KDDI R&D LABS Developed New Technology for Pirated Video Detection
Saitama, Japan – October 29, 2007 – KDDI R&D LABS today announced that it has developed anew content protection technology which enables pirated video content detection bydistinguishing between the content created by a professional and the content created by anamateur.
This technology has been developed in consideration of the situation that while the number ofusers on video-sharing sites such as YouTube™ is increasing rapidly, copyrighted video clips
have been illegally uploaded, e.g. TV programs. Up to now, in order to find pirated video clips onvideo-sharing sites, a human has to check by visual inspection. Then if pirated videos are foundon the sites, copyright holders need to request the video-sharing site operators to delete them,which requires so much labor. Recently some video-sharing site operators implement a pirated
video blocker based on fingerprint, which is a set of features for identifying video content. In
fingerprinting technology, however, copyright holders have to identify copyrighted videos andprovide operators with the copyrighted videos and the necessary information, while videosharing site operators have to register fingerprints of the copyrighted videos in advance.
Moreover, it is very hard to keep following explosively increasing video clips which are newly
uploaded day after day.
KDDI R&D LABS’ technology focuses on differences between a professional and an amateur interms of their video capturing devices, their video capturing techniques, their video creation
processes, and so on. With KDDI R&D LABS’ proprietary technology, visual and audio features
which are affected by these differences are analyzed, and then it enables to distinguish between
video content created by a professional and video content created by an amateur; a very highdistinction rate of 98% is achieved. Using this technology, illegal video clips can beautomatically and reliably found on the vast amount of video content, which significantly
reduces labor costs for eliminating pirated videos. In addition, since KDDI R&D LABS’technology analyzes features of the content itself, there is no need to register pirated videos inthe database beforehand, and furthermore, it is effective for new video clips which have neverbeen uploaded so far.
This technology can be implemented as a video content inspection engine, which is installable
on video sharing servers. Upon being uploaded, a video clip will be inspected and if it issuspected as a pirated video clip, it will be rejected. This protects copyrights of video content.
