Abstract

Online social networks (OSNs), such as Facebook, Twitter, and Google+, have become a portal for hundreds of millions of Internet users. According to September-2013 reports Facebook consists of 1.2 billion users. There are now over 550 million registered users for Twitter and over 1 billion with Google+ enabled accounts in Google+. Online social networks (OSNs) have experienced tremendous growth in recent years. OSNs provide built-in mechanisms enabling users to communicate and share information with other members. Although OSNs currently provide simple access control mechanisms allowing users to govern access to information contained in their own spaces, users unfortunately have no control over data residing outside their spaces. For instance, if a user posts a comment in a friend’s space she/he can’t specify which user can view the comment. OSNs provide built in mechanisms enabling users to communicate and share information with other members. In existing system there is only access control over shared data in OSNs. An MPAC model was formulated, along with a multiparty policy specification scheme and corresponding policy evaluation mechanism. It provides a mechanism that offers limited privacy over data associated with multiple users. The main aim of the paper is to develop a novel solution for privacy conflict detection and resolution for collaborative data sharing in OSNs. This conflict resolution mechanism considers privacy-sharing tradeoff by quantifying privacy risk and sharing loss.
