Abstract
A new generation of distributed systems and applications
rely on the cooperation of diverse user populations moti-
vated by self-interest. While they can utilize "reputation
systems" to reduce selfish behaviors that disrupt or manipu-
late the network for personal gain, current reputations face
a key challenge in large dynamic networks: vulnerability to
peer collusion. In this paper, we propose to dramatically
improve the accuracy of reputation systems with the use
of a statistical metric that measures the "reliability" of a
