Fragile Video Watermarking Technique by Motion Field Embedding with Rate-Distortion Minimization
Tien-Ying Kuo, Yi-Chung Lo, Chen‐I Lin · 2008
In this paper, we proposed a fragile video watermarking technique to authenticate the H.264 video content. Watermark information is embedded in motion vectors which have fragile nature. The proposed method finds out the best locations of motion vectors to embed the information to achieve the fragility, where are based on the statistical analysis of the motion vector by the H.264/AVC Rate-Distortion cost function. This scheme does not need the original video sequence for watermark detection. Experimental results show that the proposed watermarking technique can keep the perceptual quality at best effort and still has good fragility.
