Ordinary WiFi networks could quietly become powerful surveillance tools, allowing people to be identified without cameras, special sensors, or even carrying a connected device. Researchers showed that unencrypted signals routinely exchanged between WiFi devices and routers can be used to create radio-based images of people and recognize them within seconds. In tests involving 197 participants, the system identified individuals with nearly 100% accuracy, even from different angles and regardless of how they walked.
Hahahahahaha, the government wants us only using state approved routers probably to make sure we are all using the one that let them watch us have sex in weird monochrome sonar-vision. We live in a surveillance state more every day and research like this is giving the FBI a fucking hard-on.
