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

随着私有信息的日益增多，为了防止对移动设备的非法访问，移动身份验证是必要的。尽管在视力正常的人的移动身份验证方面取得了重大进展，但对视力障碍者的安全和可用的移动身份验证的探索在很大程度上仍然不足。该项目旨在为视障人士开发、原型化和评估新的安全和可用的移动身份验证技术。有三个研究重点。第一个重点是开发CurveAuth，它可以根据用户在设备屏幕上绘制的曲线对用户进行身份验证。第二个重点是开发TapAuth，它根据用户在设备屏幕上有节奏的手指点击或滑动的顺序来验证用户。第三个重点是开发ShakeAuth，它可以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。本研究还包括一个原型计划，并通过全面的用户实验来评估所提出的技术。所提出的技术的成功发展将对视障人士充分利用现代移动设备的力量来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应用程序的形式在网上公开。

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.
