Abstract:
1. An authentication apparatus, comprising: a biometric information input unit inputting biometric information; an extraction unit extracting biometric feature information from the input biometric information; an estimation unit estimating matching precision of the extracted biometric feature information; a request unit requesting an input of additional authentication information different from the input biometric information when said estimation unit estimates that a predetermined matching precision cannot be obtained; an authentication unit information input unit inputting the authentication information; a biometric feature information registration unit preliminarily storing registered biometric feature information; an authentication information registration unit preliminarily storing additional registered authentication information; a biometric feature information matching check unit having a matching check between the extracted biometric feature information and the registered biometric feature information; an authentication information matching check unit having a matching check between the input authentication information and the registered authentication information; and a determination unit computing matching precision by combining a matching check result about biometric feature information with a matching check result about additional authentication information, and determining based on a computation result whether or not a user is authenticated.
