In step S330, the security authentication device using brain waves and images may generate an authentication failure result when the brain waves of the factor authenticator do not exist in the database.

In step S340, the security authentication device using the brain wave and image may compare whether the image matched to the brain wave of the factor authenticator is the same as the image specified by the user as the password when the brain wave of the factor authenticator exists in the database.

According to an embodiment of the present invention, when the brain wave of the factor authenticator exists in the database, the brain wave may be a brain wave matching the password image stored in the database. Therefore, it may be necessary to compare whether the brain wave matches the password image.

In step S350, the security authentication device using brain waves and images may determine whether the image matched with the brain waves of the factor authenticator is the same as the image designated by the user as a password.

In step S360, the security authentication device using brain waves and images may generate a successful authentication result when the image matched with the brain waves of the factor authenticator is the same as the image designated by the user as a password.

According to an embodiment of the present invention, when a person views an image of the image set, brain waves generated by a frequency matched to the image may be different for each person. Therefore, even if it is determined in step S360 that the same brain wave as the brain wave of the authentication factor is stored in the database, the image seen by the authentication factor may be different from the password image stored in the database.

In step S370, the security authentication device using brain waves and images may generate an authentication failure result when the image matched with the brain waves of the factor authenticator is not the same as the image designated by the user as a password.

According to an embodiment of the present invention, the presenting step may be performed at least once, and different image sets may be displayed each time. When different image sets are displayed a plurality of times, steps S100 to S300 may be repeated each time. Through this, it is possible to perform security authentication with improved reliability compared to the case of executing steps S100 to S300 once.
