TWC: Small: Collaborative: Secure and Usable Mobile Authentication for People with Visual Impairment

移动的认证对于防止对具有越来越多的私人信息的移动的设备的未授权访问是必要的。尽管针对视力正常人群的移动的身份验证取得了重大进展，但针对视力障碍人群的安全且可用的移动的身份验证在很大程度上仍未得到充分探索。这个项目是开发，原型和评估新的安全和可用的移动的身份验证技术的人与视觉障碍。有三个研究方向。第一个目标是开发CurveAuth，它根据用户在设备屏幕上的手指绘制曲线来认证用户。第二个目标是开发TapAuth，它根据用户在设备屏幕上有节奏的手指敲击或滑动序列来对用户进行身份验证。第三个目标是开发ShakeAuth，它根据用户对设备的有节奏的震动序列对用户进行身份验证。这项研究还包括一个计划，原型和评估所提出的技术，通过全面的用户实验。所提出的技术的成功开发将对视障人士充分利用现代移动的设备的力量以提高他们的生活质量产生深远的影响。项目成果将以讲座、出版物、数据集和Android/iOS应用程序的形式在线公开。

Mobile authentication is necessary for preventing unauthorized access to mobile devices with increasingly more private information. Despite significant progress in mobile authentication for sighted people, secure and usable mobile authentication for people with visual impairment remains largely under-explored. This project is to develop, prototype and evaluate novel secure and usable mobile authentication techniques for people with visual impairment. There are three research thrusts. The first thrust is to develop CurveAuth, which authenticates a user based on his/her finger-drawing curves on the device screen. The second thrust is to develop TapAuth, which authenticates a user based on his/her sequence of rhythmic finger taps or slides on the device screen. The third thrust is to develop ShakeAuth, which authenticates a user based on his/her sequence of rhythmic shakes of the device. This research also includes a plan to prototype and evaluates the proposed techniques through comprehensive user experiments. Successful development of the proposed techniques will have profound impact on allowing the visually impaired to fully embrace the power of modern mobile devices for improving their quality of life. Project outcomes will be made publicly available online in the forms of talks, publications, datasets, and Android/iOS apps.
