Development of a Typing Behaviour Recognition Mechanism on Android

Abstract

This paper proposes a biometric authentication system which use password based and behavioural traits (typing behaviours) authentication technology to establish user's identity on a mobile phone. The proposed system can work on the latest smart phone platform. It uses mobile devices to capture user's keystroke data and transmit it to web server. The authentication engine will establish if a user is genuine or fraudulent. In addition, a multiplier of the standard deviation "α" has been defined which aims to achieve the balance between security and usability. Experimental results indicate that the developed authentication system is highly reliable and very secure with an equal error rate is below 7.5%.
