Deepfake is a kind of technique which forges video with a certain purpose. It is in urgent demand that one approach can defect if a video is deepfaked or not. It also can reduce a video to be exposed to slanderous deepfakes and content theft. This paper proposes a useful tool which can encrypt and verify a video through proper corresponding algorithms and defect it accurately. Experiment in the paper shows that the tool has realized our goal and we can put it into practice.
