Authentication System and Authentication Method
First Claim
1. An authentication system comprising:
- at least one portable terminal;
at least one authentication terminal; and
at least one authentication server;
wherein the at least one authentication server;
provides information necessary for authentication to the at least one authentication terminal,carries out user authentication of at least one user who performs at least one operation at the at least one authentication terminal while using the at least one portable terminal,has a storage unit that stores, in associated fashion and separately for each of the at least one user, at least one password generation user identifier for generating at least one one-time password;
wherein the at least one portable terminal has;
at least one storage unit that stores the at least one password generation user identifier,at least one password generating unit that encrypts information including the at least one password generation user identifier and that generates the at least one one-time password,at least one encoding unit that encodes the at least one one-time password and generates at least one baseband signal,at least one carrier wave generating unit that generates at least one carrier wave in at least one audible band,at least one modulating unit that uses the at least one baseband signal to modulate the at least one carrier wave and generate at least one modulated signal, andat least one speaker that transmits the at least one modulated signal as at least one sound wave; and
wherein the at least one authentication terminal has;
at least one microphone that receives the at least one sound wave, andat least one terminal authentication unit that carries out user authentication based on at least one result of comparison of the at least one one-time password which is obtained by demodulating and decoding the at least one sound wave received thereby, and at least one authentication one-time password which is directly generated from the at least one password generation user identifier stored in the storage unit of the at least one authentication server.

Abstract
An authentication system 1 that uses sound to transmit one-time password(s) may be equipped with portable terminal(s) 10, authentication terminal(s) 30, and authentication server(s) 50. Portable terminal 10 may be equipped with password generating unit(s) 21 which encrypt information including password generation user identifier(s) issued by authentication server(s) 50 and generate one-time password(s), encoding unit(s) 22 which encode one-time password(s) and generate baseband signal(s), carrier wave generating unit(s) 23 which generate carrier wave(s) in audible band(s), modulating unit(s) 25 which use baseband signal(s) to modulate carrier wave(s) and generate modulated signal(s), and speaker(s) 17 which transmit modulated signal(s) in the form of sound wave(s). One-time password(s) may be input as sound wave(s) from portable terminal(s) 10 to authentication terminal(s) 30.

19. In the context of an authentication system that is equipped with at least one portable terminal, at least one authentication terminal, and at least one authentication server which provides information necessary for authentication to the at least one authentication terminal, an authentication method for carrying out user authentication of at least one user who performs at least one operation at the at least one authentication terminal while using the at least one portable terminal, the authentication method comprising:
-
at least one password generating operation taking place at the at least one portable terminal in which information including at least one password generation user identifier is encrypted and at least one one-time password is generated; at least one encoding/modulating operation taking place at the at least one portable terminal in which the at least one one-time password is encoded and at least one baseband signal is generated, the at least one baseband signal is used to modulate at least one carrier wave in at least one audible band, and at least one modulated signal is generated; at least one transmitting operation in which the at least one modulated signal is transmitted as at least one sound wave from at least one speaker of the at least one portable terminal; at least one receiving operation in which the at least one sound wave is received by at least one microphone at the at least one authentication terminal; at least one demodulating/decoding operation taking place at the at least one authentication terminal and/or the at least one authentication server in which the at least one received sound wave is demodulated and decoded to reconstitute the at least one one-time password; at least one authentication one-time password generation operation taking place at the at least one authentication terminal and/or the at least one authentication server in which at least one authentication one-time password is directly generated from the at least one password generation user identifier stored at the at least one authentication server; and at least one authentication operation taking place at the at least one authentication terminal and/or the at least one authentication server in which the at least one reconstituted one-time password and the at least one authentication one-time password are compared to carry out user authentication.
