Abstract
Disclosed is a mobile terminal including a touch screen display, a power button and an activation button for turning on the touch screen display. Upon detection of one-time pressing of the activation button while the touch screen display is turned off, the terminal is configured to turn on the touch screen display and perform a fingerprint authentication function in addition to turning on the touch screen display. The touch screen display displays a lock screen thereon as it is turned on in response to the detection of one-time pressing, and the lock screen is displayed on the touch screen display when the fingerprint authentication function is being performed. A lock state of the terminal continues when the fingerprint authentication function fails to authenticate a user, and the lock state is released for enabling other functions of the terminal when the fingerprint authentication function authenticates a user.
