Publishing Microdata with a Robust Privacy Guarantee
Today, the publication of microdata poses a privacy threat. Vast research has striven to define the privacy condition that microdata should satisfy before it is released, and devise algorithms to anonymize the data so as to achieve this condition. Yet, no method proposed to date explicitly bounds the percentage of information an adversary gains after seeing the published data for each sensitive...
متن کاملPrivacy-preserving publishing microdata with full functional dependencies
Article history: Received 23 January 2010 Received in revised form 30 October 2010 Accepted 2 November 2010 Available online 10 November 2010 Data publishing has generated much concern on individual privacy. Recent work has shown that different background knowledge can bring various threats to the privacy of published data. In this paper, we study the privacy threat from the full functional dep...
متن کاملPublishing Skewed Sensitive Microdata
A highly skewed microdata contains some sensitive attribute values that occur far more frequently than others. Such data violates the “eligibility condition” assumed by existing works for limiting the probability of linking an individual to a specific sensitive attribute value. Specifically, if the frequency of some sensitive attribute value is too high, publishing the sensitive attribute alone...
متن کاملSLOMS: A Privacy Preserving Data Publishing Method for Multiple Sensitive Attributes Microdata
Multi-dimension bucketization is a typical method to anonymize multiple sensitive attributes. However, the method leads to low data utility when microdata have more sensitive attributes. In addition, the methods do not generalize quasi-identifiers, which make the anonymous data vulnerable to suffer from linked attacks. To address the problems, the paper proposes a SLOMS method. The method verti...
متن کاملCan Pseudonymity Really Guarantee Privacy?
One of the core challenges facing the Internet today is the problem of ensuring privacy for its users. It is believed that mechanisms such as anonymity and pseudonymity are essential building blocks in formulating solutions to address these challenges and considerable eeort has been devoted towards realizing these primitives in practice. The focus of this eeort, however, has mostly been on hidi...
