According to recent studies, data generated from smartphone’s built-in accelerometer and gyroscope sensors can be used to infer users’ passwords. Currently, the secure keypad which is being used in smartphone apps is vulnerable to password attacks using sensor data. In this paper, we propose a secure keypad against password guessing attacks with accelerometer and gyroscope sensors. In the keypad, the rows of keys on the proposed keypad is randomly changed whenever a user inputs a letter of the password. Accordingly, it is very difficult to find out the user’ password using accelerometer and gyroscope sensor data. Moreover, the proposed keypad uses fake key buttons to further reduce the success rate of the attack. Users do not have to memorize fake keys. Users only need to touch the fake keys on the proposed keypad when they input their passwords. Because attackers cannot distinguish fake keys from touched keys, they cannot find out users’ passwords with accelerometer and gyroscope sensors. Therefore users can safely use a variety of internet services. |
