Secure Authentication and Cyber Crime Mitigation for Social Networking Sites

With the advent of online social networking sites, its usage has grown dramatically, now rivaling search engines as the most visited Internet sites. Even though these OSNs offer attractive means for digital social interactions and data sharing, they raise a number of cyber issues on security and privacy. Usually OSNs allow users to restrict access shared data but there had not been any mechanism to enforce security and privacy concerns over data associated with multiple users. One of the main issues in todays OSNs is to give users the ability with which they can control the messages posted on their private space to avoid displaying of unwanted contents. The proposed framework creates firewall in network security. It gives close wall security while accessing the Social Network sites. It also enables the protection of shared data with multi users virtual environment in OSNs. And it also allows OSN users to have a direct control on the messages posted on their walls and a secured login method is provided to avoid cyber attacks like hacking, Phishing and Social Engineering. These are achieved by using RSA Algorithm.
