To deal with the file pollution problem in unstructured P2P file sharing systems, an anti-pollution strategy based on field theory is proposed. Based on the management of pollution degree, a pollution field is constructed, which is composed by pollution slicks. In order to reduce the impact on user experience while curbing the propagation of polluted files, classification management is achieved by applying different punitive measures to peer in different pollution slick. The experimental results show that this strategy can curb the propagation of polluted files quickly.
