USER AUTHENTICATION PROCESSING APPARATUS USING A DISPOSABLE AUTHENTICATION CODE ISSUED BASED ON DISTRIBUTED AUTHENTICATION DATA AND OPERATING METHOD THEREOF

摘要

The present invention stores authentication data for a user in a client terminal and an authentication data storage server, and when a user authentication request is received from the client terminal, each authentication is distributed in the client terminal and the authentication data storage server. Collecting partial data of data to generate a one-time authentication code, and after transmitting the one-time authentication code to the client terminal, when the feedback data generated based on the one-time authentication code is received from the client terminal, the feedback data and the By performing authentication processing for the user through comparison between one-time authentication codes, a user authentication technique capable of enhancing security in the user authentication process can be provided.
