Abstract

A method of enabling roaming of a rights object in a digital rights management (DRM) system is provided. The method includes issuing disposable authentication information to a mobile device, receiving a request for a remote authentication as well as the authentication information from an unauthorized device, transmitting a query required for the remote authentication to the unauthorized device, receiving a response to the query from the unauthorized device, and transmitting data that approves of the authentication of the unauthorized device to the unauthorized device.

Claims

1. A method of enabling roaming of a rights object in a digital rights management (DRM) system, the method comprising:

issuing disposable authentication information to a mobile device;

receiving a request for a remote authentication as well as the authentication information from an unauthorized device;

transmitting a query required for the remote authentication to the unauthorized device;

receiving a response to the query from the unauthorized device; and

transmitting data that approves of the authentication of the unauthorized device to the unauthorized device.

2. The method of claim 1, further comprising storing an identifier of the mobile device.

3. The method of claim 2, further comprising checking if the identifier included in the request for the remote authentication matches the mobile device identifier after the receiving of the request for the remote authentication.

4. The method of claim 1, further comprising checking if the unauthorized device is included in a certification revocation list after the receiving of the request for the remote authentication.

5. The method of claim 1, wherein the mobile device stores the disposable authentication information.

6. The method of claim 1, wherein the data that approves of the authentication of the unauthorized device is encoded in a key included in the disposable authentication information.

7. A method of enabling roaming of a rights object in a digital rights management (DRM) system, the method comprising:

receiving disposable authentication information from a representative device;

requesting remote authentication for an unauthorized device using the disposable authentication information;

receiving the result of the remote authentication from the unauthorized device; and

transmitting a disposable rights object to the unauthorized device.

8. The method of claim 7, further comprising:

receiving a remote authentication query from the unauthorized device; and

transmitting a response to the remote authentication to the unauthorized device after the requesting of the remote authentication.

9. The method of claim 7, wherein the remote authentication query or the remote authentication result is encoded in a key included in the disposable authentication information.

10. The method of claim 7, further comprising transmitting a mobile device identifier to the representative device before the receiving of the disposable authentication information.

11. The method of claim 7, wherein the device is portable, and stores the disposable authentication information.

12. A method of enabling roaming of a rights object in a digital rights management (DRM) system, the method comprising:

receiving a remote authentication request message from a mobile device;

requesting the message for remote authentication of a representative device;

receiving a query required for the remote authentication from the representative device;

transmitting a response to the query to the representative device; and

receiving data that approves of the authentication from the representative device.

13. The method of claim 12, further comprising:

transmitting the query to the mobile device; and

receiving a response to the query from the mobile device after the receiving of the query.

14. The method of claim 12, further comprising:

transmitting data that approves of the authentication to the mobile device; and

receiving a disposable rights object from the mobile device after the approving of the authentication.

15. A device comprising:

a rights object storage unit that stores a rights object;

an authentication unit that issues disposable authentication information to a mobile device;

a receiver that receives a request for remote authentication as well as the disposable authentication information from an unauthorized device; and

a transmitter that transmits a query required for the remote authentication to the unauthorized device, wherein the receiver receives a response to the query from the unauthorized device and the transmitter transmits data that approves of the authentication of the unauthorized device to the unauthorized device.

16. The device of claim 15, wherein the authentication unit stores and deletes the disposable authentication information, and includes a key that encodes the query.
