Abstract

ABSTRACT Contact tracing is widely considered as an effective procedure in the fight against epidemic diseases. However, one of the challenges for technology based contact tracing is the high number of false positives, questioning its trust-worthiness and efficiency amongst the wider population for mass adoption. To this end, this paper proposes a novel, yet practical smartphone-based contact tracing approach, employing WiFi and acoustic sound for relative distance estimate, in addition to the air pressure and the magnetic field for ambient environment matching. We present a model combining six smartphone sensors, prioritising some of them when certain conditions are met. We empirically verified our approach in various realistic environments to demonstrate an achievement of up to 95% fewer false positives, and 62% more accurate than Bluetooth-only system. To the best of our knowledge, this paper was one of the first work to propose a combination of smartphone sensors for contact tracing.

使用智能手机传感器追踪流行病接触者

接触者追踪被广泛认为是抗击流行病的一种有效方法。然而，基于技术的接触者追踪面临的挑战之一是大量的假阳性，这质疑了其在更广泛人群中的信任价值和大规模采用的效率。为此，本文提出了一种新颖而实用的基于智能手机的接触追踪方法，除了使用气压和磁场进行环境匹配外，还使用WiFi和声学来估计相对距离。我们提出了一个结合了六个智能手机传感器的模型，当满足某些条件时，优先考虑其中一些传感器。我们在各种现实环境中实证验证了我们的方法，证明了与仅蓝牙系统相比，误报率降低了95%，准确率提高了62%。据我们所知，本文是最早提出用于接触追踪的智能手机传感器组合的工作之一。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
