<p>PROBLEM TO BE SOLVED: To provide a connection method capable of confirming a connection request source and connecting only a legal connection request source even when an illegal connection request source forges an IP address in a connection request and pretends to be the legal connection request source. SOLUTION: The most significant feature of this connection request source confirming and connecting method is that the connection request is abandoned after acquiring information contained in a connection request when the connection request is received and that an inquiry is performed from the side receiving the connection request to the side sending the connection request on the basis of the acquired information and information, which the connection request destination has, peculiar for the connection request source. As connection request information and the information peculiar for the connection request source, there are IP address, server name, identifier peculiar for an OS and route transmitting the connection request or the like. The difference between the conventional technology and this technology is that it is directly confirmed to the side sending the connection request whether or not the request is performed.</p> |
