Here’s the official statement from Official Google Blog about the state of YouTube’s video ID tool, an issue which received some media buzz the past couple of days.
“We are beginning tests on an automated system to identify and match specific videos. The technology extracts key visual aspects of uploaded videos and compares that information against reference material provided by copyright holders.”
The statement further clarifies that although the technology may be in place and actually work, but still, it may not be the most effective method of stopping copyright infringement on video contents uploaded in YouTube. The same is true for identifying and pulling out of pornographic materials.
The bottomline still is not how good the technology is, but how concern YouTube users are in ensuring that the YouTube community is always populated by clean user-generated videos only.
