A fingerprint recognition method applied to a mobile terminal, wherein a screen of the mobile terminal comprises a fingerprint recognition module, wherein the method comprises: recognizing (101, 201), if a touch operation on the screen of the mobile terminal is detected, a touch area, on which the touch operation is performed, of the screen of the mobile terminal; controlling, if it is detected that the mobile terminal is in a state for fingerprint authentication, a brightness value of the touch area to be greater than or equal to a first preset brightness value, and a brightness value of a display area other than the touch area of the screen of the mobile terminal to be less than the first preset brightness value; and collecting (103, 203) and recognizing fingerprint information of the touch area by using the fingerprint recognition module; characterized in that the state for fingerprint authentication comprises a screen lock state, and the controlling, if it is detected that the mobile terminal is in a state for fingerprint authentication, a brightness value of the touch area to be greater than or equal to a first preset brightness value, and a brightness value of a display area other than the touch area of the screen of the mobile terminal to be less than the first preset brightness value comprises: if it is detected that the mobile terminal is in the screen lock state and a brightness value of the entire screen of the mobile terminal is a maximum value, controlling the brightness value of the touch area to be maintained as the maximum value, and controlling the brightness value of the entire display area other than the touch area of the screen of the mobile terminal to be decreased to be a second preset brightness value from the maximum value, and reducing a gray scale of a display interface of the screen of the mobile terminal through superimposing a transparent layer on the display interface of the screen of the mobile terminal, wherein the second preset brightness value is 20% or 50% of the maximum screen brightness value. recognizing (101, 201), if a touch operation on the screen of the mobile terminal is detected, a touch area, on which the touch operation is performed, of the screen of the mobile terminal; controlling, if it is detected that the mobile terminal is in a state for fingerprint authentication, a brightness value of the touch area to be greater than or equal to a first preset brightness value, and a brightness value of a display area other than the touch area of the screen of the mobile terminal to be less than the first preset brightness value; and collecting (103, 203) and recognizing fingerprint information of the touch area by using the fingerprint recognition module; characterized in that the state for fingerprint authentication comprises a screen lock state, and the controlling, if it is detected that the mobile terminal is in a state for fingerprint authentication, a brightness value of the touch area to be greater than or equal to a first preset brightness value, and a brightness value of a display area other than the touch area of the screen of the mobile terminal to be less than the first preset brightness value comprises: if it is detected that the mobile terminal is in the screen lock state and a brightness value of the entire screen of the mobile terminal is a maximum value, controlling the brightness value of the touch area to be maintained as the maximum value, and controlling the brightness value of the entire display area other than the touch area of the screen of the mobile terminal to be decreased to be a second preset brightness value from the maximum value, and reducing a gray scale of a display interface of the screen of the mobile terminal through superimposing a transparent layer on the display interface of the screen of the mobile terminal, wherein the second preset brightness value is 20% or 50% of the maximum screen brightness value.
