Abstract

A trusted rendering system for use in a system for controlling the distribution and use of digital works. A trusted rendering system facilitates the protection of rendered digital works which have been rendered on a system which controls the distribution and use of digital works through the use of dynamically generated watermark information that is embedded in the rendered output. The watermark data typically provides information relating to the owner of the digital work, the rights associated with the rendered copy of the digital work and when and where the digital work was rendered. This information will typically aid in deterring or preventing unauthorized copying of the rendered work to be made. The system for controlling distribution and use of digital works provides for attaching persistent usage rights to a digital work. Digital works are transferred between repositories which are used to request and grant access to digital works. Such repositories are also coupled to credit servers which provide for payment of any fees incurred as a result of accessing a digital work.

Claims

1-22. -22. (canceled)

23. A method for controlling the distribution and use of documents, the method comprising:

determining a usage right that specifies how a first document may be used or distributed, wherein the usage right includes information regarding embedding a watermark into a second document, the second document being generated as a result of exercising the usage right over the first document;

gathering watermark data while the usage right is exercised over the first document;

generating a watermark based on the gathered watermark data; and

embedding the generated watermark into the second document in accordance with the information included in the usage right.

24. The method of claim 23, wherein the usage right further includes information regarding gathering the watermark data.

25. The method of claim 23, wherein the usage right further includes information regarding generating the watermark based on the watermark data.

26. The method of claim 23, wherein the usage right further includes information regarding generating the second document.

27. The method of claim 23, wherein the step of gathering watermark data comprises gathering watermark data upon exercising the usage right over the first document.

28. The method of claim 23, wherein the usage right is a rendering right, and the second document is generated upon rendering of the first document.

29. A system for controlling the distribution and use of documents, the system comprising:

a usage right repository for determining a usage right that specifies how a first document may be used or distributed, wherein the usage right includes information regarding embedding a watermark into a second document, the second document being generated as a result of exercising the usage right over the first document;

a data repository for gathering watermark data while the usage right is exercised over the first document; and

a watermark repository for generating a watermark based on the gathered watermark data and embedding the generated watermark into the second document in accordance with the information in the usage right.

30. The system of claim 29, wherein the usage right further includes information regarding gathering the watermark data.

31. The system of claim 29, wherein the usage right further includes information regarding generating the watermark based on the watermark data.

32. The system of claim 29, wherein the usage right further includes information regarding generating the second document.

33. The system of claim 29, wherein the watermark data is gathered upon exercising the usage right over the first document.

34. The system of claim 29, wherein the usage right is a rendering right, and the second document is generated upon rendering of the first document.

35. A computer-readable medium comprising instructions for a computer system for controlling the distribution and use of documents, the instructions comprising the steps of:

determining a usage right that specifies how a first document may be used or distributed, wherein the usage right includes information regarding embedding a watermark into a second document, the second document being generated as a result of exercising the usage right over the first document;

gathering watermark data while the usage right is exercised over the first document;

generating a watermark based on the gathered watermark data; and

embedding the generated watermark into the second document in accordance with the information included in the usage right.

36. The computer-readable medium of claim 35, wherein the usage right further includes information regarding gathering the watermark data.

37. The computer-readable medium of claim 35, wherein the usage right further includes information regarding generating the watermark based on the watermark data.

38. The computer-readable medium of claim 35, wherein the usage right further includes information regarding generating the second document.

39. The computer-readable medium of claim 35, wherein the step of gathering watermark data comprises gathering watermark data upon exercising the usage right over the first document.

40. The computer-readable medium of claim 35, wherein the usage right is a rendering right, and the second document is generated upon rendering of the first document.
