摘要

这是MobiSys 14届会议论文集http://dx.doi.org/10.1145/2594368.2594375中完整论文的视频演示。该视频演示了在普通平板电脑上的几种身份验证形式，并将它们与我们基于手势的身份验证方法进行了比较。我们的方法通过估计重复手势的互信息来衡量用户生成的自由形式手势的安全性和可记忆性。我们展示了具有高互信息含量和低互信息含量的这类手势的例子。我们还展示了每个攻击者可以看到的信息，并描述了我们的系统如何抵抗这种攻击。

Video: User-generated free-form gestures for authentication: security and memorability

This is a video demonstration for a full paper available in MobiSys'14 proceedings http://dx.doi.org/10.1145/2594368.2594375. The video demonstrates several forms of authentication on a common tablet, and compares them to our method for gesture-based authentication. Our method measures the security and memorability of user generated free-form gestures by estimating the mutual information of repeated gestures. We show examples of such gestures with high and low mutual information content. We also show what information from each is visible to a shoulder surfing attacker, and describe how our system is resistant to such an attack.
