Following a test of the system earlier this year, YouTube has finally launched a beta version of a copyright identification and filtering system. The company, on its blog, says the system will allow copyright holders to identify when their work is uploaded on YouTube, at which point they can choose to have the content blocked, promote the video further on the YouTube site, or receive a share of ad-revenue for each time the clip is viewed.

It uses a combination of software created internally by Google as well as filtering technology from Audible Magic. It won't block content from being uploaded, but instead will create rules around content after users post it.

Participating entertainment companies will need to provide YouTube with full copies of all their copyrighted content for the system to work.
