在具有电容式显示屏和QWERTZ布局的移动电话上通过生物识别击键身份验证来实现安全是一种新的方法。在12键布局的手机上击键已经显示了在这些设备上进行身份验证的可能性。但随着硬件的变化，出现了新的通用要求。本文重点研究了基于击键动力学的身份认证。因此，我们将介绍新实现的键盘布局，以显示12键布局和QWERTZ布局之间的差异。此外，我们还比较了移动电话的数字(PIN)和字母(密码)输入。为此，我们添加了使用电容式显示器进行击键身份验证的新功能。在了解故障率的基础上，讨论了不同虚拟键盘布局对击键动力学安全性的改善。我们的结果表明，即使有了新的硬件因素，通过击键动力学进行身份验证也是可能的。
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 hardwar e changes, new general requirements have been arisen. In this paper, we focus on the authentication with keystroke dynamics. Therefore, we are presenting new implemented keyboard layouts to show differences between a 12 -key layout and a QWERTZ -layout. In addition, we compare a numerical (PIN) and alphabetic (password) input for mobile phones. For this, we added new features for a keystroke authentication with a capacitive display. With the knowledge of the fault rates, we discuss the improvement of the se curity for keystroke dynamics with different virtual keyboard layouts. Our results show, even with new hardware factors, that an authentication via keystroke dynamics is possible.
