ABSTRACT:
The present invention provides techniques to steganographically mark specular surfaces. In one implementation, we steganographically mark a specular surface by providing a steganographic signal including at least plural-bit data, and arranging ink in a pattern on the specular surface to represent the steganographic signal. The ink preferably provides a diffuse reflection property.
