The Application of Semi-fragile Digital Watermark Technology in the MPEG
Xiaohui Duan · Acta Scientiarum Naturalium Universitatis Sunyatseni · 2004
Based on the MPEG_2 video coding standard, some watermark arithmetics used in static image process are introduced to the video watermarking. And the goal is achieved that not tampering with the video quality at the same time of according with the MPEG_2 coding standard, and being tolerant of the transmission distortion and normal image/video processes as well as detecting some intended attacks and sophistication. In addition a digital watermark authentication arithmetic aimed at the MPEG standard is proposed.
