An MPEG-4 Motion Vector Watermarking Scheme Based on Scrambling Using Game of Life
Long Tang · Acta Scientiarum Naturalium Universitatis Sunyatseni · 2004
A video watermarking scheme for the motion vector of MPEG-4 video object is proposed. Via operating the compressed video data stream directly, the permutated watermark is embedded into the motion vector indicators. Therefore, the scheme has a good compatibility with the compression standard. Experimental results show that the proposed algorithm is considerable simple and efficient,and PSNRs of watermarked frames are reduced rather slightly. In addition, the scheme employs the noninvertible life-game scrambling to resist the protocol attacks.
