USER AUTHENTICATION SYSTEM, USER AUTHENTICATION APPARATUS, SMART CARD, AND USER AUTHENTICATION METHOD FOR UBIQUITOUS AUTHENTICATION MANAGEMENT

摘要

Disclosed are a user authentication system, a user authentication apparatus, a smart card, and a user authentication method for ubiquitous authentication management. The user authentication system for ubiquitous authentication management comprises: a certificate-issuing server which issues a certificate matching the biometric information of a registered subscriber; a smart card which stores biometric information of the subscriber as well as the certificate issued by the certificate-issuing server, receives biometric information from a user, compares the received data with the stored biometric information of the subscriber, and generates a tunneling start signal if the biometric information inputted by the user matches the biometric information of the subscriber; a service-providing server which provides various services for the user authenticated on the basis of the certificate issued by the certificate-issuing server; and a terminal which is connected to the smart card in a wired or wireless manner, and which establishes a VPN between the smart card and the service-providing server in correspondence to the tunneling start signal received from the smart card, and which transmits, to the service-providing server via the established VPN, authentication information in accordance with the certificate.
