Abstract
Disclosed is a user authentication method and apparatus. The user authentication method includes transmitting, to a user terminal, a visual authentication code that is recognized differently according to color vision deficiency, receiving, from the user terminal, a user input corresponding to the visual authentication code, and determining a user authentication result of a user based on a comparison result obtained by comparing the user input to a reference value determined based on pre-enrolled color vision information of the user.

A user authentication method based on color vision information, performed by a user authentication apparatus, the user authentication method comprising:
- transmitting, to a user terminal, a visual authentication code that is recognized differently according to color vision deficiency;
- receiving, from the user terminal, a user input corresponding to the visual authentication code;
- and
- determining a user authentication result of a user based on a comparison result obtained by comparing the user input to a reference value determined based on pre-enrolled color vision information of the user.
A user authentication apparatus for performing a user authentication method, the user authentication apparatus comprising:
- a memory and a processor,
- wherein the memory is configured to store instructions executable by the processor, and
- when the instructions are executed by the processor, the processor is configured to:
- transmit, to a user terminal, a visual authentication code that is recognized differently according to color vision deficiency,
- receive, from the user terminal, a user input corresponding to the visual authentication code, and
- determine a user authentication result of a user based on a comparison result obtained by comparing the user input to a reference value determined based on pre-enrolled color vision information of the user.
