WI-FI systems capable of identifying people and tracking them

11 August 2025

The way our bodies interact with the radio waves of WI-FI systems can create a signature of sorts, that’s as unique as a person’s fingerprint, and capable of identifying specific individuals. This according to Michael Crider, writing for PCWorld:

At present, the WhoFi system is a proof of concept requiring some incredibly advanced software to implement. But it’s very real, and the hardware used to develop it wasn’t anything special. According to the dataset in the paper, these results were achieved using the Wi-Fi signals generated by two TP-Link N750 routers, which are pretty basic models that aren’t even using the latest, fastest Wi-Fi tech.

Surveillance state, here we come.

Presently the “fingerprinting” technology developed by researchers in Italy at La Sapienza University of Rome, can identify a person with ninety-five percent accuracy. While the tool might be useful for police investigating crimes, there is obviously all manner of capacity for misuse and abuse.
