Your body can be fingerprinted and tracked by 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 based on how their bodies interact with Wi-Fi signals. The system can achieve up to 95.5% accuracy in identifying and tracking people, even through walls and other physical objects, making it more effective than conventional camera-based identification methods. The implications of this technology are significant, as it could be used for various purposes, from targeted advertising to government surveillance. The article notes that while the current setup is a proof of concept and may not be suitable for forensic applications, the ubiquity of Wi-Fi in public and private spaces makes the technology a potential threat to privacy and personal freedom. The article highlights the need for greater awareness and discussion around the ethical and privacy implications of such emerging technologies, as they have the potential to significantly impact individuals' right to privacy and freedom of movement.
