In recent years, online social networks (OSNs) have become an important part of daily life and become a portal for millions of Internet users. These OSNs provide attractive means for digital interactions between social network and information sharing, but also a number of security and privacy issues are increase. The online social networks also allow the user to control the shared data and presently do not provide any mechanism to enforce concerns of privacy and security over data associated with multiple users. To solve this problem, we propose a systematic approach for enabling the shared data in OSNs. An access control model is formulated to capture the essence of multiparty authorization requirements, along with a multiparty policy specification system and a policy enforcement mechanism. We begin by investigate how to control lacks for shared data in OSNs based on the relationship between the user, data and their data sharing patterns. Based on the sharing patterns, we make a Multi party Access Control (MPAC) model to control the features of multiparty authorization requirements. In our MPAC model contains a multiparty policy specification system. Also this model provides a voting mechanism to avoid conflicts.
