Abstract： Most of the developed infectious-surveillance methods just realized the collection and analysis of the health and location data of residents in the affected area, and no any effective method was provided to implement the health monitoring, data privacy protection and treating for suspected patients, simultaneously. Therefore, a novel system model implementing the contacts′ health monitoring, location track recording and suspected handling was proposed in this work. Further, to implement the privacy protection of contacts′ personal information, a set of methods containing phone registration, identity authentication and encryption mechanisms were proposed, and to protect the users′ location information, we proposed the strategies of location data stored in a single database and encrypted by a double encryption mechanism. Theoretical security analysis demonstrated that the proposed remote monitoring system and privacy protection method can effectively defend the attacks in data transmission and privacy leakage in data usage. The research in this paper is expected to provide an effective way for the remote prevention and control of infectious diseases.

目前，基于传感器的网络监控技术已经应用于传染病领域，主要工作是监控患者的健康信息和位置信息。例如：文献、提出基于无线人体区域网络(Wireless Body Area Network，WBAN)和手机的方式，同时采集身体实时生命体征和动态社会互动信息的方法，从而对传染源进行动态追踪。文献利用WBAN采集体温血压等主要参数，实现了对埃博拉感染者的持续检测和远程监测。然而，上述工作只是实现健康数据和位置信息的采集和分析，并没有考虑被监测者的数据隐私问题。
