Voluntary disclosure of personal information is becoming more and more widespread with the advent of Web 2.0 services. Publishing such information constitutes new kinds of threats, such as further reinforcing already existing profiling techniques through correlation of perceived user activities to those publicly disclosed, but the most obvious of all is the intrinsic threat that malicious third parties collect and combine information we publish about ourselves. In this paper, we evaluate currently existing solutions that are destined for addressing this issue, then propose a model of our own for providing access control for a user over information she published and analyse our implementation thereof.
