A method for fingerprint identification, comprising: detecting whether the number of damaged pixel units in a fingerprint identification sensor reaches a preset threshold value or not, the damaged pixel unit referring to physically damaged pixel unit in the fingerprint identification sensor and being determined by determining whether a pixel feature of each of pixel units in a fingerprint image acquired by the fingerprint identification sensor in a preset photographic environment belongs to a value range corresponding to the pixel feature of the physically damaged pixel unit, wherein the pixel feature at least comprises a brightness value and/or a contrast; and if the number of the damaged pixel units reaches the preset threshold value, stopping matching identification of the fingerprint image acquired by the fingerprint identification sensor, wherein detecting whether the number of the damaged pixel units in the fingerprint identification sensor reaches the preset threshold value or not comprises: determining a coverage area of a fingerprint of a user in the fingerprint identification sensor according to the fingerprint image; and detecting whether the number of damaged pixel units in pixel units belonging to the coverage area reaches a first preset threshold value or not; and wherein the pixel feature acquired by a pixel unit is black when a high voltage is input into the fingerprint identification sensor and the pixel feature acquired by the pixel unit is white when a low voltage is input into the fingerprint identification sensor under a regular condition, in response to the pixel feature acquired by the pixel unit is white when the high voltage is input into the fingerprint identification sensor, the pixel unit is determined to be the physically damaged pixel unit. detecting whether the number of damaged pixel units in a fingerprint identification sensor reaches a preset threshold value or not, the damaged pixel unit referring to physically damaged pixel unit in the fingerprint identification sensor and being determined by determining whether a pixel feature of each of pixel units in a fingerprint image acquired by the fingerprint identification sensor in a preset photographic environment belongs to a value range corresponding to the pixel feature of the physically damaged pixel unit, wherein the pixel feature at least comprises a brightness value and/or a contrast; and if the number of the damaged pixel units reaches the preset threshold value, stopping matching identification of the fingerprint image acquired by the fingerprint identification sensor, wherein detecting whether the number of the damaged pixel units in the fingerprint identification sensor reaches the preset threshold value or not comprises: determining a coverage area of a fingerprint of a user in the fingerprint identification sensor according to the fingerprint image; and detecting whether the number of damaged pixel units in pixel units belonging to the coverage area reaches a first preset threshold value or not; determining a coverage area of a fingerprint of a user in the fingerprint identification sensor according to the fingerprint image; and detecting whether the number of damaged pixel units in pixel units belonging to the coverage area reaches a first preset threshold value or not; and wherein the pixel feature acquired by a pixel unit is black when a high voltage is input into the fingerprint identification sensor and the pixel feature acquired by the pixel unit is white when a low voltage is input into the fingerprint identification sensor under a regular condition, in response to the pixel feature acquired by the pixel unit is white when the high voltage is input into the fingerprint identification sensor, the pixel unit is determined to be the physically damaged pixel unit.
