In this paper, a method of embedding a digital watermark into an image is proposed. By taking advantage of zerotree in the rearranged DCT coeffcients for watermarking, the algorithms can extract the watermark without original image. To enhance the robustness of watermarking, the watermark information is coded by error correction coding of Hamming code in our algorithm. Experimental results show that the proposed techniques successfully survive some image processing operations and the lossy compression techniques such as Joint Photographic Experts Group (JPEG).
