In this paper, a highly robust digital video watermarking technique is given. First of all, the watermark information is encrypted by Arnord transform. Then it is embedded in DCT domain by high-frequency coefficients correlation algorithm in RGB frames of source video file. The field tests indicate that the video file with the watermark information is transparent, and strong anti-aggressive.
Most of attacks in video digital watermarking are synchronization attacks. They can be classified as temporal and spacial synchronization attacks after characteristics of video digital watermarking are analyzed. Then synchronization robustness can be divided into inter-frame robustness and intra-frame robustness according to classifications of synchronization attacks in video digital watermarking,...
