Digital image watermarking is a useful solution to the problem of information security, copyright and network security. In this paper, a new watermarking algorithm is propose based on Singular Value Decomposition (SVD) and discrete wavelet transform (DWT). The algorithm uses a gray image as a watermark, increasing embedded information capacity. The algorithm can satisfy the transparence and robustness of the watermarking system very well. The experimental result based on this algorithm have shown that the watermarking is robust to the common signal processing techniques including JPEG compressing, adding noise, low pass filter, median filter, cropping and so on.
