Abstract

The present invention includes a method and system for exchanging digital media. According to the present invention, a method and system includes transmitting access rights between system users wherein the access rights allow access to certain types of transferable media. The access rights can be transmitted by paying a fee to the transmitting user. A first aspect of the present invention includes a method of exchanging digital media. The method includes receiving a user identifier, securely accessing device based on a first transaction between the user identifier and the device and allowing the device to transmit at least one access right to a media to the user identifier based on a second transaction between the user identifier and the device.

Claims

1. A method of exchanging digital media comprising:

receiving a user identifier;

securely accessing a device based on a first transaction between the user identifier and the device; and

allowing the device to transmit at least one access right to a media to the user identifier based on a second transaction between the user identifier and the device.

2. The method of claim 1 wherein the user identifier comprises a media card.

3. The method of claim 1 wherein the device comprises a hot spot.

4. The method of claim 1 wherein the device comprises a media playing device.

5. The method of claim 1 wherein the at least one access right comprises a license to use the media.

6. The method of claim 1 wherein the first transaction comprises an authentication of the user identifier.

7. The method of claim 6 wherein the user identifier includes a medium of exchange and the second transaction comprises transmitting the medium of exchange to the memory component of the device.

8. The method of claim 1 further comprising:

utilizing the user identifier to access the media via another device after completing the second transaction.

9. The method of claim 8 wherein the another device comprises a media playing device.

10. The method of claim 1 wherein the first and second transaction are conducted offline.

11. The method of claim 1 wherein allowing the device to transmit at least one access right to a media comprises allowing the device to transmit a decryption key to the media.

12. A system for exchanging digital media comprising:

a user identifier wherein the user identifier includes a memory portion;

a first device wherein the first device includes;

a first mechanism for accessing the memory portion of the user identifier; and

a memory component wherein the memory component includes at least one access right to a media; and

a second device wherein the second device includes a second mechanism for accessing the memory portion of the user identifier wherein the second device is capable of accessing the media.

13. The system of claim 12 wherein the user identifier comprises a media card.

14. The system of claim 12 wherein the first and second device comprise media playing devices.

15. The system of claim 14 wherein the first and second mechanisms each comprise a media card reader.

16. The system of claim 12 wherein the at least one access right comprises a license to use the media.

17. The system of claim 16 wherein license to use the media comprises a decryption key to the media.

18. The system of claim 12 wherein the second device comprises a hot spot.

19. A device for exchanging digital media comprising:

a memory component for storing at least one encrypted media file;

a media card reader coupled to the memory component; and

a central processing unit coupled to the memory component and the media card reader wherein the central processing unit includes logic for processing an access right to a media file based on a transaction between the media card reader and the central processing unit.

20. The device of claim 19 wherein the access right comprises a decryption key to the at least one encrypted media file.

21. The device of claim 20 wherein the transaction comprises:

determining if a media card is in the media card reader; and

accessing the decryption key from the media card if a media card is in the media card reader.

22. A method of purchasing digital media comprising:

allowing a first device to securely access a second device;

transmitting an access right to a media from the second device to the first device; and

transmitting a medium of exchange from the first device to the second device in response to the transmission of the access right to the media.

23. The method of claim 22 wherein the first and second devices are peer devices capable communicating in a peer-to-peer fashion.

24. The method of claim 22 wherein transmitting an access right to a media from the second device to the first device further comprises transmitting a decryption key to the media from the second device to the first device.

25. The method claim 22 wherein the second device comprises a hot spot.

26. The method of claim 22 wherein the first and second devices are media playing devices.

27. The method of claim 22 wherein the acts of transmitting an access right to a media and transmitting the medium of exchange are conducted offline.

28. A computer program product for exchanging media, the computer program product comprising a computer usable medium having computer readable program means for causing a computer to perform the steps of:

allowing a device to access a user identifier based on a first transaction between the user identifier and the device; and

allowing the device to transmit at least one access right to the media to the user identifier based on a second transaction between the user identifier and the device.

29. The computer program product of claim 28 wherein the user identifier comprises a media card.

30. The computer program product of claim 28 wherein the device comprises a hot spot.

31. The computer program product of claim 28 wherein the device comprises a media playing device.

32. The computer program product of claim 28 wherein the at least one access right comprises a license to use right.

33. The computer program product of claim 28 wherein the first transaction comprises an authentication of the user identifier.

34. The computer program product of claim 33 wherein the user identifier includes a medium of exchange and the second transaction comprises transmitting the medium of exchange to the device.
