YouTube, Fingerprinting and Crippleware

Here's an entry outlining YouTube's new approach to infringing content:

Some of its mechanisms include removing the embed codes from the infringing page, and directing users to the copyright owner's own version of the work.

It's unclear as to the level of sophistication of YouTube's fingerprinting capabilities, though the article suggests they're working with Audible Magic:

The comments also provide a sample of the infringement notification sent by YouTube:

Dear YouTube Member:

Sony/BMG has claimed some or all visual content in your video Float On. This claim was made as part of the YouTube Content Identification program.

Your video is still live because Sony/BMG has authorized the use of this content on YouTube. As long as Sony/BMG has a claim on your video, they will receive public statistics about your video, such as number of views. Viewers may also see advertising on your video's page.

Sony/BMG claimed this content as a part of the YouTube Content Identification program. YouTube allows partners to review YouTube videos for content to which they own the rights. Partners may use our automated video / audio matching system to identify their content, or they may manually review videos.

Sincerely,
The YouTube Content Identification Team
