SUMMARY OF INVENTION

Technical Problem

In a face authentication system as disclosed in Patent Literature 1, when multiple times of face authentication are repeated, it may be an objective to set a suitable criterion in order to sufficiently reduce an error such as erroneous acceptance of a wrong person, erroneous rejection of a correct person, or the like and ensure a sufficient authentication accuracy.

At least one example embodiment of the present invention has been made in view of the above objective and intends co provide a face authentication system, a face authentication method, and a storage medium that can set a criterion of face authentication in a more suitable manner.

Further, at least another example embodiment of the present invention intends to provide a biometrics authentication system, a biometrics authentication method, and a storage medium that can set the biometrics authentication accuracy in a more suitable manner.

Solution to Problem

According to one example aspect of the present invention, provided is a face authentication system including: a criterion setting unit that sets a criterion of face authentication performed on a user so as to be different in accordance with a state of an access target system accessed by the user; and a face authentication unit that performs face authentication of the user based on the criterion.

According to another example aspect of the present invention, provided is a face authentication method including: setting a criterion of face authentication performed on a user so as to be different in accordance with a state of an access target system accessed by the user; and performing face authentication of the user based on the criterion.

According to yet another example aspect of the present invention, provided is a storage medium in which a program is stored, and the program causes a computer to execute: setting a criterion of face authentication performed on a user so as to be different in accordance with a state of an access target system accessed by the user; and performing face authentication of the user based on the criterion.

According to yet another example aspect of the present invention, provided is a biometrics authentication system including: an accuracy setting unit that sets an accuracy of biometrics authentication performed on a user so as to be different in accordance with a state of an access target system accessed by the user; and a biometrics authentication unit that performs biometrics authentication of the user based on the accuracy.

According to yet another example aspect of the present invention, provided is a biometrics authentication method including: setting an accuracy of biometrics authentication performed on a user so as to be different in accordance with a state of an access target system accessed by the user; and performing biometrics authentication of the user based on the accuracy.

According to yet another example aspect of the present invention, provided is a storage medium in which a program is stored, and the program causes a computer to execute setting an accuracy of biometrics authentication performed on a user so as to be different in accordance with a state of an access target system accessed by the user; and performing biometrics authentication of the user based on the accuracy.

Advantageous Effects of Invention

According to at least one example embodiment of the present invention, a face authentication system, a face authentication method, and a storage medium that can set a criterion of face authentication in a more suitable manner can be provided.

Further, according to at least another example embodiment of the present invention, a biometrics authentication system, a biometrics authentication method, and a storage medium that can set the biometrics authentication accuracy in a more suitable manner can be provided.
