Abstract
Rumors and defamation are now becoming a main threat to Online Social Networks (OSNs). To prevent them, Real Name System (RNS) was proposed, but has been proved vulnerable by the data leakage in South Korea. In this paper, we propose a new identity model, Social Authentication Identity (SAI), to trace rumor-makers. In SAI, only a small number of users (called s) are required to be authenticated by RNS. And the others are authenticated by vouching of friends, called social authentication. We evaluate factors that affect the efficiency of SAI. Results show that selecting s in communities are the best strategy, comparing with random and maximum degree strategies. We also provide an social tracing mechanism to trace down rumor-makes. Analysis shows our social tracing is robust enough to defend Sybil attacks.
