Abstract
Ponència presentada a 10th International Conference on Localization and GNSS (ICL-GNSS), celebrada a Tampere (Finland) del 2 al 4 de juny de 2020This article presents a systematic review of privacy
in indoor positioning systems. The selected 41 articles on
location privacy preserving mechanisms employ non-inherently
private methods such as encryption, k-anonymity, and differential
privacy. The 15 identified mechanisms are categorized and
summarized by where they are processed: on device, during
transmission, or at a server. Trade-offs such as calculation
speed, granularity, or complexity in set-up are identified for
each mechanism. In 40% of the papers, some trade-offs are
minimized by combining several methods into a hybrid solution.
The combinations of mechanisms and their levels of offered
privacy are suggested based on a series of user mobility cases
