Abstract :
Frame tampering is one of the common video forgery operations, which can change the video content and confuse the viewers by removing or inserting some special frames in the video streams. In this paper, a new method is proposed to detect this kind of tampering based on the features of the power of high frequency area in the doctored sequences. Experiment results demonstrate that our proposed method can effectively detect frame tampering in the MPEG-2 streams.
