Abstract

A mobile communications device for communicating with a wireless network is described. The device includes a processor, a communications sub-system connected to the processor for exchanging signals with the wireless network and with the processor, a user input device connected to the processor for sending user input signals to the processor in response to user inputs. A security module is associated with the processor for automatically taking a security action upon detecting a predetermined security user input through the user input device. The security action can include sending a duress message and/or wiping data stored on the device.

Claims

1. A method of providing security for data stored on a wireless communications device, the wireless communications device comprising a processor and a storage element operably connected to the processor, the storage element comprising service data required to establish communications with a wireless network and user application data associated with at least one application on the wireless communications device, the method comprising:

detecting an indication of a duress alarm at a user interface;

displaying a list of selectable items on a display screen related to the detected duress alarm;

detecting a selection of one of the list of selectable items;

displaying on the display screen a window comprising a prompt for further input at the user interface;

receiving, at the user interface, input related to the prompt for further input;

determining that the input has been received at the user interface within a specified time period subsequent to the displaying the prompt for further input; and

responsive to the determining, performing a security action comprising deleting at least a portion of the service data while encrypting at least a portion of the user application data stored on the storage element.

2. The method of claim 1, wherein displaying a list of selectable items comprises displaying selectable options of continuing with the security action or cancelling the security action.

3. The method of claim 1, further comprising inputting input at the user interface through one or more of a plurality of character input.

4. The method of claim 1, wherein the security action comprises deleting all the service data.

5. The method of claim 1, wherein the security action comprises encrypting all the service data.

6. The method of claim 1, wherein the security action comprises deleting all the user application data.

7. The method of claim 1, wherein the security action comprises encrypting all the user application data.

8. The method of claim 1, wherein the security action comprises erasing all service data and user application data stored on the storage element while maintaining other data stored on the storage element.

9. The method of claim 1, wherein the service data comprises data required to establish communications with a wireless gateway connected to the wireless network.

10. A wireless communications device comprising:

a processor; and

a storage element operably connected to the processor, the storage element storing service data required to establish communications with a wireless network and user application data associated with at least one application on the wireless communications device;

the processor being adapted to;

detect an indication of a duress alarm at a user interface;

display a list of selectable items on a display screen related to the detected duress alarm;

detect a selection of one of the list of selectable items;

display on the display screen a window including a prompt for a further input at the user interface;

receive, at the user interface, input related to the prompt for further input;

determine that the input has been received at the user interface within a specified time period subsequent to the displaying the prompt for further input; and

responsive to the determining, perform a security action including deleting at least a portion of the service data while encrypting at least a portion of the user application data stored on the storage element.

11. The wireless communications device of claim 10, wherein the processor is adapted to display the list of selectable items by displaying selectable options of continuing with the security action or cancelling the security action.

12. The wireless communications device of claim 10, the processor is further adapted to receive input at the user interface through one or more of a plurality of character inputs.

13. The wireless communications device of claim 10, wherein the processor is adapted to perform the security action by deleting all the service data.

14. The wireless communications device of claim 10, wherein the processor is adapted to perform the security action by encrypting all the service data.

15. The wireless communications device of claim 10, wherein the processor is adapted to perform the security action by deleting all the user application data.

16. The wireless communications device of claim 10, wherein the processor is adapted to perform the security action by encrypting all the user application data.

17. The wireless communications device of claim 10, wherein the processor is adapted to perform the security action by erasing all service data and user application data stored on the storage element while maintaining other data stored on the storage element.

18. The wireless communications device of claim 10, wherein the service data comprises data required to establish communications with a wireless gateway connected to the wireless network.

19. A non-transitory computer-readable medium containing computer-executable instructions that, when performed by a processor in a wireless communications device, the wireless communications device including a storage element operably connected to the processor, the storage element storing service data required to establish communications with a wireless network and user application data associated with at least one application on the wireless communications device, cause said processor to:

detect an indication of a duress alarm at a user interface;

display a list of selectable items on a display screen related to the detected duress alarm;

detect a selection of one of the list of selectable items;

display on the display screen a window including a prompt for a further input at the user interface;

receive, at the user interface, input related to the prompt for further input;

determine that the input has been received at the user interface within a specified time period subsequent to the displaying the prompt for further input; and

responsive to the determining, perform a security action including deleting at least a portion of the service data while encrypting at least a portion of the user application data stored on the storage element, wherein the security action is performed only if the further input is received at the user interface within a specified time period subsequent to receiving the prompt for a further input.
