This paper proposes an invertible semi-fragile video watermarking algorithm using a hash function to authenticate the video contents. It can protect the video content from malicious manipulations and detect the modified part of the video. Also the proposed algorithm has the invertible property, which allows us to get the original video data back if they are authentic.
