New NEC technology captures illegal video copies on Internet in seconds
NEC corp. announced today the development of a new technology that is capable of accurately detecting the illegal copies of video contents or their altered versions uploaded to the internet in just a few seconds. Apparently it can manage to do so by generating a compact signature or fingerprint of 76 bytes of size per frame of the original content and comparing them with the video content on the internet. That means, for instance, any screener or camcorder movie copies will be detected by either the producers or service providers fast and easy.
And according to the NEC, the technology succeeded %96 of detection rate with low false alarm rate of 5ppm (5 in one million) during the tests conducted by international standardization organization (ISO). And the technology is already accepted as part of the MPEG-7 standard.
