Abstract

The present disclosure discloses a fingerprint recognition method and apparatus, and a mobile terminal, which are related to the field of information recognition technologies, and are used to reduce power consumption of the mobile terminal while implementing timely fingerprint collection. According to embodiments of the present disclosure, the mobile terminal determines a first fingerprint recognition area of a touchscreen according to a first user interface, and detects a touch operation of a user on the touchscreen; activates a fingerprint recognition function of the first fingerprint recognition area when a touch position corresponding to the touch operation is located in the first fingerprint recognition area, and obtains corresponding first fingerprint information according to the touch operation; and executes at least one function when the first fingerprint information matches preset fingerprint information.

detecting a touch operation of a user on the touchscreen;

activating a fingerprint recognition function of the first fingerprint recognition area when a touch position corresponding to the touch operation is located in the first fingerprint recognition area, and obtaining corresponding first fingerprint information according to the touch operation; and

executing the at least one function when the first fingerprint information matches preset fingerprint information.

2. The fingerprint recognition method according to claim 1, wherein the at least one object is a first control of a first application program.

3. The fingerprint recognition method according to claim 2, wherein determining a first fingerprint recognition area of a touchscreen according to a first user interface comprises:

determining a first fingerprint recognition area corresponding to the first control according to a first user interface of the first application program, wherein the first user interface is an interface that displays at least the first control.

4. The fingerprint recognition method according to claim 2, wherein before determining a first fingerprint recognition area of a touchscreen according to a first user interface, the method further comprises:

receiving user input, wherein the user input is used to set fingerprint recognition for the at least one function corresponding to the first control.

5. The fingerprint recognition method according to claim 1, wherein determining a first fingerprint recognition area of a touchscreen according to a first user interface comprises:

determining a first fingerprint recognition area corresponding to the first control according to a type of the first control, wherein the type is a type that requires fingerprint recognition.

6. The fingerprint recognition method according to claim 2, wherein:

the first application program is a desktop management application program, the first control is an identifier of a second application program, and the at least one function is to start the second application program.

7. The fingerprint recognition method according to claim 2, wherein:

the first application program is a non-desktop management application program, the first control is any button of the non-desktop management application program, and the at least one function is to start a function corresponding to the any button.

8. The fingerprint recognition method according to claim 4, wherein after receiving user input, the method further comprises:

adding a specific identifier to the first control, wherein the specific identifier is used to indicate that fingerprint recognition needs to be performed to execute the at least one function.

9. The fingerprint recognition method according to claim 1, wherein after activating a fingerprint recognition function of the first fingerprint recognition area when a touch position corresponding to the touch operation is located in the first fingerprint recognition area, and obtaining corresponding first fingerprint information according to the touch operation, the method further comprises:

disabling the fingerprint recognition function when the first fingerprint information matches the preset fingerprint information.

10. The fingerprint recognition method according to claim 9, further comprising:

disabling the fingerprint recognition function when the first fingerprint information does not match the preset fingerprint information, and no user fingerprint information is detected in a first predetermined time;

or

disabling the fingerprint recognition function when the first fingerprint information does not match the preset fingerprint information, and any user fingerprint information detected in a second predetermined time is inconsistent with the preset fingerprint information;

or

disabling the fingerprint recognition function when the first fingerprint information does not match the preset fingerprint information, and a quantity of verification errors is larger than a quantity threshold;

or

disabling the fingerprint recognition function when the first fingerprint information does not match the preset fingerprint information and it is detected that the user touches a non-fingerprint recognition area, wherein the non-fingerprint recognition area is an area except the first fingerprint recognition area.
