Abstract

Provided is a device supporting financial services, and an integrated system that incorporates technologies such as QR codes, blockchain, distributed finance (DeFi), non-fungible tokens (NFT), and metaverse into financial services. Furthermore, the present disclosure relates to a method and a device for providing blockchain-based financial services and, more particularly, to a method and a device for providing services of making a payment or exchanging money through blockchain-based cryptocurrency that is performed in real time without a delay in processing time. Further, the present invention relates to: an ATM device that determines forgery/falsification of an ID card in an account opening process and authenticates the identity of an ID card holder by comparing the face of the ID card holder with the face of a photo of the ID card; and an operating method therefor. Moreover, the present disclosure relates to an electronic access management system using QR codes.

Claims (48)

1 . An integrated system for providing virtual services that operates in a network environment, the system comprising:

a first terminal in which an online platform supporting a virtual service is executed; and

a server for operating the online platform,

wherein the server is configured to:

receive first user information associated with the first terminal;

receive a position information from a kiosk associated with the first terminal;

perform an authentication procedure on the first user of the first terminal based on the first user information, the authentication procedure comprising:

generating a first QR code based on the first user information and the position information,

transmitting the first QR code to the first terminal;

receive, from the kiosk, an access authentication request to access the virtual service on the first terminal based on the kiosk reading the first QR code from the first terminal;

generate a second QR code based on a current location of the first terminal;

transmit the second QR code to the kiosk and the first terminal;

receive, from the kiosk, a comparison result of comparing a first overlay QR code and a second overlay QR code, the first overlay QR code being generated by the kiosk and the second overlay QR code being generated by the first terminal;

transmit, to the first terminal, information for providing the virtual service on the first terminal, based on the comparison result.

2 . The integrated system of claim 1 , wherein the integrated system further comprises a second terminal in which the online platform is executed,

wherein the virtual service includes a DeFi (Decentralized Finance) service,

wherein the first terminal is configured to:

transmit the first user information to the second terminal;

receive blockchain-based encrypted information corresponding to the first user information from the second terminal; and

decrypt the blockchain-based encrypted information.

3 . The integrated system of claim 2 , wherein the kiosk comprises an input module and an output module.

4 . The integrated system of claim 3 , wherein the virtual service further includes a currency exchange service,

wherein the kiosk is configured to:

collect an identification (ID) card of the first user captured through the input module; and

analyze the identification card and determine whether to provide the currency exchange service, based on the analyzing result.

5 . The integrated system of claim 4 , wherein the kiosk is further configured to:

apply an object extraction algorithm to the ID card to obtain object information; and

determine whether to provide the currency exchange service, based on the object information.

6 . The integrated system of claim 5 ,

wherein the first terminal is configured to display the first QR code received from the server thereon,

wherein the kiosk is further configured to determine whether access of the first user to a place in which the kiosk is installed is permitted, based on the first QR code displayed on the first terminal.

7 . The integrated system of claim 6 , wherein the kiosk further comprises a scanner for collecting the identification card,

wherein the first user information comprises a mobile phone number of the first user and personal information of the first user.

8 . The integrated system of claim 7 , wherein the server is further configured to:

when an access authentication request signal is received from the kiosk, request current location of the user terminal to the first terminal; and

generate the second QR code based on the current location of the first terminal and a current standard time information;

wherein the first terminal is configured to:

generate the first overlay QR code based on the first QR code and the second QR code; and

transmit the first overlay QR code to the kiosk,

wherein the kiosk is configured to:

generate the second overlay QR code based on the first QR code and the second QR code; and

compare the first overlay QR code and the second overlay QR code with each other and determine whether access of the first user is permitted, based on the comparing result.

9 . The integrated system of claim 8 , wherein each of the first overlay QR code and the second overlay QR code is generated by positioning a position detection pattern of the first QR code and a position detection pattern of the second QR code on the same axis, and

wherein the kiosk is further configured to:

compare each cell of the first QR code and each cell of the second QR code with each other, and

set an identical cell thereof as a black cell and a non-identical cell thereof as a white cell.

10 . The integrated system of claim 9 , wherein the integrated system further comprises a plurality of kiosks respectively installed in a plurality of preset specific locations,

wherein the first terminal stores therein a plurality of first QR codes corresponding to the plurality of kiosks in a separate manner.
