击键动力学是一种经过充分研究的行为生物特征，基于人们在输入字符时与键盘或小键盘互动的方式和节奏。本文探讨了这种模式的潜力，但不适用于配备触摸屏的智能手机。提出的主要研究问题是，就打字模式而言，触摸是否能有效地建立用户的生物特征档案，以供未来进行身份验证。为了达到这一目标，我们在Android平台上实现了一个触摸系统，并在不同的方法下执行了不同的场景，以评估其在认证最终用户方面的有效性。除了传统击键系统中使用的典型分类特征外，我们还引入了两个新的分类特征，即速度和距离。从实验中，可以争辩说，触击动力学可以相当有竞争力，至少当与从击键评估研究中获得的类似结果相比是如此。据我们所知，这是这一新出现的行为特征第一次受到关注。版权所有(C)2014 John Wiley&Sons，Ltd.
Keystroke dynamics is a well-investigated behavioural biometric based on the way and rhythm in which someone interacts with a keyboard or keypad when typing characters. This paper explores the potential of this modality but for touchscreen-equipped smartphones. The main research question posed is whether touchstroking' can be effective in building the biometric profile of a user, in terms of typing pattern, for future authentication. To reach this goal, we implemented a touchstroke system in the Android platform and executed different scenarios under disparate methodologies to estimate its effectiveness in authenticating the end-user. Apart from typical classification features used in legacy keystroke systems, we introduce two novel ones, namely, speed and distance. From the experiments, it can be argued that touchstroke dynamics can be quite competitive, at least when compared to similar results obtained from keystroke evaluation studies. As far as we are aware of, this is the first time this newly arisen behavioural trait is put into focus. Copyright (c) 2014 John Wiley & Sons, Ltd.
