Guidance acquisition device, guidance acquisition method, and program
Face image data is acquired and a face image is captured, and a difference between a face image indicated by the face image data and the face image that is captured or a candidate of the difference is detected on the basis of at least one of the face image indicated by the face image data that is acquired, and the face image that is captured. Guidance is acquired on the basis of the difference or the candidate of the difference which is detected, and an output unit is controlled to output the guidance.
1. A face authentication system comprising:
a camera configured to capture face images of a target;
a reader configured to read out a face image from an identification document or an integrated circuit (IC) chip embedded within the identification document;
a memory storing instructions; and
a processor configured to execute the instructions to:
acquire a first captured face image of the target from the camera;
output, to a display, displayable guidance information on the basis of the first captured face image;
acquire a second captured face image of the target from the camera after the displayable guidance information is output;
perform face authentication by using the read out face image and the second captured face image; and
control a gate on the basis of a result of the face authentication.
2. The face authentication system according to claim 1 , wherein the identification document is a passport.
3. A face authentication method comprising:
reading out a face image from an identification document or an integrated circuit (IC) chip embedded within the identification document;
acquiring a first captured face image of a target from a camera;
outputting, to a display, displayable guidance information on the basis of the first captured face image;
acquiring a second captured face image of the target from the camera after the displayable guidance information is output;
performing face authentication by using the read out face image and the second captured face image; and
controlling a gate on the basis of a result of the face authentication.
4. A non-transitory computer-readable recording medium storing a program, which, when executed by a processor, causes the processor to:
read out a face image from an identification document or an integrated circuit (IC) chip embedded within the identification document;
acquire a first captured face image of a target from a camera;
output, to a display, displayable guidance information on the basis of the first captured face image;
acquire a second captured face image of the target from the camera after the displayable guidance information is output;
perform face authentication by using the read out face image and the second captured face image; and
control a gate on the basis of a result of the face authentication.
5. The face authentication system according to claim 1 , wherein the processor is further configured to execute further instructions that cause the processor to implement control for opening the gate and not to output guidance information for recapturing the second captured face image, in a case where the face authentication succeeds.
6. The face authentication system according to claim 1 , wherein the processor is further configured to execute further instructions to cause the processor to output the second captured face image to the display with the displayable guidance information.
7. The face authentication system according to claim 1 , wherein the displayable guidance information is information that guides the target to take off at least one of eyeglasses, a mask or a hat.
8. The face authentication system according to claim 1 , wherein the processor is further configured to execute further instructions to cause the processor to output information indicating that the target is being photographed.
9. The face authentication system according to claim 1 , wherein the displayable guidance information indicates that the result of the face authentication cannot be obtained, in a case where the result of the face authentication cannot be obtained.
10. The face authentication system according to claim 1 , wherein the displayable guidance information indicates that an error occurred in the face authentication, in a case where an error occurs in the face authentication.
