RELAY DEVICE, RELAY METHOD, RELAY PROGRAM, AND RECORDING MEDIUM

PROBLEM TO BE SOLVED: To provide an electronic data relay system for preventing electronic data from being erroneously transmitted. SOLUTION: When transmitting electronic data, a relay device 100 compares a unique ID corresponding to a user name of a transmission destination with a unique ID associated with a telephone number of the transmission destination to retrieve whether or not there are coincident unique IDs. Thus, the electronic data can be prevented from being erroneously transmitted. Further, by receiving permission to receive the electronic data from a receiving terminal 300, a recipient can select the permission/rejection of the electronic data every time of transmission/receipt of the electronic data. In addition, the relay device 100 receives the unique ID corresponding to the user name of the transmission destination from the receiving terminal 300 to prevent other users from browsing the electronic data.
