Abstract

A method and system for managing use of items having usage rights associated therewith including a point of capture system adapted to generate content of a future event when the event occurs, a content distributor adapted to generate a rights label having usage rights associated with content of the future event before the content is created, the rights label having a distribution key for encrypting the content as the content is generated, the distribution key being encrypted with a public key. The system also includes a license server adapted to generate a license associate with the content from the rights label before the content is generated, the license including the distribution key encrypted with the public key, and a content distributor adapted to distribute the license before the content is generated.

Claims

1. A rights management system for managing use of content having usage rights associated therewith, said system comprising:

a point of capture system adapted to generate content of a future event when the event occurs;

a content distributor adapted to generate a rights label having usage rights associated with content of the future event before the content is generated by said point of capture system, said rights label having a securing mechanism that secures said content when said content is generated; and

a license server adapted to store said rights label and to issue a license associated with the content from said rights label before the content is generated, said license including a mechanism for unlocking said securing mechanism;

wherein said content distributor is further adapted to distribute said license before the content is generated.

2. The rights management system of claim 1, wherein said rights label includes a distribution key for encrypting said content.

3. The rights management system of claim 2, wherein said distribution key is encrypted with a public key.

4. The rights management system of claim 3, wherein said public key used to encrypt said distribution key is associated with said content distributor.

5. The rights management system of claim 4, wherein said license issued is a distribution license which is provided to said content distributor before said point of capture system generates the content.

6. The rights management system of claim 5, wherein said distribution license includes distributor rights that allow distribution of the generated content.

7. The rights management system of claim 3, wherein said public key used to encrypt said distribution key is associated with said point of capture system.

8. The rights management system of claim 7, wherein said license issued is a distribution license which is provided to said point of capture system before said point of capture system generates the content.

9. The rights management system of claim 3, wherein said public key used to encrypt said distribution key is associated with an end user.

10. The rights management system of claim 9, wherein said license issued is a consumer license which is provided to said end user before said point of capture system generates the content.

11. The rights management system of claim 10, wherein said consumer license includes consumer rights that allow use of the generated content.

12. The rights management system of claim 11, further including a rendering device accessible by said end user, said rendering device being adapted to decrypt said distribution key provided in said consumer license using a private key associated with said end user.

13. The rights management system of claim 12, wherein said rendering device is further adapted to decrypt the encrypted content using said decrypted distribution key.

14. The rights management system of claim 13, wherein said rendering device includes a display device for displaying the decrypted content.

15. The rights management system of claim 1, further including a vendor adapted to offer rights to the future content for sale to said end user before said point of capture system generates the content.

16. The rights management system of claim 15, wherein said vendor is a web site accessible through Internet.

17. The rights management system of claim 15, wherein said content is at least one of an audio file, a video file, and a digital multimedia file.

18. A method for managing use of content having usage rights associated therewith, said method comprising the steps of:

generating a rights label having usage rights associated with content of a future event before the content is generated by a point of capture system, said rights label having a securing mechanism for securing the content;

issuing a license associated with the content based on said rights label before the content is generated by said point of capture system, said license including a mechanism for unlocking said securing mechanism; and

distributing said license before the content is generated.

19. The method of claim 18, wherein said rights label includes a distribution key for encrypting said content.

20. The method of claim 19, further including the step of encrypting said content with said distribution key when said content is generated by said point of capture system.

21. The method of claim 20, further including the step of encrypting said distribution key with a public key.

22. The method of claim 21, wherein said public key used to encrypt said distribution key is associated with said content distributor.

23. The method of claim 22, wherein said license issued is a distribution license which is provided to said content distributor before said point of capture system generates the content.

24. The method of claim 23, wherein said distribution license includes distributor rights that allow distribution of the generated content.

25. The method of claim 21, wherein said public key used to encrypt said distribution key is associated with said point of capture system that generates the content when the future event occurs.

26. The method of claim 25, wherein said license issued is a distribution license which is provided to said point of capture system before said point of capture system generates the content.

27. The method of claim 21, wherein said public key used to encrypt said distribution key is associated with an end user.

28. The method of claim 27, wherein said license issued is a consumer license which is provided to said end user before said point of capture system generates the content.

29. The method of claim 28, further including the step of decrypting said distribution key provided in said consumer license using a private key associated with said end user.

30. The method of claim 29, further including the step of decrypting the encrypted content using said decrypted distribution key.

31. The method of claim 30, further including the step of displaying the decrypted content on a rendering device.

32. The method of claim 18, further including the step of offering rights to said future content for sale to said end user before said point of capture system generates the content.

33. The method of claim 32, wherein said content is at least one of an audio file, a video file, and a digital multimedia file.
