Biometrics authentication system and method

A biometrics authentication method, comprising:

• inputting information for authenticating a user;
• authenticating the user by a method other than biometrics authentication;
• registering and storing biometrics data on the user;
• conducting biometrics authentication;
• determining whether or not it is possible to conduct the biometrics authentication by referring to the stored biometrics data;
• and
• outputting an authentication result as to whether the user is authenticated,
• wherein, only in a case where the user is authenticated in the operation of authenticating the user by a method other than the biometrics authentication, the biometrics data on the user is registered and stored, and
• only in a case where it is determined that it is possible to conduct the biometrics authentication, the biometrics authentication is further conducted.

A recording medium storing a computer-executable program for realizing a biometrics authentication method, the program comprising the operations of:

• inputting information for authenticating a user;
• authenticating the user by a method other than biometrics authentication;
• registering and storing biometrics data on the user;
• conducting biometrics authentication;
• determining whether or not it is possible to conduct the biometrics authentication by referring to the stored biometrics data;
• and
• outputting an authentication result as to whether the user is authenticated,
• wherein, only in a case where the user is authenticated in the operation of authenticating the user by a method other than the biometrics authentication, the biometrics data on the user is registered and stored, and
• only in a case where it is determined that it is possible to conduct the biometrics authentication, the biometrics authentication is further conducted.
