System for controlling the distribution and use of digital works
A method, system and software for securely rendering digital documents, including storing a digital document in a document platform; and storing a usage right associated with the digital document. The usage right specifies a manner of use indicating the manner in which the digital document can be rendered by the document platform. The digital document comprises plural parts of digital content. The usage right includes plural usage rights respectively associated with each of the plural parts of digital content. Whether one of the parts of the digital document may be rendered by the document platform is determined based a respective usage right. If the respective usage right allows the digital document to be rendered on the document platform, the corresponding part of the digital document is rendered by the document platform.
1. A method for securely rendering digital documents, comprising:
retrieving, by a document platform, a digital document and at least one usage right associated with the digital document from a document repository, the at least one usage right specifying a manner of use indicating the manner in which the digital document can be rendered;
storing the digital document and the at least one usage right in separate files in the document platform;
determining, by the document platform, whether the digital document may be rendered based on the at least one usage right; and
if the at least one usage right allows the digital document to be rendered on the document platform, rendering the digital document by the document platform.
2. The method as recited in claim 1 , wherein the manner of use includes the number of times the digital document can be rendered.
3. The method as recited in claim 1 , wherein at least a portion of the digital document is a software program.
4. The method as recited in claim 1 , wherein the at least one usage right comprises a revenue identifier for identifying a revenue owner of the digital document.
5. The method as recited in claim 1 , wherein the at least one usage right also specifies one or more conditions which must be satisfied before the manner of rendering may be exercised.
6. The method as recited in claim 5 , wherein at least one condition includes determining the presence of a digital ticket.
7. The method as recited in claim 1 , wherein the at least one usage right or a part of the digital document is stored on a removable storage device.
8. The method as recited in claim 1 , wherein at least one part of the digital document and the at least one usage right are stored on a same device.
9. The method as recited in claim 1 , wherein at least one part of the digital document and the at least one usage right are stored on different devices.
10. A method for securely rendering digital documents, comprising:
storing a digital document and at least one usage right in separate files in a document repository, wherein the at least one usage right is associated with the digital document;
receiving a request from a document platform for access to the digital document;
determining, by the document platform, whether the request may be granted based on the at least one usage right, the determining step including authenticating the document platform and determining whether the at least one usage right includes a manner of use that allows transfer of the digital document to the document platform;
if the at least one usage right allows the transfer of the digital document to the document platform, transferring the digital document and the at least one usage right associated with the digital document to the document platform;
storing the digital document and the at least one usage right in the document platform, wherein the at least one usage right is stored in a separate file from the digital document; and
rendering the digital document by the document platform.
11. The method as recited in claim 10 , wherein at least a portion of the digital document is a software program.
12. The method as recited in claim 10 , wherein the at least one usage right comprises a revenue identifier for identifying a revenue owner of the digital document.
13. The method as recited in claim 10 , wherein the at least one usage right also specifies one or more conditions which must be satisfied before the manner of rendering may be exercised.
14. The method as recited in claim 13 , wherein at least one condition includes determining the presence of a digital ticket.
15. The method as recited in claim 10 , wherein the at least one usage right or a part of the digital document is stored on a removable storage device.
16. The method as recited in claim 10 , wherein at least one part of the digital document and the at least one usage right are stored on a same device.
17. The method as recited in claim 10 , wherein at least one part of the digital document and the at least one usage right are stored on different devices.
18. A method for securely rendering digital documents, comprising:
receiving a request from a document platform to transfer a digital document from a document repository to the document platform, the digital document having at least one usage right associated therewith;
authenticating the document platform by accessing at least one identifier associated with the document platform or with a user of the document platform and determining whether the identifier is associated with at least one of the document platform and a user authorized to use the digital document;
if the authenticating step is successful, determining whether the digital document may be transferred and stored on the document platform based on a manner of use included in the at least one usage right;
if the at least one usage right allows the digital document to be transferred to the document platform, transferring the digital document and the at least one usage right associated with the digital document to the document platform;
storing the digital document and the at least one usage right in the document platform, wherein the at least one usage right is stored in a separate file from the digital document; determining, by the document platform, whether the digital document may be rendered based on the at least one usage right; and
if the at least one usage right allows the digital document to be rendered on the document platform, rendering the digital document by the document platform.
19. The method as recited in claim 18 , wherein at least a portion of the digital document is a software program.
20. The method as recited in claim 18 , wherein the at least one usage right comprises a revenue identifier for identifying a revenue owner of the digital content.
21. The method as recited in claim 18 , wherein the at least one usage right also specifies one or more conditions which must be satisfied before the manner of rendering may be exercised.
22. The method as recited in claim 21 , wherein at least one condition includes determining the presence of a digital ticket.
23. The method as recited in claim 18 , wherein the at least one usage right or a part of the digital document is stored on a removable storage device.
24. The method as recited in claim 18 , wherein at least one part of the digital document and at least one usage right are stored on a same device.
25. The method as recited in claim 18 , wherein at least one part of the digital document and the at least one usage right are stored on different devices.
