Your body can be fingerprinted and tracked using Wi-Fi signals
The article discusses a new technology called "WhoFi" developed by researchers at La Sapienza University of Rome, which can identify and track individuals using Wi-Fi signals. The system can "fingerprint" a person's body and track their movements in physical space, even through walls and other objects, with up to 95.5% accuracy. This technology has significant implications for surveillance and privacy, as it could be used to track people's locations and activities, including in private spaces. While the current system is still a proof of concept, the hardware required is relatively basic, and the accuracy is high enough to be concerning. The article notes that this technology could be used for both benign purposes, such as targeted advertising, and more sinister applications, such as government surveillance.
