This project investigates the feasibility of secure, robust, and usable gesture-based authentication as an alternative to traditional alphanumeric passwords and biometrics. It is motivated by the rapid increase in authentication-related security breaches and by the emergence of new human-computer interfaces. While the breaches have demonstrated the seriousness of the issue, two emerging types of gesture-based interfaces, multi-touch (smartphones, tablets) and camera-based (Kinect), offer a unique opportunity for robust solution.The benefit of gesture-based authentication over a purely-biometric one lies in the fact that it combines involuntary biometric features (e.g., hand shape), that are irrevocable, with user-controlled voluntary characteristics that can be easily changed. Three research thrusts are being pursued: 1) gesture recognition algorithms (search for robust gesture features, their compact representation, and reliable classification algorithms), 2) human factors (study of uniqueness, repeatability, ergonomics, device dependence of gestures, and gesture complexity) and 3) security considerations (evaluation of authentication performance under a range of performance measures and different threat models). A successful completion of this research will catalyze the development and adoption of next-generation authentication methods that are critically needed at the personal, institutional, and governmental levels. As the price paid (time, money, and resources) to repair a security breach can be astounding, this project will have substantial societal impact by increasing the sense of security and reducing breach-related costs. At educational level, this project is involved in middle and high school outreach at Boston University as well as the annual cybsersecurity competition CSAW at NYU-Poly.

该项目调查了安全，健壮且基于手势的身份验证的可行性，以替代传统的字母数字密码和生物识别技术。这是由于与身份验证相关的安全漏洞的迅速增加以及新的人类计算机界面的出现。 While the breaches have demonstrated the seriousness of the issue, two emerging types of gesture-based interfaces, multi-touch (smartphones, tablets) and camera-based (Kinect), offer a unique opportunity for robust solution.The benefit of gesture-based authentication over a purely-biometric one lies in the fact that it combines involuntary biometric features (e.g., hand shape), that are irrevocable, with user-controlled可以轻松更改的自愿特征。正在提出三个研究的推力：1）手势识别算法（搜索强大的手势特征，紧凑的表示和可靠的分类算法），2）人为因素（研究唯一性，可重复性，人工工程学，手势的设备依赖性以及手势复杂性和手势复杂性的设备依赖性和3）范围范围（评估范围均可表现的范围）。这项研究的成功完成将促进在个人，机构和政府层面至关重要的下一代身份验证方法的发展和采用。由于修复安全漏洞的价格（时间，金钱和资源）可能令人震惊，因此该项目将通过增加安全感并降低与违规相关的成本，从而产生重大的社会影响。在教育层面，该项目参与了波士顿大学的中学和高中外展，以及NYU-Poly的年度Cybsersecurity竞赛CSAW。
