PROBLEM TO BE SOLVED: To provide a user authentication system and a user authentication method capable of ensuring a security relating to a loss of an electronic key.SOLUTION: A first biometric authentication unit 17 authenticates biometric information D input to an input unit 8 for an electronic key 3, and transitions the electronic key 3 to a first valid state when this biometric authentication is successful. A second biometric authentication unit 19 authenticates the biometric information D input to an input unit 12 of a vehicle 1, and transitions the electronic key 3 to a second valid state when this biometric authentication is successful. The electronic key 3 becomes communicable with the vehicle 1 through a key authentication when becoming the second valid state. When the key authentication between the vehicle 1 and the electronic key 3 is successful, the activation of an in-vehicle device 4 is permitted or executed.SELECTED DRAWING: Figure 1

    【課題】電子キーの紛失に対するセキュリティ性を確保することができるユーザ認証システム及びユーザ認証方法を提供する。【解決手段】第1生体認証部17は、電子キー3の入力部8に入力された生体情報Dを認証し、この生体認証が成立すれば、電子キー3を第1有効状態に遷移させる。第2生体認証部19は、車両1の入力部12に入力された生体情報Dを認証し、この生体認証が成立すれば、電子キー3を第2有効状態に遷移させる。電子キー3は、第2有効状態となると、車両1とのキー認証の通信が可能となる。車両1及び電子キー3の間のキー認証が成立すれば、車載装置4の作動が許可又は実行される。【選択図】図1
