A new algorithm of image watermarking based on SVD is presented.Watermark image is firstly permuted with Arnold trans-formation.According to two different values of watermark image,two random sequences is embeded into singular values of every block.Experimental results demonstrate that the watermark is invisible and robust against common signal processing.When extracting water-mark,it does not need the original cover image but two secret keys.
