This reliable automatic detection system will assist companies in making cost savings by identifying, confirming and tracking non-authentic video film exchange over the Internet. Videos that are copied across peer-to-peer networks can be substantially altered. For example changes in spatial resolution, CODECS, colour depth and frame rates all increase the difficulty of retrieving a watermark for identification. This technology does not embed additional information in the video and automatically identifies computer derived/digital files containing copies of videos and movies. The performance is independent from CODEC, low bitrate, low frame rate, and noise artefacts.
