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.
Claims30
A method for marking an object, comprising:
- producing a digitally watermarked image;
- and,
- applying the digitally watermarked image onto the object so as to be coexisting with a code, thereby forming a digitally watermarked background image.
A marking for identifying an object, comprising:
- a digitally watermarked background adapted for use with a code, a manifestation of the code coexisting with the digitally watermarked background upon the object.
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.
An apparatus for reading a digitally watermarked background, the apparatus comprising:
- a portable device comprising at least a digital camera, memory and a microprocessor;
- and at least one digital watermarking algorithm stored in the memory, the algorithm adapted for decoding of at least one digital watermark in an image comprising a digitally watermarked background to a coexisting code.
A method for reading a digitally watermarked background, the method comprising:
- providing a portable device comprising at least a digital camera, memory and a microprocessor;
- and at least one digital watermarking algorithm stored in the memory, the algorithm adapted for decoding of at least one digital watermark in an image comprising a digitally watermarked background to a coexisting code;
- collecting an image of a code with a coexisting digitally watermarked background;
- and,
- decoding information contained in the digitally watermarked background.
