H. 264 video standard based zero watermarking technology

Combined with the H.264/AVC video encoding standard, a new digital video watermarking technology - zero watermarking technology was proposed in the paper. It breaks traditional idea of digital watermarking technique; the important characteristics of video data were used to construct the watermark information. In this paper we construct zero watermark information based on the characteristics of DCT quantization coefficients by intra-prediction. The algorithm is not only real-time but also simple and efficient. Experimental results show that the constructed watermark information had ability of unique identification the host media and robustness against a variety of tampering attacks. And it also can reduce the impact of interpretation attacks by introducing the time-stamp mechanism.
