Copyright infringements and data piracy have become serious concerns for the ever growing online video repositories in recent years. The uploaded videos on commercial sites are mainly textually tagged. Tags are of little help in monitoring the content and preventing copy-right infringements. The watermarking approach and the fingerprinting approach have been used for detecting such infringements, however, there is still the need for fast algorithms for duplicate detection in large databases.
Researchers at UCSB have developed a fast and accurate method for detection of duplicate videos in a large database. This can be used to detect the presence of copyrighted videos in the database. The method uses very compact yet sufficiently discriminative signatures called video 'fingerprints'.
