Digital fingerprinting to ID copyrighted material

Shelly Palmer:

NIELSEN has partnered with DIGIMARC to create a service that both watermarks and fingerprints digital content, allowing it to be tracked across the web. Fingerprinting will be done by matching the audio track of a video to known content in the Nielsen database while watermarking will embed content information (such as when a show first aired). The service, called Digital Media Manager, will help video-sharing sites identify copyrighted material and apply rules established by the content owner. It is expected to launch this spring.
