Protecting the private information in terminal devices from third parties is currently a major security concern. For tackling the objective, the person authentication by passwords has predominantly been used. However, since password configuration and unlock are cumbersome work, people sometimes do not configure password on their terminal devices. This paper presents a novel person authentication system that uses a pressure distribution sensor. The proposed system activates when the user holds a terminal device. Thus, users can easily configure password and unlock their terminal devices. Besides, the user's burden in our system is low because our system does not require any specific user's actions such as gripping a finger tightly. Moreover, the responsiveness of our system is high because our system completes the person authentication by one second holding. In evaluation experiments, the false rejection rate was 3% and the false acceptance rate was 6%. Moreover, we found that shape and the pressure value around index finger, middle finger, thenar eminence, and hypothenar eminence were important factor in the proposed person authentication system.
