Claim:
A fingerprint authentication apparatus comprising: a first sensor configured to acquire first fingerprint data from a user; a second sensor configured to acquire second fingerprint data that is different from the first fingerprint data; and a control unit configured to determine whether or not to authenticate the user based on similarities obtained from the comparison of each of the first fingerprint data and the second fingerprint data with registered fingerprint data, wherein the control unit is configured to determine whether or not to authenticate the user based on a combined score that is acquired by normalizing the sum of the product of a first score and a quality value of the first fingerprint data and the product of a second score and a quality value of the second fingerprint data wherein the first score is obtained from the similarity between the acquired first fingerprint data and the registered fingerprint data and the second score is obtained from the similarity between the acquired second fingerprint data and the registered fingerprint data.
