SYSTEM AND METHOD FOR AUTHENTICATION USING QUICK RESPONSE CODE
First Claim
Patent Images
1. An authentication system using a Quick Response (QR) code, comprising:
- a computer terminal for making an authentication request by transmitting a QR code authentication request signal including both user identification information of a user and authentication scheme selection information required to select at least QR code authentication, and for displaying a QR code image received in response to the authentication request;
a portable authentication terminal for scanning the QR code image and transmitting QR code information contained in the QR code image;
a legacy authentication server for requesting generation of a QR code by transmitting a QR code generation request signal, in which QR code generation information including the user identification information is contained, via QR code authentication selected using the authentication scheme selection information for a certain service when the authentication request is made, for transmitting a QR code image received in response to the request to the computer terminal, and for approving provision of the service when received results of QR code authentication indicate success; and
a QR authentication server for generating QR code information when the QR code generation request signal is received, generating a QR code image for the QR code information, providing the QR code image to the legacy authentication server, comparing the QR code information received from the portable authentication terminal with QR code information that is generated for the QR code image and is stored in a QR code generation database (DB), performing authentication based on whether pieces of QR code information match each other, and notifying the legacy authentication server of the results of the QR code authentication.

Abstract
Provided is a system and method for authenticating a user according to login and financial transactions, such as payment and transfer, and more particularly, to a system and method for authentication using a quick response (QR) code, in which a quick response (QR) code including authentication information is displayed on the computer terminal of a user, the QR code is scanned through a smart device such as a smartphone, and the authentication is performed using the scanned QR code by accessing a QR authentication server included in the QR code.

15. An authentication method using a Quick Response (QR) code, comprising:
-
an authentication request procedure of, while a computer terminal is using a certain service provided by a service server, requesting authentication by transmitting a QR code authentication request signal including at least user identification (ID) information and authentication scheme selection information, required to select at least QR code authentication, to a legacy authentication server; a QR code generation request procedure of, when an authentication request is made in response to reception of a QR code authentication request signal including the authentication scheme selection information required to select QR code authentication from the computer terminal, transmitting, by the legacy authentication server, a QR code generation request signal, which includes QR code generation information including the user ID information, to the QR authentication server, thus requesting generation of a QR code; a QR code image generation procedure of, when the QR authentication server receives the QR code generation request signal from the legacy authentication server, collecting QR code information in response to the authentication request, generating a QR code image for the collected QR code information, and providing the QR code image to the legacy authentication server; a QR code provision procedure of transmitting, by the legacy authentication server, the QR code image to the computer terminal; a QR code display procedure of receiving and displaying, by the computer terminal, the QR code image; a QR code scan procedure of scanning, by a portable authentication terminal, the QR code image displayed on the computer terminal, acquiring QR code information included in the QR code, and transmitting the acquired QR code information to the QR authentication server; a QR code authentication procedure of performing, by the QR authentication server, QR code authentication by comparing the QR code information received from the portable authentication terminal with QR code information generated for the user ID information, and transmitting results of QR code authentication to the legacy authentication server; and a service approval procedure of, when the results of the QR code authentication received from the QR authentication server indicate success of authentication, granting, by the legacy authentication server, final approval for the service. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
