Summary: | To enable authentication processing of a user terminal to be connected to a network even in the case that abnormality occurs in communication with a device for authentication.SOLUTION: A network system 1 has a second device 20 for authentication between a first device 10 for authentication and a user terminal 40. The second device 20 for authentication executes processing for receiving user information from the user terminal 40, and processing for communicating with the first device 10 for authentication to acquire a result of authentication success/failure based on the user information. Also, the second device 20 for authentication executes recording processing for recording authentication-succeeded user information in a second storage device 21, detection processing for detecting abnormality of communication with the first device 10 for authentication, and determination processing for collating the user information from the user terminal 40 with the user information stored in the second storage device 21 to determine authentication success/failure of the user terminal 40 in the case of detecting the abnormality of the communication.SELECTED DRAWING: Figure 1
【課題】認証用装置との通信に異常が発生した場合であっても、ネットワークに接続するユーザ端末の認証処理を可能にする。【解決手段】ネットワークシステム1は、第1の認証用装置10とユーザ端末40との間に第2の認証用装置20を有する。第2の認証用装置20は、ユーザ端末40からのユーザ情報を受信する処理と、第1の認証用装置10と通信してユーザ情報に基づく認証成否の結果を得る処理とを実行する。また、第2の認証用装置20は、認証成功済みのユーザ情報を第2の記憶装置21に記録する記録処理と、第1の認証用装置10との通信の異常を検知する検知処理と、通信の異常を検知している場合に、ユーザ端末40からのユーザ情報を第2の記憶装置21に記憶されているユーザ情報と照合して、ユーザ端末40の認証成否を判定する判定処理と、を実行する。【選択図】図1 |
