The present invention relates to a personal authentication method which uses an electroencephalogram in a steady state measured at an electrode position for optimized electroencephalogram measurement. The method comprises the steps of: disposing an electrode for electroencephalogram measurement in at least one among anterial, fronto-central, central-parietal, parieto-occipital, and temporal lobes; measuring an electroencephalogram corresponding to an eye-opening state and an eye-closing state which are alternatively performed in accordance with a predetermined transition time in the state where the electrode for electroencephalogram measurement is disposed; filtering a predetermined frequency band after removing a common noise component with regard to the measured electroencephalogram; extracting electroencephalogram data by making the eye-opening state and the eye-closing state into one trial; estimating frequency power in accordance with the elapsed time by using the extracted electroencephalogram data but performing in response to a plurality of trials; and identifying an individual using the frequency power estimated in response to the plurality of trials. Accordingly, individuals can be effectively authenticated by using an electroencephalogram in a steady state measured an electrode position for optimized electroencephalogram measurement.
