Abstract

Methods and systems for handling a plurality of digital assets on a mobile device, wherein backups of the plurality of digital assets are created so as conform to digital rights management issues. Encrypted versions and/or links of the plurality of digital assets may be stored so that the mobile device or other electronic devices may access the backups.

Claims

1. A method for handling a plurality of digital assets on a mobile device, comprising the steps of:

creating backups of the plurality of digital assets by creating, on the mobile device, encrypted versions of the plurality of digital assets;

accessing the encrypted version of a digital asset in order to restore the digital asset for use on the mobile device.

2. The method of claim 1, further comprising the steps of:

creating backups of the plurality of digital assets by automatically storing, on the mobile device, references to locations where the plurality of digital assets are accessible;

wherein the locations are remote locations with respect to the mobile device;

accessing one of the stored references in order to restore a digital asset for use on the mobile device.

3. The method of claim 1, wherein the backups of the plurality of digital assets are performed in a manner that addresses issues of digital rights management.

4. The method of claim 3, wherein digital rights management is directed to protecting digital assets and controlling the distribution and usage of those digital assets.

5. The method of claim 4, wherein digital rights management is directed to how data can be backed up, copied, or edited on a mobile device.

6. The method of claim 1, wherein the plurality of digital assets include audio digital assets, video digital assets, software, graphics digital assets, or combinations thereof.

7. The method of claim 1, wherein the plurality of digital assets are downloaded from a website in an unencrypted form.

8. The method of claim 7, wherein the downloads of the plurality of digital assets are subject to licensing terms, wherein the licensing terms are directed to digital rights management.

9. The method of claim 1, wherein the backups are created such that the backups are not capable of being viewed or played on another mobile device without a restore operation being performed.

10. The method of claim 1, wherein the backups are created such that the backups are not capable of being viewed or played on the mobile device without a restore operation being performed.

11. The method of claim 10, wherein the restore operation conforms to digital rights management licensing terms stipulated by the owners of the plurality of digital assets.

12. The method of claim 10, further comprising the step of performing a restore operation in order to restore to the mobile device a digital asset lost due to a mobile device malfunction.

13. The method of claim 10, further comprising the step of performing a restore operation automatically upon power up of the mobile device.

14. The method of claim 10, wherein another electronic device uses one of the digital asset backups in order to load a digital asset onto the other electronic device.

15. The method of claim 14, wherein the loading of the digital asset onto the other electronic device conforms to digital rights management licensing terms stipulated by the owner of the digital asset.

16. The method of claim 14, wherein the mobile device designates which other electronic devices are permitted to use the digital asset backups in order to acquire digital assets.

17. The method of claim 1, wherein the creating of a digital asset backup is automatically performed upon download of a digital asset to the mobile device.

18. The method of claim 1, wherein the backups are stored on a remote computer system, wherein the remote computer system includes means for recovering the backup for use on the mobile device.

19. The method of claim 1, wherein the backups are stored on the mobile device.

20. The method of claim 1, wherein a digital asset backup is stored both on a remote computer system and on the mobile device.

21. The method of claim 1, wherein information specific to the mobile device is used to create an encrypted version of a digital asset.

22. The method of claim 21, wherein the information includes the mobile device'"'"'s SIM (subscriber identity module) card information.

23. The method of claim 21, wherein the information includes the mobile device'"'"'s IMSI (International Mobile Subscriber Identity) number.

24. The method of claim 21, wherein the information includes the mobile device'"'"'s IMEI (International Mobile Equipment Identity) number.

25. The method of claim 1, wherein secret data stored on a company infrastructure server is used to create an encrypted version of a digital asset.

26. The method of claim 1, further comprising the step for creating encrypted versions of the digital assets.

27. The method of claim 1, further comprising the step of using a secure interface that is interposed between a digital asset and an application which requires activation of the digital asset;

wherein the application is not permitted to access the digital asset directly but may access the digital asset through the secure interface.

28. The method of claim 1, wherein the digital asset backups are used in handling group distribution of data.

29. The method of claim 1, wherein the mobile device is a handheld wireless mobile communications device.

30. The method of claim 1, wherein the mobile device is a notebook computer.

31. The method of claim 1, wherein the mobile device is a personal digital assistant (PDA).

32. A data signal that is transmitted using a communication channel, wherein the data signal includes the backups of claim 1.

33. The data signal of claim 32, wherein the communication channel is a network, wherein the data signal is packetized data that is transmitted through a carrier wave across the network.

34. Computer-readable medium capable of causing a mobile device to perform the method of claim 1.

35. A method for handling a plurality of digital assets on a mobile device, comprising the steps of:

creating backups of the plurality of digital assets by automatically storing, on the mobile device, references to locations where the plurality of digital assets are accessible;

wherein the locations are remote locations with respect to the mobile device;

accessing one of the stored references in order to restore a digital asset for use on the mobile device.

36. The method of claim 35, wherein the references to locations are address locations for locating the digital assets on a network.

37. The method of claim 36, wherein the references are Uniform Resource Locator (URL) links.

38. The method of claim 37, wherein the links as backups are stored remotely from the mobile device.

39. The method of claim 37, wherein the links as backups are stored locally on the mobile device.

40. The method of claim 37, wherein the links as backups are stored remotely from the mobile device and are stored locally on the mobile device.

41. The method of claim 37, further comprising the step of using one of the links to restore the digital asset to the mobile device.

42. The method of claim 37, further comprising the step of using one of the links to provide the digital asset to another mobile device.

43. A mobile device that handles backups of digital assets, comprising:

a backup module that is configured to store backups of a plurality of digital assets in a backup data structure;

wherein the backup data structure is configured to store encrypted versions of the plurality of digital assets;

wherein the backup data structure is configured to be accessible by the mobile device in order to access the encrypted version of the digital asset stored in the backup data structure;
