The EigenTrust Algorithm for Reputation Management in P2P Networks

by Sepandar D. Kamvar, Mario T. Schlosser, Hector Garcia-molina - in Proceedings of the 12th International World Wide Web Conference (WWW 2003 , 2003
"... Peer-to-peer file-sharing networks are currently receiving much attention as a means of sharing and distributing information. However, as recent experience with P2P networks such as Gnutella shows, the anonymous, open nature of these networks offers an almost ideal environment for the spread of self ..."

A Fuzzy Reputation Management System with Punishment Mechanism for P2P Network

by Zhengbing Hu, Huaiqing Lin, Yonghong Zhou
"... Abstract—One way to minimize threats in P2P system is to exploit reputation to help evaluate the trustworthiness and predict the future behaviors of peers. In this paper, a set of parameters are identified for describing the trust of a peer. And a trust model based on fuzzy techniques is presented. ..."

A Trust Management for Peer 2 Peer Information Systems

by Suraj Suryawanshi, Pavan Gujjar, Panduranga Rao
"... Abstract- Due to the open nature of P2P system exposes them to malicious activity. P2P system means computer in the system can act as both client and server. In a P2P network, the peers are computer systems which are connected to each other via the internet. Files can be shared directly between syst ..."

recommendations with service and recommendation contexts.A malicious peer performs both service and recommendation-based attacks. Uploading a virus infected (or) an inauthentic file is a service based attack. Self-Organizing Trust Model (SORT) detects the service based attack and recommendation based attack

Authenticating contrast and brightness adjusted images using distributed source coding and expectation maximization
