Watermark-based object linking and embedding
First Claim
1. A system for producing an enhanced digital object comprising:
- a source of original object data;
a watermark detector; and
a data structure including a source of substitute data, the source of substitute data including at least one substitute object component that corresponds to a component found in the original object data;
the aforesaid elements cooperating to permit substitution of the substitute object component for the original component found in the original object data by reference to watermark data encoded in the original object component, the watermark data being decoded by said watermark detector.

Abstract
OLE-like principles are implemented using watermark data in digital objects in order to effect object linking or embedding. In one embodiment, a photocopier scans an original paper document to produce image data. This image data is analyzed for the presence of watermark data identifying a graphic on the document. With this watermark identifier, the photocopier can query a remote image database for pristine image data corresponding to the scanned graphic. This pristine data can be relayed from the remote database to the photocopier and substituted into the scanned image data. Output printed from the photocopier is thus based, at least in part, on pristine image data, rather than on image data that has been subjected to various corruption mechanisms (e.g., degradation of the original paper document, artifacts due to scanning, etc.). A “photocopy” better than the “original” can thereby be achieved.

5. A method of enhancing an original digital object comprising:
-
recognizing a component of the original digital object having a watermark encoded therein;
by reference to the watermark, obtaining a counterpart to the component from a data repository, the data repository including at least the counterpart, wherein the counterpart corresponds to the component; and
substituting the counterpart for the component in the original digital object to produce an enhanced object. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
