Abstract
A gate device includes an authentication request unit, first authentication unit, second authentication unit, and gate control unit. The authentication request unit requests server-based first biometric authentication for a first user in an authentication area and registers successful authentication data. The first authentication unit performs second biometric authentication using a second user's biometric information at a first position against registered data. The second authentication unit performs third biometric authentication using a third user's biometric information at a second position against registered data. Upon successful third authentication, the gate control unit permits gate passage. Upon successful second authentication, the first authentication unit notifies the second user of passage permission
