Practical, Anonymous, and Publicly Linkable Universally-Composable Reputation Systems
Johannes Blömer, Fabian Eidens, and Jakob Juhnke
Abstract
We consider reputation systems in the Universal Composability Framework where users can anonymously rate each others products that they purchased previously. To obtain trustworthy, reliable, and honest ratings, users are allowed to rate products only once. Everybody is able to detect users that rate products multiple times. In this paper we present an ideal functionality for such reputation systems and give an efficient realization that is usable in practical applications.
