| Abstract | ||
| This paper is directed toward the task of embedding a robust invisible watermark in the found sprite object (survive object) in each Group of Video (GOV). The proposed system is designed to provide authentication and protection to video by embedding invisible watermark. Three different watermark data embedding methods have been developed and used; they are: (i) Blocks average modulation applied on RGB domain, (ii) Blocks average modulation applied on Y-band only, and (iii) Haar wavelet approximation modulation. Uniform quantization is used as part of hiding step for modulating the block mean value of one or more of the color bands. The conducted tests indicated that the proposed block mean modulation method in the Y-subband of sprite blocks offer excellent robust watermark embedding; it was capable to withstand against lossy JPEG and JPEG2000 compression attacks. | ||
