Abstract: A method of verifying a fingerprint includes selecting a feature point from among feature points of a fingerprint image, the selected feature point matching a registered feature point; determining a partial region of the fingerprint corresponding to the feature point in the fingerprint image; obtaining feature information of the partial region of the fingerprint in the fingerprint image; and verifying the fingerprint based on the feature information of the partial region in the fingerprint image.
