Towards a Theory of Data Entanglement,ata in a way that makes it hard to corrupt the data of any one user without corrupting the data of all users. AONI can be a useful defense against negligent or dishonest storage providers who might otherwise be tempted to discard documents belonging to users without much clout. We show that, if all

While there are significant privacy-preservation advantages to the use of smart cards anonymously created and bought in public places (stores, libraries, etc), a major difficulty is that, for huge data repositories and limited-capacity portable storage devices, it is no

Possibilistic Information Flow Control in the Presence of Encrypted Communication,investigate the flow of information within distributed systems, it has proved to be rather difficult to capture the notion of encrypted channels in such a framework. In this paper, we extend the framework . for possibilistic information flow in order to distinguish between the information flow due t

Parameterized Authentication,m. . moves beyond the traditional approach to security by acknowledging that identity verification cannot always produce perfect results. Our model addresses such inherent imperfections by introducing a metric, the Authentication Parameter, that captures the overall ”quality” of authentication. We d

Daciberg Lima Gonçalves,John Guaschion. To circumvent this problem, we identified the subset of well-founded privacy policies which enjoy the property that the result of our algebraic operations can be turned into a coherent privacy policy again. This enables existing privacy policy enforcement mechanisms to deal with our algebraic ex
