ABSTRACT

In this paper, we present a robust digital video watermarking technique. For robustness to geometric transformation, a watermark is embedded in the DWT domain. A watermark is created by shaping an author and video dependent pseudo-random key generation by which is formed us. As a result, the watermark adapts to each video to ensure invisibility and robustness. Furthermore, the watermark is statistically undetectable. In this method, embedded data are recovered without the original image. To robustness of the proposed method is tested by applying different types of attacks. The tests show good performances against common signal processing procedures such as noise addition, MPEG4 compression, adding mask image, Gaussian blur and scaling.
