Abstract	A new digital image watermarking algorithm based on texture block and edge detection in the discrete wavelet domain is proposed in order to balance between the invisibility and robustness and improve the ability of resisting to geometric attacks of the digital image watermark. In the algorithm, the texture blocks are extracted after the edge detection for the original image with the canny operator by using the masking property of human visual system, in which the watermark is embedded adaptively both in the low-frequency sub-band and the high-frequency sub-band in the discrete wavelet domain. The experiment result shows the watermark has good invisibility and robustness as well as the ability of resisting to geometric attacks by using the algorithm proposed in this paper. At the same time, three keys generated in the embedding process that can raise the security of the watermark.
