Abstract

PURPOSE:To transmit only once an information code and the contents of information from a center to plural terminals by registering an information name and a terminal number to be transferred from the terminals to the center and allowing the center to form a secret code from them to store the code in the terminals. CONSTITUTION:When the terminal number and the information name to be transferred are inputted from an input section 5 of a terminal 1, a control section 6 transmits them to an information center 4 via a transmission and receiving section 8. The center 4 forms the secret code from the information name and the terminal number and transmits the code and the terminal number to the terminal 1. When the number is coincident with the terminal number stored in a memory 9, the terminal 1 stores the secret code in a secret code memory 10. When requested information is generated, the center 4 transmits its information code and the information itself. When the number operated from the information code and the own terminal number is coincident with the secret code stored in the memory 10, the terminal outputs the contents of information to an output section 7. Then, the requested data is received by each terminal by transmitting the identical information to the plural terminals only once from the center.

Information center 4 receives the terminal number and information name, and
From the correspondence table in the figure, we know that the information code is "/156". Next, the terminal number ``1111'' and the information code ``456'' are subjected to arithmetic operations (for example, addition), and the terminal number 1 is found to be ``1567'', and the terminal number and the PIN code are transferred to the terminal 1.

Next, when requested information (for example, road information) is generated in the information center 4, the information code and the information itself are sent to the transmission line 3. The terminal receives the transferred information and performs arithmetic (addition in this example) on the information code ("456" in this example) and the terminal number ("1111" in this example), and the PIN code becomes "'1567". The information is compared with the information stored in the PIN code memory 10 (in this example, "1567"), and if they match, the information content is output from the output unit 7, and if they do not match, the information is discarded. do.

(Effects) As explained above, the present invention allows a terminal that requests information transfer to store a pin code obtained from the terminal number and information code from the center, and when the center transfers the information code and information, each terminal In this case, the information content is displayed only when the PIN code set from the center, the information code transferred with the information, and the PIN code obtained from the terminal number match, so the requested information is only sent to the terminal that requested the information transfer. It also has the advantage that the same information can be transferred to all terminals by sending the information code and information content to the transmission path only once, rather than having to transfer the same information from the center to each terminal that requested it. . Furthermore, this makes it possible to eliminate information leakage to terminals other than those registered with the center.
