摘要

传感器网络和位置跟踪技术的进步使许多基于位置的应用成为可能,但它们也带来了重大的隐私风险。本文介绍了我们在建筑内、环境发现应用、位置依赖医疗应用中安全增强室内位置跟踪系统的设计研究。安装在天花板上的信标散布在整个建筑物中,通过射频和超声波信号发布位置信息,并允许在移动和静态节点上运行的应用程序了解其物理位置。被跟踪对象携带侦听器节点,该节点在信标到达时侦听信标信息,并将这些信标信号转发给基站。侦听器使用与具有已知信标坐标的多个信标的距离计算其在坐标系统中的位置。本文主要研究位置感知传感器网络的隐私问题,因为位置信息对隐私特别敏感,并且可能足以揭示个体的身份。还描述两个使用我们已经实现的位置跟踪问题的普遍家庭医疗保健应用程序。

Security Enhanced Indoor Location Tracking System for Ubiquitous Home Healthcare
Advances in sensor networking and location tracking technology enable many location-based applications but they create significant privacy risks. This paper describes our study on design of security enhanced indoor location-tracking system for in-building, ambient discovery application, location-dependent healthcare applications. Ceiling-mounted beacons are spread throughout the building which publish location information on RF and ultrasonic signals and allows applications running on mobile and static nodes to learn their physical location. The object to be tracked carries listener node, this node listens the beacons information as they arrived and forwards these beacons signals to the base station. A listener computes its position within the coordinate system, using the distances from multiple beacons with known beacon coordinates. This paper concentrates on privacy problem location aware sensor networks, since location information is especially privacy sensitive and potentially specific enough to reveal the identity of individuals. Also describe two ubiquitous home healthcare applications that use the location-tracking problem which we have implemented.
