Watermarking Movies

NAB Update - March 3, 2005:

"At NAB2005, NEXTAMP will unveil a system to secure HD and SD digital master copies. The content protection solution relies on patented Video Watermarking technology to thwart movie piracy. Individual copies of dailies, masters and browsing versions of a movie can now contain an invisible digital watermark ID to dissuade the recipients from pirating content. This invisible stamp is robust to compression, conversion and resolution changes.

The ID can be retrieved from any pirate sample (e.g. a DivX type file on the Internet or a black market DVD).

A “virtual barcode” is embedded in the essence of the video. This invisible stamp can then be read whatever the video editing and format changes. Any video sequence can be traced back to its source.
