Two-Factor Authentication System Using P300 Response to a Sequence of Human Photographs
提出一种双因素认证系统，结合用户对熟人照片的P300脑电反应（内在因素）和熟人知识（知识因素），实现接近零错误率的身份验证，优于其他基于脑信号的系统。
This paper proposes a two-factor authentication system that utilizes the knowledge factor: the knowledge of client's acquaintances as the key and inherence factor: P300 ERP responses to the visual stimuli as the medium. The system works by presenting a sequence of human photographs consisting of random people photographs mixed with a few of client's acquaintances photographs that trigger P300 responses. The system then verifies the client by considering the correctness of P300 responses to the client's acquaintances photographs. The proposed system achieves an error rate of nearly zero outperforming other brainsignal-based systems and has advantages over other conventional systems in the situations where the key is exposed to the imposer.
