In peer-to-peer (p2p) systems, work is distributed among the participating peers, unlike the classical client-server architecture, where work is done by a central server. One of the fundamental problems facing p2p systems is that different peers may have different interests: in extreme cases, some peers may even wish to destroy the usability of the system. It is therefore necessary to develop a (possibly implicit) notion of trust, so as to allow peers to continue functioning in the face of diverse, potentially hostile peers. In this talk I will describe a line of recent research which studies the algorithmic aspect of concepts such as "trust," "collaborative filtering" and "recommendation systems."
