PROBLEM TO BE SOLVED: To protect a software by ending a terminal program when the ID of a terminal connected through a network to a center is equal. SOLUTION: When a program is activated at each terminal and connected to the center, the ID read out of a terminal ID memory 21 is sent out to the center by a communication part 22. This ID is stored in a terminal ID memory 13 for connection confirmation and compared with the ID read out of a connection use terminal ID memory 11 by a comparator part 14 and when they are equal, a terminal program ending command is read out of a command memory 15 through a control part 16 and sent out from a communication part 12 to the terminal so that the terminal program ends by a program activating part 23. When the ID is not coincident, a terminal program activation permitting command is read out of the command memory through the control part 16 and sent out to the terminal by the communication part 12 and the terminal program is activated by the program activating part. |
