Abstract

A system for maintaining a secure content library includes a server, which manages requests for copyrighted content and encrypts the content using a key server, which generates unique keys and associates the keys with the copyrighted content to create a token. A gateway receives the token and interacts with the server over a network. A client storage box interacts with the gateway to decode the token in accordance with a security protocol and sends a content key back to the server to enable the content to be downloaded and decoded, the storage box including memory for storing downloaded content. The client storage box has a use key that is updated by the server after a predetermined number of accesses to the content to enable further accessing of the content.

Claims

1. A system for maintaining a secure content library, comprising:

a server which manages requests for copyrighted content and encrypts the content using a key server which generates unique keys and associates the keys with the copyrighted content to create a token wherein the server includes a revolving license key server such that a revolving license key is issued and updated to the user as a use key after a predetermined number of accesses to the content;

a gateway which receives the token and interacts with the server over a network; and

a client storage box which interacts with the gateway to decode the token in accordance with a security protocol and sends the token back to the server to enable the content to be downloaded and decoded, the storage box including memory for storing downloaded content;

the client storage box having the use key that is updated by the server after a predetermined number of accesses to the content to enable further accessing of the content.

2. The system as recite in claim 1, wherein the client storage box is detachable and portable without deleting the content.

3. The system as recited in claim 1, further comprising a system audit module which intermittently compares content stored in the storage box against a master content list stored on the server, wherein the server controls operation of the storage box in the event that a discrepancy occurs between the master content list and the content stored on the storage box.

4. The system as recited in claim 1, wherein the storage box includes privilege information, which limits content available for purchasing and accessing.

5. The system as recited in claim 1, wherein the content includes movies and the storage box stores the movie content.

6. The system as recited in claim 1, wherein the content includes a complete listing of movies purchased and owned by a customer wherein the content is stored on the storage box, in a master list at the server or both.

7. The system as recited in claim 1, wherein the storage box stores only digital words permitting rights to view the content.

8. The system as recited in claim 1, wherein the storage box is employed to transfer a library of content for rendering at any remote location.

9. The system as recited in claim 1, wherein the server further comprises a database, which stores one or more of unique keys, account information and content.

10. The system as recited in claim 1, wherein the unique keys are encrypted with the client requested content and are employed to update the use keys.

11. The system as recited in claim 1, wherein the storage box includes a free pass to substitute for a use key when the storage box lacks access to the server.

12. The system as recited in claim 1, wherein one of the tokens, and the use keys are encrypted based on data in one or more of the client'"'"'s hardware information, the client'"'"'s account information and a portion of the content.

14. The system as recited in claim 1, wherein the revolving license server includes a revolving security protocol (RSP) to generate a revolving key unique to each individual piece of content.

15. The system as recited in claim 1, further comprising a certification for proof of purchase and for library cataloging content, the certification including unique identifiers, a cert number, at least a portion of content and hardware identifiers.

13. (canceled)

16. A system for maintaining a secure content library, comprising:

a server which manages requests for copyrighted content and encrypts the content using a key server which generates unique keys and associates the keys with the copyrighted content to create tokens;

a plurality of gateways remotely disposed relative to each other and the server which receive the token and interact with the server over a network;

a client storage box which interacts with the gateways to decode the token in accordance with a security protocol and sends a content key back to the server through any of the gateways to enable the content to be downloaded at the location of the storage box, the storage box including memory for storing downloaded content and a free pass to substitute for a use key when the storage box lacks access to the server;

a system audit module which intermittently compares content stored in the storage box against a master content list stored on the server, wherein the server controls operation of the storage box in the event that a discrepancy occurs between the master content list and the content stored on the storage box.

17. The system as recite in claim 16, wherein the client storage box is detachable and portable without deleting the content.

18. The system as recited in claim 16, wherein the storage box includes read only memory for storing the content.

19. The system as recited in claim 16, wherein the storage box includes privilege information, which limits content available for purchasing and accessing.

20. The system as recited in claim 16, wherein the content includes movies and the storage box stores the movie content.

21. The system as recited in claim 16, wherein the storage box stores only digital words permitting rights to view the content from the server.

22. The system as recited in claim 16, wherein the storage box is employed to transfer a library of content for rendering at any remote location.

23. The system as recited in claim 16, wherein the server further comprises a database, which stores one or more of keys, account information and content.

25. The system as recited in claim 16, wherein the content includes a complete listing of movies purchased and owned by a customer wherein the content is stored on the storage box, in a master list at the server or both.

29. A system for maintaining a secure content library, comprising:

a server which manages requests for copyrighted content and encrypts the content using a key server which generates unique keys and associates the keys with the copyrighted content to create a token a gateway which receives the token and interacts with the server over a network; and

a client storage box which interacts with the gateway to decode the token in accordance with a security protocol and sends the token back to the server to enable the content to be downloaded and decoded, the storage box including memory for storing downloaded content;

the client storage box having a use key that is updated by the server after a predetermined number of accesses to the content to enable further accessing of the content, the storage box including a free pass to substitute for a use key when the storage box lacks access to the server.
