## Abstract

An apparatus and a method are provided for authenticating a combination code using a Quick Response (QR) code. The apparatus includes a QR code receiver that receives an image frame including a QR code; a QR code recognizer that recognizes the QR code within the image frame; a combination code generator that generates a combination code including the QR code; and a combination code transmitter that transmits the combination code to an authentication server.

## Claims

### Claim 1

An apparatus for generating a combination code, the apparatus comprising:
a receiver configured to receive 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;
a processor configured to recognize the QR code within the image frame, extract the authentication code from the authentication message, and generate 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
a transmitter configured to transmit the generated combination code to an authentication server,
wherein the authentication code comprises at least one of a letter and a number.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the authentication message comprises a short-text message.

### Claim 3

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.

### Claim 4 (depends on 3)

The apparatus of claim 3, wherein the processor outputs an authentication success indicator as the authentication result, when the received combination code is generated by combining the QR code and the authentication code, and outputs an authentication failure indicator as the authentication result, when the received combination code is not generated by combining the QR code and the authentication code.

### Claim 5

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.

### Claim 6 (depends on 5)

The method of claim 5, wherein the authentication message includes a short-text message.

### Claim 7

A method of authenticating a combination code in an apparatus, the method comprising:
receiving an authentication request;
generating a Quick Response (QR) code and an authentication code which are used for authenticating a user;
transmitting the QR code to a Personal Computer (PC) of the user and transmitting an authentication message including the authentication code to a device of the user;
receiving a combination code used for authenticating the user and generated by the device of the user;
determining whether the received combination code is generated by combining the QR code and the authentication code;
outputting an authentication result according to a result of the determination; and
transmitting the authentication result to an authentication request server, wherein the authentication code includes at least one of a letter and a number.

### Claim 8 (depends on 7)

The method of claim 7, wherein outputting the authentication result comprises:
outputting an authentication success indicator as the authentication result, when the received combination code is generated by combining the QR code and the authentication code; and
outputting an authentication failure indicator as the authentication result, when the received combination code is not generated by combining the QR code and the authentication code.
