Thwarting P2P Pollution Using Object Reputation
Kevin S. Walsh, Emin Gün Sirer · 2005
This paper describes Credence, a distributed object reputation management scheme for combating content pollution in peer-to-peer filesharing systems. Credence enables honest peers to assess the authenticity of online content by securely tabulating and managing endorsements from other peers. Credence employs a novel voter correlation scheme to weight peer opinions, which gives rise to favorable incentives and system dynamics. We present simulation results indicating that our system is scalable, efficient, and robust. 1
