Abstract: A system that prevents accomplishment of unauthorized communication between a terminal and a communication peer is provided. The system includes a measurement unit and a process execution unit. The measurement unit is arranged on at least one of the terminal or the communication peer to obtain a measured value corresponding to a distance between the terminal and the communication peer. The process execution unit determines whether the measured value is appropriate and controls actuation for authentication of the terminal through wireless communication performed between the terminal and the communication peer based on the determination result. The measurement unit executes a process for obtaining the measured value in a time period during which the communication for the authentication is not performed.
