The attacks occur using interactions between the trading peers as a transaction takes place. In this paper propose a Sybil attack an active attack it means some data is missing in transferring the data from one place to another place this is called active attack. And passive attack means data is not missing in transferring the data from one place to another place this is called passive attack. a central authority control is used in existing system. In this proposed system two techniques we are using Sybil trust central authority control and Homogeneous configuration. In this approach duplicated Sybil attack peers can be identified as the neighbor peers become familiar and hence more trusted to each other. Security and performance analysis shows that Sybil attack can be minimized by this proposed neighbor similarity trust. Each peer has an identity which is either honest or Sybil., International Journal of Scientific Research in Computer Science Engineering and Information Technology, 2017, CSEIT1722350
