Method and apparatus for authenticating user
First Claim
1. A method performed by a user authentication apparatus having a first camera for authenticating a user of an information processing device, an image output unit, an authentication request recognition unit and an authentication unit, the method comprising:
- visually outputting, by using the image output unit, a first code image including predetermined information to allow a second camera included in the information processing device to capture the first code image;
determining, by using the authentication request recognition unit, that an authentication request is obtained when a second code image visually outputted by the information processing device is captured by the first camera of the user authentication apparatus and biometric information of the user is obtained by the first camera of the user authentication apparatus;
extracting, by using the authentication unit, a private key by decoding encoded information included in the second code image and removing the predetermined information from the decoded information; and
authenticating, by using the authentication unit, the user as an authorized user when the private key is already registered in the user authentication apparatus and the biometric information matches biometric information previously stored in the user authentication apparatus;
visually outputting, by using the image output unit, a third code image including information about an updated private key to allow the information processing device to capture the third code image when the user is authenticated as the authorized user.

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.

2. A user authentication apparatus having a first camera for authenticating a user of an information processing device, the apparatus comprising:
-
an image output unit configured to visually output a first code image including predetermined information to allow a second camera included in an information processing device to capture the code image; an authentication request recognition unit configured to determine that an authentication request is obtained when a second code image visually outputted by the information processing device is captured by the first camera of the user authentication apparatus and biometric information of the user is obtained by the first camera of the user authentication apparatus; and an authentication unit configured to extract a private key by decoding encoded information included in the second code image and removing the predetermined information from the decoded information and configured to authenticate the user as an authorized user when the private key is already registered in the user authentication apparatus and the biometric information matches biometric information previously stored in the user authentication apparatus; visually outputting, by using the image output unit, a third code image including information about an updated private key to allow the information processing device to capture the third code image when the user is authenticated as the authorized user; wherein the image output unit is further configured to visually output an updated code image including information about a third private key to allow the information processing device to capture the third code image when the user is authenticated as the authorized user.
