Design and development of a location privacy-preserving Android application

Abstract

Imagine walking by a cosmetics store and having an advertisement pop up on your smartphone urging you to buy something right on spot. Imagine visiting a friend in a hospital and having a social network sharing your location without your knowledge. Within this work, an Android application was developed to protect your location privacy by detecting out-of-routine events and notifying you dependent on your privacy settings. No online connection or excessive data hoarding is required, it uses a stay location algorithm to determine whereabouts and an instantaneous entropy predictor to calculate an out-of-routine measurement.
