Claim One:
1. A biometric information verifying apparatus which compares a registered biometric information image and a to-be-verified biometric information image input by a user at user verification, said apparatus comprising: a cell dividing unit which divides the to-be-verified biometric information image into cells; a cell basic information obtaining unit which obtains cell basic information from the individual cells that are obtained by said cell dividing unit, said cell basic information including direction information of the to-be-verified biometric information image contained in the individual cells; a cell feature information obtaining unit which obtains minutia information of the to-be-verified biometric information image, as cell feature information, from the individual cells that are obtained by said cell dividing unit; and a verifying unit which verifies the to-be-verified biometric information image against the registered biometric information image by comparison between registered data and to-be-verified data, said registered data including: (i) cell basic information obtained from individual cells making up the registered biometric information image, which cell basic information includes direction information of the registered biometric information image contained in the individual cells; and (ii) cell feature information obtained from the individual cells making up the registered biometric information image, which cell feature information includes minutia information of the registered biometric information image contained in the individual cells, and said to-be-verified data including the cell basic information and the cell feature information, which are obtained by said cell basic information obtaining unit and said cell feature information obtaining unit, respectively, said verifying unit, comparing the direction information of the individual cells of the to-be-verified biometric information image and the direction information of the individual cells of the registered biometric information image, and aligning the to-be-verified biometric information image and the registered biometric information image with each other, comparing at least the minutia information of corresponding cells between the to-be-verified data and the registered data to evaluate whether or not the comparison result satisfies a predetermined match condition, and if the comparison result satisfies the predetermined match condition, making a match decision, in which the to-be-verified biometric information image and the registered biometric information image are judged to belong to one and the same user.
