Abstract: This paper analyses the problem of file pollution on P2P file sharing networks, presents various kinds of pollution techniques, and puts forward possible counter-measures to them. In particular, a novel cooperative “warning-delete” approach is proposed to alleviate the most serious version pollution. The effectiveness of this approach is proved by simulation experiments.
