User authentication method and system using variable keypad and biometric authentication

摘要

Provided is a personal authentication method and system for transferring password position information from a portable terminal to a personal authentication server to prevent the outflow of the password and improving security. The present invention relates to a password and biometric information mixed personal authentication server, wherein a variable keypad including an encryption key and a biometric authentication key is generated, and each position of the encryption key and the position of the biometric authentication key are generated. A variable keypad generator for generating variable information, an authentication information storage unit for storing authentication information of a user using a mobile terminal, and the generated variable keypad information to a remote mobile terminal and received from the mobile terminal And an authentication execution unit that performs personal authentication by comparing the location information and biometric information of the encryption key according to the user input order with the authentication information stored in the authentication information storage unit.
