Abstract
According to at least one example embodiment 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.
Claims17
A biometrics authentication system comprising:
- at least one memory storing a computer program;
- and
- at least one processor configured to execute the computer program to:
- set a frequency of performing biometrics authentication performed on a user so as to be different between when the system is in a first operation state and when the system is in a second operation state, the system being accessed by the user;
- and
- perform biometrics authentication on the user at the set frequency based on the system being in the first operation state or in the second operation state;
- wherein the first operation state is a state of accepting a biometrics authentication result used for determining login permission of the user to the system, and the second operation state is a state of accepting a biometrics authentication result used for determining whether the user is present while the user is logged in to the system;
- and
- wherein the frequency in the first operation state is higher than the frequency in the second operation state and the required accuracy of the biometrics authentication in the first operation state is higher than the required accuracy of the biometrics authentication in the second operation state.
6 more elements
A biometrics authentication method comprising:
- setting a frequency of performing biometrics authentication performed on a user so as to be different between when the system is in a first operation state and when the system is in a second operation state, the system being accessed by the user;
- and
- performing biometrics authentication on the user at the set frequency based on the system being in the first operation state or in the second operation state;
- wherein the first operation state is a state of accepting a biometrics authentication result used for determining login permission of the user to the system, and the second operation state is a state of accepting a biometrics authentication result used for determining whether the user is present while the user is logged in to the system;
- and
- wherein the frequency in the first operation state is higher than the frequency in the second operation state and the required accuracy of the biometrics authentication in the first operation state is higher than the required accuracy of the biometrics authentication in the second operation state.
3 more elements
A non-transitory computer-readable storage medium in which a program is stored, the program causing a computer to execute:
- setting a frequency of performing biometrics authentication performed on a user so as to be different between when the system is in a first operation state and when the system is in a second operation state, the system being accessed by the user;
- and
- performing biometrics authentication on the user at the set frequency based on the system being in the first operation state or in the second operation state;
- wherein the first operation state is a state of accepting a biometrics authentication result used for determining login permission of the user to the system, and the second operation state is a state of accepting a biometrics authentication result used for determining whether the user is present while the user is logged in to the system;
- and
- wherein the frequency in the first operation state is set higher than the frequency in the second operation state and the required accuracy of the biometrics authentication in the first operation state is higher than the required accuracy of the biometrics authentication in the second operation state.
