The present invention relates to a user authentication method and system by recognizing inserted metal in a bio-signal measurement environment using a wearable sensor. More specifically, the user authentication method comprises the following steps of: (1) inserting micro-sized metal to below a skin of a user; (2) allowing a metal recognition unit to recognize the metal inserted in the step (1); (3) allowing a communications unit to transmit metal data recognized in the step (2); and (4) allowing an authentication unit to compare the metal data transmitted in the step (3) with pre-stored user data, and to authenticate the user. According to the user authentication method and system by recognizing inserted metal in a bio-signal measurement environment using a wearable sensor of the present invention, in the bio-signal measurement environment using a wearable sensor, it is capable of simply and conveniently authenticate a user by inserting micro-sized metal, in which a specific number is encoded, to below a skin of the user, allowing a sensor to recognize the metal, and authenticating the user through the number encoded in the metal. |
