Location-aware computing not only creates many new opportunities for location-based applications, but also opens doors for new vulnerabilities and significant privacy risks. Location privacy protection confronts two unique challenges. First, location privacy requires a careful tradeoff between the quality of service provided by the service provider and the desired location privacy of the user; and second, location privacy represents personal experience and is context sensitive. The ``one size fits all'' solution will not scale. This project designs and develops: 1) a secure and customizable architecture for privacy-aware location-based services, which offers a careful combination of policy-based location privacy mechanisms and location anonymization based privacy schemes; 2) a set of safeguards for secure publication, subscription, transmission, use and storage of location information; and 3) a suite of privacy protection techniques for reducing the risks of unauthorized disclosure of location information, while maintaining the performance and service quality of location-based applications. The resulting capabilities are expected to have a significant practical impact on a broad range of location-aware applications that demand location privacy protection, from location-based industrial monitoring, such as intelligent transportation tracking, to location-based entertainment and homeland security. The prototype implementation and experimental research of this project are used as a teaching tool for courses covering mobile and advanced Internet computing technology. The educational program also includes training students through hand-on research, course projects or special problem courses on location-privacy protection enabled information delivery and dissemination applications. The project results will be disseminated via the following Web site http://disl.cc.gatech.edu/LocationPrivacy/.

位置感知的计算不仅为基于位置的应用程序创造了许多新的机会，而且还为新的漏洞和明显的隐私风险打开了门。 位置隐私保护面临两个独特的挑战。 首先，位置隐私需要在服务提供商提供的服务质量与用户所需的位置隐私之间进行仔细的权衡；其次，位置隐私代表个人经验，对上下文敏感。 ``一个尺寸适合所有''解决方案不会扩展。 该项目设计和开发：1）针对基于隐私感知位置的服务的安全且可自定义的体系结构，该服务提供了基于策略的位置隐私机制和基于位置匿名的隐私计划的仔细组合； 2）一组安全出版，订阅，传输，使用和存储位置信息的保障措施； 3）一套隐私保护技术，用于降低未经授权披露位置信息的风险，同时保持基于位置的应用程序的性能和服务质量。预计最终的功能将对广泛的位置感知应用程序产生重大实际影响，这些应用程序需要位置隐私保护，从基于位置的工业监测（例如智能运输跟踪）到基于位置的娱乐和国土安全性。该项目的原型实施和实验研究用作涵盖移动和高级互联网计算技术的课程的教学工具。该教育计划还包括通过手工研究，课程项目或有关位置私人保护的信息传递和传播应用程序的特殊问题课程培训学生。项目结果将通过以下网站http://disl.cc.gatech.edu/locationprivacy/传播。
