The Content-ID system is Google&s method to prevent unauthorized uploading of video and audio material to YouTube, or to give rights holders the opportunity to take action against rights violations. The system mainly works automatically by matching user clips with content in a database of protected content -- if a match is found, a claim is made and the video is either blocked or, more often, monetized for the benefit of the rights owner.
However, it is also possible for rights owners to make manual claims to specific videos after performing their own search, provided they are content ID partners. For such claims, Google is now changing the procedure a little to make it easier to fix the copyright infringement. As it already happens with the automatic procedure, the exact, objectionable position in the video must be indicated by a time stamp so that the user can then remove it using Youtube&s own editing tool, which also appears to have been revised. Alternatively, the audio track can be deactivated at this point or another music deposit can be selected. If the section in question has been edited in the clip, the claim is automatically removed again.
So far, so good -- but the Content-ID also has some weaknesses. For example, labels or artists often have songs protected as their own works, even though they are only derivatives of freely available songs. Unfortunately, it happens to us again and again that a music track released under a CC license, which we have used in a test clip, is suddenly complained years later as copyright infringing, because some musician simply sings his lyrics over it and - erroneously - completely claims the result as his own creation. Then any other use of the original piece is prevented by content ID recognition. Elsewhere, we had already described from our own experience how in such a case objection to the claim can be raised.
An automatic copyright protection system would therefore be optimal, in which it would actually be checked whether the right claim is at all given -- optimal, but hardly feasible.
