Abstract

Digital Watermarking is a process of embedded data for copyright protection and authentication. This paper proposed a digitally invisible watermarking algorithm in video sequence by means of Discrete Wavelet Transform (DWT) and Discrete Cosine Transform (DCT). To improve the security, we used chaotic map for embedding position of a watermark. A watermark, binary image, was embedded in a selected sub-band. The experimental results show this algorithm is more robustness to attacks and can achieved copyright protection/authentication.
