- Scientists have developed a method using ordinary WiFi signals to identify people with near perfect accuracy, without needing specialized hardware.
- The technology analyzes beamforming feedback information (BFI) from WiFi routers, allowing AI to recognize individuals even if they are not carrying devices or their phones are off.
- In tests with 197 participants, the system achieved nearly 100% recognition accuracy, raising serious privacy concerns about covert surveillance in public and private spaces.
- Researchers warn that widespread WiFi networks could become invisible surveillance tools, potentially exploited by authorities or criminals without detection.
- The team is advocating for enhanced privacy protections in upcoming WiFi standards to mitigate risks, especially in authoritarian contexts.
