Biometric Authentication Through a Virtual Keyboard for Smartphones
Security through biometric keystroke authentication on mobile phones with a capacitive display and a QWERTZ-layout is a new approach. Keystroke on mobile phones with a 12-key layout has already shown the possibility for authentication on these devices. But with hardware changes, new general requirements have been arisen. In this paper, the authors focus on the authentication with keystroke dynamics. Therefore, they are presenting new implemented keyboard layouts to show differences between a 12-key layout and a QWERTZ-layout. In addition, they compare a numerical (PIN) and alphabetic (password) input for mobile phones. For this, they added new features for a keystroke authentication with a capacitive display.
