A Near Optimal Social Network Defense against Sybil attacks project explains about implementing a Sybil guard method for controlling attacks.
Sybil attacks are commonly seen in peer to peer distribution systems when a single user will create multiple fake identities and try to work on it as they were from different nodes.
Because of this attacks genuine users are facing problem in collaborative tasks such as Byzantine failure defense.
This paper proposes a social networking defense method which works on user identities. This method mainly concentrates on trust that is established between users regularly.
If there is a fake account it is hard to maintain trust between users for a long time, based on the graphical view of these results Sybil attack is calculated.
