Abstract

In Peer-to-Peer (P2P) communities, users make personal trust evaluations of each other based on their experiences and observations. The available information of the peer's past behaviour, i.e., reputation, is often incomplete, so the credibility of evaluations is a concern and the relevance of the available information varies. In this paper, we propose functions for producing tailored trustworthiness estimations in P2P communities based on the peers' past behaviour. The presented mechanism provides some flexibility for applying it to different kinds of P2P networks.
