室内定位系统 (IPS) 可以在 GPS 不可用或不可靠的大型室内环境中启用许多基于位置的服务。移动众包作为构建 IPS 地图的有效方式被广泛提倡。本文首次对基于 WiFi 的众包 IPS 中的安全问题进行了系统研究，以促进设计和部署众包 IPS 时的安全考虑。我们识别了针对众包基于 WiFi 的 IPS 的三种攻击，并提出了相应的对策。攻击的功效以及我们的对策都在原型系统上进行了实验验证。这些攻击和对策可以轻松扩展到其他众包 IPS。
Indoor positioning systems (IPSes) can enable many location-based services in large indoor environments where GPS is not available or reliable. Mobile crowdsourcing is widely advocated as an effective way to construct IPS maps. This paper presents the first systematic study of security issues in crowd-sourced WiFi-based IPSes to promote security considerations in designing and deploying crowdsourced IPSes. We identify three attacks on crowdsourced WiFi-based IPSes and propose the corresponding countermeasures. The efficacy of the attacks and also our countermeasures are experimentally validated on a prototype system. The attacks and countermeasures can be easily extended to other crowdsourced IPSes.
