Detection of duress condition at a communication device
First Claim
1. A communication device, comprising:
- a touchscreen interface configured to detect contact applied at a touchscreen surface;
one or more force sensors configured to detect force applied at the touchscreen surface;
at least one processor in communication with the touchscreen interface and the one or more force sensors, the at least one processor being configured to;
detect contact indicative of input of a password at the touchscreen interface;
detect, by the one or more force sensors, a force of said contact above a predetermined threshold and set a duress flag upon detection that the force of said contact is above the predetermined threshold;
identify a duress condition at the communication device upon determining that the input password corresponds to a previously stored password when the duress flag is set.

Abstract
A communication or computing device having a touchscreen interface is adapted to detect a duress condition upon user access through input of a gesture-based password or authentication code. One or more force sensors are provided for detection of force applied at the touchscreen surface, and interoperate with processing elements to detect input of a gesture-based password through contact at the touchscreen interface; determine that force detected by at least one of the force sensors during input of the password exceeds a predefined threshold; and compares the input password with previously stored information to determine that the input password substantially corresponds to the previously stored information. If the input password substantially corresponds to the previously stored information and the detected pressure exceeds the threshold, a duress condition is determined for the device.

10. A method of detecting a duress condition at a communication device comprising a touchscreen interface, the method comprising:
-
detecting contact indicative of input of a password at the touchscreen interface; detecting a force of said contact above a predetermined threshold and setting a duress flag upon detecting said force of said contact; and identifying a duress condition at the communication device upon determining that the input password corresponds to a previously stored password when said duress flag is set. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A computer program product comprising a non-transitory computer-readable medium storing program code which, when executed at a communication device comprising a touchscreen configured to detect contact at the touchscreen and one or more force sensors configured to detect an applied force at the touchscreen, causes the communication device to carry out the method of:
-
detecting contact indicative of input of a password at the touchscreen interface; detecting a force of said contact above a predetermined threshold during said contact and setting a duress flag upon detecting said force of said contact; and identifying a duress condition at the communication device upon determining that the input password corresponds to a previously stored password when said duress flag is set.
