To provide a communication fraud prevention system that can suppress a significant drop in user convenience when the battery level of a terminal is low and a communication fraud prevention method.SOLUTION: A monitoring unit 36 monitors the remaining battery level Vx of a terminal 2. A stop unit 37 stops an unauthorized communication detection function in advance when the remaining battery level Vx of the terminal 2 becomes less than a specified amount, and thereafter, causes the terminal 2 to operate a vehicle 1 through second authentication (in this example, wireless verification or immobilizer verification) in which the operation of the terminal 2 is imposed on a user instead of first authentication (smart verification in this example).SELECTED DRAWING: Figure 1
【課題】端末の電池残量低下時のユーザの著しい利便性低下を抑制可能にした通信不正成立防止システム及び通信不正成立防止方法を提供する。【解決手段】監視部36は、端末2の電池残量Vxを監視する。停止部37は、端末2の電池残量Vxが規定量未満となった場合に、不正通信検出機能を先行して停止させ、以降は第1認証(本例は、スマート照合)ではなく、認証の実施にあたって端末2の操作がユーザに課された第2認証(本例は、ワイヤレス照合やイモビライザー照合)を通じて、端末2による車両1の作動を実施させる。【選択図】図1
