Abstract
An authentication system 10 of this invention includes an authentication station 20 having a directory server 24 and a biometrics collation server 30 capable of collating biometrics data based on the biological features of a user, and a user terminal 60 connected to the authentication station 20 via a network 12. The biometrics data is transmitted from the user terminal 60. In the authentication station 20, the biometrics collation server 30 collates biometrics data transmitted from a user with biometrics data registered in advance. The authentication station 20 can check validity of a digital certificate 66 by the directory server 24 and collates the biometrics data, thereby allowing personal authentication.
Claims20
An authentication station for authenticating a user connected to a network, characterized by comprising:
- digital certificate storage means for storing a digital certificate issued to the user and validity data representing validity of the digital certificate;
- registration data storage means for storing as registration data biometrics data based on a biological feature of the user;
- a collation server for collating biometrics data transmitted from the user with the registration data stored in said registration data storage means;
- and
- authentication means for determining the validity of the digital certificate of the user, for which authentication is demanded, on the basis of the validity data stored in said digital certificate storage means, and authenticating the user on the basis of a result of the validity determination and a collation result of said collation server.
An authentication method of causing an authentication station to authenticate a user connected to a network, characterized by comprising:
- the user registration step of causing the authentication station to issue a digital certificate to the user, storing the digital certificate and validity data representing validity of the digital certificate, acquiring biometrics data as a biological feature of the user from the user, and storing the biometrics data as registration data;
- the user validity determination step of causing the user to transmit the digital certificate to the authentication station and causing the authentication station to determine the validity of the digital certificate on the basis of the validity data;
- the biometrics data collation step of causing the user to acquire biometrics data and transmit the biometrics data to the authentication station, and causing the authentication station to collate the biometrics data transmitted from the user with the registration data;
- and
- the authentication step of authenticating the user on the basis of a result of the validation determination of the digital certificate and a collation result of the biometrics data.
