- the authentication target person detection unit 202 detects a person (user) existing in the authentication area based on the detection signal from the area sensor 15. When the output of the area sensor 15 indicates that there is a user in the authentication area, the authentication target person detection unit 202 notifies the biometric information acquisition unit 203 to that effect.
- the biometric information acquisition unit 203 is a means for acquiring the biometric information of the person to be authenticated existing in the authentication area.
- the biometric information acquisition unit 203 acquires the notification relating to "there is a user in the authentication area" from the authentication target person detection unit 202, the biometric information acquisition unit 203 controls the camera 12 and images the user located in the authentication area.
- the biological information acquisition unit 203 attempts to extract a face image (face area) from the obtained image.

Specifically, the intruder determination unit 205 controls the camera 12 and acquires a face image in the same manner as the biometric information acquisition unit 203.
- the intruder determination unit 205 calculates the feature amount (feature amount of the intruder) from the obtained face image.
- the intruder determination unit 205 determines whether or not the calculated feature amount (feature amount of the intruder) and the feature amount acquired from the authentication request unit 204 substantially match. Specifically, the intruder determination unit 205 calculates the degree of similarity between the above two features. For the similarity, a chi-square distance, an Euclidean distance, or the like can be used. The farther the distance is, the lower the similarity is, and the shorter the distance is, the higher the similarity is. When the similarity is equal to or higher than a predetermined value, the intruder determination unit 205 determines that the two feature quantities are substantially the same (the intruder and the person to be authenticated are the same person).

In other words, the gate control unit 206 does not open the gate 17 in principle unless the above conditions (authentication success, the intruder and the person to be authenticated are the same person) are satisfied.
- the gate control unit 206 closes the gate 17 after a user who is permitted to pass by using a distance sensor or the like passes through the gate 17.

- the gate device 10 determines whether or not there is an intruder inside the own device (step S105). If the intruder cannot be detected even after a predetermined time has elapsed from the start of the intruder detection process (step S105, No branch), the gate device 10 executes the process according to step S109.
- step S105 determines whether or not the intruder and the person to be authenticated are the same person (step S106). If the intruder and the person to be authenticated are not the same person (step S106, No branch), the gate device 10 executes the process according to step S109.
- step S106 determines whether or not the authentication result acquired from the server device 20 is "authentication successful" (step S107). .. If the authentication result is "authentication failure", the gate device 10 executes the process according to step S109. Needless to say, the process according to step S107 may be executed before the process according to step S105.
- the gate device 10 opens the gate 17 (step S108).
