A reference data verification method includes: matching first reference data representing biometric information registered for a registered user with second reference data representing the same type of biometric information as biometric information represented in the first reference data of the registered user registered before the first reference data, or third reference data generated based on the same type of biometric information as biometric information represented in the first reference data of the registered user at a time of a biometric authentication process to calculate a degree of similarity between biometric information represented in the first reference data and biometric information represented in the second or third reference data; and determining whether or not biometric information represented in the first reference data is biometric information of the registered user based on the degree of similarity. |
