1. A personal authentication system using biometrics information comprising:
a registering apparatus including a first biometrics information inputting unit for obtaining biometrics information of a
person to be registered, said registering apparatus obtaining data for verification from information inputted using said first
biometrics information inputting unit and registering the same; and
an authenticating apparatus for determining whether a person, to be authenticated is a person registered by said registering
apparatus, based on said data for verification registered by said registering apparatus;
said registering apparatus further including,
a first extracting unit for extracting biometrics characteristic data from said biometrics information obtained by said first
biometrics information inputting unit, and registering said biometrics characteristic data as registry biometrics characteristic
data, for primary verification; and
a second extracting unit for extracting data, which is different from said registry biometrics characteristic data for primary
verification, from information inputted using said first biometrics information inputting unit, and registering said data
as registry data for secondary verification,
said authenticating apparatus further comprising:
a primary authenticator verifying whether a person to be authenticated is a person registered by said registering apparatus,
based on said data for primary verification registered by said first extracting unit of said registering apparatus, and
a secondary authenticator, when the secondary verification is required to be carried out according to a result of the primary
verification in said authenticating apparatus, verifying whether a person to be authenticated is a person registered by said
registering apparatus, based on the data for secondary verification registered by said second extracting unit of said registering
apparatus.
