Abstract:
A method, system, and/or computer program product unlocks an electronic device that has a touchscreen. Multiple tactile inputs to a touchscreen on a locked electronic device are detected. A distance between the most distant tactile inputs is detected, and a relative position, as measured from the most distant tactile inputs, of other tactile inputs to the touchscreen is calculated. In response to the relative position of the other detected tactile inputs matching a stored positioning file for touchscreen tactile inputs, the electronic device is unlocked.
