This paper proposes a color image digital watermarking method based on valve-value surface. First it builds the valve value of curve surface of the original image to get the outline information of the original image; then it embeds watermarks into the edge of the outline. Because the function used by the method to build valve-value surface has high gliding property and easy interpolation ability, the method has strong resistance to attacks like filtering and zooming. Experimental results indicate that detection in the LL band is robust for one group of attacks, and detection in the HH band is robust for another group of attacks.
