Abstract or description

Emerging indoor positioning and WiFi infrastructure enable building apps with numerous Location-based Services (LBS) that represent critical threats to smartphone users' location privacy provoking continuous tracking, profiling and unauthorized identification. Currently, the app eco-system relies on permission-based access control, which is proven ineffective at controlling how third party apps and/or library developers use and share users' data. In this paper we present the design, deployment and evaluation of PL-Protector, a location privacy-enhancing middleware, which through a caching technique minimises the interaction and data collection from wireless access points, content distributors and location providers. PL-Protector also provides a new series of control settings and privacy rules over both, the information and control flows between sources and sinks, to prevent user information disclosure during LBS queries. We implement PL-Protector on Android 6, and conduct experiments with real apps from five different categories of location-based services such as instant messaging and navigation. Experiments demonstrate acceptable delay overheads (lower than 22 milliseconds) within practical limits; hence, our middleware is practical, secure and effcient for location-demanding apps.
