智能手表的基于点击的用户身份验证
Tap-based User Authentication for Smartwatches
摘要：
本文介绍了TapMeIn，这是一种用于智能手表的免眼双因素身份验证方法。它允许用户在触摸屏上的任何地方点击他们选择的令人难忘的旋律（点击密码）来解锁他们的手表。根据敲击密码以及敲击时的生理和行为特征来验证用户。41名参与者的初步实验结果表明，TapMeIn可以达到98.7%的准确率，假阳性率仅为0.98%。此外，TapMeIn在坐姿和行走等不同条件下都能保持其性能。在速度方面，TapMeIn的平均认证时间为2秒。使用系统可用性量表（SUS）工具进行的用户研究表明，TapMeIn具有很高的可用性得分。
英文摘要：
This paper presents TapMeIn, an eyes-free, two-factor authentication method for smartwatches. It allows users to tap a memorable melody (tap-password) of their choice anywhere on the touchscreen to unlock their watch. A user is verified based on the tap-password as well as her physiological and behavioral characteristics when tapping. Results from preliminary experiments with 41 participants show that TapMeIn could achieve an accuracy of 98.7% with a False Positive Rate of only 0.98%. In addition, TapMeIn retains its performance in different conditions such as sitting and walking. In terms of speed, TapMeIn has an average authentication time of 2 seconds. A user study with the System Usability Scale (SUS) tool suggests that TapMeIn has a high usability score.
