摘要：During the past decade, with the development of information digitalization and internet, digital media increasingly predominate over traditional analog media. However, as one of the concomitant side-effects, it is also becoming easier for some individual or group to copy and transmit digital products without the permission of the owner. The digital watermark is then introduced to solve this problem. Based on DWT and SVD a new watermarking algorithm is proposed. The proposed method satisfies the imperceptibility and robustness and some common attacks very well. And the algorithm is robust to the common image process such as JPEG compression,, rotating, cutting, and contrast enhance. Compared with the SVD, the proposed algorithm is DWT+SVD has stronger robustness and faster speed in embedding and extracting.
