Watermarking to replace DRM?

An anonymous reader writes "News.com has an article on the announcement of Microsoft and Universal to introduce watermarking technology into audio files. The technology could serve several purposes including tracking file sharing statistics and insertion of advertisements into audio tracks. The article goes on to suggest that watermarking could possibly replace DRM in the near future."

Subtle watermarking schemes (1)

HTH NE1 (675604) | more than 7 years ago | (#20253055)

CBS has taken to blurring their HD shows briefly. I've noticed it more on CSI: Miami reruns lately (only to see them in HD). This could be a watermarking scheme or just a way to make copies made from unsecured broadcasts flawed and undesirable.

That wouldn't be much of a watermark as everyone recording the broadcast would have the same mark. You do understand that a watermark is embedded information in the file to uniquely identify the original owner of the file, right?

Depending on when the blur is applied, it could uniquely identify a broadcaster, reducing geographically the search for the infringer. (In my case, station call letters are not being superimposed on the HD feed. The station can't even superimpose local severe weather information without reverting to SD quality.)
