Researchers at the Karlsruher Institute of Technology in Germany have developed a method that allows ordinary WiFi routers to identify individuals with nearly 100% accuracy, even without active devices. This technology raises significant privacy concerns, as it could enable covert surveillance in public spaces.
- 01The system can identify individuals using standard WiFi signals and artificial intelligence, even if they are not carrying a device.
- 02The technology transforms ordinary routers into potential surveillance tools, raising concerns about privacy violations.
- 03In tests with 197 participants, the system achieved nearly 100% accuracy in identifying individuals.
- 04The researchers emphasize the need for stronger privacy protections in light of this technology's implications.
- 05The findings will be presented at the ACM Conference on Computer and Communications Security in Taipei.

Researchers from the Karlsruher Institute of Technology (KIT) in Germany have unveiled a groundbreaking method that enables ordinary WiFi routers to identify individuals with near-perfect accuracy. This system leverages standard WiFi signals and artificial intelligence to track people, even if they are not actively using a device. Professor Thorsten Strufe explained that by analyzing how radio waves bounce around a room, researchers can create a detailed 'image' of the environment and the individuals within it. The technology poses significant privacy risks, as it could allow for covert surveillance in public spaces like cafes and airports without individuals' knowledge. In trials involving 197 participants, the system demonstrated nearly 100% accuracy in identifying individuals, regardless of their movements or the angle of observation. The researchers are calling for enhanced privacy protections to be integrated into the upcoming IEEE 802.11bf WiFi standard to mitigate potential abuses of this technology. Their findings will be presented at the ACM Conference on Computer and Communications Security in November 2025.
