Protecting location privacy from untrusted wireless service providers
Keen Sung, Brian Neil Levine, Mariya Zhivkova Zheleva · 2020
Access to mobile wireless networks has become critical for day-to-day life. However, it also inherently requires that a user's geographic location is continuously tracked by the service provider. It is challenging to maintain location privacy, especially from the provider itself. To do so, a user can switch through a series of identifiers, and even go offline between each one, though it sacrifices utility. This strategy can make it difficult for an adversary to perform location profiling and trajectory linking attacks that match observed behavior to a known user.
