Specially, the present invention prevents the reverse extraction of the password through the inference of a password generation method in advance by differently applying the password generation method to the generation of the password. In addition, the present invention improves the versatility of usage by being effectively applied to various systems provided on the Internet, a security system of various field, and the confirmation of electronic documents. Therefore, reliability and competitiveness in an internet authentication field, a security system field, and related fields are improved. |
