Abstract
A face authentication apparatus includes a face image acquisition unit, a collation unit, a time measurement unit, and a threshold change unit. The face image acquisition unit acquires a face image of an authentication target. The collation unit performs face authentication on the face image of the authentication target on the basis of a threshold. The time measurement unit measures the elapsed time from the time of starting operation of the face authentication apparatus. The threshold change unit restricts changing of the threshold to a value larger than a value determined depending on the measured elapsed time.
Claims19
A biometric authentication apparatus comprising:
- a memory containing program instructions;
- and
- a processor coupled to the memory, wherein the processor is configured to execute the program instructions to:
- acquire biological information of a person who passes through a gate apparatus;
- perform biometric authentication on the biological information on a basis of a threshold;
- measure elapsed time from a time of starting operation of the gate apparatus;
- and
- receive a request for changing the threshold from a user, and restrict changing of the threshold to a value larger than a value determined depending on the measured elapsed time.
A biometric authentication method comprising:
- acquiring, by a processor, biological information of a person who passes through a gate apparatus;
- performing, by the processor, biometric authentication on the biological information on a basis of a threshold;
- measuring, by the processor, elapsed time from a time of starting operation of the gate apparatus;
- receiving, by the processor, a request for changing the threshold from a user;
- and
- restricting, by the processor, changing of the threshold to a value larger than a value determined depending on the measured elapsed time.
A non-transitory computer-readable medium storing thereon a program comprising instructions for causing a computer to perform processing to:
- acquire biological information of a person who passes through a gate apparatus;
- perform biometric authentication on the biological information on a basis of a threshold;
- measure elapsed time from a time of starting operation of the gate apparatus;
- and
- receive a request for changing the threshold from a user, and restrict changing of the threshold to a value larger than a value determined depending on the measured elapsed time.
