Feasibility study on authentication based keystroke dynamic over touch-screen devices

Currently, people uses mobile devices as a part of their lives. This leads to the risk of data leaking or stealing. Due to the security issue, there are many studies try to increase security in these devices. The authentication process was bringing to the device with hope that it will prevent users from the security´s risk. Since the technology is developing fast, a new kind of risk comes to users without doubt. This study proposed a new study of feasibility to use keystroke dynamics on touch-screen devices. Using combination of four factors from keystroke dynamics, which are dwell time, interval time, interval timing ratio and distance between buttons, this study gives an accuracy at 82.18% with FAR and FRR at 0.020 and 0.178 respectively.
