Access Policy Management For OSN Using Network Relationships

In the online social networks (OSN) users and resources are interconnected via various types of relationships. The relationships are one-to-one, one-to-many, many-to-one, and many-to-many like that. Now a day’s online social networks plays crucial role to monitor and to control the access of the resources. In the OSN, online provider should be enabled to specify which access permission can be granted in terms of existing relationships. In this work we used user-to-user relationship based access control model. Access control policies decide which permissions can be granted to the requested users based on their requests and we are using two path checking algorithms namely DFS and BFS to determine the path existence between users as well as the requested user is authenticated user or not.
