Abstract

A multiple party system for distributing content. In one embodiment, four parties are involved in the system: a consumer, a service provider, an authenticator, and a content provider. The distribution of content from the content provider to the consumer is carried out using a predefined protocol, mutating IDs, and licenses. The authenticator controls the distribution of mutating IDs and verifies the identity of one or more participating parties.

Claims

1. A method of distributing content requested by a first party, the method comprising:

generating a first mutating identifier associated with the content;

repeatedly mutating a previously generated mutating identifier at at least one subsequent party, starting with the first mutating identifier;

terminating mutating a previously generated mutating identifier when the previously generated mutating identifier is authenticated;

encrypting the content based on the previously authenticated mutating identifier;

distributing the encrypted content to the first party; and

distributing a decryption key to the first party.

2. The method of claim 1, wherein the encrypted content is distributed to the first party by a second party, and the decryption key is distributed to the first party by a third party.

3. The method of claim 1, further comprising providing each of the parties with a license.

4. The method of claim 3, further comprising tagging the previously generated mutating identifier with a party license.

5. The method of claim 1, wherein mutating a previously generated mutating identifier further comprises:

tagging the previously mutating identifier with a party license; and

encrypting the previously tagged mutating identifier.

6. The method of claim 1, wherein the act of terminating mutating the previously generated mutating identifier when the previously generated mutating identifier is authenticated further comprises:

decrypting the previously generated mutating identifier; and

validating the decrypted mutating identifier.

7. The method of claim 1, further comprising tracking a use of the content by a second party.

8. The method of claim 1, further comprising discarding the previously generated mutating identifier.

9. The method of claim 8, further comprising modifying the first mutating identifier associated with the content after the content has been requested.

10. The method of claim 1, further comprising generating a new first mutating identifier associated with the content after the content has been requested.

11. A content distribution system comprising:

an authenticator;

a content provider, the content provider having content and a content identifier, and generating a first mutating identifier associated with the content identifier;

a consumer device, the consumer device operable to generate a request for the content; and

a service provider, the service provider operable to receive the request from the consumer device, receive the first mutating identifier from the content provider, generate a second mutating identifier associated with the first mutating identifier, distribute the second mutating identifier to the consumer device, the consumer device generating a third mutating identifier associated with the second mutating identifier, and distributing the third mutating identifier to the authenticator, the authenticator obtaining a validation of the request, the authenticator thereafter informing the service provider of the validation of the request, the content provider thereafter encrypting the content and sending the encrypted content to the consumer while the authenticator sends a decryption code to the consumer.

12. The system of claim 11, wherein the authenticator randomly generates a content provider license, a service provider license, and a consumer device license.

13. The system of claim 12, wherein the first mutating identifier is modified after the content has been requested.

14. The system of claim 12, wherein the second mutating identifier is associated with the service provider license.

15. The system of claim 12, wherein the third mutating identifier is associated with the consumer device license.

16. The system of claim 11, wherein obtaining a validity of the request comprises decrypting the third mutating identifier.

17. The system of claim 11, wherein the authenticator tracks the use of the content.

18. The system of claim 11, wherein the plurality of the mutating identifiers are discarded.

19. The system of claim 11, wherein a new first mutating identifier is associated with the content after the content has been requested.

20. A method of content distribution, the method comprising:

making a request by a consumer for content;

generating a first mutating identifier associated with the content at a content provider;

distributing the first mutating identifier from the content provider to a service provider;

generating a second mutating identifier with the first mutating identifier at the service provider;

distributing the second mutating identifier from a service provider to the consumer;

generating a third mutating identifier with the second mutating identifier at the consumer;

distributing the third mutating identifier from a service provider to an authenticator;

determining the request from the third mutating identifier;

generating encrypted content based on the request at the content provider;

distributing the encrypted content to the consumer; and

distributing a key from the authenticator to the consumer.

21. The method of claim 20, further comprising providing each identifier with a license.

22. The method of claim 21, further comprising tagging the identifier with the license.

23. The method of claim 20, wherein mutating an identifier further comprises:

tagging the identifier with a license; and

encrypting the tagged identifier.

24. The method of claim 20, wherein determining the request from the third mutating identifier further comprises:

decrypting the third mutating identifier; and

validating the decrypted mutating identifier.

25. The method of claim 20, further comprising tracking a use of the content.

26. The method of claim 20, further comprising discarding the plurality of the mutating identifiers.

27. The method of claim 26, further comprising generating a new first mutating identifier associated with the content after the content has been requested.

28. A method of content distribution, the method comprising:

encrypting a plurality of identifiers, each identifier identifying a party;

encapsulating the encrypted identifier at each party; and

authenticating one of the parties with the encapsulated identifier.

29. The method of claim 28, further comprising distributing content based on the authenticated identifier.

30. The method of claim 29, further comprising discarding the identifier after the distribution.

31. The method of claim 28, wherein encapsulating the encrypted identifier further comprises tagging an identifier to the encrypted identifier.

32. The method of claim 28, further comprising providing at least three parties.

33. The method of claim 28, wherein authenticating one of the parties further comprises decrypting the encapsulated identifier.

34. The method of 28, further comprising generating a new identifier for each party.

35. The method of 28, further comprising requesting content from a party.
