Abstract: It is an important problem for P2P file sharing system to limit sharing illegal contents. Maze introduces a filtering strategy based on file popularity and active peer. Simulation experiments show that the technology can decrease the download of illegal files, and save network resource consumption. It is simple but rather practical, reflecting the idea to deal with key problem first in the large-scale system.
