Copied video detection with MPEG-7 video signature and multiple direct-mapped cache


According to the increasing popularity of video-sharing websites, copyright infringed videos have become a critical issue. These videos are not only original ones, but also copied ones. Under these circumstances, the importance of video detection technology has increased. In our earlier studies, we had proposed the (single) direct-mapped cache method based on the RGB color space feature to handle the processing of a large amount of videos on the Internet. Although our method achieved a high processing speed, the detection accuracy had room for improvement. In this paper, we proposed a new method to improve the accuracy. For this purpose, the combination of MPEG-7 video signature and the multiple direct-mapped cache method is used. The experimental results show that the average detection accuracy is 95%, and the processing time is 0.2 seconds for each video. These results indicate a 29% improvement in accuracy over the previous method. The possibility of handling 136 years worth of video data while keeping the same accuracy and processing speed is also one of the unique features of the proposed method.
