| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this study, we focus on the EEG as a biometrics that can be detected continuously with high confidentiality, and aim to realize the person verification using the evoked EEG when presented with an imperceptible vibration stimulus. In previous studies, the content rates of the power spectrum in theta (4–8 Hz), alpha (8–13 Hz), and beta (13–43 Hz) wavebands as individual feature were derived from the evoked EEG data generated by vibration stimulation, and the verification performance was evaluated by SVM. The results showed that the EER was 28.5%, but this was not a sufficient verification result. In this paper, for the purpose of improving the verification performance, the weighted (normalized) content rates are used as new features and the verification performance is evaluated. As a result, the EER is improved to 16.9%. The verification performance is futher improved by changing the feature bandwidth to (6–10 Hz), which contain many components of evoked EEG, and the EER is reduced to 16.1%. |
