Behavioral assessments were conducted at baseline, 3 months postbaseline, and 6 months postbaseline. Linear mixed effects regression models were fit to assess change over time. Mean unprotected anal intercourse (UAI) episodes decreased significantly from baseline to acute postintervention (β=-4.86; 95% confidence interval [CI]=-7.48, -2.24; p=0.0015) and from baseline to 6 months postbaseline (β=-5.07; 95% CI=-7.85, -2.29; p=0.0017; test of fixed effects χ(2)=16.59; df=2,13; p=0.0002). On average, there was a significant decrease over time in the number of crystal methamphetamine episodes in the past 3 months (χ(2)=22.43; df=2,15; p<0.0001), and the number of days of crystal methamphetamine use in the past 30 days (χ(2)=9.21; df=2,15; p=0.010). Statistically significant reductions in depressive symptoms and poly-substance use were also maintained. Adding behavioral activation to risk reduction counseling for MSM with problematic crystal methamphetamine use may augment the potency of a risk reduction intervention for this population. Due to the small sample size and time intensive intervention, future testing in a randomized design is necessary to determine efficacy, with subsequent effectiveness testing. PMID

    The recently introduced legislation on data retention to aid prosecuting cyber-related crime in Europe also affects the achievable security of systems for anonymous communication on the Internet. We argue that data retention requires a review of existing security evaluations against a new class of realistic adversary models. In particular, we present theoretical results and first empirical evidence for intersection attacks by law enforcement authorities. The reference architecture for our study is the anonymity service AN.ON, from which we also collect empirical data. Our adversary model reflects an interpretation of the current implementation of the EC Directive on Data Retention in Germany.

    Full Text Available Wireless networks and mobile devices, such as mobile phones and GPS receivers, sense and track the movements of people and vehicles, producing society-wide mobility databases. This is a challenging scenario for data analysis and mining. On the one hand, exciting opportunities arise out of discovering new knowledge about human mobile behavior, and thus fuel intelligent info-mobility applications. On other hand, new privacy concerns arise when mobility data are published. The risk is particularly high for GPS trajectories, which represent movement of a very high precision and spatio-temporal resolution: the de-identification of such trajectories (i.e., forgetting the ID of their associated owners is only a weak protection, as generally it is possible to re-identify a person by observing her routine movements. In this paper we propose a method for achieving true anonymity in a dataset of published trajectories, by defining a transformation of the original GPS trajectories based on spatial generalization and k-anonymity. The proposed method offers a formal data protection safeguard, quantified as a theoretical upper bound to the probability of re-identification. We conduct a thorough study on a real-life GPS trajectory dataset, and provide strong empirical evidence that the proposed anonymity techniques achieve the conflicting goals of data utility and data privacy. In practice, the achieved anonymity protection is much stronger than the theoretical worst case, while the quality of the cluster analysis on the trajectory data is preserved.

    Partner notification (PN) is an important method for controlling the AIDS epidemic worldwide. Here, we looked into the differences between two PN counseling modes for HIV (+) men who have sex with men in Taiwan. Using random assignment, we placed 42 of the 84 subjects into the experimental group where they received two sessions of PN counseling, while the control group (42) received only one session. All 84 subjects were single males with an average age of 28.06. The mean number of successful notified partner was 5.38 (SD = 3.44) in the experimental which was statistically significantly higher than 2.81 (SD = 1.62) in the control group (β = 0.650, p = 0.000). The notification success rate was 77.13 % in the experimental and 74.21 % in the control group (IRR 1.039, 95 % CI 0.83-1.30). In the experimental and control group, the average number of the partners accepted an HIV test was 1.86 (SD = 1.58) and 0.79 (SD = 0.66) (β = 0.601, p = 0.000), and 39.74 and 27.27 % of the tested partners were HIV positive (IRR 1.457, 95 % CI 0.69-3.06). The study results may be used to improve the policies and practices for PN and contact follow-up.

    A new protocol for the anonymous communication of quantum information is proposed. The anonymity of the receiver and the privacy of the quantum information are perfectly protected except with exponentially small probability in this protocol. Furthermore, this protocol uses single photons to construct anonymous entanglement instead of multipartite entangled states, and therefore it reduces quantum resources compared with the pioneering work.

  11. Assessing the role of masculinity in the transmission of HIV: a systematic review to inform HIV risk reduction counseling interventions for men who have sex with men.

    Zeglin, Robert J

    2015-10-01

    HIV affects over 1.2 million people in the United States; a substantial number are men who have sex with men (MSM). Despite an abundance of literature evaluating numerous social/structural and individual risk factors associated with HIV for this population, relatively little is known regarding the individual-level role of masculinity in community-level HIV transmission risk. To address this gap, the current analysis systematically reviewed the masculinity and HIV literature for MSM. The findings of 31 sources were included. Seven themes were identified: (1) number of partners, (2) attitudes toward condoms, (3) drug use, (4) sexual positioning, (5) condom decision-making, (6) attitudes toward testing, and (7) treatment compliance. These factors, representing the enactment of masculine norms, potentiate the spread of HIV. The current article aligns these factors into a masculinity model of community HIV transmission. Opportunities for counseling interventions include identifying how masculinity informs a client's cognitions, emotions, and behaviors as well as adapting gender-transformative interventions to help create new conceptualizations of masculinity for MSM clients. This approach could reduce community-level HIV incidence.

    Full Text Available BACKGROUND: Recent studies have shown the public health importance of identifying acute HIV infection (AHI in the men who have sex with men (MSM of China, which has a much higher risk of HIV transmission. However, cost-utility analyses to guide policy around AHI screening are lacking. METHODOLOGY/PRINCIPAL FINDINGS: An open prospective cohort was recruited among MSM living in Liaoning Province, Northeast China. Blood samples and epidemiological information were collected every 10 weeks. Third-generation ELISA and rapid test were used for HIV antibody screening, western blot assay (WB served for assay validation. Antibody negative specimens were tested with 24 mini-pool nucleic acid amplification testing (NAAT. Specimens with positive ELISA but negative or indeterminate WB results were tested with NAAT individually without mixing. A cost-utility analysis of NAAT screening was assessed. Among the 5,344 follow-up visits of 1,765 MSM in 22 months, HIV antibody tests detected 114 HIV chronic infections, 24 seroconverters and 21 antibody indeterminate cases. 29 acute HIV infections were detected with NAAT from 21 antibody indeterminate and 1,606 antibody negative cases. The HIV-1 prevalence and incidence density were 6.6% (95% CI: 5.5-7.9 and 7.1 (95% CI: 5.4-9.2/100 person-years, respectively. With pooled NAAT and individual NAAT strategy, the cost of an HIV transmission averted was $1,480. The addition of NAAT after HIV antibody tests had a cost-utility ratio of $3,366 per gained quality-adjusted life year (QALY. The input-output ratio of NAAT was about 1∶16.9. CONCLUSIONS/SIGNIFICANCE: The HIV infections among MSM continue to rise at alarming rates. Despite the rising cost, adding pooled NAAT to the HIV antibody screening significantly increases the identification of acute HIV infections in MSM. Early treatment and target-oriented publicity and education programs can be strengthened to decrease the risk of HIV transmission and to save medical

    Contemporary antiretroviral therapy (ART) can produce viral suppression of HIV, maintain health, and prevent onward HIV transmission from infected persons to their sexual partners, giving rise to the concept of treatment as prevention. Successful implementation of test-and-treat strategies rests on the early detection of HIV infection through voluntary counseling and testing (VCT) followed by entry and retention in care, ART initiation and adherence, and subsequent viral suppression. In the United States, African American men who have sex with men (MSM) bear a disproportionate burden of HIV and have high rates of undetected and untreated HIV infection. However, little research has examined racial minority MSM's views about HIV testing. In this study, in-depth interviews were conducted with 96 key informants knowledgeable about racial minority MSM as well as 100 African American MSM community members in Milwaukee, Cleveland, and Miami. Most men in the sample were aware of the availability of testing and knew testing locations, but many voiced great personal ambivalence about being tested, feared knowing their HIV status, expressed concern about stigma and loss of confidentiality, and held beliefs indicative of medical mistrust. Participants did not spontaneously cite benefits of being tested, risk reduction behavior changes made as a consequence of testing, nor the benefits of testing to get early medical care for HIV infection. There is a gap between the public health field's perception of testing benefits and the beliefs about testing held by racial minority MSM in this sample. To increase the desired outcomes from VCT for minority MSM, VCT promotion should address the concerns of African American MSM and underscore the benefits of early entry into medical care.

    Full Text Available OBJECTIVE: To explore the feasibility of using Internet outreach to encourage men who have sex with men (MSM to get tested for HIV at voluntary counseling and testing (VCT clinics in Beijing and Urumqi, China. METHODS: From June to August 2007, two volunteers contacted MSM using instant messaging, online chat rooms, mobile phone, and e-mail (active recruitment. Banners with study information were put at the front pages of three major Chinese gay websites (passive recruitment. Those contacted were offered a modest financial incentive to seek HIV testing at existing VCT clinics. Those who subsequently sought HIV testing services at VCT clinics and provided informed consent completed a questionnaire and a blood draw to test for HIV and syphilis. RESULTS: A total of 3,332 MSM were contacted and 429 attended VCT clinics. One out of every 4 men that were recruited through instant messaging actually went for HIV testing, while the recruitment yields for online gay chat rooms, mobile phone contact, and email were 1∶6, 1∶10, and 1∶140, respectively. The majority of participants (80%, 317/399 reported being motivated to seek HIV testing out of concern for their health, and only 3% (11/399 reported being motivated by the financial incentive. Active recruitment tend to recruit MSM who are younger (X(2 = 11.400, P = 0.001, never tested for HIV (X(2 = 4.281, P = 0.039, tested less often (X(2 = 5.638, P = 0.018. CONCLUSION: Internet outreach is a promising way to encourage MSM to seek HIV testing at existing VCT clinics. Active recruitment can target MSM who are younger, never tested for HIV and tested less often.

    2012-01-01

    Distributed Hash Table (DHT) lookup is a core technique in structured peer-to-peer (P2P) networks. Its decentralized nature introduces security and privacy vulnerabilities for applications built on top of them; we thus set out to design a lookup mechanism achieving both security and anonymity, heretofore an open problem. We present Octopus, a novel DHT lookup which provides strong guarantees for both security and anonymity. Octopus uses attacker identification mechanisms to discover and remove malicious nodes, severely limiting an adversary's ability to carry out active attacks, and splits lookup queries over separate anonymous paths and introduces dummy queries to achieve high levels of anonymity. We analyze the security of Octopus by developing an event-based simulator to show that the attacker discovery mechanisms can rapidly identify malicious nodes with low error rate. We calculate the anonymity of Octopus using probabilistic modeling and show that Octopus can achieve near-optimal anonymity. We evaluate ...

    Hendrickx, Julien M; Tsitsiklis, John N

    2010-01-01

    We propose a model for deterministic distributed function computation by a network of identical and anonymous nodes. In this model, each node has bounded computation and storage capabilities that do not grow with the network size. Furthermore, each node only knows its neighbors, not the entire graph. Our goal is to characterize the class of functions that can be computed within this model. In our main result, we provide a necessary condition for computability which we show to be nearly sufficient, in the sense that every function that violates this condition can at least be approximated. The problem of computing suitably rounded averages in a distributed manner plays a central role in our development; we provide an algorithm that solves it in time that grows quadratically with the size of the network.

    2009-01-01

    Electronic Product Code (EPC) is the basis of a pervasive infrastructure for the automatic identification of objects on supply chain applications (e.g., pharmaceutical or military applications). This infrastructure relies on the use of the (1) Radio Frequency Identification (RFID) technology to tag objects in motion and (2) distributed services providing information about objects via the Internet. A lookup service, called the Object Name Service (ONS) and based on the use of the Domain Name System (DNS), can be publicly accessed by EPC applications looking for information associated with tagged objects. Privacy issues may affect corporate infrastructures based on EPC technologies if their lookup service is not properly protected. A possible solution to mitigate these issues is the use of online anonymity. We present an evaluation experiment that compares the of use of Tor (The second generation Onion Router) on a global ONS/DNS setup, with respect to benefits, limitations, and latency.

    Directory of Open Access Journals (Sweden)

    Chiedu Ifekandu

    2014-11-01

    Full Text Available Introduction: Men who have sex with men (MSM are at increased risk of HIV and other STI infections in Nigeria. This is because MSM are afraid to seek medical help because the healthcare workers in various facilities are afraid of the consequences if they provide services for MSM citing the law as a reason not to intervene. MSM in northern states of Nigeria are facing double-jeopardy because the few international partners working in MSM in Nigeria are pulling out of these volatile areas because of the fear of attacks by the Boko Haram and the Nigerian law enforcement agencies. Objectives: The intervention was conducted to promote affordable and sustainable HIV care and treatment for MSM in Nigeria. Methods: This intervention was conducted in the Boko Haram ravaged cities of Kano and Maiduguri (North-East Nigeria. Twenty MSM-key influencers from the two cities were identified and trained on HIV counselling and testing, caregivers, case managers and on initiation process for ARV treatment for new HIV+MSM as well as ethical considerations. Results: The mean age of the key influencers was 24 years +/−SD. Each of the trained 20 key influencers reached 20 MSM-peer with condom promotion, HCT, referral to identified MSM-community health centers and follow-up/caregiving within the space of one month. The project was able to reach 400 MSM in the two cities. 89% of the peers consented to HCT. HIV prevalence among the participants was at 18%. The project recorded ARV-successful referral to healthcare facilities for the respondents that tested positive. The key influencers have been following up for ARV-adherence. Conclusions: Use of community members should be promoted for sustainability and ownership. It also helps in eradicating socio-cultural barrier to HIV intervention for MSM. Moreover, this proves to be one of the safest and affordable methods of reaching MSM in Nigeria in this ugly time of legalization of homophobia in the country's constitution.

In this paper, we propose a quantum anonymous voting protocol assisted by two kinds of entangled quantum states. Particularly, we provide a mechanism of opening and permuting the ordered votes of all the voters in an anonymous manner; any party who is interested in the voting results can acquire a permutation copy and then obtains the voting result through a simple calculation. Unlike all previous quantum works on anonymous voting, our quantum anonymous protocol possesses the properties of privacy, self-tallying, nonreusability, verifiability, and fairness at the same time. In addition, we demonstrate that the entanglement of the quantum states used in our protocol makes an attack from an outside eavesdropper and inside dishonest voters impossible. We also generalize our protocol to execute the task of anonymous multiparty computation, such as anonymous broadcast and anonymous ranking.

We found a positive correlation between risk perception and HIV infection in this study. Clients with high HIV risk perception have 17x the odds of testing HIV positive compared to low risk clients. High HIV risk perception was significantly associated with multiple sex partners, multiple types of sex partners, alcohol use before intercourse, unprotected sex beyond 6 months, and inconsistent condom use during anal sex compared to low risk clients. There were no statistically significant differences between medium risk and unsure risk clients compared to low risk clients. Strategies should be targeted towards change in sexual practices among those who are perceived to be at high risk.

  20. Towards a Theory of Anonymous Networking

    Ghaderi, J

    2009-01-01

    The problem of anonymous networking when an eavesdropper observes packet timings in a communication network is considered. The goal is to hide the identities of source-destination nodes, and paths of information flow in the network. One way to achieve such an anonymity is to use mixers. Mixers are nodes that receive packets from multiple sources and change the timing of packets, by mixing packets at the output links, to prevent the eavesdropper from finding sources of outgoing packets. In this paper, we consider two simple but fundamental scenarios: double input-single output mixer and double input-double output mixer. For the first case, we use the information-theoretic definition of the anonymity, based on average entropy per packet, and find an optimal mixing strategy under a strict latency constraint. For the second case, perfect anonymity is considered, and a maximal throughput strategy with perfect anonymity is found that minimizes the average delay.

    2014-08-01

    Sensitive biomedical data is often collected from distributed sources, involving different information systems and different organizational units. Local autonomy and legal reasons lead to the need of privacy preserving integration concepts. In this article, we focus on anonymization, which plays an important role for the re-use of clinical data and for the sharing of research data. We present a flexible solution for anonymizing distributed data in the semi-honest model. Prior to the anonymization procedure, an encrypted global view of the dataset is constructed by means of a secure multi-party computing (SMC) protocol. This global representation can then be anonymized. Our approach is not limited to specific anonymization algorithms but provides pre- and postprocessing for a broad spectrum of algorithms and many privacy criteria. We present an extensive analytical and experimental evaluation and discuss which types of methods and criteria are supported. Our prototype demonstrates the approach by implementing k-anonymity, ℓ-diversity, t-closeness and δ-presence with a globally optimal de-identification method in horizontally and vertically distributed setups. The experiments show that our method provides highly competitive performance and offers a practical and flexible solution for anonymizing distributed biomedical datasets. PMID:24333850

    Full Text Available Social media and social networks are embedded in our society to a point that could not have been imagined only ten years ago. Facebook, LinkedIn, and Twitter are already well known social networks that have a large audience in all age groups. The amount of data that those social sites gather from their users is continually increasing and this data is very valuable for marketing, research, and various other purposes. At the same time, this data usually contain a significant amount of sensitive information which should be protected against unauthorized disclosure. To protect the privacy of individuals, this data must be anonymized such that the risk of re-identification of specific individuals is very low. In this paper we study if anonymized social networks preserve existing communities from the original social networks. To perform this study, we introduce two approaches to measure the community preservation between the initial network and its anonymized version. In the first approach we simply count how many nodes from the original communities remained in the same community after the processes of anonymization and de-anonymization. In the second approach we consider the community preservation for each node individually. Specifically, for each node, we compare the original and final communities to which the node belongs. To anonymize social networks we use two models, namely, k-anonymity for social networks and k-degree anonymity. To determine communities in social networks we use an existing community detection algorithm based on modularity quality function. Our experiments on publically available datasets show that anonymized social networks satisfactorily preserve the community structure of their original networks.

    Full Text Available Abstract Background This investigation describes features of patients undergoing in vitro fertilisation (IVF and embryo transfer (ET where both gametes were obtained from anonymous donors. Methods Gamete unsuitability or loss was confirmed in both members of seven otherwise healthy couples presenting for reproductive endocrinology consultation over a 12-month interval in Ireland. IVF was undertaken with fresh oocytes provided by anonymous donors in Ukraine; frozen sperm (anonymous donor was obtained from a licensed tissue establishment. For recipients, saline-enhanced sonography was used to assess intrauterine contour with endometrial preparation via transdermal estrogen. Results Among commissioning couples, mean±SD female and male age was 41.9 ± 3.7 and 44.6 ± 3.5 yrs, respectively. During this period, female age for non dual anonymous gamete donation IVF patients was 37.9 ± 3 yrs (p Conclusions Mean age of females undergoing dual anonymous donor gamete donation with IVF is significantly higher than the background IVF patient population. Even when neither partner is able to contribute any gametes for IVF, the clinical pregnancy rate per transfer can be satisfactory if both anonymous egg and sperm donation are used concurrently. Our report emphasises the role of pre-treatment counselling in dual anonymous gamete donation, and presents a coordinated screening and treatment approach in IVF where this option may be contemplated.

  5. Providing Group Anonymity Using Wavelet Transform

    CERN Document Server

    Chertov, Oleg

    2010-01-01

    Providing public access to unprotected digital data can pose a threat of unwanted disclosing the restricted information. The problem of protecting such information can be divided into two main subclasses, namely, individual and group data anonymity. By group anonymity we define protecting important data patterns, distributions, and collective features which cannot be determined through analyzing individual records only. An effective and comparatively simple way of solving group anonymity problem is doubtlessly applying wavelet transform. It's easy-to-implement, powerful enough, and might produce acceptable results if used properly. In the paper, we present a novel method of using wavelet transform for providing group anonymity; it is gained through redistributing wavelet approximation values, along with simultaneous fixing data mean value and leaving wavelet details unchanged (or proportionally altering them). Moreover, we provide a comprehensive example to illustrate the method.

    We consider networks of anonymous sensors and address the problem of constructing routes for the delivery of information from a group of sensors in response to a query by a sink. In order to circumvent the restrictions imposed by anonymity, we rely on using the power level perceived by the sensors in the query from the sink. We introduce a simple distributed algorithm to achieve the building of routes to the sink and evaluate its performance by means of simulations.

    Lee, Michael Z; Dunn, Alan M; Katz, Jonathan; Waters, Brent; Witchel, Emmett

    2013-12-31

    We present the design, security proof, and implementation of an anonymous subscription service. Users register for the service by providing some form of identity, which might or might not be linked to a real-world identity such as a credit card, a web login, or a public key. A user logs on to the system by presenting a credential derived from information received at registration. Each credential allows only a single login in any authentication window, or epoch. Logins are anonymous in the sense that the service cannot distinguish which user is logging in any better than random guessing. This implies unlinkability of a user across different logins. We find that a central tension in an anonymous subscription service is the service provider's desire for a long epoch (to reduce server-side computation) versus users' desire for a short epoch (so they can repeatedly "re-anonymize" their sessions). We balance this tension by having short epochs, but adding an efficient operation for clients who do not need unlinkability to cheaply re-authenticate themselves for the next time period. We measure performance of a research prototype of our protocol that allows an independent service to offer anonymous access to existing services. We implement a music service, an Android-based subway-pass application, and a web proxy, and show that adding anonymity adds minimal client latency and only requires 33 KB of server memory per active user.

    2014-01-01

    We tested a couples HIV testing and counseling (CHTC) intervention with male couples in Atlanta by randomizing eligible couples to receive either CHTC or separate individual voluntary HIV counseling and testing (iVCT). To evaluate the acceptability and safety of CHTC, main outcomes were satisfaction with the intervention and the proportions of couples reporting intimate partner violence (IPV) and relationship dissolution after the service. The results indicated that the service was very acceptable to men (median 7-item index of satisfaction was 34 for CHTC and 35 for iVCT, P = .4). There was no difference in either incident IPV (22% versus 17% for CHTC and iVCT, respectively, P = .6) or relationship dissolution (42% versus 51% for CHTC and iVCT, respectively, P = .5). Based on the preliminary data, CHTC is safe for male couples, and it is equally acceptable to iVCT for men who have main partners.

  13. Anonymous Fingerprinting with Robust QIM Watermarking Techniques

    Directory of Open Access Journals (Sweden)

    R. L. Lagendijk

    2007-12-01

    Full Text Available Fingerprinting is an essential tool to shun legal buyers of digital content from illegal redistribution. In fingerprinting schemes, the merchant embeds the buyer's identity as a watermark into the content so that the merchant can retrieve the buyer's identity when he encounters a redistributed copy. To prevent the merchant from dishonestly embedding the buyer's identity multiple times, it is essential for the fingerprinting scheme to be anonymous. Kuribayashi and Tanaka, 2005, proposed an anonymous fingerprinting scheme based on a homomorphic additive encryption scheme, which uses basic quantization index modulation (QIM for embedding. In order, for this scheme, to provide sufficient security to the merchant, the buyer must be unable to remove the fingerprint without significantly degrading the purchased digital content. Unfortunately, QIM watermarks can be removed by simple attacks like amplitude scaling. Furthermore, the embedding positions can be retrieved by a single buyer, allowing for a locally targeted attack. In this paper, we use robust watermarking techniques within the anonymous fingerprinting approach proposed by Kuribayashi and Tanaka. We show that the properties of an additive homomorphic cryptosystem allow for creating anonymous fingerprinting schemes based on distortion compensated QIM (DC-QIM and rational dither modulation (RDM, improving the robustness of the embedded fingerprints. We evaluate the performance of the proposed anonymous fingerprinting schemes under additive-noise and amplitude-scaling attacks.

  14. Secure Electronic Cash Scheme with Anonymity Revocation

    2016-01-01

    Full Text Available In a popular electronic cash scheme, there are three participants: the bank, the customer, and the merchant. First, a customer opens an account in a bank. Then, he withdraws an e-cash from his account and pays it to a merchant. After checking the electronic cash’s validity, the merchant accepts it and deposits it to the bank. There are a number of requirements for an electronic cash scheme, such as, anonymity, unforgeability, unreusability, divisibility, transferability, and portability. Anonymity property of electronic cash schemes can ensure the privacy of payers. However, this anonymity property is easily abused by criminals. In 2011, Chen et al. proposed a novel electronic cash system with trustee-based anonymity revocation from pairing. On demand, the trustee can disclose the identity for e-cash. But, in this paper we point out that Chen et al.’s scheme is subjected to some drawbacks. To contribute secure electronic cash schemes, we propose a new offline electronic cash scheme with anonymity revocation. We also provide the formally security proofs of the unlinkability and unforgeability. Furthermore, the proposed scheme ensures the property of avoiding merchant frauds.

    Full Text Available Do the deviant acts carried out by the collective known as Anonymous qualify as vigilante activity, and if so, can they be justified? Addressing this question helps expose the difficulties of morally evaluating technologically enabled deviance. Anonymous is a complex, fluid actor but not as mysterious as popularly portrayed. Under a definition of vigilantism that includes reprobative punishment rather than violence as a key element, Anonymous are vigilantes. Many of its Ops can be justified in view of the mismatch between formal norm enforcement practice and Internet natives’ experience of it. Anons are more like eco-warriors than terrorists. While their actions are contentious, their force is framed in a vision of common good that is not unreasonable. Engaging with online deviants is shown to be a productive way of identifying the weaknesses in concepts underpinning moral evaluation of Internet-enabled phenomena.

  2. Automatic Control of Configuration of Web Anonymization

    Directory of Open Access Journals (Sweden)

    Tomas Sochor

    2013-01-01

    Full Text Available Anonymization of the Internet traffic usually hides details about the request originator from the target server. Such a disguise might be required in some situations, especially in the case of web browsing. Although the web traffic anonymization is not a part of the http specification, it could be achieved using a certain extra tool. Significant deceleration of anonymized traffic compared to normal traffic is inevitable but it can be controlled in some cases as this article suggests. The results presented here focus on measuring the parameters of such deceleration in terms of response time, transmission speed and latency and proposing the way how to control it. This study focuses on TOR primarily because recent studies have concluded that other tools (like I2P and JAP provide worse service. Sets of 14 file locations and 30 web pages have been formed and the latency, response time and transmission speed during the page or file download were measured repeatedly both with TOR active in various configurations and without TOR. The main result presented here comprises several ways how to improve the TOR anonymization efficiency and the proposal for its automatic control. In spite of the fact that efficiency still remains too low compared to normal web traffic for ordinary use, its automatic control could make TOR a useful tool in special cases.

  3. Anonymous publication of sensitive transactional data

    KAUST Repository

    Ghinita, Gabriel

    2011-02-01

    Existing research on privacy-preserving data publishing focuses on relational data: in this context, the objective is to enforce privacy-preserving paradigms, such as k-anonymity and ℓ-diversity, while minimizing the information loss incurred in the anonymizing process (i.e., maximize data utility). Existing techniques work well for fixed-schema data, with low dimensionality. Nevertheless, certain applications require privacy-preserving publishing of transactional data (or basket data), which involve hundreds or even thousands of dimensions, rendering existing methods unusable. We propose two categories of novel anonymization methods for sparse high-dimensional data. The first category is based on approximate nearest-neighbor (NN) search in high-dimensional spaces, which is efficiently performed through locality-sensitive hashing (LSH). In the second category, we propose two data transformations that capture the correlation in the underlying data: 1) reduction to a band matrix and 2) Gray encoding-based sorting. These representations facilitate the formation of anonymized groups with low information loss, through an efficient linear-time heuristic. We show experimentally, using real-life data sets, that all our methods clearly outperform existing state of the art. Among the proposed techniques, NN-search yields superior data utility compared to the band matrix transformation, but incurs higher computational overhead. The data transformation based on Gray code sorting performs best in terms of both data utility and execution time. © 2006 IEEE.

    2005-01-01

    Electronic check systems, as one of electronic payment systems, are more desirable than other electronic cash systems. In the system, only a single check is used to pay any price that is not more than the face value. The main problem in check systems is to design an efficient refund mechanism that makes refund checks undistinguished from initial checks during payment and deposit. The problem of anonymity control also called fairness is also an important issue in check systems. All check systems yet are unconditional anonymity that opens the door to misuse for crime such as laundering and blackmailing. In this paper, the notion of anonymity revocation is introduced to electronic check system for the first time, and a model of fair electronic check system is proposed. An efficient fair online electronic check system with reusable refund is presented. In the system, a passive trustee is employed to revoke the anonymity of un-honest users. Moreover, the system solves the reusability problem of refunds thanks to the RSA-based partially signature. The system is efficient and meets all basic security requirements.

    Vehicular networks have attracted extensive attention in recent years for their promises in improving safety and enabling other value-added services. Most previous work focuses on designing the media access and physical layer protocols.Privacy issues in vehicular systems have not been well addressed. We argue that privacy is a user-specific concept, and a good privacy protection mechanism should allow users to select the levels of privacy they wish to have. To address this requirement, we propose an adaptive anonymous authentication mechanism that can trade off the anonymity level with computational and communication overheads (resource usage). This mechanism, to our knowledge, is the first effort on adaptive anonymous authentication. The resources used by our protocol are few. A high traffic volume of 2000 vehicles per hour consumes about 60kbps bandwidth, which is less than one percent of the bandwidth of DSRC (Dedicated Short Range Communications). By using adaptive anonymity, the protocol response time can further be improved 2~4 times with lessthan 20% bandwidth overheads.

    To assess the potential for HIV acquisition among men who have sex with men (MSM) in Guangzhou, China, we conducted a cross-sectional, anonymous, face-to-face survey of MSM in the metropolitan area of Guangzhou, China. As a pilot recruitment for a cohort study, participants were recruited by convenience sampling through newspaper and television advertising, website information, and respondent referral. Blood samples were tested for HIV, hepatitis B (HBV), hepatitis C (HCV), and syphilis. Client-centered HIV and STD counseling was provided.A total of 201 MSM were interviewed and 200 blood samples were tested. The prevalence of HIV antibody was 0% (97.5% CI 0-1.8%); 17.5% of MSM were HBV surface antigen positive; 1.0% had HCV antibodies; 10.5% had antibodies to syphilis. Syphilis seropositivity was associated with sex with a foreign MSM in the last six months and 10.4% reported sex with a foreign MSM overall. The majority (54.7%) reported unprotected anal sex with other men. Nearly one-third (31.8%) had regular female partners; 25.9% were currently married to a woman; 6% had casual female partners; 4.5% had sex with a female sex worker; 4.5% had sex with a male sex worker; and 12.9% had unprotected vaginal sex and unprotected anal sex with a man in the past six months. Only one MSM reported injection drug use (0.5%). The currently low prevalence of HIV but high level of unprotected anal sex, high prevalence of syphilis infection, and sexual networks that include foreign MSM point to a transient window for HIV prevention among MSM in Guangzhou. We recognize challenges to recruiting a representative sample of MSM and retaining them in longitudinal cohort studies. PMID:16802197

    Personalized medicine continues to expand with the development and increasing use of genome-based testing. While these advances present new opportunities for diagnosis and risk assessment, they also present challenges to clinical delivery. Genetic counselors will play an important role in ushering in this new era of testing; however, it will warrant a shift from traditional genetic counseling to "genomic counseling." This shift will be marked by a move from reactive genetic testing for diagnosis of primarily single-gene diseases to proactive genome-based testing for multiple complex diseases for the purpose of disease prevention. It will also require discussion of risk information for a number of diseases, some of which may have low relative risks or weak associations, and thus, may not substantially impact clinical care. Additionally, genomic counselors will expand their roles, particularly in the area of health promotion to reduce disease risk. This additional role will require a style of counseling that is more directive than traditional counseling and require greater knowledge about risk reducing behaviors and disease screening.

    The use of non-anonymized human genome data is becoming increasingly popular in research. Here we review the proceedings of a special meeting on this topic that took place at European Molecular Biology Organization (EMBO) in December 2014. The main points discussed centered on how to achieve 'anonymity,' 'trust,' and 'protection of data' in relation to new genomic technologies and research. Following our report of this meeting, we also raise three further issues for future consideration: the harmonization of international law in relation to genetic data protection; the complex issues around the 'dividual' nature of genetic data; and the growing commercial value of personal data. In conclusion, we stress the importance of scientists working in the area of genomic research engaging in interdisciplinary collaborations with humanities and social science scholars and addressing these complicated issues.

    2011-01-01

    Nowadays, it is a common practice to protect various types of statistical data before publishing them for different researches. For instance, when conducting extensive demographic surveys such as national census, the collected data should be at least depersonalized to guarantee proper level of privacy preservation. In practice, even more complicated methods of data protection need to be used. All these methods can be generally divided into two classes. The first ones aim at providing individual data anonymity, whereas the other ones are focused on protecting information about a group of respondents. In this paper, we propose a novel technique of providing group anonymity in statistical data using singular spectrum analysis (SSA).Also, we apply SSA to defining hidden patterns in demographic data distribution.

    2011-01-01

    Researchers often face the problem of needing to protect the privacy of subjects while also needing to integrate data that contains personal information from diverse data sources in order to conduct their research. The advent of computational social science and the enormous amount of data about people that is being collected makes protecting the privacy of research subjects evermore important. However, strict privacy procedures can make joining diverse sources of data that contain information about specific individual behaviors difficult. In this paper we present a procedure to keep information about specific individuals from being "leaked" or shared in either direction between two sources of data. To achieve this goal, we randomly assign individuals to anonymous groups before combining the anonymized information between the two sources of data. We refer to this method as the Yahtzee procedure, and show that it performs as expected theoretically when we apply it to data from Facebook and public voter records.

    Full Text Available Releasing person specific data could potentially reveal the sensitive information of an individual. kanonymityis an approach for protecting the individual privacy where the data is formed into set ofequivalence classes in which each class share the same values. Among several methods, local recodingbased generalization is an effective method to accomplish k-anonymization. In this paper, we proposed aminimum spanning tree partitioning based approach to achieve local recoding. We achieve it in twophases. During the first phase, MST is constructed using concept hierarchical and the distances amongdata points are considered as the weights of MST and in the next phase we generate the equivalence classesadhering to the anonymity requirement. Experiments show that our proposed local recoding frameworkproduces better quality in published tables than existing Mondrian global recoding and k-memberclustering approaches.

    Full Text Available There is an increase activity in research to improve the current electronic payment system which is parallel with the progress of internet. Electronic cash system is a cryptographic payment system which offers anonymity during withdrawal and purchase. Electronic cash displays serial numbers which can be recorded to allow further tracing. Contrary to their physical counterparts, e-cash have an inherent limitation; they are easy to copy and reuse (double-spending. An observer is a tamper-resistant device, issued by the Internet bank, which is incorporated with the Internet user’s computer that prevents double-spending physically, i.e., the user has no access to her e-cash and therefore he cannot copy them. In this paper, we shall present an anonymous electronic cash scheme on the internet which incorporates tamper-resistant device with user-module.

    2012-04-01

    Full Text Available Decreased privacy is an unavoidable consequence in the drive to make the world a more secure, safer place, according to some analysts. In the on-line world, the conflict between privacy and security manifests itself in a debate between anonymity and accountability. Balance between Anonymity and Accountability is a major concern in web based transactions. The protection of users’ privacy when performing web-based transactions is an important factor in the acceptance and use of Internet and web services. There is a tremendous improvement in the automation of the way we pay for goods and services by the variety and growth of electronic banking services available to the consumers. Hence there is a need for the ultimate structure of the new electronic transaction system that has a substantial impact on the personal privacy as well as on the nature and extent of criminal use of E- transactions. This paper presents an approach for such structure.

    This paper compares the attractiveness of floor trading and anonymous electronic trading systems. It is argued that in times of low information intensity the insight into the order book of the electronic trading system provides more valuable information than floor trading, but in times of high information intensity the reverse is true. Thus, the electronic system's market share in trading activity should decline in times of high information intensity. This hypothesis is tested by data on BUND...

  1. The BitTorrent Anonymity Marketplace

    CERN Document Server

    Nielson, Seth James

    2011-01-01

    The very nature of operations in peer-to-peer systems such as BitTorrent exposes information about participants to their peers. Nodes desiring anonymity, therefore, often chose to route their peer-to-peer traffic through anonymity relays, such as Tor. Unfortunately, these relays have little incentive for contribution and struggle to scale with the high loads that P2P traffic foists upon them. We propose a novel modification for BitTorrent that we call the BitTorrent Anonymity Marketplace. Peers in our system trade in k swarms obscuring the actual intent of the participants. But because peers can cross-trade torrents, the k-1 cover traffic can actually serve a useful purpose. This creates a system wherein a neighbor cannot determine if a node actually wants a given torrent, or if it is only using it as leverage to get the one it really wants. In this paper, we present our design, explore its operation in simulation, and analyze its effectiveness. We demonstrate that the upload and download characteristics of c...

  2. Universally composable anonymous Hash certification model

    2007-01-01

    Ideal function is the fundamental component in the universally composable security model. However, the certification ideal function defined in the universally composable security model realizes the identity authentication by binding identity to messages and the signature, which fails to characterize the special security requirements of anonymous authentication with other kind of certificate. Therefore,inspired by the work of Marten, an anonymous hash certification ideal function and a more universal certificate CA model are proposed in this paper. We define the security requirements and security notions for this model in the framework of universal composable security and prove in the plain model (not in the random-oracle model) that these security notions can be achieved using combinations of a secure digital signature scheme, a symmetrical encryption mechanism, a family of pseudorandom functions, and a family of one-way collision-free hash functions. Considering the limitation of wireless environment and computation ability of wireless devices, this anonymous Hash certification ideal function is realized by using symmetry primitives.

  3. The long path to pregnancy: early experience with dual anonymous gamete donation in a European in vitro fertilisation referral centre

    Sills, Eric Scott

    2010-08-11

    Abstract Background This investigation describes features of patients undergoing in vitro fertilisation (IVF) and embryo transfer (ET) where both gametes were obtained from anonymous donors. Methods Gamete unsuitability or loss was confirmed in both members of seven otherwise healthy couples presenting for reproductive endocrinology consultation over a 12-month interval in Ireland. IVF was undertaken with fresh oocytes provided by anonymous donors in Ukraine; frozen sperm (anonymous donor) was obtained from a licensed tissue establishment. For recipients, saline-enhanced sonography was used to assess intrauterine contour with endometrial preparation via transdermal estrogen. Results Among commissioning couples, mean±SD female and male age was 41.9 ± 3.7 and 44.6 ± 3.5 yrs, respectively. During this period, female age for non dual anonymous gamete donation IVF patients was 37.9 ± 3 yrs (p < 0.001). Infertility duration was ≥3 yrs for couples enrolling in dual gamete donation, and each had ≥2 prior failed fertility treatments using native oocytes. All seven recipient couples proceeded to embryo transfer, although one patient had two transfers. Clinical pregnancy was achieved for 5\\/7 (71.4%) patients. Non-transferred cryopreserved embryos were available for all seven couples. Conclusions Mean age of females undergoing dual anonymous donor gamete donation with IVF is significantly higher than the background IVF patient population. Even when neither partner is able to contribute any gametes for IVF, the clinical pregnancy rate per transfer can be satisfactory if both anonymous egg and sperm donation are used concurrently. Our report emphasises the role of pre-treatment counselling in dual anonymous gamete donation, and presents a coordinated screening and treatment approach in IVF where this option may be contemplated.

    Retrospective data were entered anonymously by 1,521 adult women using a computer-assisted self-interview. Thirty-one participants were victims of sister-sister incest, 40 were victims of brother-sister incest, 19 were victims of father-daughter incest, 8 were victims of sexual abuse by an adult female (including one mother), and 232 were victims of sexual abuse by an adult male other than their father before reaching 18 years of age. The rest (1,203) served as controls. The victims of sister-sister incest had significantly more problematic outcomes than controls on many measures as adults. Victims of sister-sister incest were more depressed and more likely than controls to be distant from the perpetrator-sister and to have traded sex for money, experienced an unplanned pregnancy, engaged in four different types of masturbation, and engaged in 13 different same-sex behaviors. Our findings were consistent with other reports of early eroticization and persistent hypereroticization of incest victims.

    Anonymous transmission is an interesting and crucial issue in computer communication area, which plays a supplementary role to data privacy. In this paper, we put forward a privacy preserving quantum anonymous transmission protocol based on entanglement relay, which constructs anonymous entanglement from EPR pairs instead of multi-particle entangled state, e.g. GHZ state. Our protocol achieves both sender anonymity and receiver anonymity against an active adversary and tolerates any number of corrupt participants. Meanwhile, our protocol obtains an improvement in efficiency compared to quantum schemes in previous literature.

    2014-01-01

    Many teaching hospitals employ a care team structure composed of a broad range of healthcare providers with different skill sets. Each member of this team has a distinct role and a different level of training ranging from attending physician to resident, intern, and medical student. Often times, these different roles lead to greater complexity and confusion for both patients and nursing staff. It has been demonstrated that patients have a great degree of difficulty in identifying members of their care team. This anonymity also exists between nursing staff and other care providers. In order to better understand the magnitude of anonymity within the teaching hospital, a ten-question survey was sent to nurses across three different departments. Results from this survey demonstrated that 71% of nurses are "Always" or "Often" able to identify which care team is responsible for their patients, while 79% of nurses reported that they either "Often" or "Sometimes" page a provider who is not currently caring for a given patient. Furthermore, 33% of nurses felt that they were either "Rarely" or "Never" able to recognize, by face and name, attending level providers. Residents were "Rarely" or "Never" recognized by face and name 37% of the time, and interns 42% of the time. Contacting the wrong provider repeatedly leads to de facto delays in medication, therapy, and diagnosis. Additionally, these unnecessary interruptions slow workflow for both nurses and members of the care team, making hospital care less efficient and safe overall. Technological systems should focus on reducing anonymity within the hospital in order to enhance healthcare delivery. PMID:25114570

    2007-01-01

    The problem of publishing personal data without giving up privacy is increasingly important. An interesting formalization is the $k$-anonymization, where all rows in a table are clustered in sets of at least $k$ records, and all the entries for which records in the same cluster have different values are suppressed. The problem has been shown to be NP-hard when the records values are over a ternary alphabet and $k=3$. In this paper we show that the problem is not only NP-hard, but also APX-hard, when the records values are over a binary alphabet and $k=3$.

  9. Ethical attitudes of German specialists in reproductive medicine and legal regulation of preimplantation sex selection in Germany.

    Directory of Open Access Journals (Sweden)

    Full Text Available BACKGROUND: Because of its ethical and social implications, preimplantation sex selection is frequently the subject of debates. METHODS: In 2006, we surveyed specialists in reproductive medicine in Germany using an anonymous questionnaire, including sociodemographic data and questions regarding ethical problems occurring in the practice of reproductive medicine. Most questions focused on preimplantation sex selection, including 10 case vignettes, since these enabled us to describe the most difficult and ethically controversial situations. This is the first survey among specialists in reproductive medicine regarding this topic in Germany. RESULTS: 114 specialists in reproductive medicine participated, 72 males (63% and 42 females (37%, average age was 48 years (age range 29-67 years. The majority of respondents (79% favoured a regulation that limits the use of preimplantation sex selection only for medical reasons, such as X-linked diseases (including 18%: summoning an ethics commission for every case. A minority of 18% approved of the use of sex selection for non-medical reasons (4% generally and further 14% for family balancing. 90% had received obvious requests from patients. The highest approval (46% got the counselling guideline against a preimplantation sex selection and advising a normal pregnancy, if preimplantation sex selection would be allowed in Germany. The majority (67% was opposed the personal use of preimplantation sex selection for non-medical reasons, but would think about it in medical cases. In opposite to woman, 14% of the men were in favour of personal use for non-medical reasons (p=0,043. 25% of specialists in reproductive medicine feared that an allowance of preimplantation sex selection would cause a shift in the sex ratio. CONCLUSIONS: The majority of German specialists in reproductive medicine opposes preimplantation sex selection for non-medical reasons while recommending preimplantation sex selection for medical

    1996-03-01

    Background: Travelers to the tropics have been reported to comply poorly with recommendations regarding malaria and AIDS. This study addresses the problem of influencing travelers' behavior through different approaches to conveying advice. Method: 3509 people attending a large travel clinic were randomly allocated to different interventions, including brochures about the implications of "sex tourism" and the possibility of participating in a contest assessing knowledge of malaria and AIDS. A comparison group (n = 607) of travelers to Kenya was contacted at an airport. Anonymous, self-administered questionnaires were sent to all travelers after their return. Results: Compliance with chemosuppressive regimen for malaria was 87%. Well-informed travelers did not protect themselves more efficiently against malaria. The efficacy of a given intervention was found to vary according to the age, sex, or travel experience of the participants. Of travelers, 51% reported casual sex abroad (M/F: 69/31). Thirty-eight percent of these contacts were unprotected. Casual sex abroad and condom use were correlated with a history of casual sex in the home country. Condom use was especially low in young women, who were also more likely to have casual sex with fellow travelers than with local partners. Eight percent of the "sex tourism" brochure readers had engaged in casual sex with local partners (all travelers, 4%). Conclusions: Lack of knowledge does not appear to be the problem. Travelers need to be motivated to put their knowledge into practice. Our results suggest that risks relating to malaria and AIDS are perceived in a different manner and that counseling should be individualized. Contest questions can help start a discussion on ethical and health-responsible behavior. The target group of the "sex tourism" brochure was reached, but their behavior appears not to have changed. Objective criteria can help physicians recognize "high-risk" travelers. Travelers need to be made aware

    Do you consider browsing the Internet to be your private business? When visiting random web-sites, how far do you assume you are anonymous? Would it matter to you that Google or Facebook can profile your browsing behaviour in order to better target you with advertisements? Did you notice that you already get targeted ads when you are logged on to Google or Facebook even if you are visiting completely different websites? If matters to you, note that browsing anonymously on the Internet is far from easy.   When you are connected to the Internet, you give away a variety of information: your PC’s IP address, some browser settings like language or screen size, and, probably, your login information. So how private is private? You might argue that your current IP address has been picked from a pool of addresses and therefore regularly changes, so it does not necessarily always pinpoint you. On the other hand, with the dawn of IPv6 there is no need any more for shared IP addresses as the...

  15. Complete Bipartite Anonymity for Location Privacy

    Users are vulnerable to privacy risks when providing their location information to location-based services (LBS). Existing work sacrifices the quality of LBS by degrading spatial and temporal accuracy for ensuring user privacy. In this paper, we propose a novel approach, Complete Bipartite Anonymity (CBA), aiming to achieve both user privacy and quality of service. The theoretical basis of CBA is that: if the bipartite graph of k nearby users’ paths can be transformed into a complete bipartite graph, then these users achieve k-anonymity since the set of “end points connecting to a specific start point in a graph”is an equivalence class. To achieve CBA, we design a Collaborative Path Confusion (CPC) protocol which enables nearby users to discover and authenticate each other without knowing their real identities or accurate locations, predict the encounter location using users’ moving pattern information, and generate fake traces obfuscating the real ones. We evaluate CBA using a real-world dataset, and compare its privacy performance with existing path confusion approach. The results show that CBA enhances location privacy by increasing the chance for a user confusing his/her path with others by 4 to 16 times in low user density areas. We also demonstrate that CBA is secure under the trace identification attack.

Data mining techniques are employed to ensure the privacy. Privacy Preserving Data Mining (PPDM techniques aim at protecting the sensitive data and mining results. In this study, the different Clustering techniques via classification with and without anonymization data using mining tool WEKA is presented. The aim of this study is to investigate the performance of different clustering methods for the diabetic data set and to compare the efficiency of privacy preserving mining. The accuracy of classification via clustering is evaluated using K-means, Expectation-Maximization (EM and Density based clustering methods.

  1. Gregory Bateson, Alcoholics Anonymous, and stoicism.

    Brundage, V

    1985-02-01

    In 1971 Gregory Bateson put forward an "entirely new epistemology," or view of the world, that he described as cybernetic. In a very influential article, which appeared in this journal, Bateson claimed that his cybernetic epistemology "coincides closely" with the epistemology of Alcoholics Anonymous (AA), for which he claimed "the only outstanding record of success" in the treatment of alcoholism (1971, p. 310). However, Bateson's discussion of AA dealt with only four of the Twelve Steps of AA's program. Although the epistemology of cybernetics and AA congrue in some respects, they contradict each other in many others. Common ground is found in the ancient philosophical tradition of Stoicism. In Stoicism the contradictions between the two are sources for an ethics and psychology of great power. Stoicism offers the cybernetic epistemologist a solid base for theory. It offers the clinician who deals with chemical dependency practical insights into the process of recovery.

  2. Comments on “Anonymous reviewers” [“Anonymous reviews: Self-serving, counterproductive, and unacceptable”

    Robinove, Charles J.

    Mryl Beck's Forum article denouncing anonymous reviews (Eos, 1 July 2003) is right on the money. Perhaps he read my letter in Applied Physics in 1990 also denouncing anonymous reviews.Some years ago, I received an anonymous review of a paper I had submitted for journal publication. The reviewer raised such interesting questions that I wanted to discuss them with him. I phoned the editor of the journal and asked if he would tell me the name of the reviewer. He politely declined, but when I told him I thought I recognized the handwriting of the reviewer and named him, he relented and said I was correct! I called the reviewer and he was generous enough to spend a wonderful hour on the phone with me discussing the paper. The paper was published with great consideration given to his ideas, much to its betterment. Now that's a reviewer whose interest is in improving the paper and helping the author, not just showing how smart he is or slapping down a junior colleague. The AGU motto,“unselfish cooperation in research,” can be well exemplified by those who wish to help rather than to tear down.

  3. P-Sensitive K-Anonymity with Generalization Constraints

    2010-08-01

    Full Text Available Numerous privacy models based on the k-anonymity property and extending the k-anonymity model have been introduced in the last few years in data privacy research: l-diversity, p-sensitive k-anonymity, (a, k anonymity, t-closeness, etc. While differing in their methods and quality of their results, they all focus first on masking the data, and then protecting the quality of the data as a whole. We consider a new approach, where requirements on the amount of distortion allowed on the initial data are imposed in order to preserve its usefulness. Our approach consists of specifying quasiidentifiers' generalization constraints, and achieving p-sensitive k-anonymity within the imposed constraints. We think that limiting the amount of allowed generalization when masking microdata is indispensable for real life datasets and applications. In this paper, the constrained p-sensitive k-anonymity model is introduced and an algorithm for generating constrained p-sensitive k-anonymous microdata is presented. Our experiments have shown that the proposed algorithm is comparable with existing algorithms used for generating p-sensitive k-anonymity with respect to the results' quality, and obviously the obtained masked microdata complies with the generalization constraints as indicated by the user.

    Objective We sought to identify factors influencing a woman's decision to have an elective repeat cesarean delivery (ERCD) versus vaginal birth after cesarean (VBAC). Methods and Materials A prospective study at two academic medical centers of women with one prior cesarean, and no contraindication to a trial of labor, delivered by ERCD from October 2013 to June 2014. Participants completed anonymous surveys during their delivery hospitalization. Counseling was considered adequate if women reported being counseled, recalled being quoted a VBAC success probability, and this probability was within 20% of that derived from an established VBAC success prediction model. Participants were also asked why they chose ERCD. Results Of 68 participants, only 8 (11.8%) had adequate counseling. Of those with inadequate counseling, 21.7% did not recall being counseled, 63.3% were not quoted a chance of success, and 60.0% had more than a 20% discrepancy between their recalled and predicted success rates. Eighteen women were calculated to have more than 70% chance of successful VBAC. Of these, 16 (88.9%) were not adequately counseled. Conclusion Most women were inadequately counseled about delivery options. The most important factors influencing the choice of ERCD over VBAC were patient preferences, risk for fetal injury, and perceived physician preference. PMID:27308098

  5. On the Utility of Anonymized Flow Traces for Anomaly Detection

    Burkhart, Martin; May, Martin

    2008-01-01

    The sharing of network traces is an important prerequisite for the development and evaluation of efficient anomaly detection mechanisms. Unfortunately, privacy concerns and data protection laws prevent network operators from sharing these data. Anonymization is a promising solution in this context; however, it is unclear if the sanitization of data preserves the traffic characteristics or introduces artifacts that may falsify traffic analysis results. In this paper, we examine the utility of anonymized flow traces for anomaly detection. We quantitatively evaluate the impact of IP address anonymization, namely variations of permutation and truncation, on the detectability of large-scale anomalies. Specifically, we analyze three weeks of un-sampled and non-anonymized network traces from a medium-sized backbone network. We find that all anonymization techniques, except prefix-preserving permutation, degrade the utility of data for anomaly detection. We show that the degree of degradation depends to a large exten...

  6. Improving Security Architecture of Anonymous Wireless Mesh Networks

    2012-01-01

    As users of networks increasingly aware of their privacy needs, the importance of anonymity is gaining popularity. The reason behind it is that anonymity can hide the actual identity of end users while allowing their to access services of network or web site. More over they are allowed to do so...... without being traced. This usage is prevailing in P2P systems and also payment based networks like e-cash. Achieving anonymity and being able to trace misbehaving users are the two conflicting requirements. This paper proposes a security architecture that is aimed at providing complete anonymity to honest...... users while tracing misbehaving users thus resolving the conflict between anonymity and traceability requirements. In addition to these, this paper also focuses on basic security requirements such as nonrepudiation, data integrity, confidentiality, and authentication. The empirical results revealed that...

    2013-05-01

    Full Text Available Anonymity, the stealth mode of public communication, challenges different actors who deal with freedom of communication issues in their day to day life – be it professional journalists, information and communication scientists, technicians or political activists. This article aims to deliver theoretical background on the concept of anonymity on the macro-level, as well as to shed light on how different communicators deal with anonymity on the micro-level. Based on the example of the Anonymous movement, communicative actions are put in relation to media technological artifacts and their surrounding media environment with a focus on journalistic practice and public response to the phenomenon. The analysis concludes with the need for a preservation of options for anonymous public communication as a dimension of freedom of communication after carefully considering both the advantages and the potential risks connected to that mode of private-public communication.

    2007-01-01

    In an anonymous secret sharing scheme the secret can be reconstructed without knowledge of which participants hold which shares. In this paper some constructions of anonymous secret sharing schemes with 2 thresholds by using combinatorial designs are given. Let υ(t, ω, q) denote the minimum size of the set of shares of a perfect anonymous (t, ω) threshold secret sharing scheme with q secrets. In this paper we prove that υ(t, ω, q) = Θ(q) if t and ω are fixed and that the lower bound of the size of the set of shares in [4] is not optimal under certain condition.

    E-cash is a type of very important electronic payment systems. The complete anonymity of E-cash can be used for criminal activities, so E-cash should be anonymity controlled.Moreover, Elliptic Curve Cryptography(ECC) has been regard as the mainstream of current public cryptography . In this paper, a new anonymity controlled E-cash scheme based on ECC for the first time and using a new technology-one-time key pairs digital signature is designed, and its security and efficiency are analyzed. In our scheme, the coin tracing and owner tracing can be implemented.

    Once limited to rare mendelian disorders, genetic counseling is playing an ever-increasing role in the multidisciplinary approach to predicting, diagnosing, and managing neurologic disease. However, genetic counseling services may not be optimized because of lack of availability and lack of knowledge regarding when it is appropriate to refer, what occurs in genetic counseling, and how genetic counseling can affect care. These issues are addressed in this article, along with corresponding clinical scenarios. Websites to find genetic counseling services and resources are also provided.

    2007-01-01

    A new architecture for scalable anonymous communication system(SACS) was proposed. The users were divided into several subgroups managed by different sub-blenders, and all sub-blenders were managed by the main-blender using two layers management scheme. The identity information of members are distributed on different sub-blenders, which makes each member keep much less information and network overload greatly reduce. The anonymity and the overhead of the new scheme were analyzed and compared with that of Crowds, which shows the cost of storage and network overhead for the new scheme largely decreases while the anonymity is little degraded. The experiment results also show that the new system architecture is well scalable. The ratio of management cost of SACS to that of Crowds is about 1:25 while the value of P(I|H1+) only increases by 0.001-0.020, which shows that SACS keeps almost the same anonymity with Crowds.

    2011-01-01

    The use of e-Auction services has been increasing in recent years. Security requirements in conducting e-Auctions are mainly bid privacy, anonymity and public verifiability. Most of the secure protocols concentrate on privacy and anonymity, which are achieved through bidder-resolved multi-party computation, assuming two or more trusted third parties, either through numerous auctioneers or with asymmetric models in which the commercial entity of an auction issuer or registration manager is assumed in addition to the auctioneer. Multi-attribute reverse auctions promise higher market efficiency and effective information exchange. This work extends and uses the existing schemes. This scheme uses scoring function, winner determination in multi-attribute auctions to implement public verifiability. Anonymity is achieved through bidder side pseudonym generation. By results and analysis we say this is very simple and effective scheme. This scheme ensures public verifiability and anonymity in multi-attribute auctions w...

  17. Theoretical Results on De-Anonymization via Linkage Attacks

    Directory of Open Access Journals (Sweden)

    Martin M. Merener

    2012-08-01

    Full Text Available Consider a database D with records containing history of individuals' transactions, that has been de-identified, i.e., the variables that uniquely associate records with individuals have been removed from the data. An adversary de-anonymizes D via a linkage attack if using some auxiliary information about a certain individual in the database, it can determine which record of D corresponds to such individual. One example of this is given in the article Robust De-anonymization of Large Sparse Datasets, by Narayanan and Shmatikov [19], which shows that an anonymized database containing records with ratings of different movies rented by customers of Netflix, could in fact be de-anonymized using very little auxiliary information, even with errors. Besides the heuristic de-anonymization of the Netflix database, Narayanan and Shmatikov provide interesting theoretical results about database de-anonymization that an adversary can produce under general conditions. In this article we revisit these theoretical results, and work them further. Our first contribution is to exhibit different simple cases in which the algorithm Scoreboard, meant to produce the theoretical de-anonymization in [19], fails to do so. By requiring 1-sim to be a pseudo-metric, and that the algorithm producing the de-anonymization outputs a record with minimum support among the candidates, we obtain and prove deanonymization results similar to those described in [19]. We then consider a new hypothesis, motivated by the fact (observed in heuristic de-anonymizations that when the auxiliary information contains values corresponding to rare attributes, the de-anonymization achieved is stronger. We formalize this using the notion on long tail [4], and give new theorems expressing the level of de-anonymization in terms of the parameters of the tail of the database D. The improvement in the deanonymization is reflected in the fact that when at least one value in the auxiliary information

  19. On the Feasibility of (Practical Commercial Anonymous Cloud Storage

    Directory of Open Access Journals (Sweden)

    Tobias Pulls

    2015-08-01

    Full Text Available Current de facto standard payment and billing models for commercial cloud storage services provide a plethora of information to the cloud provider about its clients. This leads to a hostile environment when seen from a privacy perspective. Motivated by recently leaked facts about large scale governmental surveillance efforts as well as the lack of privacy-preserving measures in existing commercial cloud storage services, in this paper, we investigate the feasibility of so called anonymous cloud storage services which require user payment (which we call commercial anonymous cloud storage. Anonymity in this context can be seen as the absence of information to uniquely identify a provider's client that is storing and manipulating data at the provider while at the same time still allowing fair billing, for both, the clients and the cloud provider. Although encrypting data prior to outsourcing helps to protect data privacy and can be achieved without the cloud provider's consent, the issues we are interested in, do not seem to be achievable that easily. However, while various measures for the latter issue, i.e., realizing access privacy, have been studied in the past, the role of privacy in context of billing and payment for cloud storage has, until now, remained unexplored. We therefore introduce an abstract model for commercial cloud storage services to define various types of anonymous cloud storage, study several payment and billing models for cloud storage services and their impact on the anonymity of the service's clients. Moreover, we discuss several solutions to provide anonymity within the different models. Our findings highlight the importance of anonymous payment for the practical deployment of commercial privacy-friendly cloud storage services. Furthermore, we provide directions for future work in some settings, i.e., when anonymous payment is not available, as interesting open challenges.

    2008-06-01

    This short survey of UK infertility counsellors was designed to determine whether the removal of donor anonymity resulted in noticeable changes in prospective parents' stated intentions regarding disclosure of their origins to any children conceived through donor conception. Members of the British Infertility Counselling Association working in Human Fertilisation and Embryology Authority (HFEA) -- licensed centres, before and after the legal changes, were sent a short questionnaire that included space for free comments (take-up: 62%). Three-quarters reported changes. Of these, two-thirds said prospective parents were more likely to say they would disclose, while less than a tenth said prospective parents were less likely do so. Where no changes were noted, this was primarily because the majority of prospective parents had stated their intention to be open even prior to the legal changes. Possible influences on intentions included: the culture within the centre, moves towards openness within the wider society, and parents' lack of confidence regarding how to go about disclosure. Follow-up studies are needed to improve understanding of whether influences on decision making carry through to patterns of actual disclosure; whether involvement in counselling affects outcomes; and whether access to professional assistance at the time of planned disclosure is helpful.

  3. Towards a respondent-preferred ki-anonymity model

    2015-01-01

    Recently, privacy concerns about data collection have received an increasing amount of attention. In data collection process, a data collector (an agency) assumed that all respondents would be comfortable with submitting their data if the published data was anonymous. We believe that this assumption is not realistic because the increase in privacy concerns causes some re-spondents to refuse participation or to submit inaccurate data to such agencies. If respondents submit inaccurate data, then the usefulness of the results from analysis of the collected data cannot be guaranteed. Furthermore, we note that the level of anonymity (i.e., k-anonymity) guaranteed by an agency cannot be verified by respondents since they generally do not have access to all of the data that is released. Therefore, we introduce the notion of ki-anonymity, where ki is the level of anonymity preferred by each respondent i. Instead of placing full trust in an agency, our solution increases respondent confidence by allowing each to decide the preferred level of protection. As such, our protocol ensures that respondents achieve their preferred ki-anonymity during data collection and guarantees that the collected records are genuine and useful for data analysis.

  7. Does anonymity increase the reporting of mental health symptoms?

    2012-09-01

    Full Text Available Abstract Background There is no doubt that the perceived stigma of having a mental disorder acts as a barrier to help seeking. It is possible that personnel may be reluctant to admit to symptoms suggestive of poor mental health when such data can be linked to them, even if their personal details are only used to help them access further care. This may be particularly relevant because individuals who have a mental health problem are more likely to experience barriers to care and hold stigmatizing beliefs. If that is the case, then mental health screening programmers may not be effective in detecting those most in need of care. We aimed to compare mental health symptom reporting when using an anonymous versus identifiable questionnaire among UK military personnel on deployment in Iraq. Methods Survey among UK military personnel using two questionnaires, one was anonymous (n = 315 and one collected contact details (i.e. identifiable, n = 296. Distribution was by alternate allocation. Data were collected in Iraq during January-February 2009. Results No significant difference in the reporting of symptoms of common mental disorders was found (18.1% of identifiable vs. 22.9% of anonymous participants. UK military personnel were more likely to report sub-threshold and probable PTSD when completing questionnaires anonymously (sub-threshold PTSD: 2.4% of identifiable vs. 5.8% of anonymous participants; probable PTSD: 1.7% of identifiable vs. 4.8% of anonymous participants. Of the 11 barriers to care and perceived social stigma statements considered, those completing the anonymous questionnaire compared to those completing the identifiable questionnaire were more likely to endorse three statements: “leaders discourage the use of mental health services” (9.3% vs. 4.6%, “it would be too embarrassing” (41.6% vs. 32.5% and “I would be seen as weak” (46.6% vs. 34.2%.

    Discuss the problem of infinite increasing coin list in anonymous E-cash systems, which reduce the efficiency of whole system greatly. Though some methods are suggested, no one can solve the problem with high efficiency and flexibility. Here, we use the technique of adding information in blind signatures to deal with this problem. Through adding timestamp in signatures, we can separate the valid period of all used coins into pieces. Only the coins in the last stage are recorded. So the scale of the coins list is controlled. We also analyze the anonymity of these data, and add some indispensable restrictions to them. These restrictions can ensure that the imported data don't break the anonymity of the customers. In order to fulfill these qualifications, we lead to the concept of restricted common data (RCD). Furthermore, we propose two schemes to add RCD in the blind signature. The simple one is easy to implement, while the complex one can note the value of the coin. The usage of RCD leads to little additional cost, as well as maintaining the anonymity of customers. This method fits for most kinds of anonymous E-cash systems.

  9. Persona: Network Layer Anonymity and Accountability for Next Generation Internet

    Science.gov (United States)

    Mallios, Yannis; Modi, Sudeep; Agarwala, Aditya; Johns, Christina

    Individual privacy has become a major concern, due to the intrusive nature of the services and websites that collect increasing amounts of private information. One of the notions that can lead towards privacy protection is that of anonymity. Unfortunately, anonymity can also be maliciously exploited by attackers to hide their actions and identity. Thus some sort of accountability is also required. The current Internet has failed to provide both properties, as anonymity techniques are difficult to fully deploy and thus are easily attacked, while the Internet provides limited level of accountability. The Next Generation Internet (NGI) provides us with the opportunity to examine how these conflicting properties could be efficiently applied and thus protect users’ privacy while holding malicious users accountable. In this paper we present the design of a scheme, called Persona that can provide anonymity and accountability in the network layer of NGI. More specifically, our design requirements are to combine these two conflicting desires in a stateless manner within routers. Persona allows users to choose different levels of anonymity, while it allows the discovery of malicious nodes.

    2014-12-01

    Anonymous pastoral care is one of the options for help in problems pertaining to sexuality. This paper explores the topics they seek help for, the religious aspects involved, and the relation between the normativity of their church tradition on the one hand and sexual and spiritual health criteria on the other. We analyzed helpseeking questions of two protestant Christian organizations in the Netherlands providing anonymous pastoral care: Refoweb and EO-Nazorg. Sexual themes were addressed in 19 and 2.3 % of the submitted questions, respectively. Of the helpseekers, 56 % is female, 15 % male, and 29 % unknown. Questions and problems for which people seek anonymous pastoral care focus primarily on premarital abstinence, gender roles, contraception, sexual orientation and masturbation. The authority of the Bible seems to be important for questioners, especially when dealing with ethical questions. Different relations between the normativity of the church tradition and sexual and spiritual health are discussed. PMID:23784431

    2013-05-01

    Full Text Available The Bitcoin network of decentralized payment transactions has attracted a lot of attention from both Internet users and researchers in recent years. Bitcoin utilizes a peer-to-peer network to issue anonymous payment transactions between different users. In the currently used Bitcoin clients, the full transaction history is available at each node of the network to prevent double spending without the need for a central authority, forming a valuable source for empirical research on network structure, network dynamics, and the implied anonymity challenges, as well as guidance on the future evolution of complex payment systems. We found dynamical effects of which some increase anonymity while others decrease it. Most importantly, several parameters of the Bitcoin transaction graph seem to have become stationary over the last 12–18 months. We discuss the implications.

  12. Anonymous Authorship Control for User-Generated Content

    Directory of Open Access Journals (Sweden)

    Suk-Bong LEE

    2007-12-01

    Full Text Available User-Generated Content (UGC is opening up new large market in content services, and more and more people are visiting web sites to share and enjoy UGCs. These trends make many authors to move into online. Authors want to conserve their authorship and expect to publish their UGC anonymously in cases. To meet the requirements, we propose a new authorship control model based on watermarking and metadata. Authors can embed their authorship into their UGC with identities or with anonym. Even though an author publishes his UGC anonymously, he can prove his authorship without unveiling his identity via 5 methods utilizing the proposed authorship model. The proposed model and methods need no TTP and are robust even based on fragile underlying watermarking scheme.

  13. An Effective Clustering Approach to Web Query Log Anonymization

    CERN Document Server

    Fard, Amin Milani

    2010-01-01

    Web query log data contain information useful to research; however, release of such data can re-identify the search engine users issuing the queries. These privacy concerns go far beyond removing explicitly identifying information such as name and address, since non-identifying personal data can be combined with publicly available information to pinpoint to an individual. In this work we model web query logs as unstructured transaction data and present a novel transaction anonymization technique based on clustering and generalization techniques to achieve the k-anonymity privacy. We conduct extensive experiments on the AOL query log data. Our results show that this method results in a higher data utility compared to the state of-the-art transaction anonymization methods.

  14. Applying l-Diversity in anonymizing collaborative social network

    Prasad, Ajay; Mitra, A; Singh, Arjun; Gour, Deepak

    2010-01-01

    To date publish of a giant social network jointly from different parties is an easier collaborative approach. Agencies and researchers who collect such social network data often have a compelling interest in allowing others to analyze the data. In many cases the data describes relationships that are private and sharing the data in full can result in unacceptable disclosures. Thus, preserving privacy without revealing sensitive information in the social network is a serious concern. Recent developments for preserving privacy using anonymization techniques are focused on relational data only. Preserving privacy in social networks against neighborhood attacks is an initiation which uses the definition of privacy called k-anonymity. k-anonymous social network still may leak privacy under the cases of homogeneity and background knowledge attacks. To overcome, we find a place to use a new practical and efficient definition of privacy called ldiversity. In this paper, we take a step further on preserving privacy in ...

  15. Application of Steganography for Anonymity through the Internet

    CERN Document Server

    Bahi, Jacques M; Friot, Nicolas; Guyeux, Christophe

    2012-01-01

    In this paper, a novel steganographic scheme based on chaotic iterations is proposed. This research work takes place into the information hiding security framework. The applications for anonymity and privacy through the Internet are regarded too. To guarantee such an anonymity, it should be possible to set up a secret communication channel into a web page, being both secure and robust. To achieve this goal, we propose an information hiding scheme being stego-secure, which is the highest level of security in a well defined and studied category of attacks called "watermark-only attack". This category of attacks is the best context to study steganography-based anonymity through the Internet. The steganalysis of our steganographic process is also studied in order to show it security in a real test framework.

  16. Secure and Efficient Anonymous Authentication Scheme in Global Mobility Networks

    Jun-Sub Kim

    2013-01-01

    Full Text Available In 2012, Mun et al. pointed out that Wu et al.’s scheme failed to achieve user anonymity and perfect forward secrecy and disclosed the passwords of legitimate users. And they proposed a new enhancement for anonymous authentication scheme. However, their proposed scheme has vulnerabilities that are susceptible to replay attack and man-in-the-middle attack. It also incurs a high overhead in the database. In this paper, we examine the vulnerabilities in the existing schemes and the computational overhead incurred in the database. We then propose a secure and efficient anonymous authentication scheme for roaming service in global mobility network. Our proposed scheme is secure against various attacks, provides mutual authentication and session key establishment, and incurs less computational overhead in the database than Mun et al.'s scheme.

  17. On the Definitions of Anonymity for Ring Signatures

    Science.gov (United States)

    Ohkubo, Miyako; Abe, Masayuki

    This paper studies the relations among several definitions of anonymity for ring signature schemes in the same attack environment. It is shown that one intuitive and two technical definitions we consider are asymptotically equivalent, and the indistinguishability-based technical definition is the strongest, i. e., the most secure when achieved, when the exact reduction cost is taken into account. We then extend our result to the threshold case where a subset of members cooperate to create a signature. The threshold setting makes the notion of anonymity more complex and yields a greater variety of definitions. We explore several notions and observe certain relation does not seem hold unlike the simple single-signer case. Nevertheless, we see that an indistinguishability-based definition is the most favorable in the threshold case. We also study the notion of linkability and present a simple scheme that achieves both anonymity and linkability.

  18. Completely anonymous multi-recipient signcryption scheme with public verification.

    Directory of Open Access Journals (Sweden)

    Liaojun Pang

    Full Text Available Most of the existing multi-recipient signcryption schemes do not take the anonymity of recipients into consideration because the list of the identities of all recipients must be included in the ciphertext as a necessary element for decryption. Although the signer's anonymity has been taken into account in several alternative schemes, these schemes often suffer from the cross-comparison attack and joint conspiracy attack. That is to say, there are few schemes that can achieve complete anonymity for both the signer and the recipient. However, in many practical applications, such as network conference, both the signer's and the recipient's anonymity should be considered carefully. Motivated by these concerns, we propose a novel multi-recipient signcryption scheme with complete anonymity. The new scheme can achieve both the signer's and the recipient's anonymity at the same time. Each recipient can easily judge whether the received ciphertext is from an authorized source, but cannot determine the real identity of the sender, and at the same time, each participant can easily check decryption permission, but cannot determine the identity of any other recipient. The scheme also provides a public verification method which enables anyone to publicly verify the validity of the ciphertext. Analyses show that the proposed scheme is more efficient in terms of computation complexity and ciphertext length and possesses more advantages than existing schemes, which makes it suitable for practical applications. The proposed scheme could be used for network conferences, paid-TV or DVD broadcasting applications to solve the secure communication problem without violating the privacy of each participant.

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    To provide mutual authentication among users, wireless networks, and service providers in roaming wireless environments, this article presents an anonymous authentication and access control protocol. Bases on this protocol, entities of different trusted domains can mutually authenticate each other and preserve the anonymity of users. Hybrid cryptosystem, secret splitting, and hash chains are used in the protocol, which decrease computational loads and establish trusted relations for both entities. The proposed protocol has the least computation complexity compared with other protocols, whereas, the security has been significantly improved.

    Full Text Available BACKGROUND: Clients of sex workers represent a relevant target for interventions aimed at the prevention of HIV and sexually transmitted infections (STIs. Within prevention strategies, the AIDS and sexually transmitted infections helpline (Telefono Verde AIDS/ IST, TVA-IST of National Institute of Health in Italy has provided, since 1987, specific information and counselling interventions. AIM: The present study reports data on anagraphical characteristics and behaviours of clients of sex workers, anonymously reported at TVA-IST in the period 1987-2010. DISCUSSION: Among 95 149 phone calls (14% of the total considered 99.5% came from males, over 80% aged under 37 years and prevalently from Northern Italy. Among sexual behaviours, unprotected sexual intercourses were reported in the 26% of the calls. Subjects under 27 years reported a higher frequency of unprotected anal intercourse, while they used protection with oral and vaginal intercourses in a greater extent than older ones. Due to differential behaviours within clients of sex workers, specific informative strategies for this targeted population should adequately consider age-related differences.

    2013-12-01

    International exchange training in genetic counseling is increasing, but research examining these experiences is lacking. In this study 309 genetic counseling students and genetic counselors completed an anonymous survey investigating six major research questions: (1) How prevalent are international genetic counseling experiences? (2) What types are pursued and why? (3) What supports and barriers exist? 3) What are the demographic characteristics of individuals accruing international experience? (5) Does international experience promote professional development? and (6) Do genetic counseling students and professionals perceive international experiences as beneficial? Most respondents were Caucasian females born in one of 25 countries. The most prevalent experiences involved either clinical observation or clinical training. Common motivations for pursuing international experience were personal growth, exposure to a different healthcare system, and travel opportunities. Outcomes included professionally-relevant experience and personal growth. Barriers included finances, limited availability of opportunities, and for those without international experience, family responsibilities. Additional findings, practice and training implications, and research recommendations are provided. PMID:23423708

    Full Text Available Role play activities provide opportunities for learners to adopt unfamiliar roles, engage in interactions with others, and get involved in realistic tasks. They are often recommended to foster the development of soft skills and a wider perspective of the world. Such activities are widely used as an online teaching approach, with examples ranging from the simple use of email to the employment of virtual worlds and Web 2.0 technologies.This paper provides a case study of a role play activity which employs real-time anonymous discussion forums and aims to improve our understanding of effective role play and the impact of anonymity. This role play has been effective in educating learners about different perspectives on the issue of Quality in Further Education. The context and implementation of the role play are outlined, and the learners’ interactions and experiences are explored using an investigative analysis of discussion transcripts and semi-structured interviews with participants. The findings suggest that role engagement and anonymity are important components for success in synchronous online role play. Evidence is presented that provides an insight into the factors which encourage role engagement, including prior experiences and contributions from peers. The impact of anonymity is also explored since many participants did not regard the study environment as real and attempted to identify their peers.

  17. A Generic Framework for Anonymous Authentication in Mobile Networks

    2013-01-01

    Designing an anonymous user authentication scheme in global mobility networks is a non-trivial task because wireless networks are susceptible to attacks and mobile devices powered by batteries have limited communication,processing and storage capabilities.In this paper,we present a generic construction that converts any existing secure password authentication scheme based on a smart card into an anonymous authentication scheme for roaming services.The security proof of our construction can be derived from the underlying password authentication scheme employing the same assumptions.Compared with the original password authentication scheme,the transformed scheme does not sacrifice the authentication efficiency,and additionally,an agreed session key can be securely established between an anonymous mobile user and the foreign agent in charge of the network being visited.Furthermore,we present an instantiation of the proposed generic construction.The performance analysis shows that compared with other related anonymous authentication schemes,our instantiation is more efficient.

  18. A reciprocal framework for spatial K-anonymity

    KAUST Repository

    Ghinita, Gabriel

    2010-05-01

    Spatial K-anonymity (SKA) exploits the concept of K-anonymity in order to protect the identity of users from location-based attacks. The main idea of SKA is to replace the exact location of a user U with an anonymizing spatial region (ASR) that contains at least K-1 other users, so that an attacker can pinpoint U with probability at most 1/K. Simply generating an ASR that includes K users does not guarantee SKA. Previous work defined the reciprocity property as a sufficient condition for SKA. However, the only existing reciprocal method, Hilbert Cloak, relies on a specialized data structure. In contrast, we propose a general framework for implementing reciprocal algorithms using any existing spatial index on the user locations. We discuss ASR construction methods with different tradeoffs on effectiveness (i.e., ASR size) and efficiency (i.e., construction cost). Then, we present case studies of applying our framework on top of two popular spatial indices (namely, R*-trees and Quad-trees). Finally, we consider the case where the attacker knows the query patterns of each user. The experimental results verify that our methods outperform Hilbert Cloak. Moreover, since we employ general-purpose spatial indices, the proposed system is not limited to anonymization, but supports conventional spatial queries as well. © 2009 Elsevier B.V.

    Holmes, Dave; O'Byrne, Patrick; Murray, Stuart J

    2010-10-01

    According to our previous research, the use of glory holes in public venues such as saunas and bathhouses is very popular. The popularity of glory holes is due in part to the anonymous sex that these architectural elements allow. This post-structuralist theoretical reflection seeks to understand the specific nature of anonymous public sex among bathhouse patrons, focusing on the links between desire-architecture-place-sexual practices. Drawing on interviews with glory hole users gathered during an ethnographic research project in bathhouses, this essay goes beyond traditional public health discourse to offer an original perspective on anonymous public sex. Utilizing the philosophy of Deleuze and Guattari's concepts of assemblages and machines, we re-theorize glory hole sex--what we call 'faceless sex'--and rethink the ways that desire is imbricated with our understanding of architecture, place, and public. Finally, we reflect upon the particular ethical challenges that are posed by these particular sexual practices, and ask whether a post-structuralist ethic might be possible. PMID:20840136

    2014-07-01

    Little attention has been given to whether adolescents' beliefs about anonymity and their normative beliefs about cyber aggression jointly increase their perpetration of cyber aggression. To this end, the present longitudinal study examined the moderating influence of these variables on the relationships among adolescents' attitudes toward the permanency of digital content, confidence with not getting caught, and anonymous cyber aggression (ACA) assessed 1 year later (Time 2). These associations were examined among 274 7th and 8th graders and through five technologies, including social networking sites (SNS), e-mail, instant messenger (IM), mobile phones, and chatrooms. Findings indicated that increases in Time 2 ACA and attitudes toward the permanency of digital content were more strongly related when adolescents reported greater confidence with not getting caught and higher normative beliefs concerning cyber aggression through SNS and mobile phones. In addition, higher levels of attitudes toward the permanency of digital content, confidence with not getting caught, beliefs about anonymity, and normative beliefs regarding cyber aggression were related to greater Time 2 ACA through e-mail, IM, and chatrooms. All findings are discussed in the context of adolescents' positive attitudes toward ACA, and an appeal for additional research is made to understand more about anonymity in cyberspace.

    Genetic counselling and testing for females with a family history of haemophilia has long been advocated. However, there is little research in regard to clients\\' satisfaction with the existing counselling models in haemophilia, and in particular with nurse-led clinics. The purpose of this study was to evaluate whether clients were satisfied with a nurse-led carrier testing clinic and counselling service. A retrospective quantitative study of clients\\' satisfaction and perceived knowledge was undertaken using an anonymous questionnaire. A sample of 42 women who had attended the clinic in the last 12 months was identified. The response rate for the study was 71% (n = 30).Two thirds of the respondents were 35 years of age or younger, 93% had a family history of haemophilia and 56% were diagnosed as carriers. Perceived understanding and knowledge increased significantly between the first and second appointments (p < 0.001). Overall, the study identified a high level of client satisfaction with the nurse-led carrier testing clinic and counselling service.

    Background:Human immunodeficiency virus (HIV) is spreading rapidly among men who have sex with men (MSM) in China.Anonymous questionnaires or direct interviews have been frequently used to study their behavior.The aim of the study was to describe the behavioral risk profile of the MSM in Beijing using the randomized response techniques (RRTs).Methods:A cross-sectional survey of sexual behavior among a sample of MSM was conducted in two HIV counseling and testing clinics in Beijing.The survey was carried out with an anonymous questionnaire containing sensitive questions on sexual behavior.To obtain the honest responses to the sensitive questions,three distinctive RRTs were used in the questionnaire:(1) Additive randomized response model for quantitative questions,(2) randomized response model for multiple choice questions,and (3) Simmons randomized response model for binomial questions.Formulae for the point estimate,variance,and confidence interval (CI) were provided for each specific model.Results:Using RRTs in a sample of 659 participants,the mean age at first homosexual encounter was estimated to be 21.7 years (95% CI:21.2-22.2),and each had sex with about three (2.9,95% CI:2.4-3.4) male partners on average in the past month.The estimated rate for consistent condom use was 56.4% (95% CI:50.1-62.8%).In addition,condom was estimated to be used among 80.0% (95% CI:74.1-85.9%) of the population during last anal sex with a male partner.Conclusions:Our study employed RRTs in a survey containing questions on sexual behavior among MSM,and the results showed that RRT might be a useful tool to obtain truthful feedback on sensitive information such as sexual behavior from the respondents,especially in traditional Chinese cultural settings.

    Free and anonymous screening centres (CDAG: Centres de Depistage Anononyme et Gratuit) are public facilities set up for HIV infection diagnosis in France. Some people visiting CDAG fail to return for test results and are not informed of their serology. This study aimed to assess factors associated with failure to return for HIV test results. Patients visiting the Fernand-Widal CDAG (Paris) for an HIV test in January-February 2011 were eligible to take part in the study. Data were collected with an anonymous self-administered questionnaire. Factors associated with failure to return were assessed using logistic regression models. Of the 710 participants (participation rate 88%), 46 patients failed to return. Not specifying birthplace and not living in the region of Paris were associated with failure to return. Those who perceived no risk of HIV infection and those who felt they were more at risk than other people were both statistically associated with failure to return. Self-perceived risk seemed to be of chief concern for failure to return for HIV test results and should be considered during pre-test counselling.

  14. Anonymous Card Shuffling and its Applications to Parallel Mixnets

    Goodrich, Michael T

    2012-01-01

    We study the question of how to shuffle $n$ cards when faced with an opponent who knows the initial position of all the cards {\\em and} can track every card when permuted, {\\em except} when one takes $K< n$ cards at a time and shuffles them in a private buffer "behind your back," which we call {\\em buffer shuffling}. The problem arises naturally in the context of parallel mixnet servers as well as other security applications. Our analysis is based on related analyses of load-balancing processes. We include extensions to variations that involve corrupted servers and adversarially injected messages, which correspond to an opponent who can peek at some shuffles in the buffer and who can mark some number of the cards. In addition, our analysis makes novel use of a sum-of-squares metric for anonymity, which leads to improved performance bounds for parallel mixnets and can also be used to bound well-known existing anonymity measures.

    We investigate the design of anonymous voting protocols, CV-based binary-valued ballot and CV-based multi-valued ballot with continuous variables (CV) in a multi-dimensional quantum cryptosystem to ensure the security of voting procedure and data privacy. The quantum entangled states are employed in the continuous variable quantum system to carry the voting information and assist information transmission, which takes the advantage of the GHZ-like states in terms of improving the utilization of quantum states by decreasing the number of required quantum states. It provides a potential approach to achieve the efficient quantum anonymous voting with high transmission security, especially in large-scale votes.

    2016-06-01

    A new experimentally feasible anonymous survey protocol with authentication using Greenberger-Horne-Zeilinger (GHZ) entangled states is proposed. In this protocol, a chief executive officer (CEO) of a firm or company is trying to find out the effect of a possible action. In order to prepare a fair voting, the CEO would like to make an anonymous survey and is also interested in the total action for the whole company and he doesn't want to have a partial estimate for each department. In our proposal, there are two voters, Alice and Bob, voting on a question with a response of either "yes" or "no" and a tallyman, whose responsibility is to determine whether they have cast the same vote or not. In the proposed protocol the total response of the voters is calculated without revealing the actual votes of the voters.

    Privacy of users in P2P networks goes far beyond their current usage and is a fundamental requirement to the adoption of P2P protocols for legal usage. In a climate of cold war between these users and anti-piracy groups, more and more users are moving to anonymizing networks in an attempt to hide their identity. However, when not designed to protect users information, a P2P protocol would leak information that may compromise the identity of its users. In this paper, we first present three attacks targeting BitTorrent users on top of Tor that reveal their real IP addresses. In a second step, we analyze the Tor usage by BitTorrent users and compare it to its usage outside of Tor. Finally, we depict the risks induced by this de-anonymization and show that users' privacy violation goes beyond BitTorrent traffic and contaminates other protocols such as HTTP.

    A major problem of mobile agents is their apparent inability to authenticate transactions in hostile environments. In this paper, a new secure anonymous mobile agent scheme is proposed for the prevention of agent tempering without compromising the mobility or autonomy of the agent. In the scheme, a mobile agent can produce valid signature on website's bid (it means to transact a contact with the web site) on behalf of its customer, without revealing the customer's real private key. In addition, the anonymity of the customer is also achieved when its agent transacts with the websites. Furthermore, the customer who issues a malicious agent or denies the transaction can be identified and detected by Agent Management Center (AMC). Therefore, the scheme is practical in the future electronic commerce over Internet.

    Growing demand for and limited geographic access to genetic counseling services is increasing the need for alternative service delivery models (SDM) like telephone genetic counseling (TGC). Little research has been done on genetic counselors' perspectives of the practice of TGC. We created an anonymous online survey to assess whether telephone genetic counselors believed the tasks identified in the ABGC (American Board of Genetic Counseling) Practice Analysis were performed similarly or differently in TGC compared to in person genetic counseling (IPGC). If there were differences noted, we sought to determine the nature of the differences and if additional training might be needed to address them. Eighty eight genetic counselors with experience in TGC completed some or all of the survey. Respondents identified differences in 13 (14.8%) of the 88 tasks studied. The tasks identified as most different in TGC were: "establishing rapport through verbal and nonverbal interactions" (60.2%; 50/83 respondents identified the task as different), "recognizing factors affecting the counseling interaction" (47.8%; 32/67), "assessing client/family emotions, support, etc." (40.1%; 27/66) and "educating clients about basic genetic concepts" (35.6%; 26/73). A slight majority (53.8%; 35/65) felt additional training was needed to communicate information without visual aids and more effectively perform psychosocial assessments. In summary, although a majority of genetic counseling tasks are performed similarly between TGC and IPGC, TGC counselors recognize that specific training in the TGC model may be needed to address the key differences.

    We consider small-influence anonymous games with a large number of players $n$ where every player has two actions. For this class of games we present a best-reply dynamic with the following two properties. First, the dynamic reaches Nash approximate equilibria fast (in at most $cn\\ log n$ steps for some constant $c>0$). Second, Nash approximate equilibria are played by the dynamic with a limit frequency of at least $1-e^{-c'n}$ for some constant $c'>0$.

    2012-01-01

    Full Text Available Problem statement: Ad hoc networks are susceptible to malicious attacks through denial of services, traffic analysis and spoofing. The security of the ad hoc routing protocol depends upon encryption, authentication, anonymity and trust factors. End-to-end security of data is provided by encryption and authentication, topology information of the nodes can be obtained by studying traffic and routing data. This security problem of ad hoc network is addressed by the use of anonymity mechanisms and trust levels. Identification information like traffic flow, network topology, paths from malicious attackers is hidden in anonymous networks. Similarly, trust plays a very important role in the intermediate node selection in ad hoc networks. Trust is essential as selfish and malicious nodes not only pose a security issue but also decreases the Quality of Service. Approach: In this study, a routing to address anonymous routing with a trust which improves the overall security of the ad hoc network was proposed. A new approach for an on demand ad-hoc routing algorithm, which was based on swarm intelligence. Ant colony algorithms were a subset of swarm intelligence and considered the ability of simple ants to solve complex problems by cooperation. The interesting point was, that the ants do not need any direct communication for the solution process, instead they communicate by stigmergy. The notion of stigmergy means the indirect communication of individuals through modifying their environment. Several algorithms which were based on ant colony problems were introduced in recent years to solve different problems, e.g., optimization problems. Results and Conclusion: It is observed that the overall security in the network improves when the trust factor is considered. It is seen that non performing nodes are not considered due to the proposed ACO technique.

    As a significant part of the Internet of Things (IoT), Wireless Body Area Network (WBAN) has attract much attention in this years. In WBANs, sensors placed in or around the human body collect the sensitive data of the body and transmit it through an open wireless channel in which the messages may be intercepted, modified, etc. Recently, Wang et al. presented a new anonymous authentication scheme for WBANs and claimed that their scheme can solve the security problems in the previous schemes. Unfortunately, we demonstrate that their scheme cannot withstand impersonation attack. Either an adversary or a malicious legal client could impersonate another legal client to the application provider. In this paper, we give the detailed weakness analysis of Wang et al.'s scheme at first. Then we present a novel anonymous authentication scheme for WBANs and prove that it's secure under a random oracle model. At last, we demonstrate that our presented anonymous authentication scheme for WBANs is more suitable for practical application than Wang et al.'s scheme due to better security and performance. Compared with Wang et al.'s scheme, the computation cost of our scheme in WBANs has reduced by about 31.58%.

    2015-09-01

    Full Text Available In Cloud computing, anonymous authentication is an important service that must be available to users in the Cloud. Users have the right to remain anonymous as long as they behave honestly. However, in case a malicious behavior is detected, the system – under court order – must be able to trace the user to his clear identity. Most of the proposed authentication schemes for the Cloud are either password-based authentication schemes that are vulnerable to offline dictionary attacks, or biometric-based authentication schemes that take a long time of execution specially in case of high security requirements. In this paper, we propose an efficient and secure scheme to non-interactively authenticate the users on the Cloud to the remote servers while preserving their anonymity. In case of accusations, the registration authority is able to trace any user to his clear identity. We avoid using low entropy passwords or biometric mechanisms, instead, we employ pseudonym systems in our design. The computation complexity and storage requirements are efficient and suitable to be implemented on smart cards/devices. Our proposed scheme withstands challenging adversarial attacks such as, stolen databases attacks, databases insertion attacks, impersonation attacks, replay attacks and malicious users/servers collaboration attacks.

    Full Text Available There are many proposals offer anonymous and non-repudiation e-payment protocols. But they have the drawbacks that the anonymity can be misused by fraudulent to perform a perfect crimes. Currently, the hot research concentrates on the accepting of e-payment protocols where the anonymity of the coins is cancelable via a trusted authority in the case of criminal entities. In the article we suggest an efficient protocol for e-payment scheme that offers a good level of security with appreciate to its efficiency. The proposed protocol prevents the blind office and the bank from impersonate an entity, so that the entity could not repudiate it when the entity misused a coin. Another benefit is that it is constructed from efficient cryptography schemes so that its security can simply be analyzed. The strength of this scheme is in its easiness. So, we claim that the suggested protocol is more efficient than the existing schemes, since it allows to both a blind office and a bank to impersonate an entity to find and to spend a coin without to be noticed. It might cause a repudiation difficulty where the entity can repudiate his bad activities by proposing that both the bank and the blind office acted inaccurately. Other relevant issues related to the new protocol will be discussed in the section of the security of the scheme.

    2013-01-01

    The Medical Research Involving Human Subjects Act (WMO) requires that participants in medical-scientific studies provide written consent. This requirement makes e-research (online research) unnecessarily difficult and sometimes impossible. Much of e-research involves online interventions that focus on sensitive issues such as sexual dysfunction, addiction and child abuse, for which anonymity is an important condition. WMO procedures, however, strictly interpret the word "written" as "on paper", and participants are not permitted to give consent by email, for example. A second requirement, which mainly makes studies among minors between the ages of 12 and 18 more difficult, is that both parents or the guardian must provide written consent. This undermines anonymity to such an extent that virtually no subjects remain. Participants in medical-scientific studies must always be identifiable to the investigator. But, apart from this, he/she should be possible to guarantee anonymity within the regulatory framework. There is good reason to adapt legal regulations to today's needs. PMID:24345359

    2012-04-01

    Full Text Available Digital Imaging and Communications in Medicine (DICOM is a standard for handling, storing, printing, and transmitting information in medical images. The DICOM file contains the image data and a number of attributes such as identified patient data (name, age, insurance ID card,…, and non-identified patient data (doctor’s interpretation, image type,…. Medical images serve not only for examination, but can also be used for research and education purposes. For research they are used to prevent illegal use of information; before authorizing researchers to use these images, the medical staff deletes all the data which would reveal the patient identity to prevent patient privacy. This manipulation is called anonymization. In this paper, we propose a reversible anonymization of DICOM images. Identifying patient data with image digest, computed by the well-known SHA-256 hash function, are encrypted using the proposed probabilistic public key crypto-system. After compressing the Least Significant Bit (LSB bitplan of the image using Hofmann coding algorithm, the encrypted data is inserted into a liberated zone of the LSB bitplan of the image. The proposed method allows researchers to use anonymous DICOM images and keep to authorized staff -if necessary- the possibility to return to the original image with all related patient data.

    2012-04-01

    Full Text Available Transaction data about individuals are increasingly collected to support a plethora of applications, spanning from marketing to biomedical studies. Publishing these data is required by many organizations, but may result in privacy breaches, if an attacker exploits potentially identifying information to link individuals to their records in the published data. Algorithms that prevent this threat by transforming transaction data prior to their release have been proposed recently, but they may incur significant utility loss due to their inability to: (i accommodate a range of different privacy requirements that data owners often have, and (ii guarantee that the produced data will satisfy data owners’ utility requirements. To address this issue, we propose a novel clustering-based framework to anonymizing transaction data, which provides the basis for designing algorithms that better preserve data utility. Based on this framework, we develop two anonymization algorithms which explore a larger solution space than existing methods and can satisfy a wide range of privacy requirements. Additionally, the second algorithm allows the specification and enforcement of utility requirements, thereby ensuring that the anonymized data remain useful in intended tasks. Experiments with both benchmark and real medical datasets verify that our algorithms significantly outperform the current state-of-the-art algorithms in terms of data utility, while being comparable in terms of efficiency.

  18. An Analysis of Anonymity in the Bitcoin System

    CERN Document Server

    Reid, Fergal

    2011-01-01

    Anonymity in Bitcoin, a peer-to-peer electronic currency system, is a complicated issue. Within the system, users are identified by public-keys only. An attacker wishing to de-anonymize its users will attempt to construct the oneto- many mapping between users and public-keys and associate information external to the system with the users. Bitcoin frustrates this attack by storing the mapping of a user to his or her public-keys on that user's node only and by allowing each user to generate as many public-keys as required. In this paper we consider the topological structure of two networks derived from Bitcoin's public transaction history. We show that the two networks have a non-trivial topological structure, provide complementary views of the Bitcoin system and have implications for anonymity. We combine these structures with external information and techniques such as context discovery and flow analysis to investigate an alleged theft of Bitcoins, which, at the time of the theft, had a market value of approx...

    Bettini, C.; Wang, X S; S. Jajodia

    2006-01-01

    The concept of k-anonymity, used in the recent literature to formally evaluate the privacy preservation of published tables, was introduced based on the notion of quasi-identifiers (or QI for short). The process of obtaining k-anonymity for a given private table is first to recognize the QIs in the table, and then to anonymize the QI values, the latter being called k-anonymization. While k-anonymization is usually rigorously validated by the authors, the definition of QI remains mostly inform...

    In this article we provide a formal framework for reidentification in general. We define n-confusion as a concept for modelling the anonymity of a database table and we prove that n-confusion is a generalization of k- anonymity. After a short survey on the different available definitions of k- anonymity for graphs we provide a new definition for k-anonymous graph, which we consider to be the correct definition. We provide a description of the k-anonymous graphs, both for the regular and the n...

    Intimate ties and emotional relationship gain the function to confirm, to stabilize and, afterwards, to structure the coherency's model of the structured self-organization up to that moment. When the couple perceives the bond of the relationship such as a sole and exclusive for a person, they take a leading role to be able to deduce a sense of individuality and uniqueness in the way to feel himself in the world. Based on these considerations, in this paper I propose a brief description of a counselling method, which characterises the work I am carrying out since several years in the counselling and therapy with couples.

  11. The implications of stigma and anonymity for self-disclosure in health blogs.

    Rains, Stephen A

    2014-01-01

    The reported study examines the implications of anonymity and stigma in the form of illness-related embarrassment for self-disclosure in the context of health blogging. Drawing from theorizing about anonymous communication and stigma, anonymity is argued to be strategically used by individuals who are embarrassed by their illness and to moderate the relationship between embarrassment and self-disclosure. Data from 114 individuals who blog about their experiences coping with a health condition were examined to test study hypotheses. Illness-related embarrassment was positively associated with anonymity. Additionally, anonymity moderated the relationship between embarrassment and self-disclosure. Among bloggers with relatively higher levels of anonymity, illness-related embarrassment was positively associated with self-disclosure. The results suggest that anonymity is strategically used and fosters self-disclosure among individuals who are embarrassed by their illness.

  20. Quantum election scheme based on anonymous quantum key distribution

    International Nuclear Information System (INIS)

    An unconditionally secure authority-certified anonymous quantum key distribution scheme using conjugate coding is presented, based on which we construct a quantum election scheme without the help of an entanglement state. We show that this election scheme ensures the completeness, soundness, privacy, eligibility, unreusability, fairness, and verifiability of a large-scale election in which the administrator and counter are semi-honest. This election scheme can work even if there exist loss and errors in quantum channels. In addition, any irregularity in this scheme is sensible. (general)

    Full Text Available Business Information Exchange is an Internet Secure Portal for secure management, distribution, sharing, and use of business e-mails, documents, and messages. It has three applications supporting three major types of information exchange systems: secure e-mail, secure instant messaging, and secure sharing of business documents. In addition to standard security services for e-mail letters, which are also applied to instant messages and documents, the system provides innovative features of privacy and full anonymity of users and their locations, actions, transactions, and exchanged resources. In this paper we describe design, implementation, and use of the system.

    We propose a model for deterministic distributed function computation by a network of identical and anonymous nodes, with bounded computation and storage capabilities that do not scale with the network size. Our goal is to characterize the class of functions that can be computed within this model. In our main result, we exhibit a class of non-computable functions, and prove that every function outside this class can at least be approximated. The problem of computing averages in a distributed manner plays a central role in our development.

  5. Osteopathic medical student administered smoking cessation counseling is an effective tool

    Directory of Open Access Journals (Sweden)

    Barbara Capozzi

    2016-01-01

    Full Text Available Background: Physician counseling on the risks of tobacco smoking and the benefits of cessation has been shown to be an effective method of increasing the rate of smoking cessation. Using the "Help Your Patients Quit Smoking: A Coaching Guide" also referred to as the "7A′s of Smoking Cessation" guideline from the New York City Department of Health and Mental Hygiene is thought to be effective to convey the importance of smoking cessation. Aim: To study the efficacy of the "7A′s of Smoking Cessation" guideline counseling conducted by osteopathic medical students. Materials and Methods: Osteopathic medical students were trained to counsel smokers for 3-10 min based on New York City Department of Health′s "7A′s of Smoking Cessation" guidelines by a licensed physician. Students then counseled health fair participants who were cigarette smokers for 3-10 min. Postcounseling, participants were administered an 4 question survey to evaluate the effect counseling had on their desire to quit smoking. Survey data were collected and analyzed. Institutional Review Board approval was obtained for this study. Results: A total of 13 anonymous health fair participants who were also smokers were administered both counseling sessions and surveys. 11/13 (84.6% participants stated that the session motivated them to quit smoking. 9/13 (69.2% participants responded that they were now motivated to discuss smoking cessation with their doctor after being counseled. Of these participants 12/13 (92.3% had previously attempted to quit smoking without success. Conclusion: Participants reported an increased willingness to stop smoking after being counseled by osteopathic medical students. Participants also reported an increased motivation to discuss smoking cessation with their physician. These findings indicate that smoking cessation counseling administered by osteopathic medical students effectively in encouraging smokers to consider reduction or cessation of tobacco

  6. The end of donor anonymity: how genetic testing is likely to drive anonymous gamete donation out of business.

    Harper, Joyce C; Kennett, Debbie; Reisel, Dan

    2016-06-01

    Thousands of people worldwide have been conceived using donor gametes, but not all parents tell their children of their origin. Several countries now allow donor-conceived offspring to potentially know their genetic parent if they are informed of their donor-conceived status. At the same time, personal genetic testing is a rapidly expanding field. Over 3 million people have already used direct-to-consumer genetic testing to find information about their ancestry, and many are participating in international genetic genealogy databases that will match them with relatives. The increased prevalence of these technologies poses numerous challenges to the current practice of gamete donation. (i) Whether they are donating in a country that practices anonymous donation or not, donors should be informed that their anonymity is not guaranteed, as they may be traced if their DNA, or that of a relative, is added to a database. (ii) Donor-conceived adults who have not been informed of their status may find out that they are donor-conceived. (iii) Parents using donor conception need to be fully informed that their children's DNA will identify that they are not the biological parents and they should be encouraged to disclose the use of donor gametes to their children. Together, these concerns make urgent a wide-ranging societal conversation about how to best safeguard and promote the interests of donor-conceived offspring and protect the rights of donors. Specifically, there is a need to ensure that new genetic information is communicated in a way that promotes both the safety and the privacy rights of offspring and donors alike. All parties concerned must be aware that, in 2016, donor anonymity does not exist. PMID:27073260

  7. Applying Stylometric Analysis Techniques to Counter Anonymity in Cyberspace

    Full Text Available Due to the ubiquitous nature and anonymity abuses in cyberspace, it’s difficult to make criminal identity tracing in cybercrime investigation. Writeprint identification offers a valuable tool to counter anonymity by applying stylometric analysis technique to help identify individuals based on textual traces. In this study, a framework for online writeprint identification is proposed. Variable length character n-gram is used to represent the author’s writing style. The technique of IG seeded GA based feature selection for Ensemble (IGAE is also developed to build an identification model based on individual author level features. Several specific components for dealing with the individual feature set are integrated to improve the performance. The proposed feature and technique are evaluated on a real world data set encompassing reviews posted by 50 Amazon customers. The experimental results show the effectiveness of the proposed framework, with accuracy over 94% for 20 authors and over 80% for 50 ones. Compared with the baseline technique (Support Vector Machine, a higher performance is achieved by using IGAE, resulting in a 2% and 8% improvement over SVM for 20 and 50 authors respectively. Moreover, it has been shown that IGAE is more scalable in terms of the number of authors, than author group level based methods.

  8. Quantum anonymous voting with unweighted continuous-variable graph states

    Guo, Ying; Feng, Yanyan; Zeng, Guihua

    2016-08-01

    Motivated by the revealing topological structures of continuous-variable graph state (CVGS), we investigate the design of quantum voting scheme, which has serious advantages over the conventional ones in terms of efficiency and graphicness. Three phases are included, i.e., the preparing phase, the voting phase and the counting phase, together with three parties, i.e., the voters, the tallyman and the ballot agency. Two major voting operations are performed on the yielded CVGS in the voting process, namely the local rotation transformation and the displacement operation. The voting information is carried by the CVGS established before hand, whose persistent entanglement is deployed to keep the privacy of votes and the anonymity of legal voters. For practical applications, two CVGS-based quantum ballots, i.e., comparative ballot and anonymous survey, are specially designed, followed by the extended ballot schemes for the binary-valued and multi-valued ballots under some constraints for the voting design. Security is ensured by entanglement of the CVGS, the voting operations and the laws of quantum mechanics. The proposed schemes can be implemented using the standard off-the-shelf components when compared to discrete-variable quantum voting schemes attributing to the characteristics of the CV-based quantum cryptography.

    2010-01-01

    An online buyer of multimedia content does not want to reveal his identity or his choice of multimedia content whereas the seller or owner of the content does not want the buyer to further distribute the content illegally. To address these issues we present a new private anonymous fingerprinting protocol. It is based on superposed sending for communication security, group signature for anonymity and traceability and single database private information retrieval (PIR) to allow the user to get an element of the database without giving any information about the acquired element. In the presence of a semi-honest model, the protocol is implemented using a blind, wavelet based color image watermarking scheme. The main advantage of the proposed protocol is that both the user identity and the acquired database element are unknown to any third party and in the case of piracy, the pirate can be identified using the group signature scheme. The robustness of the watermarking scheme against Additive White Gaussian Noise is also shown.

    from applications when the smartphone is used under the anonymous modality. They are re-instated back when the smartphone returns to work in the normal modality. In addition, both solutions offer protection from applications that identify their users through traces left in the application's data storage or through exchanging identifying data messages. We developed IdentiDroid, a customized Android operating system, to deploy these solutions and built IdentiDroid Profile Manager, a profile-based configuration tool that allows one to set different configurations for each installed Android application. With this tool, applications running within the same device are configured to be given different identifications and privileges to limit the uniqueness of device and user information. We analyzed 250 Android applications to determine what information, services, and permissions can identify users and devices. Our experiments show that when IdentiDroid is deployed and properly configured on Android devices, users' anonymity is better guaranteed by either of the proposed solutions with no significant impact on most device applications.

  11. Keeping mum about dad: "contracts" to protect gamete donor anonymity.

    Science.gov (United States)

    Rees, Anne

    2012-06-01

    This article considers the legal status of so-called contracts for anonymity between fertility clinics and donors of gametes that were made in the period before legislation authorising disclosure. It notes that while clinics frequently cite the existence of these "contracts" to argue against retrospective legislation authorising disclosure of the donor's identity, they may be nothing more than one-sided statements of informed consent. However, the article notes that even if an agreement between a donor and a clinic is not contractual, it does not follow that a person conceived through assisted reproductive technology has any right of access to the identity of the donor. The writer has not been able to locate examples of written promises by the clinics promising anonymity. There are written promises by the donors not to seek the identity of the recipients. These promises do not bind the resulting offspring nor do they appear to be supported by consideration. The article suggests that the basis for any individual donor to restrain a clinic from revealing their identity may be found in promissory estoppel. Nevertheless, there is no real issue in Australia concerning clinics revealing these details absent legislative authority. The issue is whether parliaments will legislate to authorise the disclosure. The article notes that it would be rare for parliaments to legislate to overturn existing legal contracts but suggests that the contract argument may not be as strong as has been thought.

  14. Rett syndrome molecular diagnosis and implications in genetic counseling

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available Rett syndrome is a rare genetic X-linked dominant disorder. This syndrome is the most frequent cause of mental retardation in girls. In the classical form of the disease, the presenting signs and the course of development are characteristic. However clinical diagnosis can be very difficult when the expression is not in the classical form. Mutations in MeCP2 are responsible for 80% of cases. When MeCP2 mutation is found in an index case, genetic counseling is similar to that in other X-linked dominant genetic diseases. However, mutations in this gene can cause a spectrum of atypical forms. On the other hand, other genetic conditions like translocations, sex chromosome numerical anomalies, and mutations in other genes can complicate genetic counseling in this syndrome. We present the first case of molecular diagnosis of Rett syndrome in Iran and discuss the recent developments in its genetic counseling.

    Remote user authentication is essential in distributed network environment to protect unauthorized access of a networked system. However, most of those existing remote user authentication schemes have not provided the user identity anonymity, while user anonymity is particularly important in some practical applications.Therefore, based on self-encryption mechanism, a new remote user authentication scheme was proposed. The scheme not only has no need of maintaining a password table at the remote server, but also can protect the user's anonymity.

    Concerns that standard didactic adherence counselling may be inadequate to maximise antiretroviral therapy (ART) adherence led us to evaluate more intensive individualised motivational adherence counselling. We randomised 297 HIV-positive ART-naïve patients in Durban, South Africa, to receive either didactic counselling, prior to ART initiation (n = 150), or an intensive motivational adherence intervention after initiating ART (n = 147). Study arms were similar for age (mean 35.8 years), sex (43.1 % male), CD4+ cell count (median 121.5 cells/μl) and viral load (median 119,000 copies/ml). Virologic suppression at 9 months was achieved in 89.8 % of didactic and 87.9 % of motivational counselling participants (risk ratio [RR] 0.98, 95 % confidence interval [CI] 0.90-1.07, p = 0.62). 82.9 % of didactic and 79.5 % of motivational counselling participants achieved >95 % adherence by pill count at 6 months (RR 0.96, 95 % CI 0.85-1.09, p = 0.51). Participants receiving intensive motivational counselling did not achieve higher treatment adherence or virological suppression than those receiving routinely provided didactic adherence counselling. These data are reassuring that less resource intensive didactic counselling was adequate for excellent treatment outcomes in this setting.

This technology may also identify fetal sex and can be used to screen for sex chromosome aneuploidies (SCAs). Physicians offering this screening will need to be prepared to offer comprehensive prenatal counseling about these disorders to an increasing number of patients. The purpose of this article is to consider the source of information to use for counseling, factors in parental decision-making, and the performance characteristics of cfDNA testing in screening for SCAs. Discordance between ultrasound examination and cfDNA results regarding fetal sex is also discussed.

    2013-01-01

    Anonymization of Electronic Medical Records to Support Clinical Analysis closely examines the privacy threats that may arise from medical data sharing, and surveys the state-of-the-art methods developed to safeguard data against these threats. To motivate the need for computational methods, the book first explores the main challenges facing the privacy-protection of medical data using the existing policies, practices and regulations. Then, it takes an in-depth look at the popular computational privacy-preserving methods that have been developed for demographic, clinical and genomic data sharing, and closely analyzes the privacy principles behind these methods, as well as the optimization and algorithmic strategies that they employ. Finally, through a series of in-depth case studies that highlight data from the US Census as well as the Vanderbilt University Medical Center, the book outlines a new, innovative class of privacy-preserving methods designed to ensure the integrity of transferred medical data for su...

  3. ANDaNA: Anonymous Named Data Networking Application

    DiBenedetto, Steven; Tsudik, Gene; Uzun, Ersin

    2011-01-01

    Content-centric networking -- also known as information-centric networking (ICN) -- shifts emphasis from hosts and interfaces (as in today's Internet) to data. Named data becomes addressable and routable, while locations that currently store that data become irrelevant to applications. Named Data Networking (NDN) is a large collaborative research effort that exemplifies the content-centric approach to networking. NDN has some innate privacy-friendly features, such as lack of source and destination addresses on packets. However, as discussed in this paper, NDN architecture prompts some privacy concerns mainly stemming from the semantic richness of names. We examine privacy-relevant characteristics of NDN and present an initial attempt to achieve communication privacy. Specifically, we design an NDN add-on tool, called ANDaNA, that borrows a number of features from Tor. As we demonstrate via experiments, it provides comparable anonymity with lower relative overhead.

    2013-02-01

    While it is acknowledged that there is a need for more qualitative research on suicide, it is also clear that the ethics of undertaking such research need to be addressed. This article uses the case study of the authors' experience of gaining ethics approval for a research project that asks people what it is like to feel suicidal to (a) analyse the limits of confidentiality and anonymity and (b) consider the ways in which the process of ethics review can shape and constrain suicide research. This leads to a discussion of the ways in which ethics committees assess and monitor qualitative research more generally and some preliminary suggestions for how this might be improved.

    2014-01-01

    To respond to the need for new HIV prevention services for men who have sex with men (MSM) in the United States, and to respond to new data on the key role of main partnerships in US MSM epidemics, we sought to develop a new service for joint HIV testing of male couples. We used the ADAPT-ITT framework to guide our work. From May 2009 to July 2013, a multiphase process was undertaken to identify an appropriate service as the basis for adaptation, collect data to inform the adaptation, adapt the testing service, develop training materials, test the adapted service, and scale up and evaluate the initial version of the service. We chose to base our adaptation on an African couples HIV testing service that was developed in the 1980s and has been widely disseminated in low- and middle-income countries. Our adaptation was informed by qualitative data collections from MSM and HIV counselors, multiple online surveys of MSM, information gathering from key stakeholders, and theater testing of the adapted service with MSM and HIV counselors. Results of initial testing indicate that the adapted service is highly acceptable to MSM and to HIV counselors, that there are no evident harms (e.g., intimate partner violence, relationship dissolution) associated with the service, and that the service identifies a substantial number of HIV serodiscordant male couples. The story of the development and scale-up of the adapted service illustrates how multiple public and foundation funding sources can collaborate to bring a prevention adaptation from concept to public health application, touching on research, program evaluation, implementation science, and public health program delivery. The result of this process is an adapted couples HIV testing approach, with training materials and handoff from academic partners to public health for assessment of effectiveness and consideration of the potential benefits of implementation; further work is needed to optimally adapt the African couples

    Full Text Available Counselling should undergo a certain process to ensure that a counselling session would achieve its targeted goal. This article intends to analyze the understanding of Malaysian counsellors in light of the counselling process that they choose to conduct. To achieve this objective, six practising counsellors were chosen as participants for this research. Data collected through the methods of structured interviews using interview protocol which is thematically analysed by the NVivo 2 software. Results of the analysis showed that these counsellors understood the counselling process based on the theories that they were using. Besides, they followed several stages and levels in the counselling process with the awareness on the vital elements need to be considered in each process.

  14. The anonymity paradox in patient engagement: reputation, risk and web-based public feedback.

    Science.gov (United States)

    Speed, Ewen; Davison, Charlie; Gunnell, Caroline

    2016-06-01

    The UK National Health Service (NHS) has long espoused patient and public engagement. Recent years have seen increasing use of internet-based methods of collecting feedback about patient experience and public and staff views about NHS services and priorities. Often hailed as a means of facilitating participative democratic patient engagement, these processes raise a number of complex issues. A key aspect of it is the opportunity for comment to be made anonymously. Our research reveals an anonymity paradox whereby patients clearly demonstrate a perception that anonymity is a prerequisite for effective use of these feedback processes, whereas professionals demonstrate a perception that patient anonymity is a barrier to effective use. The risks of anonymity are constructed very differently by patients and professionals. Patient concerns around anonymity were not motivated by a general concern about a loss of privacy, but more that a positive identification might compromise future care. For professionals, concerns were voiced more around risks of reputational damage for specific practitioners or practices (in that anyone could say anything) and also that this anonymous feedback was available publicly and that it might go against the medical opinion of the professional. These concerns pointed to important differences in perceptions of patient and professional vulnerability. In the qualitative analysis that follows the key finding was that while anonymity makes service users feel less vulnerable, it can have the opposite effect on managers and clinical staff. This raises important implications for the use and utility of internet-based methods of collecting patient feedback.

  17. Anonimos: An LP based Approach for Anonymizing Weighted Social Network Graphs

    CERN Document Server

    Das, Sudipto; Abbadi, Amr El

    2010-01-01

    The increasing popularity of social networks has initiated a fertile research area in information extraction and data mining. Anonymization of these social graphs is important to facilitate publishing these data sets for analysis by external entities. Prior work has concentrated mostly on node identity anonymization and structural anonymization. But with the growing interest in analyzing social networks as a weighted network, edge weight anonymization is also gaining importance. We present An\\'onimos, a Linear Programming based technique for anonymization of edge weights that preserves linear properties of graphs. Such properties form the foundation of many important graph-theoretic algorithms such as shortest paths problem, k-nearest neighbors, minimum cost spanning tree, and maximizing information spread. As a proof of concept, we apply An\\'onimos to the shortest paths problem and its extensions, prove the correctness, analyze complexity, and experimentally evaluate it using real social network data sets.

  5. Breastfeeding counsel against cancers

    Prameela Kannan Kutty

    2016-01-01

    The anticancer potential by breastfeeding is not fully tapped in the light of the present knowledge of the subject. Literature indicates that breastmilk has anticancer action but may underestimate its full capacity. The protective spectrum within breastmilk hints on the need for a more comprehensive understanding of it as an anticancer tool. Exclusive breastfeeding could confer protection from carcinogenesis with a greater impact than realised. A literature review was conducted using four electronic databases. Selected areas were extracted after thorough perusal of the articles. The uninitiated would take exclusive breastfeeding seriously if actively counselled as an anticancer tool. Advice on details of the breastfeeding process and holistic information on breastfeeding may endow a greater impact among the skeptics. Counselling the breastfeeding mother on information sometimes not imparted, such as on maternal nutrition, details of the process of breast-feeding, benefits of direct breastfeeding versus milk expression and her psychosocial well being may make a difference in optimising anticancer action that exists in breastmilk. Additionally, its anticancer potential provides a platform to universally improve physical and psychosocial well being of women who breastfeed. Statistics of protection by breastfeeding in some maternal and childhood cancers are evident. “Bio-geno-immuno-nutrition” of breastmilk may shield the mother and infant from carcinogenesis in more ways than appreciated. The molecular basis of mother-to-infant signals and their “en-ergies” need to be researched. Breastfeeding as a modifiable behaviour provides cost effective nutrition with potential for both cancer immunoprophylaxis and immunotherapy.

    Full Text Available Objective. To examine the proportion of health care providers who counsel adolescent patients on sports and energy drink (SED consumption and the association with provider characteristics. Methods. This is a cross-sectional analysis of a survey of providers who see patients ≤17 years old. The proportion providing regular counseling on sports drinks (SDs, energy drinks (EDs, or both was assessed. Chi-square analyses examined differences in counseling based on provider characteristics. Multivariate logistic regression calculated adjusted odds ratios (aOR for characteristics independently associated with SED counseling. Results. Overall, 34% of health care providers regularly counseled on both SEDs, with 41% regularly counseling on SDs and 55% regularly counseling on EDs. On adjusted modeling regular SED counseling was associated with the female sex (aOR: 1.44 [95% CI: 1.07–1.93], high fruit/vegetable intake (aOR: 2.05 [95% CI: 1.54–2.73], family/general practitioners (aOR: 0.58 [95% CI: 0.41–0.82] and internists (aOR: 0.37 [95% CI: 0.20–0.70] versus pediatricians, and group versus individual practices (aOR: 0.59 [95% CI: 0.42–0.84]. Modeling for SD- and ED-specific counseling found similar associations with provider characteristics. Conclusion. The prevalence of regular SED counseling is low overall and varies. Provider education on the significance of SED counseling and consumption is important.

    The growth in smartphone market share has seen the increasing emergence of individuals collecting quantitative wellness data. Beyond the potential health benefits for the individual in regards to managing their own health, the data is highly related to preventative and risk factors for a number of lifestyle related diseases. This data has often been a component of public health data collection and epidemiological studies due to its large impact on the health system with chronic and lifestyle diseases increasingly being a major burden for the health service. However, collection of this kind of information from large segments of the community in a usable fashion has not been specifically explored in previous work. In this paper we discuss some of the technologies that increase the ease and capability of gathering quantitative wellness data via smartphones, how specific and detailed this data needs to be for public health use and the challenges of such anonymized data collection for public health. Additionally, we propose a conceptual architecture that includes the necessary components to support this approach to data collection. PMID:23366349

  9. Delineating social network data anonymization via random edge perturbation

    KAUST Repository

    Xue, Mingqiang

    2012-01-01

    Social network data analysis raises concerns about the privacy of related entities or individuals. To address this issue, organizations can publish data after simply replacing the identities of individuals with pseudonyms, leaving the overall structure of the social network unchanged. However, it has been shown that attacks based on structural identification (e.g., a walk-based attack) enable an adversary to re-identify selected individuals in an anonymized network. In this paper we explore the capacity of techniques based on random edge perturbation to thwart such attacks. We theoretically establish that any kind of structural identification attack can effectively be prevented using random edge perturbation and show that, surprisingly, important properties of the whole network, as well as of subgraphs thereof, can be accurately calculated and hence data analysis tasks performed on the perturbed data, given that the legitimate data recipient knows the perturbation probability as well. Yet we also examine ways to enhance the walk-based attack, proposing a variant we call probabilistic attack. Nevertheless, we demonstrate that such probabilistic attacks can also be prevented under sufficient perturbation. Eventually, we conduct a thorough theoretical study of the probability of success of any}structural attack as a function of the perturbation probability. Our analysis provides a powerful tool for delineating the identification risk of perturbed social network data; our extensive experiments with synthetic and real datasets confirm our expectations. © 2012 ACM.

  10. Parameterized Complexity of the k-anonymity Problem

    CERN Document Server

    Bonizzoni, Paola; Dondi, Riccardo; Pirola, Yuri

    2009-01-01

    The problem of publishing personal data without giving up privacy is becoming increasingly important. An interesting formalization that has been recently proposed is the $k$-anonymity. This approach requires that the rows of a table are partitioned in clusters of size at least $k$ and that all the rows in a cluster become the same tuple, after the suppression of some entries. The natural optimization problem, where the goal is to minimize the number of suppressed entries, is known to be APX-hard even when the records values are over a binary alphabet and $k=3$, and when the records have length at most 8 and $k=4$ . In this paper we study how the complexity of the problem is influenced by different parameters. In this paper we follow this direction of research, first showing that the problem is W[1]-hard when parameterized by the size of the solution (and the value $k$). Then we exhibit a fixed parameter algorithm, when the problem is parameterized by the size of the alphabet and the number of columns. Finally...

    The aims of this study are to assess the impact of Austria's anonymous birth law from the time relevant statistical records are available and to evaluate the use of hatches versus anonymous hospital delivery. This study is a complete census of police-reported neonaticides (1975-2012) as well as anonymous births including baby hatches in Austria during 2002-2012. The time trends of neonaticide rates, anonymous births and baby hatches were analysed by means of Poisson and logistic regression model. Predicted and observed rates were derived and compared using a Bayesian Poisson regression model. Predicted numbers of neonaticides for the period of the active awareness campaign, 2002-2004, were more than three times larger than the observed number (p = 0.0067). Of the 365 women who benefitted from this legislation, only 11.5% chose to put their babies in a baby hatch. Since the law was introduced, a significant decreasing tendency of numbers of anonymous births (p = 047) was observed, while there was significant increase of neonaticide rates (p = 0.0001). The implementation of the anonymous delivery law is associated with a decrease in the number of police-reported neonaticides. The subsequent significantly decreasing numbers of anonymous births with an accompanying increase of neonaticides represents additional evidence for the effectiveness of the measure. PMID:26267063

  14. FEATURES OF STUDENT PSYCHOLOGICAL COUNSELLING

    Directory of Open Access Journals (Sweden)

    Maria Dorina PASCA

    2013-10-01

    Full Text Available Student psychological counseling is one of the means to acknowledge student identity by employing counseling tools that allow the psychologist to make use of a set of skills essential in achieving envisaged outcomes. To act as counseling psychologist for students is to guide actions by the five wh- questions: who (the client is, why (the counselor is approached, who (the counselor talks to, what (problem the student has to tackle, how (the problem can be solved. Some of the most important features that contribute to solving student problems are the counselor’s deontology, trustworthiness and attitude that are to be relied on without impeding the client’s personality traits. Thus, developing awareness of the features underlying student psychological counseling and acting accordingly is the real test for any professional in the field. Therefore, the real challenge is not being in the lion’s den, but living with it.

    2014-01-01

    An anonymous authentication scheme for roaming services in global mobility networks allows a mobile user visiting a foreign network to achieve mutual authentication and session key establishment with the foreign-network operator in an anonymous manner. In this work, we revisit He et al.'s anonymous authentication scheme for roaming services and present previously unpublished security weaknesses in the scheme: (1) it fails to provide user anonymity against any third party as well as the foreign agent, (2) it cannot protect the passwords of mobile users due to its vulnerability to an offline dictionary attack, and (3) it does not achieve session-key security against a man-in-the-middle attack. We also show how the security weaknesses of He et al.'s scheme can be addressed without degrading the efficiency of the scheme. PMID:25302330

  18. Atomic and anonymous e-Cash transaction protocol with off-line TTP

    王茜; 李朝阳; 杨德礼

    2004-01-01

    Atomicity and anonymity are desirable properties for reliable and security e-Cash transaction and the guarantee of the participants' interests. But there are conflicts between these two properties. In this paper, an atomic and anonymous e-Cash transaction protocol with off-line TTP (Trust Third Party) based on the extended CEMBS is presented. The novel protocol is analyzed for its atomicity and anonymity. The results of the analysis show that it not only provides atomicity and anonymity under unreliable communication and dishonest partici-pants, but also features high efficiency and practicability. The new protocol also avoids transaction from a am-biguous state. Furthermore, it will be referenced often for the application of the atomic e-Cash transaction proto-col.

  19. The Role of the Anonymous Voice in Post-Publication Peer Review Versus Traditional Peer Review

    Directory of Open Access Journals (Sweden)

    Jaime A. Teixeira da Silva

    2015-12-01

    Full Text Available Traditional peer review (TPR has several limitations and weaknesses. Post-publication peer review is one practical way to repair the ills of TPR and reinforce it. A literature that is marked by errors is unhealthy and should, if given the opportunity, be corrected or further improved. The anonymous voice is one source of critique and differs from the blind peer review in TPR in which the reviewer remains anonymous to the authors and/or vice versa, but the identity is known to the editor. If unregulated, the anonymous voice can pose a threat to established editorial norms in TPR, to one of the most important criteria of science publishing, i.e., transparency, and to worthwhile discussion. Yet, if the anonymous voice is not heard, then a vast and potentially valuable pool of untapped opinions may be lost, opinions that may provide valuable solutions to improving TPR.

  3. Genetic Counseling Supervisors' Self-Efficacy for Select Clinical Supervision Competencies.

    Finley, Sabra Ledare; Veach, Pat McCarthy; MacFarlane, Ian M; LeRoy, Bonnie S; Callanan, Nancy

    2016-04-01

    Supervision is a primary instructional vehicle for genetic counseling student clinical training. Approximately two-thirds of genetic counselors report teaching and education roles, which include supervisory roles. Recently, Eubanks Higgins and colleagues published the first comprehensive list of empirically-derived genetic counseling supervisor competencies. Studies have yet to evaluate whether supervisors possess these competencies and whether their competencies differ as a function of experience. This study investigated three research questions: (1) What are genetic counselor supervisors' perceptions of their capabilities (self-efficacy) for a select group of supervisor competencies?, (2) Are there differences in self-efficacy as a function of their supervision experience or their genetic counseling experience, and 3) What training methods do they use and prefer to develop supervision skills? One-hundred thirty-one genetic counselor supervisors completed an anonymous online survey assessing demographics, self-efficacy (self-perceived capability) for 12 goal setting and 16 feedback competencies (Scale: 0-100), competencies that are personally challenging, and supervision training experiences and preferences (open-ended). A MANOVA revealed significant positive effects of supervision experience but not genetic counseling experience on participants' self-efficacy. Although mean self-efficacy ratings were high (>83.7), participant comments revealed several challenging competencies (e.g., incorporating student's report of feedback from previous supervisors into goal setting, and providing feedback about student behavior rather than personal traits). Commonly preferred supervision training methods included consultation with colleagues, peer discussion, and workshops/seminars.

  4. [Does really sex addiction exist?].

    Science.gov (United States)

    Echeburúa, Enrique

    2012-01-01

    Hypersexual Disorder has been proposed as a new psychiatric disorder for DSM-V, characterized by an increased frequency and intensity of sexually motivated fantasies, arousal, urges, and enacted behavior in association with an impulsivity component. Excessive appetitive and consummatory behaviors, including hypersexuality, can become a non-chemical addiction. Sexual addiction afflicts people having paraphilic or nonparaphilic behaviors associated with progressive risk-taking sexual behaviors, escalation or progression of sexual behaviors (tolerance), loss of control and significant adverse psychosocial consequences, such as unplanned pregnancy, pair-bond dysfunction, marital separation, financial problems and sexually transmitted diseases including HIV. The most common behaviors involved in sexual addiction are fantasy sex, compulsive masturbation, pornography, cybersex, voyeuristic sex, anonymous sex and multiple sexual partners. These behaviors are intended to reduce anxiety and other dysphoric affects (e.g., shame and depression). Axis I psychiatric diagnosis, especially mood disorders, psychoactive substance abuse disorders and attention deficit hyperactivity disorders, are common comorbid disorders with sexual addiction. There are significant gaps in the current scientific knowledge base regarding the clinical course, development risk factors and family history and data on women with sexual addiction are lacking.

  11. To Speak or Not to Speak: Developing Legal Standards for Anonymous Speech on the Internet

    Directory of Open Access Journals (Sweden)

    Tomas A. Lipinski

    2002-01-01

    Full Text Available This paper explores recent developments in the regulation of Internet speech, in specific, injurious or defamatory speech and the impact such speech has on the rights of anonymous speakers to remain anonymous as opposed to having their identity revealed to plaintiffs or other third parties. The paper proceeds in four sections.  First, a brief history of the legal attempts to regulate defamatory Internet speech in the United States is presented. As discussed below this regulation has altered the traditional legal paradigm of responsibility and as a result creates potential problems for the future of anonymous speech on the Internet.  As a result plaintiffs are no longer pursuing litigation against service providers but taking their dispute directly to the anonymous speaker. Second, several cases have arisen in the United States where plaintiffs have requested that the identity of an anonymous Internet speaker be revealed.  These cases are surveyed.  Third, the cases are analyzed in order to determine the factors that courts require to be present before the identity of an anonymous speaker will be revealed.  The release is typically accomplished by the enforcement of a discovery subpoena instigated by the party seeking the identity of the anonymous speaker. The factors courts have used are as follows: jurisdiction, good faith (both internal and external, necessity (basic and sometimes absolute, and at times proprietary interest. Finally, these factors are applied in three scenarios--e-commerce, education, and employment--to guide institutions when adopting policies that regulate when the identity of an anonymous speaker--a customer, a student or an employee--would be released as part of an internal initiative, but would nonetheless be consistent with developing legal standards.

  13. Verbal Venting in the Social Web: Effects of Anonymity and Group Norms on Aggressive Language Use in Online Comments

    Directory of Open Access Journals (Sweden)

    Leonie Rösner

    2016-08-01

    Full Text Available Scholars often blame the occurrence of aggressive behavior in online discussions on the anonymity of the Internet; however, even on today’s less anonymous platforms, such as social networking sites, users write plenty of aggressive comments, which can elicit a whole wave of negative remarks. Drawing on the social identity and deindividuation effects (SIDE model, this research conducts a laboratory experiment with a 2 (anonymity vs. no anonymity × 2 (aggressive norm vs. non-aggressive norm between-subjects design in order to disentangle the effects of anonymity, social group norms, and their interactions on aggressive language use in online comments. Results reveal that participants used more aggressive expressions in their comments when peer comments on a blog included aggressive wording (i.e., the social group norm was aggressive. Anonymity had no direct effect; however, we found a tendency that users’ conformity to an aggressive social norm of commenting is stronger in an anonymous environment.

  14. Link Prediction by De-anonymization: How We Won the Kaggle Social Network Challenge

    CERN Document Server

    Narayanan, Arvind; Rubinstein, Benjamin I P

    2011-01-01

    This paper describes the winning entry to the IJCNN 2011 Social Network Challenge run by Kaggle.com. The goal of the contest was to promote research on real-world link prediction, and the dataset was a graph obtained by crawling the popular Flickr social photo sharing website, with user identities scrubbed. By de-anonymizing much of the competition test set using our own Flickr crawl, we were able to effectively game the competition. Our attack represents a new application of de-anonymization to gaming machine learning contests, suggesting changes in how future competitions should be run. We introduce a new simulated annealing-based weighted graph matching algorithm for the seeding step of de-anonymization. We also show how to combine de-anonymization with link prediction---the latter is required to achieve good performance on the portion of the test set not de-anonymized---for example by training the predictor on the de-anonymized portion of the test set, and combining probabilistic predictions from de-anony...

  15. Serbs in the poetry of Theodore Prodromos and anonymous Manganeios

    Directory of Open Access Journals (Sweden)

    Stanković Vlada

    2006-01-01

    Full Text Available Numerous rhetorical writings of the Comnenian period constitute a fruitful field of research, both with respect to historical data, i.e. hard historical facts hidden, though still recognizable, behind the peculiar and somewhat abstract mode of expression of the authors of the twelfth century, and with regard to the poetics of the literary works themselves, i.e. the internal elements characteristic not only for the genre chosen, but also for each particular author. A comparative, historical and literary approach to these works renders their sense clearer and their complex allusions more readily understood. This is a matter of some importance, since allusions constitute one of the basic elements of historical rhetoric, which reached its peak at the time of Emperor Manuel Komnenos (1143-1180, especially during the first half of his reign, i.e. till the end of the fifties of the twelfth century. The poetry of Theodore Prodromes and of the somewhat younger Anonymous ('Prodromos' Manganeios is an excellent example of this intertwining of historical and literary elements, i.e. of the presentation of historical data through rhetorical patterns. One has to concentrate on individual works attempting to determine, as far as possible, the date of composition, the circumstances of writing and the purpose of a particular poem, the occasion for which it was written and the character of the expected audience, in order to better understand both the poetry written by these two rhetoricians and the individual features of the authors, as well as their respective positions in the circle around Emperor Manuel Komnenos. The poems dealt with in the present paper stand out for calling the Serbs by their real name. This naming practice was invariably employed by both rhetoricians in cases when new achievements of the basileus were to be announced and proclaimed immediately after the event, on the occasions of first reports, first celebrations of the new victories and

However, there are many security threats to mobile networks and their impact on security is more serious than that in wireline networks owing to the features of wireless transmissions and the ubiquity property. The secret information which mobile users carry may be stolen by malicious entities. To guarantee the quality of advanced services, security and privacy would be important issues when users roam within various mobile networks. In this manuscript, an anonymous authentication scheme will be proposed to protect the security of the network system and the privacy of users. Not only does the proposed scheme provide mutual authentication between each user and the system, but also each user’s identity is kept secret against anyone else, including the system. Although the system anonymously authenticates the users, it can still generate correct bills to charge these anonymous users via a credit-based solution instead of debit-based ones. Furthermore, our protocols also achieve fair privacy which allows the judge to revoke the anonymity and trace the illegal users when they have misused the anonymity property, for example, if they have committed crimes. Finally, in this paper, we also carry out complete theoretical proofs on each claimed security property.

    The rapid growing of online purchasing of information products poses challenges of how to preserve the customer's privacy during the online transactions. The current widely used way of online shopping does not consider the customer's privacy protection. It exposes the customer's sensitive information unnecessarily. We propose a new five-party implementation model called 5PAPS that provides much enhanced protection of the customer's privacy. The model combines the advantages of the e-cash techniques, the mix technique, the anonymous-honoring merchant model, and the anonymity-protecting payment gateway model. It is aimed for protecting the customer's anonymity in all applicable aspects. Security and anonymity issues of the model have been analyzed. The results show that the model is robust against varieties of common attacks and the customer's anonymity can be protected even in the presence of some collusion among the parties involved in the transactions. Experimental prototyping of the essential parts yields partial validation of the practical nature of the 5PAPS model, and it has also produced reliable estimates of the storage and messaging volume requirements present in sizable purchasing systems.

    Intellectual disability (ID) with or without other anomalies is a common referral for genetic counseling. Sessions may include discussions of reproductive implications and other issues related to sex education. Patients with ID regularly meet barriers when trying to obtain sex education due to the misperceptions of others as being either asexual or that such education would promote inappropriate sexual behavior. In this pilot study, we surveyed genetic counselors to explore their experiences with being asked to provide sex education counseling and their comfort in doing so for patients with ID ages 9-17. Results were analyzed from 38 respondents. Caregivers and patients most frequently requested information on puberty, sex abuse prevention, and reproductive health. Genetic counselors were most comfortable when they could provide sex education counseling within the context of a particular condition or constellation of features. They were least comfortable when they lacked familiarity with the patient, caregiver, or the family's culture. The most frequently cited barriers that prevented genetic counselors from providing sex education counseling were lack of time, lack of training, the patient's ID being too profound, and a belief that genetic counselors should not be responsible for providing sex education counseling. While many respondents reported that providing sex education counseling is not considered within the scope of a genetic counselor's practice, they also noted that patients' families initiate discussions for which counselors should be prepared. Respondents indicated that resource guides specifically designed for use by genetic counselors would be beneficial to their practice. Genetic counselors have the opportunity to embrace the role of advocate and broach the issue of sexual health with caregivers and patients by directing them toward educational resources, if not providing sex education directly to effectively serve the needs of patients and

  9. RSSI-Based User Centric Anonymization for Location Privacy in Vehicular Networks

    Science.gov (United States)

    Wei, Yu-Chih; Chen, Yi-Ming; Shan, Hwai-Ling

    In Vehicular Networks, for enhancing driving safety as well as supporting other applications, vehicles periodically broadcast safety messages with their precise position information to neighbors. However, these broadcast messages make it easy to track specific vehicles and will likely lead to compromise of personal privacy. Unfortunately, current location privacy enhancement methodologies in VANET, including Pseudonymization, K-anonymity, Random silent period, Mix-zones and path confusion, all suffer some shortcomings. In this paper, we propose a RSSI (Received Signal Strength Indicator)-based user centric anonymization model, which can significantly enhance the location privacy and at the same time ensure traffic safety. Simulations are performed to show the advantages of the proposed method. In comparison with traditional random silent period method, our method can increase at least 47% of anonymity in both simple and correlation tracking.

    2015-12-01

    Full Text Available Background: In order to provide appropriate advice to the patient at the time of dispensing and over-the-counter (OTC medication counseling, community pharmacists need access to current and reliable information about medicines. Brazilian pharmacists have assumed new functions such as prescribing medication, in a dependent model, based in protocols. Objective: To examine the practice of community pharmacists in a Brazilian State, focusing on OTC recommendation. Method: A cross-sectional survey of community pharmacists in a state of Brazil was conducted from October 2013 to January 2014, with data collection through a pre-piloted self-administered anonymous survey via Survey Monkey® platform. Following ethical approval, the online instrument was sent to 8,885 pharmacists registered in Parana State, Brazil, focusing on professionals working in community pharmacies. The questionnaire assessed the community pharmacy setting, the search for information, the knowledge of the evidence-based practice, the important factors to consider when recommending an OTC medicine, and the pharmacist prescribing. Responses were imported into SPSS® (version 22.0 for analysis. Nonparametric tests were used to assess the association between responses and demographic information with a significance level less than 5% (p<0.05. Results: Of the pharmacists, 97.4% dispensed medications and counseled patients for a median of six hours per day. Product's efficacy (97% and adverse effects (62.3% were the most important factors taken into account when counseling a nonprescription medicine. Few pharmacists knew the meaning of terms related to evidence-based health. Most respondents agreed that pharmacists have the necessary training to prescribe. Conclusion: Over-the-counter medication counseling is a daily practice among Brazilian pharmacists. Learning needs exist for community pharmacists in relation to evidence-based practice. Thus, sources of information with good evidence

A rapid result HIV testing for MSM through voluntary counselling and testing (VCT facility (“Checkpoint” was opened in Geneva in 2005. This gay-friendly facility, the first to open in Switzerland, provides testing for sexually transmitted infections (STI and rapid result HIV testing and counselling. Our objective was to analyze Checkpoint’s activity over its first five years of activity and its ability to attract at-risk MSM. Methods We used routine data collected anonymously about the facility activity (number of clients, number of tests, and test results and about the characteristics of the clientele (sociodemographic data, sexual risk behaviour, and reasons for testing from 2005 to 2009. Results The yearly number of HIV tests performed increased from 249 in 2005 to 561 in 2009. The annual proportion of positive tests among tests performed varied between 2% and 3%. Among MSM clients, the median annual number of anal intercourse (AI partners was three. Roughly 30% of all MSM clients had at least one unprotected anal intercourse (UAI experience in the previous 12 months with a partner of different/unknown HIV status. The main reason for testing in 2007, 2008, and 2009 was “sexual risk exposure” (~40%, followed by “routine” testing (~30% and “condom stopping in the beginning of a new steady relationship” (~10%. Clients who came to the facility after a sexual risk exposure, compared to clients who came for "routine testing" or "condom stopping" reasons, had the highest number of AI partners in the previous 12 months, were more likely to have had UAI with a partner of different/unknown HIV status in the previous 12 months (respectively 57.3%, 12.5%, 23.5%, more likely to have had an STI diagnosed in the past (41.6%, 32.2%, 22.9%, and more likely to report recent feelings of sadness or depression

  1. Source Anonymity in WSNs against Global Adversary Utilizing Low Transmission Rates with Delay Constraints.

    Science.gov (United States)

    Bushnag, Anas; Abuzneid, Abdelshakour; Mahmood, Ausif

    2016-01-01

    Wireless sensor networks (WSN) are deployed for many applications such as tracking and monitoring of endangered species, military applications, etc. which require anonymity of the origin, known as Source Location Privacy (SLP). The aim in SLP is to prevent unauthorized observers from tracing the source of a real event by analyzing the traffic in the network. Previous approaches to SLP such as Fortified Anonymous Communication Protocol (FACP) employ transmission of real or fake packets in every time slot, which is inefficient. To overcome this shortcoming, we developed three different techniques presented in this paper. Dummy Uniform Distribution (DUD), Dummy Adaptive Distribution (DAD) and Controlled Dummy Adaptive Distribution (CAD) were developed to overcome the anonymity problem against a global adversary (which has the capability of analyzing and monitoring the entire network). Most of the current techniques try to prevent the adversary from perceiving the location and time of the real event whereas our proposed techniques confuse the adversary about the existence of the real event by introducing low rate fake messages, which subsequently lead to location and time privacy. Simulation results demonstrate that the proposed techniques provide reasonable delivery ratio, delay, and overhead of a real event's packets while keeping a high level of anonymity. Three different analysis models are conducted to verify the performance of our techniques. A visualization of the simulation data is performed to confirm anonymity. Further, neural network models are developed to ensure that the introduced techniques preserve SLP. Finally, a steganography model based on probability is implemented to prove the anonymity of the techniques. PMID:27355948

Aiming at this problem, this paper defines anonymity by using the uncertainty of the voting choices and measures the anonymity of the whole voting system by entropy. It compares the anonymity after the release of the voting results with that before releasing the voting results. Analysis result shows that the smaller the voting scale is, the more the voters' anonymity loses. In the design of small-scale electronic-voting scheme, releasing the winner instead of the number of votes that candidates gained decreases the loss of anonymity.

  3. Recipient screening in IVF: First data from women undergoing anonymous oocyte donation in Dublin

    LENUS (Irish Health Repository)

    Walsh, Anthony PH

    2011-04-20

    Abstract Background Guidelines for safe gamete donation have emphasised donor screening, although none exist specifically for testing oocyte recipients. Pre-treatment assessment of anonymous donor oocyte IVF treatment in Ireland must comply with the European Union Tissues and Cells Directive (Directive 2004\\/23\\/EC). To determine the effectiveness of this Directive when applied to anonymous oocyte recipients in IVF, we reviewed data derived from selected screening tests performed in this clinical setting. Methods Data from tests conducted at baseline for all women enrolling as recipients (n = 225) in the anonymous oocyte donor IVF programme at an urban IVF referral centre during a 24-month period were analysed. Patient age at programme entry and clinical pregnancy rate were also tabulated. All recipients had at least one prior negative test for HIV, Hepatitis B\\/C, chlamydia, gonorrhoea and syphilis performed by her GP or other primary care provider before reproductive endocrinology consultation. Results Mean (±SD) age for donor egg IVF recipients was 40.7 ± 4.2 yrs. No baseline positive chlamydia, gonorrhoea or syphilis screening results were identified among recipients for anonymous oocyte donation IVF during the assessment interval. Mean pregnancy rate (per embryo transfer) in this group was 50.5%. Conclusion When tests for HIV, Hepatitis B\\/C, chlamydia, gonorrhoea and syphilis already have been confirmed to be negative before starting the anonymous donor oocyte IVF sequence, additional (repeat) testing on the recipient contributes no new clinical information that would influence treatment in this setting. Patient safety does not appear to be enhanced by application of Directive 2004\\/23\\/EC to recipients of anonymous donor oocyte IVF treatment. Given the absence of evidence to quantify risk, this practice is difficult to justify when applied to this low-risk population.

  4. The French bioethics public consultation and the anonymity doctrine: empirical ethics and normative assumptions.

    Science.gov (United States)

    Spranzi, Marta; Brunet, Laurence

    2015-03-01

    The French bioethics laws of 1994 contain the principles of the anonymity and non commodification of all donations of body parts and products including gametes in medically assisted reproduction. The two revisions of the law, in 2004 and 2011 have upheld the rule. In view of the latest revision process, the French government organized a large public consultation in 2009 ("Etats généraux de la bioéthique"). Within the event a "consensus conference" was held in Rennes about different aspects of assisted reproduction (access, anonymity, gratuity and surrogacy). In what follows we shall first describe the anonymity clause for gamete donations in the French law and the debates surrounding it. We shall then analyse the procedure used for the 2009 public consultation and the related consensus conference, as well as its upshot concerning the anonymity doctrine. In this respect we shall compare the citizens' own recommendations on the gamete anonymity issue and its translation in the consultation's final report drafted by a philosopher mandated by the organizing committee. Whereas the final report cited some fundamental ethical arguments as reason for upholding the provisions of the law-most notably the refusal of the 'all biological' approach to reproductive issues-citizens were more careful and tentative in their position although they also concluded that for pragmatic reasons the anonymity rule should continue to hold. We shall argue that the conservative upshot of the public consultation is due to some main underlying presuppositions concerning the citizens' role and expertise as well as to the specific design of the consensus conference. Our conclusion will be that public consultations and consensus conferences can only serve as an empirical support for devising suitable bioethics norms by using second-order normative assumptions.

    Full Text Available Aim: The purpose of this study was to compare the attention bias about tempting incentives related to opium materials in treated, addicted and normal people. Duration of consumption and treating were also considered. Method: In this causal-comparative study population was all addicted people who were referred to the rehabilitation offices, addiction treatment clinic, rebirthing centers and Narcotics Anonymous of East Azerbaijan. This study consisted of five groups of men, including addicted to opium materials which are divided into two groups namely: long consumption period and people with short consumption period, also, treated people including long term treated and short term treated, and a normal control group. Altogether, 103 selected people were studied. Sample groups were similar in terms of age, education, and sex. For measuring attention bias towards tempting stimuli related opiates, a words recognition test was used. This test included three subtests and one recognition test. The recognition scores for the three categories of words were measured. Results: The findings indicated that there was a difference in attention against opium material incentives between control group and the mild and severe consumers groups. Also there were significant differences between treated people with the short time distance and control group, and control group had less temptation and biases in comparison to the other groups. Finally, those who have mild consumption are threatened more in comparison with the control group. Conclusion: The findings have applied implications.

    In this paper, we propose an efficient authentication protocol with conditional privacy preservation for secure vehicular communications. The proposed protocol follows the system model to issue on-the-fly anonymous public key certificates to vehicles by road-side units. In order to design an efficient message authentication protocol, we consider a key-insulated signature scheme for certifying anonymous public keys of vehicles to such a system model. We demonstrate experimental results to confirm that the proposed protocol has better performance than other protocols based on group signature schemes.

    Pregnant women undergoing prenatal genetic testing should receive genetic counseling so they can make informed decisions. We examined the current state of providing genetic counseling in Japan to pregnant women before they elected amniocentesis for prenatal diagnosis of chromosome abnormalities and after test results were completed, and explored the opportunity for expanding access to certified genetic counselors (CGC) at clinical practices offering amniocentesis. An anonymous survey was mailed to the 298 hospitals that referred amniotic fluid specimens to LabCorp Japan in 2009. Most genetic counseling was provided by the obstetrician alone; 73.8 % (76/103) of pre-amniocentesis, 82.5 % (85/103) if normal results, and 49.4 % (44/89) if abnormal results. Respondents spent limited time in genetic counseling; 57.3 % spent role in clinical practice, responses that supported employment of CGC were more likely to come from hospitals that submitted more than ten specimens annually (p genetic counseling available in Japan. This indicates there are opportunities for the employment of CGC to improve the quality of genetic counseling.

    2011-03-01

    Asphyxiophilic sex is a form of autoerotic activity, in which the user creates mechanical means (such as hanging or bondage) in order to achieve cerebral hypoxia, which, in turn, enhances sexual, as well as orgasmic, stimulus. Failure of safety mechanisms, created by the user, may lead to instant death as a result of asphyxiation or strangulation. This kind of sexual practice is more prevalent among men than in women. In cases of death, it is difficult to relate it to the sexual practice itself. Suicide and homicide are the main differential diagnoses. Closely related derivatives of asphyxiophilic sex are anesthesiophilia (inhalation of variable volatile substances) and electrophilia (use of electric current during sexual activity)--both also intended to enhance the sexual stimulation. These forms of sexual practice are less prevalent than asphyxiophilia. PMID:21574359

  17. Anonymous Search Histories Featuring Personalized Advertisement - Balancing Privacy with Economic Interests

    Directory of Open Access Journals (Sweden)

    Thorben Burghardt

    2011-04-01

    Full Text Available Search engines are key to finding information on the web. Search presently is free for users financed by targeted advertisement. Today, the current search terms determine the ad placement. In the near future, search-engine providers will make use of detailed user profiles for better ad placement. This puts user privacy at risk. Anonymizing search histories, which is a solution in principle, gives way to a trade-off between privacy and the usability of the data for ad placement. This paper studies this tradeoff systematically. To this end, we implement an algorithm for the anonymization of search histories which is flexible regarding the target function. It can retain frequent terms or terms where corresponding ads are clicked with a high probability, keep up the number of users it can derive interests for, etc. We quantify the usefulness of the anonymized log for ad placement in a broad way, e.g., by estimating the number of ad clicks or of ad impressions, based on marketing data from Yahoo! As a result, anonymized search logs are still useful for ad placement, but this very much depends on the target function.

  18. Extended K-Anonymity Model for Privacy Preserving on Micro Data

    Directory of Open Access Journals (Sweden)

    Masoud Rahimi

    2015-11-01

    Full Text Available Today, information collectors, particularly statistical organizations, are faced with two conflicting issues. On one hand, according to their natural responsibilities and the increasing demand for the collected data, they are committed to propagate the information more extensively and with higher quality and on the other hand, due to the public concern about the privacy of personal information and the legal responsibility of these organizations in protecting the private information of their users, they should guarantee that while providing all the information to the population, the privacy is reasonably preserved. This issue becomes more crucial when the datasets published by data mining methods are at risk of attribute and identity disclosure attacks. In order to overcome this problem, several approaches, called p-sensitive k-anonymity, p+-sensitive k-anonymity, and (p, α-sensitive k-anonymity, were proposed. The drawbacks of these methods include the inability to protect micro datasets against attribute disclosure and the high value of the distortion ratio. In order to eliminate these drawbacks, this paper proposes an algorithm that fully protects the propagated micro data against identity and attribute disclosure and significantly reduces the distortion ratio during the anonymity process.

  6. Bayesian modeling of consumer behavior in the presence of anonymous visits

    Science.gov (United States)

    Novak, Julie Esther

    Tailoring content to consumers has become a hallmark of marketing and digital media, particularly as it has become easier to identify customers across usage or purchase occasions. However, across a wide variety of contexts, companies find that customers do not consistently identify themselves, leaving a substantial fraction of anonymous visits. We develop a Bayesian hierarchical model that allows us to probabilistically assign anonymous sessions to users. These probabilistic assignments take into account a customer's demographic information, frequency of visitation, activities taken when visiting, and times of arrival. We present two studies, one with synthetic and one with real data, where we demonstrate improved performance over two popular practices (nearest-neighbor matching and deleting the anonymous visits) due to increased efficiency and reduced bias driven by the non-ignorability of which types of events are more likely to be anonymous. Using our proposed model, we avoid potential bias in understanding the effect of a firm's marketing on its customers, improve inference about the total number of customers in the dataset, and provide more precise targeted marketing to both previously observed and unobserved customers.

    An anonymous user authentication scheme allows a user, who wants to access a remote application server, to achieve mutual authentication and session key establishment with the server in an anonymous manner. To enhance the security of such authentication schemes, recent researches combined user's biometrics with a password. However, these authentication schemes are designed for single server environment. So when a user wants to access different application servers, the user has to register many times. To solve this problem, Chuang and Chen proposed an anonymous multiserver authenticated key agreement scheme using smart cards together with passwords and biometrics. Chuang and Chen claimed that their scheme not only supports multiple servers but also achieves various security requirements. However, we show that this scheme is vulnerable to a masquerade attack, a smart card attack, a user impersonation attack, and a DoS attack and does not achieve perfect forward secrecy. We also propose a security enhanced anonymous multiserver authenticated key agreement scheme which addresses all the weaknesses identified in Chuang and Chen's scheme.

  9. Evolutionary approach to violating group anonymity using third-party data.

    Science.gov (United States)

    Tavrov, Dan; Chertov, Oleg

    2016-01-01

    In the era of Big Data, it is almost impossible to completely restrict access to primary non-aggregated statistical data. However, risk of violating privacy of individual respondents and groups of respondents by analyzing primary data has not been reduced. There is a need in developing subtler methods of data protection to come to grips with these challenges. In some cases, individual and group privacy can be easily violated, because the primary data contain attributes that uniquely identify individuals and groups thereof. Removing such attributes from the dataset is a crude solution and does not guarantee complete privacy. In the field of providing individual data anonymity, this problem has been widely recognized, and various methods have been proposed to solve it. In the current work, we demonstrate that it is possible to violate group anonymity as well, even if those attributes that uniquely identify the group are removed. As it turns out, it is possible to use third-party data to build a fuzzy model of a group. Typically, such a model comes in a form of a set of fuzzy rules, which can be used to determine membership grades of respondents in the group with a level of certainty sufficient to violate group anonymity. In the work, we introduce an evolutionary computing based method to build such a model. We also discuss a memetic approach to protecting the data from group anonymity violation in this case.

  10. Anonymous Multi-Receiver Identity-Based Authenticated Encryption with CCA Security

    Directory of Open Access Journals (Sweden)

    Chun-I Fan

    2015-10-01

    Full Text Available In a multi-receiver encryption system, a sender chooses a set of authorized receivers and sends them a message securely and efficiently, as the message is well encrypted and only one ciphertext corresponding to the message is generated no matter how many receivers the sender has chosen. It can be applied to video conferencing systems, pay-per-view channels, remote education, and so forth. Due to privacy considerations, an authorized receiver may not expect that his identity is revealed. In 2010, anonymous multi-receiver identity-based (ID-based encryption was first discussed, and furthermore, many works on the topic have been presented so far. Unfortunately, we find that all of those schemes fail to prove the chosen ciphertext attacks (CCA security in either confidentiality or anonymity. In this manuscript, we propose the first anonymous multi-receiver ID-based authenticated encryption scheme with CCA security in both confidentiality and anonymity. In the proposed scheme, the identity of the sender of a ciphertext can be authenticated by the receivers after a successful decryption. In addition, the proposed scheme also is the first CCA-secure one against insider attacks. Moreover, only one pairing computation is required in decryption.

    The Guidelines for Counselling in Infertility describe the purpose, objectives, typical issues and communication skills involved in providing psychosocial care to individuals using fertility services. The Guidelines are presented in six sections. The first section describes how infertility consultations differ from other medical consultations in obstetrics and gynaecology, whereas the second section addresses fundamental issues in counselling, such as what is counselling in infertility, who should counsel and who is likely to need counselling. Section 3 focuses on how to integrate patient-centred care and counselling into routine medical treatment and section 4 highlights some of the special situations which can provoke the need for counselling (e.g. facing the end of treatment, sexual problems). Section 5 deals exclusively with third party reproduction and the psychosocial implications of gamete donation, surrogacy and adoption for heterosexual and gay couples and single women without partners. The final section of the Guidelines is concerned with psychosocial services that can be used to supplement counselling services in fertility clinics: written psychosocial information, telephone counselling, self-help groups and professionally facilitated group work. This paper summarizes the different sections of the Guidelines and describes how to obtain the complete text of the Guidelines for Counselling in Infertility. PMID:11387309

  16. Developments in infertility counselling and its accreditation.

    Science.gov (United States)

    Monach, Jim

    2013-03-01

    Infertility counselling was placed in a unique position by the passage of the Human Fertilisation and Embryology Act 1990 and the requirement that couples being treated should be offered counselling. However professional counselling was, and largely still is, at a stage at which there was no universal agreement on the knowledge, standards or qualifications required for practice. Nevertheless, infertility counselling became the first example of counselling to be required by statute, beyond the more generalised requirement in adoption birth records access. Counselling is intended to describe skilled talking therapy offered by a professional with specific training and qualifications directed to helping individuals and couples to achieve goals they own themselves. The therapeutic intervention of counselling is primarily directed to helping clients in a stressful situation to deploy their own coping skills effectively and thus make the difficult choices inseparable from ART. Counselling outcome research consistently demonstrates the effectiveness of the sort of counselling delivered in assisted conception units with mild-moderate anxiety and depression delivered by skilled and experienced practitioners. This article reviews the role of counsellors as members of the assisted conception clinical team and the status of regulation and accreditation in this very new profession.

  17. Genetic counselling as care of the self.

    Science.gov (United States)

    Leontini, Rose

    2010-07-01

    Genetic counselling has frequently been described as a disciplinary practice, with the goal of 'risk reduction'. In this article another dimension to genetic counselling is considered through the Foucauldian theorization on the care of the self. Drawing on narrative analysis, I examine how one informant undergoing genetic counselling interprets the technique of imagining alternative futures learned through counselling, and transforms it into an ethical practice of self-care. The findings suggest that what may begin as a medical issue with implications for one's health, becomes a meditation over one's disposition towards life, in a way that is consonant with one's desires and values.

    2012-09-01

    Full Text Available Objective: To determine knowledge of folic acid use for neural tube defect (NTD prevention and counseling practices among community pharmacists registered in Ohio.Methods: A cross-sectional study was performed on a random sample (n=500 of community pharmacists registered with the Ohio Board of Pharmacy and practicing in Ohio. A survey previously used by researchers to assess folic acid knowledge and practices among samples of other healthcare provider groups in the United States was adapted with permission for this study. The final tool consisted of 28 questions evaluating the knowledge, counseling practices, and demographics of respondents. The cover letter did not reveal the emphasis on folic acid, and surveys were completed anonymously. The university institutional review board deemed the study exempt.Results: Of the 122 pharmacists who completed the survey, 116 (95.1% knew that folic acid prevents some birth defects. Twenty-eight (22.9% responded that they “always” or “usually” discuss multivitamins with women of childbearing potential, and 19 (15.6% responded that they “always” or “usually” discuss folic acid supplements. Some gaps in knowledge specific to folic acid were revealed. While 63.1% of pharmacists selected the recommended dose of folic acid intake for most women of childbearing potential, 13.1% could identify the dose recommended for women who have had a previous NTD-affected pregnancy. Respondents identified continuing education programs, pharmacy journals/magazines, and the Internet as preferred avenues to obtain additional information about folic acid and NTD.Conclusion: This study represents the first systematic evaluation of folic acid knowledge and counseling practices among a sample of pharmacists in the United States. As highly accessible healthcare professionals, community pharmacists can fulfill a vital public health role by counseling women of childbearing potential about folic acid intake. Educational

    2014-12-01

    Nowadays, with comprehensive employment of the internet, healthcare delivery services is provided remotely by telecare medicine information systems (TMISs). A secure mechanism for authentication and key agreement is one of the most important security requirements for TMISs. Recently, Tan proposed a user anonymity preserving three-factor authentication scheme for TMIS. The present paper shows that Tan's scheme is vulnerable to replay attacks and Denial-of-Service attacks. In order to overcome these security flaws, a new and efficient three-factor anonymous authentication and key agreement scheme for TMIS is proposed. Security and performance analysis shows superiority of the proposed scheme in comparison with previously proposed schemes that are related to security of TMISs. PMID:25352490

    2014-08-01

    Full Text Available We investigate the relation between t-closeness, a well-known model of data anonymization against attribute disclosure, and a-protection, a model of the social discrimination hidden in data. We show that t-closeness implies bd f (t-protection, for a bound function bd f ( depending on the discrimination measure f( at hand. This allows us to adapt inference control methods, such as the Mondrian multidimensional generalization technique and the Sabre bucketization and redistribution framework, to the purpose of non-discrimination data protection. The parallel between the two analytical models raises intriguing issues on the interplay between data anonymization and non-discrimination research in data protection.

    Full Text Available We apply LU decomposition of matrices to present an anonymous bilateral authentication scheme. This paper aims at improving security and providing more excellent performances for remote user authentication scheme. The proposed scheme can provide bilateral authentication and session key agreement, can quickly check the validity of the input password, and can really protect the user anonymity. The security of the proposed scheme is based on the discrete logarithm problem (DLP, Diffie-Hellman problem (DHP, and the one-way hash function. It can resist various attacks such as insider attack, impersonation attack, server spoofing attack, and stolen smart card attack. Moreover, the presented scheme is computationally efficient for real-life implementation.

    2006-01-01

    The security of mobile agent directly decides its usage width in e-commerce. Especially, to protect users' private information is becoming more important now and future. So an anonymous mobile agent security mechanism with the secure authentication infrastructure based on PKI(public key infrastructure) is proposed in the paper. The multi-agent system is programmed by java language and every agent must register itself in CA(certificate authority) before working in the net and express his legit identity which is temptly produced and used only once. The CA ensures the legal of all agents' identity which take part in communicaiton or trade. And every user agent identity only is used once which makes other agents cannot decipher users' private information. The security mechanism of the multi-agent system implements anonymity, integrity, data confidentiality of mobile agent based on the MH(multiple hop) integrity protection regard to PKI limit.

    2014-02-01

    With the development of wireless networks and medical sensors, wireless body area networks are playing more and more important role in the field of healthcare service. The data transmitted in WBANs is very sensitive since it will be used in clinical diagnoses or measurements. Therefore, security and privacy of communication in WBANs derive increasing attentions from the academia and industry. In this paper, we propose an identity (ID)-based efficient anonymous authentication scheme for WBANs using elliptic curve cryptosystem (ECC). Due to the ID-based concept, there is no certificate is needed in the proposed scheme. Moreover, the proposed scheme not only provides mutual authentication between the client and the application provider but also provides client anonymity. Performance analysis shows that improvements of 50.58% and 3.87% in the client side and the application provider side separately. Then the proposed scheme is more suitable for WBANs. PMID:24481718

    2014-01-01

    Public health interventions comprising information dissemination to affect behavioral adjustment have long been a significant component of public health campaigns. However, there has been limited development of public health intervention systems to make use of advances in mobile computing and telecommunications technologies. Such developments pose significant challenges to privacy and security where potentially sensitive data may be collected. In our previous work we identified and demonstrated the feasibility of using mobile devices as anonymous public health data collection devices as part of a Health Participatory Sensing Network (HPSN). An advanced capability of these networks extended in this paper would be the ability to distribute, apply, report on and analyze the usage and effectiveness of targeted public health interventions in an anonymous way. In this paper we describe such a platform, its place in the HPSN and demonstrate its feasibility through an implementation. PMID:25570789

  14. Distributed anonymous data perturbation method for privacy-preserving data mining

    Institute of Scientific and Technical Information of China (English)

    Feng LI; Jin MA; Jian-hua LI

    2009-01-01

    Privacy is a critical requirement in distributed data mining. Cryptography-based secure multiparty computation is a main approach for privacy preserving. However, it shows poor performance in large scale distributed systems. Meanwhile, data perturbation techniques are comparatively efficient but are mainly used in centralized privacy-preserving data mining (PPDM). In this paper, we propose a light-weight anonymous data perturbation method for efficient privacy preserving in distributed data mining. We first define the privacy constraints for data perturbation based PPDM in a semi-honest distributed environment. Two protocols are proposed to address these constraints and protect data statistics and the randomization process against collusion attacks: the adaptive privacy-preserving summary protocol and the anonymous exchange protocol. Finally, a distributed data perturbation framework based on these protocols is proposed to realize distributed PPDM. Experiment results show that our approach achieves a high security level and is very efficient in a large scale distributed environment.

  20. SW-SDF Based Personal Privacy with QIDB-Anonymization Method

    Directory of Open Access Journals (Sweden)

    Kiran P

    2012-08-01

    Full Text Available Personalized anonymization is a method in which a guarding node is used to indicate whether the record owner is ready to reveal its sensitivity based on which anonymization will be performed. Most of the sensitive values that are present in the private data base do not require privacy preservation since the record owner sensitivity is a general one. So there are only few records in the entire distribution that require privacy. For example a record owner having disease flu doesn’t mind revealing his identity as compared to record owner having disease cancer. Even in this some of the record owners who have cancer are ready to reveal their identity, this is the motivation for SW-SDF based Personal Privacy. In this paper we propose a novel personalized privacy preserving technique that over comes the disadvantages of previous personalized privacy and other anonymization techniques. The core of this method can be divided in to two major components. The first component deals with additional attribute used in the table which is in the form of flags which can be used to divide sensitive attribute. Sensitive Disclosure Flag (SDF determines whether record owner sensitive information is to be disclosed or whether privacy should be maintained. The second flag that we are using is Sensitive Weigh (SW which indicates how much sensitive the attribute value is as compared with the rest. Second section deals with a novel representation called Frequency Distribution Block (FDB and Quasi–Identifier Distribution Block(QIDB which is used in anonymization. Experimental result show that it has lesser information loss and faster execution time as compared with existing methods.

    In this study, we investigated the status of researching drug information online, and the type of Internet user who uses anonymous Web communities and websites. A Web-based cross-sectional survey of 10875 male and female Internet users aged 16 and over was conducted in March 2010. Of 10282 analyzed respondents, excluding medical professionals, about 47% reported that they had previously searched the Internet for drug information and had used online resources ranging from drug information search engines and pharmaceutical industry websites to social networking sites and Twitter. Respondents who had researched drug information online (n=4861) were analyzed by two multivariable logistic regressions. In Model 1, the use of anonymous websites associated with age (OR, 0.778; 95% CI, 0.742-0.816), referring to the reputation and the narrative of other Internet users on shopping (OR, 1.640; 95% CI, 1.450-1.855), taking a prescription drug (OR, 0.806; 95% CI, 0.705-0.922), and frequent consulting with non-professionals about medical care and health (OR, 1.613; 95% CI, 1.396-1.865). In Model 2, use of only anonymous websites was associated with age (OR, 0.753; 95% CI, 0.705-0.805), using the Internet daily (OR, 0.611; 95% CI, 0.462-0.808), taking a prescription drug (OR, 0.614; 95% CI, 0.505-0.747), and experience a side effect (OR, 0.526; 95% CI, 0.421-0.658). The analysis revealed the profiles of Internet users who researched drug information on social media sites where the information providers are anonymous and do not necessarily have adequate knowledge of medicine and online information literacy.

    2008-01-01

    We investigated the role of anonymity, reciprocity, and conformity for voluntary contributions, based on a natural field experiment conducted at a national park in Costa Rica. Contributions made in public in front of the solicitor were 25 percent higher than contributions made in private. Giving subjects a small gift before requesting a contribution increased the likelihood of a positive contribution. At the same time, however, the conditional contribution decreased. The total effect of givin...

    This paper presents decentralized formation controls for a team of anonymous mobile robots performing a task through cooperation. Robot teams are required to generate and maintain various geometric patterns adapting to environmental changes in many cooperative robotics applications. In particular, all robots must continue to strive toward achieving the team’s mission even if some members fail to perform their role. Toward this end, formation control approaches are proposed under the condition...

    This study examines an Israeli lesbian woman's travel experience based on the analysis of her published diary. The comparison of her experience and attitudes towards various spaces (e.g. her apartment, open spaces near her home, and locations in which she is involved in tourist activity) suggests that her perception of the space as 'free from people she knows' allows her and her partner to benefit from anonymity, live a lesbian lifestyle and benefit from sense of existential...

    When the phenomenon of tax evasion is discussed, both scholars and authorities agree on the fact that, although essential, classical enforcements are not enough to ensure tax compliance: some other forms of incentives must be adopted. The paper’s aim is to experimentally test the role of different non- monetary incentives for tax compliance: participants have been treated with different experimental conditions, which differ in the role played by anonymity. Indeed, subjects have been informed ...

    The role of anonymity in giving is examined in a field experiment performed in thirty Dutch churches. For a period of 29 weeks, the means by which offerings are gathered is determined by chance, prescribing for each offering the use of either `closed' collection bags or open collection baskets. When using baskets, attendants' contributions can be identified by their direct neighbors, and attendants can observe the total amount given by the people who preceded them. Initially, contributions to...

    When measuring poverty with counting measures, are there conditions ensuring that poverty reduction not only reduces the average poverty score further but also decreases deprivation inequality among the poor more, thereby emphasizing improvements among the poorest of the poor? In the case of a non-anonymous assessment, i.e. when we can track poverty experiences of the same individuals or households using panel datasets, we derive three conditions whose fulfillment allows us to conclude that m...

    When measuring poverty with counting measures, it is worth inquiring into the conditions prompting poverty reduction which not only reduce the average poverty score further but also decrease deprivation inequality among the poor, thereby emphasizing improvements among the poorest of the poor. For comparisons of cross-sectional datasets of the same society in different periods of time (i.e. an anonymous assessment), Lasso de la Vega (2010) and Alkire and Foster (2011) developed a first-order d...

    International audience This paper characterizes a recently proposed anonymous file sharing system, OneSwarm. This characterisation is based on measurement of several aspects of the OneSwarm system such as the nature of the shared and searched content and the geolocation and number of users. Our findings indicate that, as opposed to common belief, there is no significant difference in downloaded content between this system and the classical BitTorrent ecosystem. We also found that a majorit...

  12. Local and global recoding methods for anonymizing set-valued data

    In this paper, we study the problem of protecting privacy in the publication of set-valued data. Consider a collection of supermarket transactions that contains detailed information about items bought together by individuals. Even after removing all personal characteristics of the buyer, which can serve as links to his identity, the publication of such data is still subject to privacy attacks from adversaries who have partial knowledge about the set. Unlike most previous works, we do not distinguish data as sensitive and non-sensitive, but we consider them both as potential quasi-identifiers and potential sensitive data, depending on the knowledge of the adversary. We define a new version of the k-anonymity guarantee, the k m-anonymity, to limit the effects of the data dimensionality, and we propose efficient algorithms to transform the database. Our anonymization model relies on generalization instead of suppression, which is the most common practice in related works on such data. We develop an algorithm that finds the optimal solution, however, at a high cost that makes it inapplicable for large, realistic problems. Then, we propose a greedy heuristic, which performs generalizations in an Apriori, level-wise fashion. The heuristic scales much better and in most of the cases finds a solution close to the optimal. Finally, we investigate the application of techniques that partition the database and perform anonymization locally, aiming at the reduction of the memory consumption and further scalability. A thorough experimental evaluation with real datasets shows that a vertical partitioning approach achieves excellent results in practice. © 2010 Springer-Verlag.

    SPKI is a proposed standard for public-key certificates. One important property of SPKI is that SPKI is key-oriented rather than name-oriented, and the public-key is globally unique. In this paper we propose an anonymous paymentscheme based on SPKI aiming at the problem of anonymous payment in B2C e-commerce. In the scheme we use the key-oriented characteristic of SPKI to link the public key to the account, and use authorization certificates to pay. The scheme achieves the anonymity very well.

    Introduction Sexual problems are common with cardiovascular disease, and can negatively impact quality of life. To address sexual problems, guidelines have identified the importance of sexual counselling during cardiac rehabilitation, yet this is rarely provided. The Cardiac Health and Relationship Management and Sexuality (CHARMS) intervention aims to improve the provision of sexual counselling in cardiac rehabilitation in Ireland. Methods and analysis This is a multicentre pilot study for the CHARMS intervention, a complex, multilevel intervention delivered within hospital-based cardiac rehabilitation programmes. The intervention includes (1) training in sexual counselling for staff, (2) a staff-led patient education and support intervention embedded within the cardiac rehabilitation programme, (3) a patient information booklet and (4) an awareness raising poster. The intervention will be delivered in two randomly selected cardiac rehabilitation centres. In each centre 30 patients will be recruited, and partners will also be invited to participate. Data will be collected from staff and patients/partners at T1 (study entry), T2 (3-month follow-up) and T3 (6-month follow-up). The primary outcome for patients/partners will be scores on the Sexual Self-Perception and Adjustment Questionnaire. Secondary outcomes for patients/partners will include relationship satisfaction; satisfaction with and barriers to sexual counselling in services; sexual activity, functioning and knowledge; physical and psychological well-being. Secondary outcomes for staff will include sexuality-related practice; barriers to sexual counselling; self-ratings of capability, opportunity and motivation; sexual attitudes and beliefs; knowledge of cardiovascular disease and sex. Fidelity of intervention delivery will be assessed using trainer self-reports, researcher-coded audio recordings and exit interviews. Longitudinal feasibility data will be gathered from patients/partners and staff via

    Full Text Available Data mining is the process of analyzing data. Data Privacy is collection of data and dissemination of data. Privacy issues arise in different area such as health care, intellectual property, biological data, financial transaction etc. It is very difficult to protect the data when there is transfer of data. Sensitive information must be protected. There are two kinds of major attacks against privacy namely record linkage and attribute linkage attacks. Research have proposed some methods namely k-anonymity, ℓ-diversity, t-closeness for data privacy. K-anonymity method preserves the privacy against record linkage attack alone. It is unable to prevent address attribute linkage attack. ℓ-diversity method overcomes the drawback of k-anonymity method. But it fails to prevent identity disclosure attack and attribute disclosure attack. t-closeness method preserves the privacy against attribute linkage attack but not identity disclosure attack. A proposed method used to preserve the privacy of individuals sensitive data from record and attribute linkage attacks. In the proposed method, privacy preservation is achieved through generalization by setting range values and through record elimination. A proposed method overcomes the drawback of both record linkage attack and attribute linkage attack.

  17. On Enhancing Data Utility in K-Anonymization for Data without Hierarchical Taxonomies

    Full Text Available K-anonymity is the model that is widely used to protect the privacy of individuals in publishing micro-data. It could be defined as clustering with constrain of minimum k tuples in each group. K-anonymity cuts down the linking confidence between sensitive information and specific individual by the ration of 1/k. However, the accuracy of the data in k-anonymous dataset decreases due to information loss. Moreover, most of the current approaches are for numerical attributes or in case of categorical attributes they require extra information such as attribute hierarchical taxonomies which often do not exist. In this paper we propose a new model, based on clustering, defining the distance between tuples including numerical and categorical attributes which does not require extra information and present the SpatialDistance (SD heuristic algorithm. Comparisons of experimental results on real datasets between SD algorithm and existing well-known algorithms show that SD performs the best and offers much higher data utility and reduces the information loss significantly.

    Thanks to the rapid technological convergence of wireless communications, medical sensors and cloud computing, Wireless Body Area Networks (WBANs) have emerged as a novel networking paradigm enabling ubiquitous Internet services, allowing people to receive medical care, monitor health status in real-time, analyze sports data and even enjoy online entertainment remotely. However, because of the mobility and openness of wireless communications, WBANs are inevitably exposed to a large set of potential attacks, significantly undermining their utility and impeding their widespread deployment. To prevent attackers from threatening legitimate WBAN users or abusing WBAN services, an efficient and secure authentication protocol termed 1-Round Anonymous Authentication Protocol (1-RAAP) is proposed in this paper. In particular, 1-RAAP preserves anonymity, mutual authentication, non-repudiation and some other desirable security properties, while only requiring users to perform several low cost computational operations. More importantly, 1-RAAP is provably secure thanks to its design basis, which is resistant to the anonymous in the random oracle model. To validate the computational efficiency of 1-RAAP, a set of comprehensive comparative studies between 1-RAAP and other authentication protocols is conducted, and the results clearly show that 1-RAAP achieves the best performance in terms of computational overhead.
