%X Content based video forensics is an effective technictue to detect the legality of video content Nowadays, it has been a hot in the research field of multimedia security. I3y taking advantage of video fingerprint, this technique can extract varieties of visual features from illegal videos as evidence. In a typical video forensics model,the process of fingerprint extraction consists of shot segmentation, key frame extraction and fingerprint extraction. Thus, this paper analyzed content-based video forensics technique from these three aspects, and introduced the research development of the related algorithms.
