Transfer of digital rights management information

1. A method performed on a device, where the method comprises:

storing content and corresponding digital rights management security information received, via a network, from a source device that previously played at least a portion of the content;

automatically attempting to receive authorization not to deactivate the digital rights management security information at regular intervals;

allowing rendering of the content according to the digital rights management security information when the authorization is received; and

deactivating the digital rights management security information when the authorization is not received.

2. The method of claim 1 , where the digital rights management security information was deactivated prior to storing the digital rights management security information, and

where automatically attempting to receive the authorization at regular intervals comprises attempting to receive the authorization at least once every period of time,

the method further comprising:

receiving the authorization based on at least one of whether the source device is lost or stolen or whether another device has requested reactivation of the digital rights management security information.

3. The method of claim 1 , where deactivating the digital rights management security information when the authorization is not received comprises deactivating the digital rights management security information when the authorization is not received after a period of time,

where the authorization is not received at least one of when the source device is lost or stolen or when another device has requested reactivation of the digital rights management security information.

4. The method of claim 3 , where deactivating the digital rights management security information when the authorization is not received comprises deactivating the device.

5. A method performed in a device, the method comprising:

receiving, via a network, digital rights management security information and content from a source device that previously played at least a portion of the content, the digital rights management security information having been deactivated in the source device;

reactivating the digital rights management security information; and

rendering, by the device, the content according to the digital rights management security information.

6. The method of claim 5 , where the digital rights management security information corresponds to the content,

the method further comprising receiving authorization to reactivate the digital rights management security information,

where the digital rights management security information includes at least one of time information associated with rendering the content or information identifying a type of device that is allowed to render the content, and

where the content is rendered when the authorization to reactivate the digital rights management security information is received and based on the at least one of the time information associated with rendering the content or the information identifying the type of device that is allowed to render the content.

7. The method of claim 6 , further comprising transmitting confirmation of reactivating the digital rights management security information.

8. The method of claim 5 , further comprising decrypting the digital rights management security information,

where reactivating the digital rights management security information includes:

reactivating the decrypted digital rights management security information.

9. A device comprising:

a communication interface to:

receive, via a network, digital rights management security information and content from a source device that previously played at least a portion of the content, the digital rights management information having been deactivated in the source device; and

processing logic to:

reactivate the digital rights management security information, and

render the content according to the digital rights management security information.

10. The device of claim 9 , where the communication interface further receives authorization to reactivate the digital rights management security information,

where the digital rights management security information includes at least one of time information associated with rendering the content or a count of rendering the content, and

where the content is rendered when the digital rights management security information has been reactivated and based on the at least one of the time information associated with rendering the content or the count of rendering the content.

11. The device of claim 10 , where the communication interface further transmits confirmation of reactivating of the digital rights management security information.

12. The device of claim 9 , where the processing logic is further to decrypt the digital rights management security information,

where the processing logic is to reactivate the digital rights management security information after the digital rights management security information has been decrypted.

13. The device of claim 9 , where the device includes a first mobile terminal, and

where the source device includes a second mobile terminal.

14. A non-transitory computer-readable memory device for storing a plurality of instructions which, when executed by at least one processor, cause the at least one processor to:

render first content according to first digital rights management security information that corresponds to the first content;

transmit the first digital rights management security information and the first content;

deactivate the first digital rights management security information when the first digital rights management security information has been transmitted;

receive, via a network, second digital rights management security information and second content from a source that previously played at least a portion of the second content,

where the second digital rights management security information is deactivated when the second digital rights management security information has been transmitted by the source;

reactivate the second digital rights management security information; and

render the second content according to the second digital rights management security information.

15. The computer-readable memory device of claim 14 , further comprising an instruction which, when executed, causes the at least one processor to receive authorization to deactivate the first digital rights management security information.

16. The computer-readable memory device of claim 14 , further comprising an instruction which, when executed, causes the at least one processor to transmit confirmation of deactivation of the first digital rights management security information.

17. The computer-readable memory device of claim 14 , further comprising an instruction which, when executed, causes the at least one processor to receive authorization to reactivate the second digital rights management security information,

where the second digital rights management security information includes at least one of time information associated with rendering the second content or information identifying a type of device that is allowed to render the second content, and

where the second content is rendered based on the at least one of the time information associated with rendering the second content or the information identifying the type of device that is allowed to render the second content.

18. The computer-readable memory device of claim 17 , further comprising an instruction which, when executed, causes the at least one processor to transmit confirmation of reactivation of the second digital rights management security information.

19. The computer-readable memory device of claim 14 , further comprising an instruction which, when executed, causes the at least one processor to repeatedly transmit the first digital rights management security information and the corresponding content.

20. The computer-readable memory device of claim 14 , further comprising an instruction which, when executed, causes the at least one processor to encrypt the first digital rights management security information before transmitting the first digital rights management security information.

21. A method comprising:

authorizing a source device to deactivate digital rights management security information corresponding to content, the source device having stored the digital rights management security information and the content, and the source device having played at least a portion of the content; and

authorizing a target device to reactivate the digital rights management security information corresponding to the content, the digital rights management security information and the content having been transmitted from the source device, via a network, to the target device.
