Abstract

The present disclosure provides a method performed by a user authentication apparatus for authenticating a user of an information processing device. The method includes: visually outputting a code image including predetermined information to allow the information processing device to capture the code image; determining whether an authentication request including the code image and authentication identification information is obtained from the information processing device; and performing a user authentication process based on the authentication identification information after the authentication request is obtained.

Claims

1. A method performed by a user authentication apparatus for authenticating a user of an information processing device, the method comprising:

visually outputting a code image including predetermined information to allow the information processing device to capture the code image;

determining whether an authentication request including the code image and authentication identification information is obtained from the information processing device; and

performing a user authentication process based on the authentication identification information after the authentication request is obtained.

2. The method of claim 1, wherein said determining whether the authentication request is obtained comprises:

determining that the authentication request is obtained when the authentication identification information includes a telephone number of the information processing device and the code image are received, and

wherein said performing the user authentication process comprises;

authenticating the user as an authorized user when the telephone number and the predetermined information extracted from the code image are already registered in the user authentication apparatus.

3. The method of claim 1, wherein said determining whether the authentication request is obtained comprises:

determining that the authentication request is obtained when the code image visually outputted by the information processing device is captured by a camera of the user authentication apparatus, and

wherein said performing the user authentication process comprises;

extracting a private key by decoding encoded information included in the code image; and

authenticating the user as an authorized user when the private key is already registered in the user authentication apparatus.

4. The method of claim 1, wherein said determining whether the authentication request is obtained comprises:

determining that the authentication request is obtained when the code image visually outputted by the information processing device is captured by a camera of the information processing device and biometric information of the user is inputted, and

wherein said performing the user authentication process comprises;

extracting a private key by decoding encoded information included in the code image and removing the predetermined information from the decoded information; and

authenticating the user as an authorized user when the private key is already registered and the biometric information matches biometric information previously stored in the user authentication apparatus.

5. The method of claim 4, further comprising visually outputting an updated code image including information about an updated private key to allow the information processing device to capture the updated code image when the user is authenticated as the authorized user.

6. A user authentication apparatus for authenticating a user of an information processing device, the apparatus comprising:

an image output unit configured to visually output a code image including predetermined information to allow an information processing device to capture the code image;

an authentication request recognition unit configured to determine whether an authentication request including the code image and authentication identification information is obtained from the information processing device; and

an authentication unit configured to perform a user authentication process based on the authentication identification information after the authentication request is obtained.

7. The device of claim 6, wherein the authentication request recognition unit is configured to determine that the authentication request is obtained when a telephone number of the information processing device and the code image are received, and

Wherein the authentication unit is configured to authenticate the user as an authorized user when the telephone number and the predetermined information extracted from the code image are already registered in the user authentication apparatus.

8. The device of claim 6, wherein the authentication request recognition unit is configured to determine that the authentication request is obtained when the code image visually outputted by the information processing device is captured by a camera of the user authentication apparatus, and

Wherein the authentication unit is configured to decode encoded information included in the code image to extract a private key and is configured to authenticate the user as an authorized user when the private key is already registered in the user authentication apparatus.

9. The device of claim 6, wherein the authentication request recognition unit is configured to determine that the authentication request is obtained when the code image visually outputted by the information processing device is captured by a camera of the information processing device and biometric information of the user is inputted, and

Wherein the authentication unit is configured to decode encoded information included in the code image and remove the predetermined information from decoded information to extract a private key, the authentication unit configured to authenticate the user as an authorized user when the private key is already registered and the biometric information matches biometric information previously stored in the user authentication apparatus.

10. The device of claim 9, wherein the image output unit is configured to visually output an updated code image including information about an updated private key to allow the information processing device to capture the updated code image when the user is authenticated as the authorized user.
