Abstract

A document management method is disclosed. The method includes generating and merging a unique watermark for and with each page of a print job to be produced. For each watermark, data identifying the watermark is associated with data identifying a document page corresponding to the print job page with which that watermark is merged.

Claims

1. A document management method comprising:

generating and merging a unique watermark for and with each page of a print job to be produced; and

for each watermark, associating data identifying the watermark with data identifying a document page corresponding to the print job page with which that watermark is merged.

2. The method of claim 1, further comprising identifying a user responsible for the document and associating data identifying the user with the data identifying the watermarks.

3. The method of claim 1, further comprising processing the print job to produce a document having one or more document pages, each document page including the watermark merged with the print job page for that document page.

4. The method of claim 3, further comprising maintaining status data for each document page, the status data for each document page being associated with the data identifying that document page'"'"'s corresponding watermark.

5. The method of claim 4, wherein the status data associated with a given document page at least indirectly indicates whether or not that document page has been destroyed, copied or otherwise acted upon.

6. The method of claim 4, wherein maintaining comprises updating the status data for a given document page upon a determination that an operation has been or will be performed with respect to the document page.

7. The method of claim 1, further comprising:

processing the print job to produce the document, each document page including the watermark merged with the print job page for that document page;

recognizing the watermark included on the selected document page;

identifying an operation performed on the selected document page; and

associating status data with the data identifying the watermark included on the selected document page, the status data identifying the operation performed on the selected document page.

8. The method of claim 7, wherein identifying an operation comprises identifying that the selected document page has been or will be destroyed, copied, or otherwise acted upon.

9. The method of claim 7, wherein identifying an operation comprises identifying that the selected document page has been or will be copied.

10. A document management method, comprising:

recognizing a watermark included on a selected document page;

performing an operation on the selected document page; and

associating status data with data identifying the watermark included on the selected document page, the status data identifying the operation performed on the selected document page.

11. The method of claim 10, further comprising repeating the acts of recognizing, performing, and associating for each page in the document.

12. The method of claim 10, wherein performing an operation comprises producing a copy of the selected document page, wherein recognizing includes digitizing the selected document page, the method further comprising:

generating and merging a new watermark with the digitized document page;

associating data identifying the new watermark with data identifying the copy of the selected document page; and

wherein producing a copy comprises processing the digitized document page merged with the new watermark to produce the copy of the selected document page.

13. The method of claim 12, further comprising removing the recognized watermark from the digitized document page.

14. The method of claim 12, wherein generating comprises modifying the recognized watermark to generate the new watermark.

15. A computer readable medium having computer executable instructions for:

generating and merging a unique watermark for and with each page of a print job to be produced; and

for each watermark, associating data identifying the watermark with data identifying a document page corresponding to the print job page with which that watermark is merged.

16. The medium of claim 15, having further instructions for identifying a user responsible for the document and associating data identifying the user with the data identifying the watermarks.

17. The medium of claim 15, having further instructions for processing the print job to produce a document having one or more document pages, each document page including the watermark merged with the print job page for that document page.

18. The medium of claim 17, having further instructions for maintaining status data for each document page, the status data for each document page being associated with the data identifying that document page'"'"'s corresponding watermark.

19. The medium of claim 18, wherein the status data associated with a given document page at least indirectly indicates whether or not that document page has been or will be destroyed, copied, or otherwise acted upon.

20. The medium of claim 18, wherein the instructions for maintaining include instructions for updating the status data for a given document page upon a determination that an operation has been or will be performed with respect to the document page.

21. The medium of claim 15, having further instructions for:

processing the print job to produce the document, each document page including the watermark merged with the print job page for that document page;

recognizing the watermark included on a selected document page;

identifying an operation performed on the selected page; and

associating status data with the data identifying the watermark included on the selected document page, the status data identifying the operation.

22. The medium of claim 21, wherein the instructions for identifying an operation performed include instructions for identifying that the selected document page has been or will be destroyed, copied, or otherwise acted upon.

23. The medium of claim 21, wherein the instructions for identifying an operation performed include instructions for identifying that the selected document page has been or will be copied.

24. A document management system, comprising:

a watermark generator operable to generate and merge a unique watermark for and with each page of a print job to be produced; and

a data manager operable, for each watermark, to associate data identifying the watermark with data identifying a document page corresponding to the print job page with which that watermark is merged.

25. The system of claim 24, further comprising a user authenticator operable to identify a user responsible for the document and wherein the data manager is operable to associate data identifying the user with the data identifying the watermarks.

26. The system of claim 24, wherein the data manager is operable to maintain status data for each document page, the status data for each document page being associated with the data identifying that document page'"'"'s corresponding watermark.

27. The system of claim 26, wherein the status data associated with a given document page at least indirectly indicates whether or not that that document page has been or will be destroyed, copied, or otherwise acted upon.

28. The system of claim 26, wherein the data manager is operable to update the status data for a given document page upon a determination that an operation has been or will be performed with respect to the document page.

29. The system of claim 24, further comprising:

a scan engine operable to digitize at least a portion of a selected document page;

a watermark reader operable to recognize the watermark included on that document page; and

wherein the data manager is operable to associate status data with the data identifying the watermark included on the selected document page, the status data identifying an operation that has been or will be performed on the selected document page.

30. A document management system, comprising:

means for generating and merging a unique watermark for each page of a print job to be produced; and

means for associating, for each watermark, data identifying the watermark with data identifying a document page corresponding to the print job page with which that watermark is merged.
