Claim 6:
7. An apparatus, comprising:
a touch screen;
a fingerprint sensor;
a memory configured to store instructions; and
one or more processors coupled to the touch screen, the fingerprint sensor, and the memory, wherein the instructions, when executed by the one or more processors, cause the apparatus to:
perform a first user authentication for unlocking the touch screen;
record a first time when the first user authentication succeeds;
detect a first input for executing an application program when the touch screen is unlocked, wherein the application program is configured to require a second user authentication for executing the application program, and wherein the first input is detected at a second time after the first time;
compare a time interval between the first time and the second time with a preset time threshold to detect whether the time interval is less than the preset time threshold or the time interval is greater than the preset time threshold;
start the application program without performing the second user authentication when the time interval is less than the preset time threshold and the first user authentication succeeds; and
lock the application program and require the second user authentication to start the application program when the time interval is greater than the preset time threshold.
