Abstract
Digital watermarking is one of the effective methods which can protect the copyright of multimedia data. This thesis presented a digital watermarking technology based on Arnold and DCT techniques. To improve the robustness of watermark, this thesis adopted the multi-embedded strategy. The DC coefficients in the block of the same location of each color components, are embedded the same robust watermark. The robust watermark is a binary copyright image being transformed by Arnold. The results show that, the proposed watermarking algorithm is an effective way to identify the copyright of image.
