Abstract :
Previous research [1] has indicated that reputation scores can be used as the basis for trust computation in P2P networks. In this paper, we use reputation scores calculated from P2P search engine rating sites to determine whether a torrent is likely to be linked to a fake file (or not). Our results indicate clear separability between files which are fake and which are genuine, assuming the integrity of the "community" ratings provided by specific subcultural groups [2]. Suggestions for more sophisticated reputation-based scoring are also provided.
