Blind shot-based watermarking of RGB video stream in the wavelet domain

In this paper a new video watermarking scheme is proposed which depends on 2-level DWT decomposition of each component of RGB components in each frame. The scheme embeds independent watermarks into different shots. The matching between shots and watermarks is based on GA. The scheme chooses between HL1 of red or green or blue components of each frame based on a key and embeds error correcting code into one of them. The scheme is blind. Experimental results shows that the scheme is robust against attacks such as frame dropping, frame averaging, frame swapping, statistical analysis, and MPEG-2 and MPEG-4 compression. The proposed scheme uses two keys to increase the security.
