Consequently, the demand is growing for secure mobile authentication methods. Setting a password-based authentication is the most frequently used method to protect data from intruders. However, people tend to use passwords, which can be easily remembered, hence easy to crack. Therefore, additional mechanisms are needed to enhance the security of password based authentication. One such complementary method is to use the typing pattern of the user, known as keystroke dynamics. Keystroke dynamics is an active research topic and has been researched mainly on desktop computers. There are very few studies conducted on mobile phones, even fewer on smartphones with touchscreen.

The next section briefly presents the research field of keystroke dynamics, reviewing the research studies conducted on devices with touchscreens. Then we present the research methodology, including data collection and its evaluation through identification and verification measurements. The final section presents some conclusions and future directions. 2. Keystroke Dynamics
