PURPOSE: To make the wiretapping of a line difficult and to enhance confidentiality by adoping different systems for a data transmitting system used when the connection between information processor and a terminal side is confirmed and for the data transmitting system used after connection confirmation.
CONSTITUTION: When a user communicates, the transmitting system for the connection is set at a terminal side line interface part 2. The same transmitting system is set at an information processor side line interface part 5 by an information processor 4. When the user inputs a signal for a connection procedure from the terminal, input data are inserted from the interface part 2 through a communication line 3 to an interface part 5. The information processor 4 checks the data from the interface part 5, confirms the justifiability of a connection request, sends the connection confirmation completing data to the terminal side, and then, sets the transmitting system of the said user registered in the interface part 5 beforehand. On the other hand, when the terminal side receives the connection confirmation completing data, the transmitting system registered into the interface part 2 is set, and thereafter, the data are exchanged.
