A device for recognizing a fingerprint, includes: a fingerprint sensor； at least two moisture detection electrodes disposed within a preset range of the fingerprint sensor； and a processing module coupled to the fingerprint sensor and the at least two moisture detection electrodes. The fingerprint sensor is configured to output a fingerprint signal to the processing module when a user touches the fingerprint sensor and the at least two moisture detection electrodes with a finger. The processing module is configured to acquire a characteristic value which is positively related to an impedance between the at least two moisture detection electrodes when the user touches the fingerprint sensor and the at least two moisture detection electrodes with the finger； determine a fingerprint recognition parameter which matches the characteristic value； and perform fingerprint recognition according to the determined fingerprint recognition parameter and the fingerprint signal.
