Evaluating Reputation Systems for Document Authenticity

Abstract

There has been significant interest recently in designing reputation systems to address the problem of file authenticity in P2P networks. However, many of the systems proposed make different assumptions, and cannot easily be compared. The development of a model to evaluate such systems is imperative to quantitatively study such reputation systems. In this paper, we outline several major research issues in developing a model and metrics to evaluate reputation systems for file authenticity.
