Japan’s NEC has developed a technology that can find illegal copies of videos uploaded to the Internet in seconds. This speed is attained by creating a comparison piece that is just 76 bytes from the original and compares it to the allegedly copied file. The technology is part of the MPEG-7 standard, and would help movie producers and Internet service providers identify pirates both faster and more accurately than in the past.

NEC says its technology has a 96 per cent success rate and a false alarm rate of 5 in one million under tests conduced by the ISO. It can accurately detect the validity of a video from a two-second, 60-frame snapshot. NEC maintains that an average home PC with a single-core 3GHz chip can match 1,000 hours of video in one second.
