摘要翻译：
本文证明了仅基于便携设备与WiFi接入点之间的连接日志，在保护用户隐私的前提下，准确识别特定的人类移动共享模式是可行的。我们从Polytechnology Montreal的Eduroam WiFi网络收集数据，省略了设备跟踪或物理层数据。我们选择检测的行为是与学术课程结束相关的运动，以及与课间小休息时间相关的模式。在我们的实验中，自我施加了严格的条件。数据是已知的有误差噪声，并易受信息丢失。没有采取任何对策来缓解这些问题。数据预处理包括用于按时间间隔聚合数据的基本统计信息。我们在识别类间和类末的中断行为模式时，分别获得了93.7%和83.3%的准确率（通过袋装树）。

英文摘要：
  This paper proves the concept that it is feasible to accurately recognize specific human mobility shared patterns, based solely on the connection logs between portable devices and WiFi Access Points (APs), while preserving user's privacy. We gathered data from the Eduroam WiFi network of Polytechnique Montreal, making omission of device tracking or physical layer data. The behaviors we chose to detect were the movements associated to the end of an academic class, and the patterns related to the small break periods between classes. Stringent conditions were self-imposed in our experiments. The data is known to have errors noise, and be susceptible to information loss. No countermeasures were adopted to mitigate any of these issues. Data pre-processing consists of basic statistics that were used in aggregating the data in time intervals. We obtained accuracy values of 93.7 % and 83.3 % (via Bagged Trees) when recognizing behaviour patterns of breaks between classes and end-of-classes, respectively.
