Abstract

A system for protecting data stored in a removable data storage device includes a personal electronic device, a removable solid state data storage device operatively coupled to the personal electronic device, and a circuit configured to protect data stored in the data storage device in response to detecting impending removal of the data storage device from the personal electronic device.

Claims

1. A system for protecting data stored in a removable data storage device, comprising:

a personal electronic device;

a removable solid state data storage device operatively coupled to the personal electronic device; and

a circuit configured to protect data stored in the data storage device by performing a protective action on the data using power from the personal electronic device in response to detecting impending removal of the data storage device from the personal electronic device;

wherein the protective action includes at least one of deleting the data, overwriting the data, encrypting the data, requiring a password, or hiding the data.

2. The system of claim 1, wherein the personal electronic device comprises at least one of a mobile phone, a smart phone, a personal digital assistant, and a pager.

3. The system of claim 1, wherein the personal electronic device comprises at least one of a personal computer, a laptop computer, a tablet computer, and a handheld computer.

4. The system of claim 1, wherein the personal electronic device comprises at least one of a camera and an audio recording device.

5. The system of claim 1, wherein the removable data storage device comprises a Subscriber Identity Module (SIM).

6. The system of claim 1, wherein the removable data storage device comprises at least one of a Secure Digital (SD) memory card, an integrated circuit (IC) memory, a Universal Serial Bus (USB) drive, a Universal Integrated Circuit Card (UICC), and a Removable User Identity Module (R-UIM).

7. The system of claim 1, wherein the circuit is disposed on the personal electronic device.

8. The system of claim 1, wherein the circuit is disposed on the data storage device.

9. The system of claim 1, wherein the circuit comprises a removal detection module, the removal detection module configured to detect impending removal of the data storage device.

10. The system of claim 1, wherein the circuit comprises a data protection module configured to perform the protective action.

11. A removable data storage device comprising:

a circuit configured to respond to detecting impending removal of the removable data storage device from a personal electronic device by performing a protective action on data stored in the removable storage device using;

wherein the protective action includes at least one of, deleting the data, overwriting the data, encrypting the data, requiring a password, or hiding the data.

12. The removable data storage device of claim 11, wherein the removable data storage device comprises a Subscriber Identity Module (SIM).

13. The removable data storage device of claim 11, wherein the removable data storage device comprises at least one of a Secure Digital (SD) memory card, an integrated circuit (IC) memory, a Universal Serial Bus (USB) drive, a Universal Integrated Circuit Card (UICC), and a Removable User Identity Module (R-UIM).

14. The removable data storage device of claim 11, wherein the circuit comprises a removal detection module, the removal detection module being configured to detect impending removal of the removable data storage device.

15. The removable data storage device of claim 11, wherein the circuit comprises a data protection module configured to perform the protective action.

16. A personal electronic device, comprising:

a circuit configured to protect data stored in a removable solid state data storage device by performing a protective action on the data using power from the personal electronic device in response to detecting impending removal of the data storage device from the personal electronic device;

wherein the protective action includes at least one of deleting the data, overwriting the data, encrypting the data, requiring a password, or hiding the data.

17. The personal electronic device of claim 16, wherein the personal electronic device comprises at least one of a mobile phone, a smart phone, a personal digital assistant, and a pager.

18. The personal electronic device of claim 16, wherein the personal electronic device comprises at least one of a personal computer, a laptop computer, a tablet computer, and a handheld computer.

19. The personal electronic device of claim 16, wherein the personal electronic device comprises at least one of a camera and an audio recording device.

20. The personal electronic device of claim 16, wherein the circuit comprises a removal detection module, the removal detection module configured to detect impending removal of the data storage device from the personal electronic device.

21. The personal electronic device of claim 20, wherein the removal detection module is configured to detect removal of a cover from the personal electronic device.

22. The personal electronic device of claim 20, wherein the removal detection module is configured to detect disruption of a magnetic link between the personal electronic device and the data storage device.
