This project will seek ways to greatly simplify privacy policy creation for users. It is based on the premise that the use of contextual information from applications that help users to coordinate or communicate with others - such as their calendar, messaging contacts, and address books - can help in creating privacy policies for location-aware systems. In contrast to earlier work on privacy that focused on such location-independent applications as Web services, the focus in this project is primarily on privacy in location-aware systems where users carry devices that help determine their location. These include GPS-enabled cell phones, wireless PDAs, and laptops. This work will leverage a location-aware infrastructure called Whereabouts, which is deployed in the new Computer Science and Engineering building of the University of Michigan.This research integrates three key concepts to simplify privacy policy specifications: (1) Privacy meta-policies: These are high-level rules that help map a user's context information. For example, a rule may make the user's location available to meeting participants near the start time of a scheduled meeting. (2) Privacy circles: These structures help users share privacy meta-policies with other users. The research will evaluate the hypothesis that privacy meta-policies will be much easier to share than low-level policy preferences that are typically available in existing privacy systems for ubiquitous computing. (3) Privacy mirrors: These are tools to help users understand the impact of their privacy meta-policies. In particular, a user can use a privacy mirror to see how a set of meta-policies would have revealed their location to other users for past events or scheduled future events.The success of this work will help users coordinate and collaborate better with each other using location information, while safeguarding privacy. This is important, because location-aware computing infrastructures are starting to become widely available, but they have still not penetrated mainstream use. Better calendaring and coordination tools will also result from this research, and it will help push the frontiers on understanding how people can better manage their privacy in the context of location-aware systems.

该项目将寻求方法来大大简化用户的隐私政策创建。它基于这样的前提：使用来自应用程序的上下文信息（例如日历、消息联系人和地址簿）可以帮助用户与他人协调或通信，从而有助于为位置感知系统创建隐私策略。相对于早期的隐私工作，集中在这样的位置无关的应用程序，Web服务，在这个项目中的重点主要是在位置感知系统，用户携带的设备，帮助确定他们的位置的隐私。这些设备包括GPS手机、无线PDA和笔记本电脑。这项工作将利用位置感知的基础设施，被称为Whereboard，这是部署在新的计算机科学与工程建设的密歇根大学。这项研究集成了三个关键概念，以简化隐私政策规范：（1）隐私元政策：这些是高层次的规则，帮助映射用户的上下文信息。例如，规则可以使用户的位置在安排的会议的开始时间附近对会议参与者可用。(2)隐私圈：这些结构帮助用户与其他用户共享隐私元策略。这项研究将评估的假设，隐私元政策将更容易分享比低层次的政策偏好，通常是在现有的隐私系统无处不在的计算。(3)隐私镜像：这些工具可以帮助用户了解其隐私元策略的影响。特别是，用户可以使用隐私镜像来查看一组元策略如何向其他用户显示他们过去的事件或计划的未来事件的位置。这项工作的成功将有助于用户使用位置信息更好地相互协调和协作，同时保护隐私。这一点很重要，因为位置感知计算基础设施已开始广泛使用，但尚未渗透到主流使用中。这项研究还将产生更好的沟通和协调工具，它将有助于推动人们在位置感知系统的背景下如何更好地管理自己的隐私。
