本文提出了 Glass Unlock，这是一种使用智能眼镜进行智能手机解锁的新颖概念，理论上可以安全地抵御涂抹攻击、肩窥攻击和摄像头攻击。通过引入额外的临时秘密，例如仅在私人近眼显示器上显示的数字布局，攻击者无法理解在几乎空白的手机屏幕上观察到的输入。我们报告了一项使用三种替代输入方法的用户研究，并将它们与当前最先进的系统进行比较。我们的研究结果表明，Glass Unlock 仅适度增加了身份验证时间，并且用户更喜欢输入时间最慢的输入方法，因为它避免了显示器之间的焦点切换。
This paper presents Glass Unlock, a novel concept using smart glasses for smartphone unlocking, which is theoretically secure against smudge attacks, shoulder-surfing, and camera attacks. By introducing an additional temporary secret like the layout of digits that is only shown on the private near-eye display, attackers cannot make sense of the observed input on the almost empty phone screen. We report a user study with three alternative input methods and compare them to current state-of-the-art systems. Our findings show that Glass Unlock only moderately increases authentication times and that users favor the input method yielding the slowest input times as it avoids focus switches between displays.
