ABSTRACT:
It is necessary to authenticate each access by permitting or refusing it when a client makes an access to a server in a client-server system in which clients and servers are interconnected via a network. The client utilizes memory medium which stores both the server address and the memory medium's identification information. The client also uses a read-out device to fetch the contents of the memory medium and uses thus read out server address, to be connected to a desired server and then transmits the abovementioned read out identification information to ask for server access permission. The server, in response, when having received a server access permission request from the client, compares the memory medium identification information sent upon permission requesting to identification information stored beforehand and, based on the comparison results, sends the client the authentication of server access permission or refusal.
