Only if you knew that was already going on. Security by obscurity, but still, I don't believe this kind of watermarking was ever used.
Maybe something like Cinavia[1] could be used instead? It's an analog watermarking system for detecting pirated copies and refusing to play them if player detects such copy is played on something else than bluray disc. Apparently this survives transcoding, and was/is major pain for people ripping their discs for various reasons and trying to play the files on certified players.

- zapu 12y agoStill, we are talking about one-shot solutions for big events, like this Game of Thrones release. Obviously I can come up with anything and you would be able to present a strategy how to beat it. But that's not the point. If this kind of various copyright protections become norm, people might actually be afraid to leak stuff, because you will never know how safe it is and what kind of protection you might run into. Even after analyzing spectrogram and generally watching the media multiple times, trying to find anything weird. Well, obviously when you grab infinite number of watermarked copies, you might be able see where the irregularities are. But that's not how leaks happen.
