Biometric authentication apparatus, biometric authentication system, and biometric authentication method

A biometric authentication system comprising:

• a biometric authentication apparatus including
• a reading sensor configured to acquire first matching authentication characteristics data being unique to a first hand and used for matching, and second matching authentication characteristics data being unique to a second hand and used for matching, and
• a communications part configured to transmit the first and second matching authentication characteristics data and to receive successful authentication;
• and
• a server including
• a server communications part configured to receive the first matching authentication characteristics data and the second matching authentication characteristics data transmitted from the communications part of the biometric authentication apparatus,
• a storage configured to save first registration authentication characteristics data unique to the first hand, and second registration authentication characteristics data unique to the second hand, and
• a matching part configured to determine authentication as being successful upon detecting a result indicating that the first registration authentication characteristics data matches the first matching authentication characteristics data in a predetermined range, and the second registration authentication characteristics data matches the second matching authentication characteristics data in a predetermined range,
• wherein the server communications part transmits the successful authentication to the communications part of the biometric authentication apparatus.

A biometric authentication method comprising:

• causing a reading sensor to acquire first matching authentication characteristics data being unique to a first hand and used for matching, and second matching authentication characteristics data being unique to a second hand and used for matching;
• causing an apparatus to transmit the first and second matching authentication characteristics data from the reading sensor, and causing a server to receive the first and second matching authentication characteristics data transmitted by the apparatus;
• causing the server to determine whether first registration authentication characteristics data unique to the first hand matches the first matching authentication characteristics data in a first predetermined range;
• causing the server to determine whether second registration authentication characteristics data unique to the second hand matches the second matching authentication characteristics data in a second predetermined range;
• and
• causing the server to transmit successful authentication to the apparatus, upon detecting a result indicating that the first registration authentication characteristics data matches the first matching authentication characteristics data in the first predetermined range, and the second registration authentication characteristics data matches the second matching authentication characteristics data in the second predetermined range.
