Online Social Networks (OSNs) are essentially designed to facilitate people to share personal and public information and make social connections with others. These OSNs propose good looking means for digital social communications and information distribution, but also raise a number of security and privacy issues. Whereas OSNs allow users to control access to shared data, at the moment they do not provide any mechanism to implement privacy concerns over data connected with multiple users. The proposed approach is to facilitate the defense of shared data associated with many users in OSNs.
