Abstract
A method and apparatus for enhancing encoded information through the addition of a digitally watermarked background is disclosed. The digitally watermarked background may incorporate semantic information derived from an object or further supplemental information to produce a digitally watermarked background for the encoded information. The digitally watermarked background may modify, replace, or be used in conjunction with the content of the encoded information. The digitally watermarked background may be used as a key to limit access to the information in the encoded information.

22. A method for modifying a code used for marking an object, comprising the steps of:
-
providing an intermediate transfer device adapted for carrying a digitally watermarked background;
applying a digitally watermarked background to the intermediate transfer device;
applying the intermediate transfer device to the object so as the digitally watermarked background is coexisting with the code. - View Dependent Claims (23, 24, 25, 26, 27, 28)
