Video Fingerprinting Overview: Who's Doing What (blog post)

The New York Times dubs it "content-recognition software"; others call it video fingerprinting. The idea is to create a kind of digital dragnet that would allow copyright owners to prevent snippets of their work from being uploaded to video-sharing sites, or circulated around the Net.

Who's developing this technology? Here's my short list:
- Advestigo (FT article ... NewTeeVee)
- Attributor (WSJ article)
- Audible Magic (Post-Gazette.com ... AP article)
- Gracenote
- GUBA's Johnny (Broadcasting & Cable article ... TechCrunch posting)
- Philips (PC World article ... Philips explainer)
- YouTube
