<p>A biometric information processing apparatus includes: a biometric information acquiring unit which acquires biometric input data representing user's biometric information; and a processing unit. The processing unit implements: a feature quantity extracting function which extracts a feature quantity characterizing a feature of the biometric information from the biometric input information represented by the biometric input data; a classifying function which classifies, based on the extracted feature quantity, the biometric input information represented by the biometric input data into at least one of a plurality of classes categorized according to common features of biometric information, and which computes a confidence level for each class into which the biometric input information has been classified; a classification result judging function which judges whether or not a maximum value of the confidence level is larger than a threshold value predefined for the class corresponding to the maximum value among the plurality of classes; and a guidance function which, if the maximum value of the confidence level is not larger than the threshold value, prompts the user to have the user's biometric information reacquired by the biometric information acquiring unit.</p> |
