ABSTRACT:
A authentication method which can provide a card application that does not depend on the presence of an authentication information comparison system and can also improve security and simplify authentication information management. An authentication system to which the authentication method is applied is comprised of an IC card200having a card application210and a card application220, and a terminal device100that can communicate with the IC card200. The card application210compares authentication information inputted by a user and transmitted from the terminal device and authentication information held by itself. The card application210stores authentication status information according to results of the comparison. The card application220acquires the authentication status information from the card application210, stored in the IC card200.
