Bring Reputation System to Social Network in the Maze P2P File-Sharing System

Much work has been done to address the need for reputation systems in real deployed peer-to-peer networks. Unlike some previous researches, we now focus on deploying a reputation system in a large deployed peer-to-peer file sharing network; Maze. There are several potential problems in mapping EigenTrust to our system and we propose two methods to improve it. First, we introduce a location-aware pre-trusted peers’ choice algorithm to ensure the fairness. Then we reduce the impact of colluders by prompting trust relationships among peers in the social network. This improved reputation system has been proven to successfully imply the peers’ contributions, while at the same time, action against the colluders.
