Patent ID: 7836513

Claim:
A system for secure input for a mobile device comprising: a input device for receiving an input from a user, the input device having a keypad having a plurality of alphabetic keys; a sensor for determining an status of the mobile device, wherein the sensor is a tilt sensor; and a processor in operable communication with the input device and the sensor, wherein the processor provides a secure input to the mobile device by altering the input received from the user responsive to the status of the mobile device sensed by the tilt sensor; wherein the processor translates an entered keystroke to a translated keystroke in response to a degree of tilt of the mobile device, wherein a tilt of less than a first degree value results in no translation of the entered keystroke, a tilt equal to the first degree value and less than a second degree value results in translating the entered keystroke by one key along the keypad in the direction of tilt and a tilt equal to or greater than the second degree value results in translating the entered keystroke by two keys along the keypad in the direction of tilt.
