A novel blind watermark algorithm based On SVD and DCT

In this paper, we propose a blind watermarking algorithm for digital image based on DCT and SVD. The algorithm can satisfy the transparence and robustness of the watermarking system very well. The experiment based on this algorithm demonstrates that the watermarking is robust to the common signal processing techniques including JEPG compressing noise, low pass filter, median filter, geometric cropping and contrast enhance.
