To further prevent copyright infringement, NEC has developed a new tool that can analyze about 60 frames or two seconds of video and will determine if the content is pirated.

NEC said the software has a 96% accuracy rate or false alarm rate of 1 in 200,000.  The technology works by generating a compact signature (about 76 bytes per frame) and compares it to a signature of the original.  It can even detect alterations to the original when subtitles are added or added languages.

The average single core PC could analyze up to 1,000 hours of video in as little as one second.  Thats pretty darn fast!

NEC hopes its anti-piracy software will reduce the time, cost, and inaccuracy associated with manually seeking out illegal videos online.
