Abstract:
The daily use of smartphones along with third-party apps, which involve location data to be continuously collected, shared and used, have become a significant privacy concern. Besides, taking advantage of the rapid growth of wireless access points, the capability of these location-based services to track users’ lives, even sometimes with their consent, creates an urgent need for the development of more user-friendly and sociallyaccepted approaches to location privacy preservation. In this paper, we introduce a novel privacy-aware model for location-based apps to overcome the shortcomings related to user privacy during the location calculation process. By making the user device play a bigger role in the process, our model prevents users from relying on service providers’ trustworthiness. The model applies a cache-based technique to determine the position of client devices by means of wireless access points and achieve data minimisation in the current process. The model also establishe
s new personalised permission settings for the users while sharing their location information. We outline possible implementation of the proposal, and preliminary findings of the work-inprogress evaluation on the wireless data feasibility and usability that demonstrate deployment viability.
