The invention discloses a mobile terminal. The mobile terminal comprises a judgment module, a first determination module and a second determination module; the judgment module is used for judging whether user identities corresponding to touch operations on the mobile terminal are legal or not when the mobile terminal is in a screen-on state and sequentially recording judgment results; the first determination module is used for determining whether the mobile terminal meets the security operation conditions or not when the mobile terminal is in the screen-on state according to the judgment results; if the mobile terminal meets the security operation conditions when the mobile terminal is in the screen-on state, the second determination module is used for determining that unlocking is conducted by adopting a first fingerprint unlocking rule when the mobile terminal enters the screen-on state from a screen-off state next time, and otherwise, unlocking is conducted by adopting a second fingerprint unlocking rule. The invention further discloses a processing method for fingerprint unlocking. Accordingly, the time for unlocking a screen of the mobile terminal can be shortened, and the efficiency of unlocking the screen of the mobile terminal is improved.
