Abstract:
A client device (100) determines whether or not access is allowed, based on security levels that are set for an application program and data held in a server device (200), and performs authentication with the server device (200) based on a challenge code generated using packet data from the application program. The server device (200), when the challenge code is transmitted thereto, transmits a preset response code to the client device (100), and permits access by the client device (100) if the server device (200) receives a set response to the response code from the client device (100).
