<p>PROBLEM TO BE SOLVED: To solve the problem that, when delivering data between systems using an external storage medium, there is the risk of information leakage caused by lending a borrowed medium or the like.SOLUTION: A data delivery system includes two systems which are not connected with each other by a physical network, and an external storage medium management server connected to an access point of a wireless LAN, and uses an external storage medium for data delivery between the two systems. The access point includes an area covering a terminal connected to the two systems, and the external storage medium includes an access function to the wireless LAN, and is locked in the connection to the terminal. While using the wireless LAN, availability confirmation including a medium ID is transmitted to the external storage medium management server and when an available response including a medium password for unlocking is received from the external storage medium management server, the external storage medium is unlocked by using the medium password, such that access for the data delivery is received from the terminal.</p> |
