摘要：Online social networks have experienced tremendous growth in recent years and become a de facto portal for hundreds of millions of Internet users. These online social networks offer attractive means for digital social interactions and information sharing, but also move up a number of privacy and security issues. While online social networks allow users to control access to shared data, they presently do not provide any mechanism to enforce privacy concerns over data associated with many users. To this end, we propose an approach to enable the protection of shared data associated with multiple users in online social networks. We prepare an access control model to take into custody the essence of multiparty authorization requirements, along with a policy enforcement mechanism and a multiparty policy specification system. This paper we going study about model and mechanism systems in analysis of multiparty access control. The correctness of realization of an access control model is based on the premise that the access control model is valid...We pursue an efficient solution to facilitate collaborative management of common data in OSNs. We begin b y investigate how the lack of multiparty access control for data sharing in OSNs can undermine the protection of user data. Some distinctive data sharing patterns with respect to multiparty authorizatio n in OSNs are also identified. We make official a Multiparty Access Control (MPAC) model for OSNs
