Abstract
A system is provided including a first detection unit detecting a position of a first terminal, a second detection unit detecting a position of a second terminal, and a notification area determination unit determining a notification area based on the detected position of the second terminal, wherein, within the notification area, position information regarding the position of the first terminal is not notified. The system also includes a first route prediction unit predicting a route from a position of the first terminal to the notification area, a time calculation unit calculating a time period required for arriving at the notification area when the first terminal travels along the predicted route, and a notification unit permitting the notification when the first terminal does not arrive at the notification area after the time period elapses from the current time, and suppressing the notification while the time period does not elapse.
