Apparatus and method for authenticating a combination code using a quick response code

An apparatus for authenticating a combination code, the apparatus comprising:

• a processor configured to generate a Quick Response (QR) code and an authentication code which are used for authenticating a user, when an authentication request is received;
• a transmitter configured to transmit the QR code to a Personal Computer (PC) of the user and transmit an authentication message including the authentication code to a device of the user;
• and
• a receiver configured to receive a combination code used for authenticating the user and generated by the device of the user,
• wherein the processor determines whether the combination code is generated by combining the QR code and the authentication code, outputs an authentication result according to a result of the determination, and controls transmission of the authentication result to an authentication request server, wherein the authentication code includes at least one of a letter and a number.

A method of generating a combination code in an apparatus, the method comprising:

• receiving an image frame including a Quick Response (QR) code used for authenticating a user of the apparatus and an authentication message including an authentication code used for authenticating the user of the apparatus;
• recognizing the QR code within the image frame and extracting the authentication code from the authentication message;
• generating a combination code by combining the QR code and the authentication code, wherein the combination code is used for authenticating the user of the apparatus;
• and
• transmitting the generated combination code to an authentication server, wherein the authentication code includes at least one of a letter and a number.
