Substituting information based on watermark-enable linking
First Claim
1. A method to provide substitute data for original data found in a printed document, the substitute data being provided in a copy of the printed document, wherein the printed document comprises steganographic indicia including an identifier, said method comprising the steps of:
- receiving optically captured data corresponding to at least a portion of the printed document;
analyzing the optically captured data to obtain the identifier;
communicating with a data repository, the data repository including the substitute data, wherein the substitute data is identified at least in part by the identifier;
receiving the substitute data from the data repository; and
when generating a copy of the printed document, substituting the substitute data for the original data.

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.

14. A method to obtain a relatively higher quality object from a data repository, the relatively higher quality object corresponding to an original object found in original media, the original media comprising a digital watermark embedded therein, wherein the digital watermark includes a message, said method comprising the following steps:
-
decoding the digital watermark from data corresponding to the original media to obtain the message;
by using at least the message, instructing the data repository to provide the relatively higher quality object; and
after receiving the relatively higher quality object, replacing the original object in a copy of the original media with the relatively higher quality object. - View Dependent Claims (15, 16, 17, 18, 19, 24)

20. A method to provide substitute data for original data found in a document, wherein the document comprises a digital watermark including an identifier, said method comprising the steps of:
-
analyzing the document to obtain the identifier;
requesting from a data repository the substitute data, wherein the substitute data is stored within the data repository, and wherein the substitute data is associated with the identifier;
receiving the substitute data from the data repository; and
substituting in the document the substitute data for the original data. - View Dependent Claims (21, 22, 23)

25. A method to provide substitute data for original data found in media, wherein the media comprises a first digital watermark including a first identifier, and a second digital watermark including a second identifier, wherein the first identifier corresponds with first original data, and the second identifier corresponds with second original data, said method comprising:
-
analyzing the media to obtain the first identifier and the second identifier;
requesting the substitute data by using at least the first identifier and the second identifier, wherein the substitute data comprises first substitute data corresponding with the first original data and second substitute data corresponding with the second substitute data;
receiving the substitute data; and
substituting the first substitute data for the first original data and the second substitute data for the second substitute data. - View Dependent Claims (26)

27. A method to provide a user with an option to substitute data for original data found in media, wherein the media comprises machine-readable indicia including an identifier, said method comprising:
-
machine-reading the media to obtain the identifier;
obtaining substitute data corresponding to the identifier; and
providing an option to a user to determine whether to substitute the substitute data for the original data. - View Dependent Claims (28, 29, 30, 31, 32)

33. A method to substitute data for original data found in media, wherein the media comprises a digital watermark embedded therein, said method comprising:
-
analyzing the media to recover the digital watermark;
requesting from memory data to substitute for original data found in the media, wherein the data to substitute for the original data is associated with at least a portion of the digital watermark;
receiving the data to substitute for the original data from the memory; and
substituting in the media the data for the original data.
