摘要: Electrical brain activities can be measured noninvasively using electroencephalogram (EEG). This electric signal changes for different tasks, and also from subject to subject. Previous studies have shown that the EEG is unique enough used as a biometric characteristic. However, it well known activity change according our emotion or stress status, among many other factors. The stability of signals has not yet been explored understood. In this work, we explicitly investigated assessed permanence non-volitional brainwaves over course time. Specifically, analyzed how much period six months, since any drastic would make unusable an authentication method. results are very encouraging, yielding high accuracy throughout six-month period.
