Abstract

In a method for unlocking an object of an electronic device, an unlocking rule is preset to unlock the object. After movement signals are received from a touch screen of the electronic device, a quantity of segments displayed on the touch screen generated by the movement signals and a quantity of areas of the touch screen partitioned by the obtained segments are obtained. When a touch signal on one area of the obtained areas is received, a sequence number of the area from which the touch signal is received is calculated. The object of the electronic device is unlocked when the object is authorized to be unlocked according to the preset unlocking rule, the quantity of the obtained segments, the quantity of the obtained areas, and the sequence number of the area from which the touch signal is received.
