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 card 200 having a card application 210 and a card application 220, and a terminal device 100 that can communicate with the IC card 200. The card application 210 compares authentication information inputted by a user and transmitted from the terminal device and authentication information held by itself. The card application 210 stores authentication status information according to results of the comparison. The card application 220 acquires the authentication status information from the card application 210, stored in the IC card 200.
