摘要：
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.
