    • An authentication system includes a mobile device carried by a user and a sensor sensing the user's biometric information. The mobile device includes a template storage unit storing the user's biometric information as a template, a first mutual authentication unit performing mutual authentication with the sensor via the user's body, and a template transmitter transmitting the stored template to the sensor via the user's body when the sensor is verified as valid. The sensor includes a second mutual authentication unit performing mutual authentication with the mobile device via the user's body, a sensing unit sensing the user's biometric information, a degree-of-match determining unit determining whether the biometric information matches the template, and a control-signal output unit outputting a preset control signal when the mobile device is verified as valid and when the biometric information and the template are determined to match each other.
    • 认证系统包括由用户携带的移动设备和感测用户的生物特征信息的传感器。 移动装置包括存储用户的生物体信息作为模板的模板存储单元,经由用户身体与传感器进行相互认证的第一相互认证单元,以及当存储的模板经由用户的身体传送到传感器时的模板发送器 传感器被验证为有效。 传感器包括经由用户身体与移动设备进行相互认证的第二相互验证单元,感测用户生物信息的感测单元,确定生物特征信息是否匹配模板的度数匹配确定单元, 信号输出单元,当移动设备被验证为有效时以及当生物特征信息和模板被确定为彼此匹配时,输出预设控制信号。
