摘要

PURPOSE: A method for issuing a certificate using living body information in a public key infrastructure authenticating system is provided to directly issue a certificate without inputting a complex approval code and improve a security of a certificate issuing procedure. CONSTITUTION: A certificate issuing request message is received from a user system, which connects to an authentication system through the Internet(S500). A reference number and living body information of the corresponding user are extracted for a user authentication(S502). It is checked whether the transmitted living body information of the user is identified with living body information of a member registration user corresponded to a reference number registered and stored in a database storage(S504). If the living body information is identified with the registered living body information, an approval code of the user is created and supplied to the user system(S510). A public key created from the user system is received(S516) and a certificate is issued(S524).
