Abstract

PriCal is an ambient calendar display that shows a user's schedule similar to a paper wall calendar. PriCal provides context-adaptive privacy to users by detecting present persons and adapting event visibility according to the user's privacy preferences. We present a detailed privacy impact assessment of our system, which provides insights on how to leverage context to enhance privacy without being intrusive. PriCal is based on a decentralized architecture and supports the detection of registered users as well as unknown persons. In a three-week deployment study with seven displays, ten participants used PriCal in their real work environment with their own digital calendars. Our results provide qualitative insights on the implications, acceptance, and utility of context-adaptive privacy in the context of a calendar display system, indicating that it is a viable approach to mitigate privacy implications in ubicomp applications.

PriCal:环境日历显示中的上下文自适应隐私

PriCal是一种环境日历显示器，它显示用户的日程安排，类似于纸质墙壁日历。PriCal通过检测在场人员和根据用户隐私偏好调整事件可见性，为用户提供上下文自适应隐私。我们对我们的系统进行了详细的隐私影响评估，它提供了如何利用上下文来增强隐私而不被侵入的见解。PriCal基于去中心化架构，支持检测注册用户和未知人员。在一项为期三周的部署研究中，10名参与者在他们的真实工作环境中使用PriCal和他们自己的数字日历。我们的研究结果对日历显示系统中上下文自适应隐私的含义、接受度和效用提供了定性的见解，表明这是减轻ubicomp应用程序中隐私影响的可行方法。
