PPL: PrimeLife Privacy Policy Engine

Web 2.0 introduces new breaches in the privacy protection of personal data. Most of the users of such Internet media are not aware about the risks of publishing personal information. These threats can lead to identity thefts, scams, and cyber criminal attacks. In this paper we propose a framework, based on a privacy policy language called PPL (Primelife Policy Language), in which every user can control his personal information by imposing access and usage control restrictions. Sticky policies are used in order to keep the trace ability of these privacy constrains when the data is travelling from a domain to another. In this paper we detail the demo that shows how the user can express his privacy preferences, how the servers will comply with the privacy constraints stated in the sticky policies and how the data is shared with third parties according to the user´s whishes.
