Agentic AI-Powered Re-Identification: An Emerging, Scalable Threat to Mobility Microdata Privacy

arXiv:2606.27936v1 Announce Type: cross Abstract: The widespread collection of fine-grained location data by commercial data brokers creates a re-identification risk that is not widely recognised by the public. While prior research has established that mobility traces are highly unique and that individuals can, in principle, be identified from a handful of spatio-temporal points, such attacks have historically required significant manual effort from skilled analysts, limiting their practical scale. In this feasibility study, we demonstrate in a real world setting that agentic AI fundamentally
This study demonstrates a feasibility in the real world through agentic AI, turning a theoretical privacy risk into a practical, scalable threat with current technology.
The widespread collection of location data, previously considered a risk requiring significant human effort to exploit, can now be leveraged by AI, fundamentally altering privacy expectations and data security paradigms.
The barrier to re-identifying individuals from mobility microdata is significantly lowered, shifting the re-identification threat from a niche, labor-intensive activity to a scalable, automated one.
