Boffins devise technique that lets users prove location without giving it away
Computer scientists from universities in Germany, Hong Kong, and the United Kingdom have proposed a way to provide verifiable claims about location data without surrendering privacy.
The technique, referred to as Zero-Knowledge Location Privacy (ZKLP), aims to provide access to unverified location data in a way that preserves privacy without sacrificing accuracy and utility for applications that might rely on such data. It’s described in a paper [PDF] presented this week at the 2025 IEEE Symposium on Security and Privacy.

If you’re online, you’re generating a constant stream of information about yourself — sometimes voluntarily, sometimes unwittingly — that is assembled and used to craft your online experience. And generate wealth for data brokers. Meanwhile, designers and managers of the digital infrastructure on which the world depends are engaged in a never-ending effort to thwart attempts, by both criminal enterprises and state actors, to exploit vulnerabilities in those systems.
