This paper critically examines some recently proposed RFID privacy models. It shows that some models suffer from weaknesses such as insufficient generality and unrealistic assumptions regarding the adversary’s ability to corrupt tags. We propose a new RFID privacy model that is based on the notion of indistinguishability and that does not suffer from the identified drawbacks. We demonstrate the easy...
We put forward a general model intended for assessment of system security against passive eavesdroppers, both quantitatively (how much information is leaked) and qualitatively (what properties are leaked). To this purpose, we extend information hiding systems (ihs), a model where the secret-observable relation is represented as a noisy channel, with views: basically, partitions of the state-space...
The rapid progress of human genome studies leads to a strong demand of aggregate human DNA data (e.g, allele frequencies, test statistics, etc.), whose public dissemination, however, has been impeded by privacy concerns. Prior research shows that it is possible to identify the presence of some participants in a study from such data, and in some cases, even fully recover their DNA sequences. A critical...
