摘要

本文介绍了一种新的安全问题，在这种安全问题中，个人的运动轨迹(就准确的路线而言)可以从一系列相互接触的记录和他们漫游的区域地图中推断出来。这种联系记录可以通过手机上的蓝牙通信获得。提出了一种在合理时间内解决跟踪推理问题的方法，并分析了推理算法的一些性质。

Automatic inference of movements from contact histories

This paper introduces a new security problem in which individuals movement traces (in terms of accurate routes) can be inferred from just a series of mutual contact records and the map of the area in which they roam around. Such contact records may be obtained through the bluetooth communication on mobile phones. We present an approach that solve the trace inference problem in reasonable time, and analyze some properties of the inference algorithm.
