p2pにおとりファイルをばら撒く技術で特許

タルサ大学教授John Haleと博士課程学生Gavin Manesがp2pにおとりファイルをばら撒いてファイル・シェアリングを邪魔する技術で特許をとった。似た技術を持っている会社は他にもOverpeerとMediaDefenderがあるが秘密主義なので詳細はわからない。

The idea behind the idea is fairly simple, and consists of flooding filesharing networks with thousands of copies of bogus files which share the same attributes as the real thing. The bogus files however contain either low quality versions of the song, advertisments for the song, or just white noise. Artists who wish to share their music over filesharing networks would not be affected as bogus versions of their music would not be created.
