Abstract

PURPOSE:To achieve sure secret protection, by transmitting the 1st ID value for self-discrimination to a center device by each terminal and comparing the 2nd ID value returned from the center device and that of itself. CONSTITUTION:The 1st IDA, B- which identify terminals are assigned to terminals TM1, TM2 belonging to a system of one network, and at the same time, the 2nd IDa, b- having a given relation with the 1st IDs are assigned and stored in the ID register IDR. A center HOST stored a correspondence table TBL between the 1st and 2nd IDs. A dial pulse designating the center is transmitted from the terminals, the terminal and the center are connected by a public line PL and the 1st ID, e.g., A is transmitted from the terminal. The center indexes the TBL and returns the 2nd ID to the A to the terminal. The terminal collates the 2nd IDa stored in the IDR with the 2nd ID returned from the center, and when it confirms the coincidence, the correspondence is made possible and when noncoincidence, no correspondence is made.
