In this paper, we propose a DWT-based video watermarking algorithm applying DS-CDMA (Direct Sequence Code Division Multiple Access). We use improved Gold sequences to encode the watermark. The CDMA encoded watermark is embedded into the lowest frequ

A robust image watermarking scheme in which a binary image is embedded in the singular values of selected DWT blocks in the horizontal and vertical sub-bands of a 1-level decomposition of a gray-scale image is proposed. The embedded blocks are selec
