Scientists in Germany have demonstrated a startling new form of surveillance: identifying people using nothing more than ordinary WiFi signals. By analyzing how radio waves bounce around a room, researchers can effectively “see” and recognize individuals — even if they are not carrying a device and even if their phone is turned off.
Advances in signal processing and computational power have made it possible to extract meaningful data from ambient radio waves with high precision.
This development introduces new capabilities for surveillance and security, fundamentally altering the existing privacy landscape and surveillance paradigms.
Individuals can now be identified and tracked without carrying any electronic devices, expanding the reach of passive surveillance into previously private spaces.
