摘要：This paper proposes a new fragile video watermarking algorithm based on motion vector, we first use the frame difference method to detect moving targets, determine the motion macro blocks. Then in the macroblock by the diamond search, the fragile watermark is embedded in the P-frame motion vectors for inter prediction, so that by changing the mapping of pixel precision motion vector is to be embedded watermark information embedding watermark information. Experimental results show little effect on the video quality of the algorithm.
