Abstract

An enforceable property right and a system for controlling the manner of use of an item in accordance with usage rights. The enforceable property right includes an item ticket having a security mechanism incorporated therein and specifying an item for which the item ticket can be redeemed and a license associated with the item ticket. The license includes usage rights specifying a manner of use for redeeming the item ticket and a mechanism for unlocking said security mechanism.

Claims

1. A system for enforcing a property right in an item in accordance with usage rights, said system comprising:

a processor; and

a memory operatively coupled to the processor and containing instructions that, when executed by the processor, cause the processor to carry out the steps of;

preparing an item ticket specifying said item, said item ticket having a security mechanism incorporated therein, wherein said security mechanism can be unlocked to allow access to said item; and

associating a license with said item ticket, said license specifying a first set of usage rights associated with the unlocking of said item ticket and a second set of usage rights associated with the use of said item, and including a mechanism for unlocking said security mechanism;

wherein said license comprises data that is interpretable by a computing device to thereby specify the computing device to unlock said security mechanism incorporated in said item ticket using said mechanism in accordance with said first set of usage rights; and

wherein said second set of usage rights includes data that is interpretable by the computing device and specifies how the computing device controls use of said item.

2. The system as recited in claim 1, wherein said license further includes conditions that must be satisfied to activate said mechanism for unlocking.

3. The system as recited in claim 1, wherein said item ticket includes a description of the item.

4. The system as recited in claim 1, wherein said item ticket includes an ID correlated to the item.

5. The system as recited in claim 1, wherein said item ticket includes limitations specified by said license.

6. The system as recited in claim 5, wherein said limitations are expressed as conditions.

7. The system as recited in claim 1, wherein said security mechanism is encryption.

8. The system as recited in claim 1, wherein said item includes goods.

9. The system as recited in claim 1, wherein said item includes services.

10. The system as recited in claim 1, wherein said license includes a specification of a corresponding item ticket.

11. The system as recited in claim 1, wherein said item is information.

12. The system as recited in claim 11, wherein said license further comprises usage rights specifying access to the information and conditions of the access.

13. The system as recited in claim 12, wherein said conditions include a security or trust rating.

14. The system as recited in claim 1, wherein said item is an online service.

15. The system as recited in claim 14, wherein said license further comprises usage rights specifying access to the online service and conditions of the access.

16. The system as recited in claim 15, wherein said conditions include a security or trust rating.

17. The system as recited in claim 2, wherein said license also includes post-license conditions that do not need to be satisfied to activate said security mechanism and wherein a specification of said item and said post-license conditions can be rendered by the computing device only when the security device is unlocked.

18. The system as recited in claim 2, wherein said license includes state variables.

19. The system as recited in claim 1, wherein said unlocking mechanism is operative to permit the item ticket to be rendered as a human readable description.

20. The system as recited in claim 1, wherein said unlocking mechanism is operative to permit the item ticket to be rendered as a computer readable code.

21. The system as recited in claim 1, wherein said usage rights include meta-rights which permit rights in the item to be granted to downstream parties.

22. The system as recited in claim 1, wherein the item is a financial instrument.

23. The system as recited in claim 1, wherein the item is a legal document.

24. The system as recited in claim 1, wherein the item is real estate.

25. The system as recited in claim 1, wherein said item ticket further includes a post license condition.

26. The system as recited in claim 25, wherein said post license condition includes data that is interpretable by the computing device and specifies how the computing device controls use of said item.
