  text: Reputation systems are used to compute and publish reputation scores for services
    or products. We consider reputation systems where users are allowed to rate products
    that they purchased previously. To obtain trustworthy reputations, they are allowed
    to rate these products only once. As long as users rate products once, they stay
    anonymous. Everybody is able to detect users deviating from the rate-products-only-once
    policy and the anonymity of such dishonest users can be revoked by a system manager.
    In this paper we present formal models for such reputation systems and their security.
    Based on group signatures presented by Boneh, Boyen, and Shacham we design an
    efficient reputation system that meets all our requirements.
