<p>The present invention provides a fingerprint authentication unit and an authentication system which can use one apparatus having a fingerprint collation function to thereby manage and operate a plurality of types of apparatuses or applications. By the fingerprint authentication unit, fingerprint data of a plurality of fingers of the same person is registered and stored in an IC card section(30), so that a collation control section(12) compares and collates fingerprint data detected by a fingerprint sensor(14) with the registered fingerprint data at a requested collation level corresponding to a security level of the application and, when the user is authenticated, a common control section(11) obtains from a FACCT(13) a key necessary to access a file which stores therein data to be output corresponding to the contents of the application, which key is in turn decrypted with an encryption key of a MF at an IC Card CPU(21) and used to authorize access to the file in order to the data in this file to the application. <IMAGE></p> |
