With the boom of Augmented Reality (AR) and Virtual Reality (VR) applications, head-mounted smart wearable glass devices are becoming popular to help users access various services like E-mail freely. However, most existing password entry schemes on smart glasses rely on additional computers or mobile devices connected to smart glasses, which require users to switch between different systems and devices. This may greatly lower the practicability and usability of smart glasses. In this paper, we focus on this challenge and design three practical anti-eavesdropping password entry schemes on stand-alone smart glasses, named gTapper, gRotator and gTalker. The main idea is to break the correlation between the underlying password and the interaction observable to adversaries. In our IRB-approved user study, these schemes are found to be easy-to-use without additional hardware under various test conditions, where the participants can enter their passwords within moderate time, at high accuracy, and in various situations.

在头戴式智能可穿戴玻璃设备上设计防泄漏密码输入

随着增强现实（AR）和虚拟现实（VR）应用程序的兴起，头戴式智能可穿戴玻璃设备正变得越来越流行，可以帮助用户自由访问各种服务，例如电子邮件。但是，智能眼镜上大多数现有的密码输入方案都依赖于连接到智能眼镜的其他计算机或移动设备，这要求用户在不同的系统和设备之间进行切换。这可能会大大降低智能眼镜的实用性和可用性。在本文中，我们着眼于这一挑战，在独立智能眼镜上设计了三种实用的反窃听密码输入方案，分别名为gTapper，gRotator和gTalker。主要思想是打破底层密码和对手可观察到的交互之间的关联。在我们的IRB批准的用户研究中，
