Marti, Sergio and Garcia-Molina, Hector (2003) Identity Crisis: Anonymity vs. Reputation in P2P Systems. In: Third IEEE International Conference on Peer-to-Peer Computing (P2P 2003), September 1-3, 2003, Linkoping, Sweden.
The effectiveness of reputation systems for peer-to-peer resource-sharing networks is largely dependent on the reliability of the identities used by peers in the network. Much debate has centered around how closely one's pseudo-identity in the network should be tied to their real-world identity, and how that identity is protected from malicious spoofing. In this paper we investigate the cost in efficiency of two solutions to the identity problem for peer-to-peer reputation systems. Our results show that, using some simple mechanisms, reputation systems can provide a factor of 4 to 20 improvement in performance over no reputation system, depending on the identity model used.
