TorrentFreak has learned that one of the anti-piracy strategies developed by the company uses the social profile information of Facebook users and their connections to others as a factor in determining whether a shared file is copyright-infringing or not. Facebook was granted a patent for its invention today, but it’s not known whether the technology is already being used on a wide-scale.
The patent in question is named “Using social signals to identify unauthorized content on a social networking system” and in the introduction Facebook describes the wealth of personal and social information the company can tap into.
“”[...] users have been voluntarily divulging more of their personal information, such as their friends, geographic location, preferred television shows and movies, hobbies, and activities to social networks,” Facebook notes, adding that they can also see who people communicate with and who they are connected to.
