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.
The reason the FCC is only allowing the sale of state approved routers in the US?
In tests involving 197 participants, the researchers said the system identified individuals with nearly 100% accuracy. The recognition remained effective regardless of viewing angle or how the participants walked.
I can totally believe when it tracks a person it can tell when the same person walks by again later. But matching people with their actual identities would require a database of wifi scan data that simply doesn’t exist yet.
