An approach to disambiguate the identity information between a Sybil and a Non-Sybil by using the social circles and weighted graphs is being presented in this paper. The disambiguation is done in two phases the Static phase and the Dynamic phase. In Static phase, the social circles are generated through the extraction and pruning of social networks. In Dynamic phase, the initial parameters are further refined by the use of polling from the other users. The approach provides a methodology to monitor existing identity information, applicable to addressing issues like identity theft, online fraud and lateral surveillance.
