In this paper,we present an anti-pollution mechanism based on the maximum entropy to collaborative filtering of file-pollution in P2P networks.First,making use of visiting record with time parameter,it describes the change of files context and then proposes the filtering way of files.Through adding the maximum entropy model to the model,the dynamics of files context was reflected.Furthermore,it can effectively stop the polluted files from prorogating in the networks.The simulation result shown that the model has good performance and robustness.
