Abstract

In this paper, a fragile watermarking algorithm for H.264/AVC compressed video using CAVLC mapping is proposed. By extensive analysis with several video sequences, we observed that not all code words appear in the bit stream. Watermark bits can be embedded by mapping used CAVLC code words to unused code words. During the embedding process, the eligible code words are first identified, and then the mapping rules between these code words and the watermark bits are established. The watermark information can be extracted directly from the encoded stream without resorting to the original video, and merely requires decoding the CAVLC code from bit stream rather than decoding the whole video. Experimental results show that the proposed watermarking scheme can effectively embed information with little bit rate increase and almost no quality degradation.
