CARDLESS DEBIT SETTLEMENT SYSTEM, METHOD, AND CONTROL PROGRAM THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a cardless debit settlement system that can authenticate a customer by biometric information and public key cryptography without using a card and a personal identification number.

SOLUTION: An authentication registration terminal 10 has a registration processing part 101 for accessing customer information provided by a customer information server 20 and editing the registered information, and a biometric information processing part 102 for receiving input biometric information about a customer and generating a secret key and a public key by public key cryptography, and registers only the public key. A settlement processing terminal 30 has a settlement processing part 301 for requesting authentication and executing settlement processing, and a biometric information processing part 302 for receiving input biometric information about a customer and generating a secret key and a public key. The biometric information processing parts 102 and 302 generate a unique key pair from a single biometric information input.
