METHOD OF PROVIDING SERVICE BASED ON BIOMETRIC INFORMATION AND WEARABLE ELECTRONIC DEVICE

A device for measuring biometric information includes an impedance measurement circuit, a storage circuit, and a control circuit. The impedance measurement circuit receives an electrical signal from aplurality of electrodes when the plurality of electrodes are in contact with a body of a user and measures a bioelectrical impedance using the electrical signal. The storage circuit includes a security area configured to store the bioelectrical impedance, body information of the user, and biometric information of the user obtained from the bioelectrical impedance and the body information. The control circuit includes an authentication means configured to determine access authority to data stored in the security area using an authentication procedure, obtains the biometric information from thebioelectrical impedance and the body information, and manages the security area through the authentication procedure provided by the authentication means. 用于测量生物计量信息的设备包括阻抗测量电路、存储电路和控制电路。当多个电极与用户的身体接触并使用所述电信号测量生物电阻抗时，阻抗测量电路从多
