Pseudo code of two-factor authentication for BYOD

Many solutions have been proposed to avoid stress and data leakage caused by BYOD (Bring Your Own Device) trend, including Mobile Device Management and authentication methods. In this paper, we will deal with the second solution more precisely the keystroke dynamics. The behavioral biometric of keystroke dynamics authenticates users by analyzing their ways of typing and generate for each system user a unique biometric reference. The method is simple to implement and inexpensive, it requires only a personal computer keyboard. At the end of the paper, we will propose an algorithm in three phases to implement keystroke dynamics. The main goal of this paper isn't to explain how the dynamic keystroke works but rather to improve the algorithm of implementation of this technique.
