Description

Facial authentication-based QR authentication method and system {Method and System for QR Certification Based On Face Certification}

The present invention relates to a facial authentication-based QR authentication method and system, and more particularly, communicates with a service server such as a financial company to obtain a QR image from a user terminal, and allows a user to easily access an airport gate by means of the obtained QR image. It relates to a passable, facial authentication-based QR authentication method and system.

In general, types of codes include one-dimensional codes and two-dimensional codes.

The one-dimensional code is a method of including data in only one direction, and the two-dimensional code is a method of recording a larger amount of data than one-dimensional code by including data in both vertical and horizontal directions. While one-dimensional codes can express only alphabets, numbers, and limited characters as data, two-dimensional codes can express not only Korean and Chinese characters, but also pictures. In addition, two-dimensional codes are not comparable to one-dimensional codes in terms of data capacity, and show superior functions to one-dimensional codes in terms of printing and reading.

Currently, barcodes that are generally used are one-dimensional codes, and are capable of expressing only simple information. That is, the barcode expresses desired alphabets, numbers, special characters, etc. as data by arranging a combination of white bars and black bars of different thicknesses in a one-dimensional manner. Other one-dimensional codes include UPC (Universal Product Code), EAN (European Article Numbering), and code 39/93/128/11.

Representative examples of two-dimensional codes include PDF417 codes, QR codes, and Data Matrix.

Among them, the QR code is fast to decode and has a large capacity, high density, and error correction function compared to existing codes. For example, such a QR code is attached to a book cover or printed and distributed so that information about a book can be found, or printed on a plate of a conveyor belt sushi restaurant or easily found on the street. Therefore, QR codes can be used for information necessary for general life, such as business cards, phone numbers, text messages, and homepage URLs.

However, the QR code-based service according to the prior art is provided in a fragmentary form in which one content or information is provided in one QR code.

For example, if information about text or image is recorded in a QR code, then when recognizing such a QR code, the corresponding information is obtained through the QR code without interworking with the server. As another example, when 'URL' information is recorded in a QR code, when recognizing the code, it interworks with the server, that is, connects to a website that matches the URL information and obtains related content from the website.

As such, the conventional QR code-based service has a problem in that service expansion is limited because it is a fragmentary service providing method with one-to-one matching between content and code to be provided.

On the other hand, an attempt to replace an ID card using such a QR code is disclosed in Korean Patent Publication No. 10-2015-0079323. However, the technology of using such a QR code in consideration of user convenience when passing through a gate at an airport has not yet been disclosed.

The present invention obtains a QR image from a user terminal by communicating with a service server such as a financial company, and provides a facial authentication-based QR authentication method and system that allows a user to easily pass through an airport gate based on the acquired QR image for that purpose

In one embodiment of the present invention in order to solve the above problems, in the user terminal, facial information transmission step of transmitting the facial image or feature information of the facial image and user information to the service server; In the service server, a user verification step of verifying the corresponding user by comparing the received face image or feature information of the face image with previously registered face image or feature information of the face image; A QR image registration step of generating and registering a certified QR image including information on whether to authenticate and QR identification information in a service server; In the service server, a QR image transmission step of transmitting the authentication QR image generated in the QR image registration step to a user terminal; QR image display step of displaying the authentication QR image by the execution of the application in the user terminal; A recognition image transmission step of recognizing the authentication QR image and transmitting the recognized authentication QR image to a service server in a scanner device in the airport; A verification information generation step of generating verification information by comparing the authentication QR image recognized in the recognition image transmission step in the service server with the authentication QR image generated in the QR image generation step; And transmitting the verification information generated in the verification information generation step to the scanner device; provides an airport facial authentication method including a.
