An authentication apparatus updates a first execution information entry corresponding to a first identification information entry of an authentication target having undergone authentication processing, and transmits the first identification and execution information entries to a management apparatus. The management apparatus updates an execution information entry corresponding to the first identification information entry, and stores a first sequence information entry indicating a sequence number. The management apparatus transmits the first sequence and identification information entries to the authentication apparatus. The authentication apparatus then stores the first sequence information entry, and further acquires, from the management apparatus, second execution and sequence information entries corresponding to a second identification information entry identified by comparing the first sequence information entry against a different one received before the reception of the first sequence information entry and stores the acquired information in association with the second identification information entry.
