To achieve both convenience and crime prevention in authentication of a user of a vehicle.SOLUTION: A vehicle theft determination device 1 includes a biological information acquisition part 10 for acquiring biological information of a user of a vehicle, a determination part 30 for determining that the user is the principal, when first biological information similarity between the acquired first biological information of the user and previously registered biological information is equal to or more than a first threshold, and a driving feature acquisition part 20 for acquiring the driving feature of the user driving the vehicle, wherein when the first biological information similarity is less than the first threshold, driving feature similarity between the driving feature acquired by the driving feature acquisition part and the previously registered driving feature is equal to or more than a predetermined value, the biological information acquisition part acquires second biological information of the user, and the determination part determines that the user is the principal, when second biological information similarity between the second biological information and the previously registered biological information is equal to or more than a second threshold smaller than the first threshold.SELECTED DRAWING: Figure 1
【課題】車両のユーザーの認証において利便性と防犯性を両立させる。【解決手段】車両盗難判定装置1は、車両のユーザーの生体情報を取得する生体情報取得部10と、取得された前記ユーザーの第1生体情報と予め登録された生体情報との第1生体情報類似度が第1閾値以上である場合に、前記ユーザーが本人であると判定する判定部30と、前記車両を運転する前記ユーザーの運転特徴を取得する運転特徴取得部20とを備え、前記第1生体情報類似度が前記第1閾値未満である場合に、前記運転特徴取得部により取得された運転特徴と予め登録された運転特徴との運転特徴類似度が所定値以上であれば、前記生体情報取得部が前記ユーザーの第2生体情報を取得し、前記判定部は、前記第2生体情報と前記予め登録された生体情報との第2生体情報類似度が、第1閾値よりも小さい第2閾値以上である場合に、ユーザーが本人であると判定する。【選択図】図1
