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 providing power from the personal electronic device to the data storage device in response to detecting impending removal of the data storage device from the personal electronic device.

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 protect at least some of the data stored in the data storage device.

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 providing power to the data storage device to protect data stored in the removable data storage device.

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 protect at least some of the data stored in the removable data storage device.

16. A personal electronic device, comprising:

a circuit configured to protect data stored in a removable solid state data storage device by providing power from the personal electronic device to the data storage device in response to detecting impending removal of the data storage device from the personal electronic device.

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.
