TorrentSpy begins weeding out copyright content

TorrentSpy, the torrent-file search engine accused by Hollywood of aiding copyright violators, plans to remove links from its search results to pirated content using a new filtering system.

FileRights is an automated filtering system created by some of TorrentSpy's founders. The technology uses "hash" values to automatically remove links to infringing works from search engines that subscribe to the service.

In an interview, Rothken acknowledged that using hash marks to identify copyright content is not foolproof. If a file is altered then the system may not recognize it.

Filtering doesn't necessarily mean an end to the hostilities between Hollywood and the torrent search engines. In 2001, file-sharing system, Napster, launched a filtering system that failed to thwart illegal file sharing enough to satisfy the music industry or the courts.

FileRights works like most video filters. Copyright owners handover information about their films or TV shows and the system detects any files containing unauthorized copies. Links to those files are automatically removed.

Any copyright owner, Web site or search engine is welcome to subscribe to the service for free, according to the company's statement. According to Rothken, one of TorrentSpy's competitors, IsoHunt, has agreed to use the filtering system as well.
