Abstract

The invention illustrates a system and method of sharing content with multiple peer device while protecting the content from unauthorized use. In one embodiment, the system and method comprises: identifying a plurality of peer devices within a predetermined area wherein each of the plurality of peer devices includes an interface framework; directly transmitting content among the plurality of devices; and a selected plurality of peer devices requesting a license from a digital rights management server for the content, wherein the selected plurality of peer devices possess the content, wherein the interface framework is configured to allow the plurality of peer devices to directly communicate and utilize an application

Other aspects and advantages of the invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrated by way of example of the principles of the invention.

Claims

1. A method of sharing protected content between peer devices, comprising:

detecting that a first and second peer device are sufficiently proximal to share content protected under digital rights management;

determining if it is desirable for the first and second peer devices to interact;

communicating a content query between the first and second peer device;

copying or moving protected content between the first peer device as a lender and the second peer device as a borrower in response to said content query via a first interface framework;

reporting the copying or moving of protected content between the first and second peer devices to a digital rights management server by the first peer device, second peer device, or a combination of the first and second peer device, within a license received for said protected content; and

automatically returning, or deactivating, said license for said protected content to the lender in response to meeting time or use conditions, or if a payment is not made to the digital rights management server.

2. The method according to claim 1, wherein said content subject to said copying comprises:

a provisional license in which content use by the borrower is limited as to time, number of accesses, or a combination of time and accesses;

or

a preview license in which sample portions of the content are made available for access by the borrower.

3. The method according to claim 1, wherein said protected content subject to said copying or moving comprises content whose associated license is removed from the lender and transferred to the borrower.

4. The method according to claim 1, wherein the first or second peer device is selected from the group of consumer electronics devices consisting of a networked portable player, cellular telephone, personal digital assistant, media player, pager, and personal computer.

5. The method according to claim 1, further comprising transmitting a payment from the second peer device to a digital rights management server through a second interface framework, in response to said copying or moving of said protected content for which the borrower purchases their own license.

6. The method according to claim 5, further comprising:

transmitting a license to the second peer device from a digital rights management server through a second interface framework;

wherein said protected content copied or moved from the first peer device can be utilized by the second peer device.

7. The method according to claim 1:

wherein the first interface framework includes a plug-in for translating a command from an application; and

wherein the plug-in comprises an adaptor and a native protocol.

8. The method according to claim 1, wherein said determining desirability of peer interaction comprises determining that the peer devices are on each others contact list.

9. The method according to claim 1, wherein the application is selected from the group of applications consisting of:

an instant messaging application, a content distribution network application, a proximity application, and a digital rights management application.

10. The method according to claim 1, wherein said content query comprises a metadata sharing process.

11. The method according to claim 1, wherein said content which was moved to said borrower is also automatically returned to the lender in response to time or use conditions being met, or if a payment is not made to the digital rights management server.

12. The method according to claim 1, wherein said lender is responsible for completing a payment to a digital rights management server to prevent the license for said content which was moved or copied from being deactivated.

13. The method according to claim 1, wherein said content query comprises a metadata sharing process in which metadata is selected from the group of metadata consisting of content listings, tracks, device identification, licensing information, user profile, sex, age name, location, and interests which are shared between the first and second peer devices.

14. A system for extending protected content access between peers during peer-to-peer communications, comprising:

a digital rights management application configured to receive and transmit a set of commands;

a first peer device having an interface framework for translating a set of commands between the digital rights management application and the first peer device;

wherein the first peer device is configured to directly communicate with a second peer device;

a plug-in configured for communicating with the interface framework and an application program;

wherein the plug-in is configured to translate requests from the application program into a peer device request that is understood by a peer device;

wherein said system is configured for copying or moving protected content directly from said first peer device as lender to said second peer device as borrower if said second peer device is within a proximity of said first peer device that allows for direct transmitting; and

programming executable within said digital rights management application for,

receiving reports in response to the lending or transfer of protected content between said first and second peer devices, and

deactivating or returning, automatically, the license for protected content which has been copied or moved from the first peer device to the second peer device if a payment is not made through said digital rights management application in response to said reports,

wherein said protected content whose license is deactivated or returned does not comprise provisional or sample content which is subject to playback limitations.

15. The system according to claim 14, wherein said provisional or sample content comprises:

a provisional license in which content use by the borrower is limited as to time, number of accesses, or a combination of time and accesses;

or

a preview license in which sample portions of the content are made available for access by the borrower.

16. The system according to claim 14 wherein the interface framework includes an adaptor for translating the set of commands for the first peer device.

17. The system according to claim 14 wherein said content query comprises a metadata sharing process.

18. The system according to claim 17 wherein said content query comprises a metadata sharing process in which metadata selected from the group of metadata consisting of content listings, tracks, device identification, licensing information, user profile, sex, age name, location, and interests which are shared between the first and second peer devices.

19. The system according to claim 14 wherein the second peer device is configured to receive a license from the application for utilizing the content.

20. The system according to claim 14 wherein the first or second peer device is selected from the group of consumer electronics devices consisting of a networked portable player, a cellular telephone, personal digital assistant, media player, pager, and personal computer.

21. The system according to claim 14, wherein said returning of the license comprises automatically returning the license from the borrower to the lender in response to time or use conditions being met, or if a payment is not made to the digital rights management application for said copying or moving of said protected content.
