Аутентификация пользователя по электроэнцефалографическим сигналам при моргании
Аннотация
В статье представлены результаты исследования в области применения электроэнцефалографии (ЭЭГ) для аутентификации человека. Разработан и описан алгоритм ЭЭГ-аутентификации на основе морганий. Аутентификация проводится по одному морганию, что занимает 2–5 секунд. Для сбора данных используется электроэнцефалограф Muse. Предобработка данных включает вейвлет-преобразование и выделение морганий. В качестве признаков используются геометрические характеристики ЭЭГ. Распознавание ведется классификатором на основе Случайного леса (Random Forest). По результатам тестирования процент верной аутентификации составил 95 %. Имеется возможность фоновой аутентификации. Реализованная система может быть использована для аутентификации студентов при дистанционном образовании.
