Abstract :
In this paper, a DWT-based video watermark algorithm has been proposed to carry on three-DWT to the video frame after the scene analysis, the using of genetic algorithm to insert the watermark image that has been scrambled by Arnold scrambling algorithm ensures the hidden data visually invisibility. Blind watermark algorithm is used when it extracts watermark image. The experimental results illustrate that the proposed watermarking algorithm is robust to video degradation attacks, such as noise, MPEG coding , frame dropping and frame swapping.
