Multilateral Secure Cross-Community Reputation Systems for Internet Communities
The Internet gives people various possibilities to interact with each other. Many interactions need trust that interactors behave in a way one expects them to do. If people are able to build reputation about their past behaviour this might help others to estimate their future behaviour. Reputation systems were designed to store and manage these reputations in a technically efficient way. Most reputation systems were designed for the use in single Internet communities although there are similarities between communities. In this paper we present a multilateral secure reputation system that allows to collect and use reputation in a set of communities interoperable with the reputation system. We implemented our system for the community software phpBB.
