Abstract

In some embodiments systems and methods are provided for protecting data stored locally on mobile telecommunications or personal information devices. Data may be protected from loss by an automatic backup procedure implemented on a predetermined schedule or in response to a trigger. Information stored on a lost or stolen portable information device may be rendered inaccessible in response to a protective action directive. Access to locally stored information may be denied while emergency telecommunications service remains active.

Claims

1. A system for protecting information from unauthorized access, the system comprising:

storage external to a mobile telecommunications device, the external storage encoding a backup of the information stored locally on the mobile telecommunications device; and

a communications interface operable to supply the mobile telecommunications device with a protective action directive via a wireless communication network, the protective action directive configured to trigger a functional sequence executable on the mobile telecommunications device to ensure that a current backup of the locally stored information has been transferred to the external storage and to thereafter render inaccessible the locally stored information.

2. The system of claim 1,

wherein the transfer of the information to the external storage is at least partially via the wireless communication network.

3. The system of claim 1,

wherein the external storage is maintained, at least in part, by a telecommunications service provider.

4. The system of claim 1,

wherein the external storage is maintained, at least in part, by a telecommunications service subscriber.

5. The system of claim 1, the system further comprising:

the mobile telecommunications device and a computer-readable encoding of the functional sequence executable thereon.

6. The system of claim 1, the system further comprising:

a communications interface operable to transfer to a designated mobile telecommunications device at least a partial copy of the backup.

7. The system of claim 1, the system further comprising:

a communications interface operable to supply a designated mobile telecommunications device with a restoration directive via a wireless communication network, the restoration directive configured to trigger a functional sequence executable on the designated mobile telecommunications device to ensure that a semantically equivalent copy of the externally stored information exists on an internal storage of the designated mobile telecommunications device and to restore access to the locally stored information.

8. A method for protecting information from unauthorized access, the method comprising:

receiving, via a wireless communication network, for storage external to a mobile telecommunications device, at least a partial copy of the information stored locally on the mobile telecommunications device; and

supplying, via a wireless communication network, the mobile telecommunications device with a protective action directive configured to cause the mobile telecommunications device to execute a protective action rendering the locally stored information inaccessible.

9. The method of claim 8, wherein the protective action includes one or more of:

deleting the information from local storage of the mobile communications device.

encrypting the information in the local storage; and

overwriting the information in the local storage.

10. The method of claim 8, further comprising:

receiving a restore directive; and

in response to the restore directive, transferring the externally stored information to a designated mobile telecommunications device.

11. The method of claim 8, further comprising:

receiving a restoration directive; and

in response to the restoration directive, ensuring that a semantically equivalent copy of the externally stored information exists on an internal storage of the designated mobile telecommunications device and restoring access to the locally stored information.

12. A mobile telecommunications device comprising:

local storage for encoding information of a subscriber;

a communications interface operable to receive a protective action directive via a wireless communication network; and

a functional sequence executable on the mobile telecommunications device in response to the protective action directive to ensure that a current backup of the information exists on storage external to the mobile telecommunications device and to thereafter render inaccessible the information encoded in the local storage.

13. The device of claim 12,

wherein the mobile telecommunications device retains telecommunications functionality after the functional sequence is executed.

14. The device of claim 12, further comprising:

a communications interface operable to receive a restoration directive via a wireless communication network; and

a functional sequence executable on the mobile telecommunications device in response to the restoration directive to ensure that at least a partial copy of the backup exists on storage internal to the mobile telecommunications device and to restore access to the information encoded in the local storage.

15. A method for protecting information from unauthorized access, the method comprising:

storing information locally on a mobile telecommunications device;

receiving a protective action directive via a wireless communication network;

ensuring that a current backup of the stored information exists on storage external to the mobile telecommunications device; and

in response to the received protective action directive, executing on the mobile telecommunications device a protective action in accordance with the protective action directive, the protective action rendering the stored information inaccessible.

16. The method of claim 15, wherein the ensuring comprises:

automatically transferring a copy of the stored information to the external storage via the wireless communications network.

17. The method of claim 15, wherein the ensuring comprises:

confirming that the mobile telecommunications device has been synchronized with a computer more recently than the stored information has been changed.

18. The method of claim 15, wherein the ensuring comprises:

comparing the stored information with the current backup stored in the external storage; and

confirming that the two representations of information are semantically equivalent.

19. The method of claim 15,

wherein the stored information comprises less than all information stored on the mobile telecommunications device.

20. The method of claim 19,

wherein one or both of the set of information for which the backup is ensured and the set of information which is rendered inaccessible are selectable by a user.

21. The method of claim 15, further comprising:

receiving a restoration directive; and

in response to the received restoration directive, executing on the mobile telecommunications device an action in accordance with the restoration directive, the action restoring access to the stored information.

22. A method for protecting information from loss, the method comprising:

storing information locally on a mobile telecommunications device;

receiving a protective action directive via a wireless communication network;

automatically ensuring that a current backup of the stored information exists on storage external to the mobile telecommunications device.

23. The method of claim 22,

wherein the ensuring occurs in conjunction with a verification process.

24. The method of claim 22,

wherein the ensuring occurs on a predetermined schedule.

25. The method of claim 22,

wherein the ensuring occurs in response to a trigger signal from the mobile telecommunications device.

26. The method of claim 25,

wherein the trigger signal is sent by the mobile telecommunications device on power up.

27. The method of claim 25,

wherein the trigger signal is sent by the mobile telecommunications device when the mobile telecommunications device encounters a low-battery condition.

28. The method of claim 25,

wherein the trigger signal is sent by the mobile telecommunications device when information stored on the mobile telecommunications device is altered.

29. The method of claim 25,

wherein the trigger signal is sent by the mobile telecommunications device in response to an attempt to access the stored information.

30. The method of claim 22, further comprising:

subsequent to the ensuring and in response to the received protective action directive, executing on the mobile telecommunications device a protective action in accordance with the protective action directive, the protective action rendering the stored information inaccessible.

31. The method of claim 22, further comprising:

requesting restoration of the backup; and

receiving at least a partial copy of the backup on a designated mobile telecommunications device.
