Social networking is one of the major technological phenomena of the Web 2.0, with hundreds of millions of subscribed users. Social networks enable a form of self-expression for users and help them to socialize and share content with other users. In spite of the fact that content sharing represents one of the prominent features of existing Social network sites, they do not provide any mechanisms for collective management of privacy settings for shared content. In this paper, using game theory, the authors model the problem of collective enforcement of privacy policies on shared data. In particular, they propose a solution that offers automated ways to share images based on an extended notion of content ownership.
