PROBLEM TO BE SOLVED: To achieve the efficiency of synchronous processing of information related to the presence/absence of the execution of authentication processing between a plurality of authentication devices.SOLUTION: An authentication device 10 updates first authentication execution information corresponding to first identification information of an authentication object in which authentication processing has been executed, and transmits the first identification information and first authentication execution information to a management device 20. The management device 20 updates the authentication execution information corresponding to the first identification information, and stores first order information indicating an order in which the authentication execution information has been updated. Then, the management device 20 transmits the first order information and the first identification information to the authentication device 10. The authentication device 10 stores the first order information. Furthermore, the authentication device 10 acquires second authentication execution information associated with second identification information specified on the basis of the comparison result of the other order information received prior to the first order information with the first order information and second order information from the management device 20. Then, the authentication device 10 stores the acquired second authentication execution information and the second order information in association with the second identification information.SELECTED DRAWING: Figure 1 |
