In a specific implementation, the screen lock execution unit 14 executes a screen lock operation on the terminal according to the obtained lock screen control information. According to the obtained lock screen control information, the lock screen operation is performed on the terminal. In this embodiment, the lock screen method can also be applied to the unlocking situation, and the unlocking operation type is judged by the input duration of the unlocking fingerprint, so as to realize terminal unlocked.

With the embodiment of the present invention, when a fingerprint lock screen request for a terminal is detected, the input lock screen fingerprint and the input duration of the lock screen fingerprint can be obtained, and a level control corresponding table can be preset to obtain according to the fingerprint level. The lock screen control information relative to the fingerprint level, in order to verify user rights, by judging whether the lock screen fingerprint is a preset legal fingerprint, if the lock screen fingerprint is a preset legal fingerprint, then it can be based on the preset The level control correspondence table determines the fingerprint input duration threshold range where the input duration of the lock screen fingerprint is located, and determines the fingerprint level determined by the fingerprint input duration threshold range as the fingerprint level to which the lock screen fingerprint belongs, and then Obtain the corresponding lock screen control information according to the fingerprint level of the lock screen fingerprint, and perform the lock screen operation on the terminal according to the acquired lock screen control information, and improve the terminal control by judging whether the lock screen fingerprint is a preset legal fingerprint. Operational security, obtain different lock screen control information through the input time of the lock screen fingerprint without other selection operations, which reduces the complexity of user operations, and obtains the lock screen control information according to the input time, avoiding manual setting of the lock It simplifies the process of terminal lock screen control and improves the flexibility of terminal lock screen control.

Those of ordinary skill in the art can understand that all or part of the processes in the methods of the above embodiments can be implemented through computer programs to instruct related hardware, and the programs can be stored in a computer-readable storage medium. During execution, it may include the processes of the embodiments of the above-mentioned methods. Wherein, the storage medium may be a magnetic disk, an optical disk, a read-only memory (Read-Only Memory, ROM) or a random access memory (Random Access Memory, RAM) and the like.

The above disclosures are only preferred embodiments of the present invention, and certainly cannot limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
