TL;DR
This paper introduces ALP, an adaptive framework for dynamically configuring location privacy protection mechanisms to improve privacy and utility in mobility data sharing, addressing user behavior variability over time.
Contribution
ALP is a novel framework that automatically tunes LPPMs in real-time or offline, enhancing privacy-utility trade-offs compared to static configurations.
Findings
ALP outperforms static configurations in privacy protection.
ALP improves data utility while maintaining privacy guarantees.
Experimental results validate ALP's effectiveness on real mobility datasets.
Abstract
With the increasing amount of mobility data being collected on a daily basis by location-based services (LBSs) comes a new range of threats for users, related to the over-sharing of their location information. To deal with this issue, several location privacy protection mechanisms (LPPMs) have been proposed in the past years. However, each of these mechanisms comes with different configuration parameters that have a direct impact both on the privacy guarantees offered to the users and on the resulting utility of the protected data. In this context, it can be difficult for non-expert system designers to choose the appropriate configuration to use. Moreover, these mechanisms are generally configured once for all, which results in the same configuration for every protected piece of information. However, not all users have the same behaviour, and even the behaviour of a single user is…
