Abstract: A biometric authentication apparatus is provided. The biometric authentication apparatus includes one or more converters that convert a transmit signal of an electrical signal into a vibration signal of a mechanical signal and transmit the vibration signal vibrating within a set frequency range to a user, one or more sensor that receive a biometric signal corresponding to the vibration signal from the user and convert the biometric signal into a receive signal of an electrical signal, an authentication module that extracts anatomical feature information of the user from the receive signal and determines whether the user is a registered user based on the anatomical feature information, and a memory that stores a database for the registered user. The biometric signal is a frequency-based signal modified to include the anatomical feature information while the vibration signal passes through at least a portion of the body of the user.

Abstract: Provided is a personal authentication device based on an auditory brainstem response signal. The personal authentication device includes a signal generator, a signal acquirer, and a signal processor. The signal generator may output an auditory stimulus to an ear of a user, using a sound generator. The signal acquirer may acquire a first reference potential corresponding to a first interval, from a first electrode in close contact with the other ear of the user, and acquire a first evoked potential corresponding to the first interval from a second electrode in close contact with the ear, based on the first reference potential. The signal processor may generate a first auditory brainstem response signal, based on the first reference potential and the first evoked potential, generate authentication data for the user from the first auditory brainstem response signal, and compare the authentication data with registration data to authenticate the user.
