Privacy Access Control Mechanism For  Online social Network

Online social networks (OSNs) have experienced tremendous growth in recent years and become a de facto portal for hundreds of millions of Internet users. These OSNs offer attractive means for digital social interactions and information sharing, but also raise a number of security and privacy issues.  While OSNs allow users to restrict access to shared data, they currently do not provide any mechanism to enforce privacy concerns over data associated with multiple users.

To this end, we propose an approach to enable the protection of shared data associated with multiple users in OSNs. We formulate an access control model to capture the essence of multiparty authorization requirements, along   with   a   multiparty   policy   specification   scheme   and   a   policy   enforcement mechanism.  Besides, we present a logical representation of our access control model which allows us to leverage the features of existing logic solvers to perform various analysis tasks on our model.  

We also discuss a proof-of-concept prototype of our approach as part of an application in Face-book and provide usability study and system evaluation of our method. The existence of online sol networks that include person specific information creates opportunities various applications ranging from marketing to community organization

On the other hand, security and privacy concerns need to be ad creating such applications. Improving social network access control systems appears as the first step toward addressing the existing security and privacy concerns related to online social networks. To address some of the current limitations, we have created an experimental social network  using synthetic data which we then use to test the efficacy of the semantic reasoning based approaches we have previously suggested.
