A team from universities in Germany, Hong Kong, and the UK introduced a novel approach called Zero-Knowledge Location Privacy (ZKLP), aimed at offering privacy-preserving verification of location data. This technique allows users to demonstrate their presence in a specific area without disclosing their precise location, thereby maintaining privacy. Highlighted at the 2025 IEEE Symposium on Security and Privacy, ZKLP stands apart from existing methods by providing publicly verifiable, non-interactive proofs of geolocation, addressing privacy issues that arise from the growing demand for location data among data brokers.
With ZKLP, users can prove to any third party that they are within a specific geographical region while obfuscating their exact location for utility and privacy.
Location data, obtained from mobile phones and apps among other sources, has become highly sought after by data brokers. But it's particularly sensitive.
