Shoulder-surfing resistant PIN-entry method

Abstract

Aiming at the problem that the traditional PIN entry method is vulnerable to shoulder-surfing attack, a secure PIN entry method against shoulder-surfing attack was proposed. The method changes the traditional input interface on the mobile device and uses the vibration channel of the device as the auxiliary channel to transmit the hidden information to the user. The user simply selects items to input PIN. The analysis shows that the proposed method can effectively resist shoulder-surfing attack.
