User Verification Using Evoked EEG by Invisible Visual Stimulation

Person authentication using biometric information has recently become popular among researchers. User management based on biometrics is more reliable than that conventional methods. To secure private information, it necessary to build continuous authentication-based user systems. Brain waves are suitable modalities for authentication. This study brain evoked by invisible visual stimuli. Invisible stimulation considered over overcome the obstacles faced a when system. stimuli confirmed changing intensity of image and presenting high-speed stimulation. ensure invisibility, different intensities were tested, with an 5 % was be invisible. improve verification performance, wavelet transform introduced Fourier because extracts both time frequency from wave. The scalogram obtained used as individual feature synchronizing template test data. Furthermore, synchronization waveband split power distribution scalogram. A performance evaluation 20 subjects showed equal error rate 3.8 %.
