Privacy and Utility of Inference Control Mechanisms for Social Computing Applications
2016
Proceedings of the 11th ACM on Asia Conference on Computer and Communications Security - ASIA CCS '16

To the best of our knowledge, ours is the first work to articulate precise privacy and utility goals of inference control mechanisms for third-party applications in social computing platforms. ...
Our notions of privacy and utility are highly targeted, mirroring the set up of social computing platforms, in which users specify their privacy preferences and third-party applications focus their accesses ...
