PROBLEM TO BE SOLVED: To provide an individual verification device whose verification accuracy is enhanced. SOLUTION: An individual verification device 1 comprises a plurality of different biological feature checking parts, a checking score integrating process part 12, a checking score vector identification process part 13, and a verification result processing part 14. The checking score integrating process part 12 integrates individual checking scores to create a checking score vector where the total number of checking scores for each biological feature checking part equals the number of dimensions. The checking score vector identification process part 13 identifies the checking scores in accordance with predetermined identification rules in a checking score vector space. The checking scores are classified into either a 'valid' or 'invalid' category, and the verification result processing part 14 performs integral verification on the basis of the result of classification into the categories done by the checking score vector identification process part 13. |
