Article Preview

This paper introduces a digital watermark algorithm based on H.264. This algorithm controls the DCT coefficients for 4X4 block to resist the attack. Through the experiment results, under the condition of no obvious increase in complexity and no obvious change of PSNR, BITRATE changes in less than 5%.The attack on level can be 98% detected with omission factor under 2% and no fallout ratio.
