摘要We present a video watermarking scheme which is robust to video coding standards H.264. The proposed scheme embeds watermark on all AC coefficients of 4×4 DCT blocks of I-frames. It integrates Watson's human visual system and the contents of 4×4 DCT blocks to determine the embedding strength. Since the high correlation of the video content within one scene, producing similar embedding strength, the scheme has the property of same watermarks for same scenes and different watermarks for different scenes. Thus, it can successfully resist the collusion attacks. Experiments validate that the proposed scheme has advantage of the invisibility, and it is robust to collusion attacks as well as H.264 compression.
