Abstract
(EN)
The present invention provides a method, an apparatus, and a system for transmitting and receiving information by using a QR code. The method can receive a first QR code including second terminal identification information from a second terminal, transmit the second terminal identification information to a server, receive, from the server, encryption information of the second terminal on the basis of the second terminal identification information, generate first terminal encryption information by using encryption information of the second terminal to encrypt encryption information of a first terminal, transmit the first terminal encryption information to the second terminal, receive, from the second terminal, a second QR code that is generated on the basis of the first terminal encryption information and that includes information data, and obtain the information data by using decryption information of the first terminal to decrypt the second QR code.
