'This technology turns every router into a potential means for surveillance': Report claims Wi-Fi devices…
- Ordinary Wi-Fi networks can reportedly identify people without cameras or consent
- KASTEL researchers achieved nearly 100% identification accuracy across 197 volunteers tested
- Wi-Fi signals can reportedly reveal people from different viewing angles
A new study suggests that ordinary Wi-Fi networks could be repurposed to identify individuals without cameras, sensors, or their knowledge or consent.
Researchers from KASTEL, the Institute of Information Security and Dependability at KIT, tested the approach on 197 volunteers in controlled conditions.
Their system reportedly achieved nearly 100% identification accuracy regardless of a person's viewing angle or the way that person walked.
The technique relies on beamforming feedback information, a type of signal that connected devices routinely send back to a router.
This information is transmitted without any encryption, meaning anyone within range of the network could potentially intercept and read it.
By analyzing these radio signals over time, the system reportedly builds images of people from...
