Abstract
An electronic device can be unlocked by displaying, while the electronic device is in a locked state, on a touchscreen of the electronic device, line(s) dividing the touchscreen into input regions. Input gestures are detected on the touchscreen, and one of the input regions is identified as an input region containing the starting point of the input gesture. A base number is retrieved corresponding to the identified input region, and a numerical value of a password digit is calculated by using the base number and a numerical value corresponding to the input gesture. A sequence of thus calculated password digits is compared to a password stored within the electronic device, and the electronic device is unlocked following a match between the series of calculated password digits and the stored password.
