Averting Intruder Attack on Social Network by Data Sanitization

IJCSEC Front Page

Online Social Networks offer for social interactions and information sharing among peoples, but it includes security and privacy issues. OSNs allow users to limit access to shared data; OSNs currently do not provide any mechanism to enforce privacy concerns over data associated with multiple users. To overcome this, we put forward an approach which supports the protection of shared data associated with multiple users in OSNs. We are developing an access control model to capture the core of shared authorization requirements, along with a multiparty policy specification scheme and a policy enforcement mechanism.
