Abstract
A method for controlling access to an electronic device, the electronic device displays an image on a display device of the electronic device, when the electronic device is locked. The electronic device obtains a pattern according to touch signals on the displayed image using an image-recognition algorithm. Once a similarity degree between the obtained pattern and a predetermined pattern is greater than or equal to a predetermined value, the electronic device is unlocked.
