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.

Keywords: trust; reputation management; peer-to-peer; P2P networks; tailored trustworthiness; trustworthiness estimations; evaluation credibility; past behaviour.
