Prophylactic online social network based on user preference with privacy preservation technique

Computer Engineering

Users and resources in online social networks(OSNs) are interconnected via various types of relationships. In particular, user to user relationships from the basis of the OSN structure, and play a significant role in specifying and enforcing access control. Individual users and the OSN provider should be enabled to specify which access can be granted in tetms of existing relationships. In the paper proposed system a novel user to user relationship based accesd control(UURAC) model for OSN systems that utilizes regular expression notation for such policy specification. Access control policies on users and resources are composed in terms of requested action, multiple relationship types, the starting point of the evaluation, and the number of hops on the path. In this system, Mutual Balanced privacy preservation Algorithm (MBPA) is used to determine whether the required relationship path between users to be offetef or not. The opportunity to every OSN users to offer the right privacy for all thier friends in the network. This approach gives the way to protect our friends from the unrelated friend's network. Access control policies on users and resources are composed in terms of requested action, multiple relationship types. To validate the feasibility of our approach by implementing a prototype system and evaluating the performance of these two algorithms.
