Sybils are fake identities in any network. Sybils cannot be matched to a physical identity. There are several mechanisms to detect Sybil Attacks in networks. In this paper we are discussing Sybil Defense Mechanisms in Social Networks. We have included the working principles of existing Decentralized Sybil Defenses and the assumptions under which these mechanisms operate. We have also gathered information supporting the fact that the assumptions about Social Networks are flawed. Certain drawbacks of each mechanism have also been looked into. © Research India Publications.
