BIOMETRIC AUTHENTICATION APPARATUS, ORGANISM AUTHENTICATION METHOD, AND ORGANISM AUTHENTICATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To enhance resistance to brute force attack.;SOLUTION: The biometric authentication apparatus is configured to carry out the following steps: dividing an organism image of a person to be authenticated into plural areas; extracting plural pieces of feature information from each of the plural areas; calculating plural complexities of each of the plural areas; adding plural number of sequences of a length depending on each of the plural complexities to each of plural pieces of feature data representing the plural pieces of feature information; to thereby generate a piece of verification data.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
