To provide a risk determination device, a risk determination method, and a program capable of determining a risk.SOLUTION: A risk determination device is comprised of: a reception unit that receives a sensor data notification in which a terminal ID transmitted by each of a plurality of terminal devices, a sensor detection value, and time information and position information acquired from a sensor detection value are associated with each other; a storage unit for storing the plurality of sensor data notifications; an analysis unit that determines whether or not a received sensor detection value is an outlier on the basis of the sensor detection value included in the sensor data notification including the same terminal ID as the terminal ID included in the received sensor data notification among the plurality of stored sensor data notifications, and when the analysis unit determines that the received sensor detection value is the outlier, on the basis of the outlier, the analysis unit derives an abnormal behavior of a user of the terminal device; and a processing unit that determines a risk of the user of the terminal device on the basis of the time information included in the sensor data notification including the outlier, the position information, and the derived abnormal behavior when the abnormal behavior is derived.SELECTED DRAWING: Figure 2

    【課題】危険性を判定できる危険性判定装置、危険性判定方法、及びプログラムを提供すること。【解決手段】危険性判定装置は、複数の端末装置の各々が送信する端末IDとセンサ検出値とセンサ検出値を取得した時刻情報及び位置情報とを関連付けたセンサデータ通知を受け付ける受付部と、複数のセンサデータ通知を記憶する記憶部と、記憶している複数のセンサデータ通知のうち、受け付けたセンサデータ通知に含まれる端末IDと同じ端末IDを含むセンサデータ通知に含まれるセンサ検出値に基づいて、受け付けたセンサ検出値が外れ値であるか否かを判定し、外れ値であると判定した場合に外れ値に基づいて、端末装置のユーザの異常行動を導出する分析部と、異常行動を導出した場合に、外れ値を含むセンサデータ通知に含まれる時刻情報と、位置情報と、導出した異常行動とに基づいて、端末装置のユーザの危険性を判定する処理部とを備える。【選択図】図2
