A proposal for Trust-Enabled P2P Recommendation Systems

Lookup NU author(s): Dr Georgios Pitsilis, Emeritus Professor Lindsay MarshallORCiD



In this paper we present a trust-oriented solution that can be used when building Peer-to-Peer recommendation systems. We discuss its benefits in comparison to a centralized solution, its requirements, its pitfalls and how these can be overcome. In our approach, we base the formation of trust on evidential reasoning and made the proposed design with ease of adoption by existing infrastructures in mind. The paper also includes a preliminary analysis of performance based on a simple model we use to investigate the impacts on scalability and thus show the applicability of the protocol.
