C ount data arise in various organizational settings. When the release of such data is sensitive, organizations need information-disclosure policies that protect data confidentiality while still providing data access. In contrast to extant disclosure policies, we describe a new policy for count tables that is based on disclosing only the sufficient statistics of a flexible discrete distribution...

Limited studies exist evaluating the multidisciplinary team (MDT) decision-making process and its outcomes. This study evaluates the MDT determination of the likelihood of child sexual abuse (CSA) and its association to the outcome of the child protective services (CPS) disposition. A retrospective cohort study of CSA patients was conducted. The MDT utilized an a priori Likert rating scale to d...

OBJECTIVES We explored factors influencing sexual behavior, disclosure of same-sex behavior, and condom-use practices among Black bisexual men. METHODS We conducted semistructured interviews with 38 Black men in Atlanta, Georgia, who reported having had oral, vaginal, or anal sex with both men and women in the prior 6 months. RESULTS Participants described approaches to disclosure of same-s...

We live in an increasingly mobile world, which leads to the duplication of information across domains. Though organizations attempt to obscure the identities of their constituents when sharing information for worthwhile purposes, such as basic research, the uncoordinated nature of such environment can lead to privacy vulnerabilities. For instance, disparate healthcare providers can collect info...

This paper presents a decision-theoretic approach to data disclosure problems. The approach is innovative because (i) it offers a theoretical framework to develop optimality criteria for the choice of the best form of data release, (ii) it recognizes the different perspectives of the statistical agency and of the users of the data in assessing the extent of disclosure and the quality of the use...

Little information is available about sexual risk, protective, and disclosure practices among Black bisexually active men and how these may be amenable to intervention when necessary. In-depth interviews were conducted with 30 at-risk urban Black men who have sex with both men and women (MSMW). Participants reported protecting themselves and their partners through routine HIV testing, using con...

We present an approach for evaluating disclosure risks for fully synthetic categorical data. The basic idea is to compute probability distributions of unknown confidential data values given the synthetic data and assumptions about intruder knowledge. We use a “worst-case” scenario of an intruder knowing all but one of the records in the confidential data. To create the synthetic data, we use a ...

Microaggregation is a method used by statistical agencies to limit the disclosure of sensitive microdata. It has been proven that microaggregation is an NP-hard problem when more than one variable is microaggregated at the same time. To solve this problem in a heuristic way, a few methods based on projections have been introduced in the literature. The main drawback of such methods is that the ...

A paper survey of 489 Chinese college students was conducted in spring, 2012 to test a conceptual model of online information disclosure in social media. It shows that young Chinese SNS users' prior negative experience of online disclosure significantly increased their online privacy concerns and their perceived risk. Their online privacy concerns undermined their trust of online companies, mar...
