Abstract
A personal authentication system using biometrics information. The system orders, when an characteristic element in the biometrics information (such as a characteristic point in a fingerprint) can be expressed with two types of information (such as, for instance, a coordinate values for a characteristic point in a fingerprint and a local partial image), the characteristic points using one type of information (for instance, local partial image) as label information, and outputs other type of information (such as coordinate values) as key information according to the order.
