Verifying a personas identity using brain responses to visual stimuli

Along with its clinical applications, EEG signals can be used in the biometric authentication domain based on its inimitable characteristics and uniqueness. Analyzed EEG signals are applied in many research studies as a communication trail between the human brain and the computer using BCI technology. In this paper, brain responses were triggered with visual stimulation of ten normal subjects. Biometric features were extracted from the energy of Gamma band EEG signals, and then classified using personal classifiers. The results showed that visual evoked potentials can be used as an authentication modality.
