The apparatus greatly reduces the registered data amount and the
verification computation amount required for
user verification, in comparison with the
verification using image information itself, and also decreases the false
verification rate. The apparatus divides a biometric information image into cells, and extracts minutia information as well as
cell basic information from the individual cells. After comparison of
direction information of the individual cells of the registered data with
direction information of the individual cells of the to-be-verified data, thereby aligning the registered
fingerprint image and the to-be-verified
fingerprint image, the apparatus compares the minutia information of corresponding cells between the registered data and the to-be-verified data to make a match / non-match decision. Such an apparatus is applicable to systems that employ
pattern matching type image verification to perform
user verification utilizing biometric information such as fingerprints, palm prints,
blood vessel patterns, iris patterns, and facial images.
