Summary:
We have studied continuous personal authentication using evoked EEGs (Electroencephalograms) by invisible stimuli. Biometric authentication has attracted attention as a means for verifying individuals. In management of users of a system, it is necessary to authenticate them continuously because there is a risk that the users are spoofed by others. Therefore, we try to use EEG evoked by visual stimuli in continuous verification. However, given stimuli can be perceived prevent user's working. Thus, we attempt to use the evoked potential from stimulation that cannot be perceived (unnoticeable stimulation). The present analysis result shows that the power spectrum of the alpha-band (alpha-band power) which is caused by unnoticeable stimuli may tend to increase more than that caused by stimuli that people can perceive.
