Abstract. In this paper, we present a video watermarking scheme based on chaotic maps in wavelet domain. The embedding procedure is done before video compression stage. At first, we encrypt the watermark signal by a Tent map, next the encrypted watermark is embedded in HH sub-band coefficients of I-frames. This task will increase the security and resistance of our watermarking system. Experimental results verify the resistance of our proposed method against signal processing and geometric attacks. We also comprise the efficiency of our algorithm against some other methods. Comparison results show the superiority of our scheme against others.
