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.

移动身份验证对于防止对具有越来越多隐私信息的移动设备进行未经授权的访问是必要的。尽管在视力障碍者的移动身份验证方面取得了重大进展，但针对视力障碍者的安全和可用的移动身份验证仍在很大程度上处于探索阶段。该项目是为视障人士开发、原型和评估新的安全和可用的移动身份验证技术。有三个研究推动力。第一个推力是开发CurveAuth，它根据用户在设备屏幕上绘制的手指曲线来验证用户身份。第二个推动力是开发TapAuth，它根据用户在设备屏幕上有节奏的手指轻击或滑动序列来验证用户身份。第三个推动力是开发ShakeAuth，它根据用户对设备的有节奏的摇动序列对用户进行身份验证。这项研究还包括一项通过全面的用户实验对所提出的技术进行原型和评估的计划。拟议技术的成功开发将对让视障人士充分利用现代移动设备的力量提高他们的生活质量产生深远的影响。项目成果将以演讲、出版物、数据集和Android/iOS应用程序的形式在网上公开发布。
