    摘要: Various exemplary embodiments disclose an apparatus and method for generating a database that maps metadata to peer-to-peer (P2P) content and, more particularly, to a database that an Internet Service Provider (ISP) can build to correlate metadata with P2P traffic. The database may collect metadata having a key that uniquely corresponds to particular P2P content. An ISP may use the database to identify malware in P2P files and tag P2P traffic that seeks to exchange material in violation of applicable copyright laws.
