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.

用于用户认证的当前软件依赖于用户直接发起某种交互（即，主动认证）。然而，并非所有年龄组的个人都可以使用主动身份验证系统。连续认证方案透明地观察用户的自然多模态行为，以利用所有可能的信号作为用于认证的输入，并且因此不需要由用户发起的显式认证交互，并且因此是用于由不同年龄组的个体进行认证的有希望的框架。该项目的创新之处在于：1）促进对不同年龄组的个人如何使用和感知现有身份验证方法的理解，特别是关于用户的心理模型和接受用于连续身份验证目的的监控，以及2）收集和分析多种行为和生理模式中的各种用户信号，用于个人计算设备上的年龄感知连续身份验证。这项研究还为其他环境中的连续身份验证交互设计提供了信息，例如公共空间和其他智能环境，在这些环境中，连续身份验证可能是有用的。研究分为三个阶段。(1)获取多代用户的心理模型，了解向系统进行身份验证意味着什么，他们是否以及何时期望系统在他们继续交互时重新验证他们以确认他们的身份，以及他们是否以及如何期望收到身份验证尝试的反馈。(2)通过一系列的数据收集会话，产生一个新的行为和生理数据的数据集，例如触摸手势，心率动态，心率变异性和皮肤温度，其中不同年龄组的个体将被招募来完成一组不同的任务。(3)通过使用最先进的机器和深度学习技术分析这些数据，发展年龄感知连续身份验证的基础知识。该项目通过让在STEM和K-12外展中未被充分代表的学生参与进来，扩大了对计算的参与。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
