Current software for user authentication relies on the user to directly initiate some interaction (i.e., active authentication). However, active authentication systems are not accessible to individuals across all age groups. Continuous authentication schemes transparently observe a user's natural multimodal behaviors to leverage all possible signals as input for authentication, and hence do not require explicit authentication interactions to be initiated by the user, and are thus a promising framework for authentication by individuals of different age groups. This project's novelties are 1) to advance understanding of how individuals of different age groups use and perceive existing authentication methods, especially concerning users' mental models and acceptance of monitoring for the purposes of continuous authentication, and 2) to collect and analyze a variety of user signals in multiple behavioral and physiological modalities for age-aware continuous authentication on personal computing devices. This research also informs the design of continuous authentication interactions in other contexts such as public spaces and other smart environments, in which continuous authentication might be useful. The research includes three phases. (1) Elicit the mental models multi-generational users have of what it means to authenticate to a system, if and when they expect the system to re-authenticate them to confirm their identity as they continue to interact, and if and how they expect to receive feedback of authentication attempts. (2) Produce a novel dataset of behavioral and physiological data, such as touch gestures, keystroke dynamics, heart-rate variability, and skin temperature, through a series of data collection sessions wherein individuals of different age groups will be recruited to complete a diverse set of tasks. (3) Develop fundamental knowledge of age-aware continuous authentication through the analysis of these data using state-of-the-art machine and deep learning techniques. This project broadens participation in computing by involving students underrepresented in STEM and through K-12 outreach.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

当前用于用户身份验证的软件依赖用户直接启动某些交互（即主动身份验证）。但是，所有年龄段的个人都无法访问主动的身份验证系统。连续身份验证方案透明地观察用户的自然多模式行为，以利用所有可能的信号作为身份验证的输入，因此不需要用户启动明确的身份验证相互作用，因此是由不同年龄段个人的个人身份验证的有希望的框架。该项目的新颖性是1）促进对不同年龄段的个人如何使用和感知现有的身份验证方法的理解，尤其是有关用户的心理模型以及以连续身份验证的目的接受监控，以及2））收集和分析在多种行为和生理模式中，以持续持续的身份验证个人计算机上的多种行为和生理模式。这项研究还为在其他情况下（例如公共空间和其他智能环境）的连续身份验证相互作用的设计提供了信息，其中连续身份验证可能很有用。该研究包括三个阶段。 （1）引起多代用户对系统的含义，以及他们期望系统重新认证以确认其身份时，他们是否继续互动，以及他们期望获得身份验证尝试的反馈。 （2）通过一系列数据收集会话，生成了一个新颖的行为和生理数据数据集，例如触摸手势，击键动力学，心率变异性和皮肤温度，其中将招募不同年龄段的个体以完成一系列任务。 （3）通过使用最先进的机器和深度学习技术对这些数据进行分析，可以发展出对年龄感知的连续身份验证的基本知识。该项目通过参与STEM的代表性不足和通过K-12宣传来扩大参与计算的参与。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的审查标准，被认为值得通过评估来获得支持。
