项目摘要

A large and increasing number of services rely on data and measurements collected from mobile devices and shared with a centralized entity. Users enjoy these services (such as location-based services, recommendations, wireless connectivity and others) at the expense of sharing data from their mobile devices, which increases their privacy risk. For example, users may want to receive a location-based service, but they may be concerned about sending their exact location to a server or third parties. Recently, there has been increased awareness and concern about preserving user privacy, while still empowering the services that big data enable. While privacy has become a significant societal concern, the technical solutions in this domain are still lagging behind, and there is a gap between the theory of privacy and practices in the mobile ecosystem. This project will develop principled techniques for controlling the privacy-utility tradeoff for mobile data. Broader impact activities include collaborations with major players in the space of wireless networking and mobile data crowdsourcing, training students and broadening participation in computing.In this project, we focus specifically on data reported from mobile devices, including information about the wireless network, as well as personal/user data. Our goal is to develop privacy-preserving techniques to obfuscate reported data, while still providing guarantees for the quality of the provided service. We will develop both the theoretical framework (privacy-utility formulation, optimization of obfuscation techniques, and heuristic algorithms), as well as its application to wireless spectrum sharing, cellular signal maps, and personal information tracking. The project will produce models, algorithms, datasets, mobile system implementations and programming interfaces, which trade off utility vs. privacy in a principled and transparent way.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.

越来越多的服务依赖于从移动设备收集并与中央实体共享的数据和测量结果。用户享受这些服务(如基于位置的服务、推荐、无线连接等)的代价是从他们的移动设备共享数据，这增加了他们的隐私风险。例如，用户可能想要接收基于位置的服务，但他们可能担心将其确切位置发送给服务器或第三方。最近，人们对保护用户隐私的意识和担忧有所增加，同时仍为大数据支持的服务赋能。虽然隐私已经成为一个重大的社会问题，但该领域的技术解决方案仍然滞后，隐私理论与移动生态系统中的实践之间存在差距。该项目将开发原则性技术来控制移动数据的隐私和效用之间的权衡。更广泛的影响活动包括与无线网络和移动数据众包领域的主要参与者合作，培训学生和扩大对计算的参与。在此项目中，我们特别关注从移动设备报告的数据，包括有关无线网络的信息，以及个人/用户数据。我们的目标是开发隐私保护技术来混淆报告的数据，同时仍然为所提供的服务质量提供保证。我们将开发理论框架(隐私效用公式、混淆技术的优化和启发式算法)，以及它在无线频谱共享、蜂窝信号地图和个人信息跟踪中的应用。该项目将产生模型、算法、数据集、移动系统实现和编程接口，以有原则和透明的方式权衡效用和隐私。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
