The US has increasingly adopted a surveillance society since the early 2000s, marked by advanced technologies such as targeted algorithms and biometric identification. A significant development is the 'WhoFi' system, which tracks individuals through Wi-Fi by detecting unique biometric signatures. Researchers at Sapienza University of Rome claim it operates with high accuracy, identifying individuals based on internal body signals. While marketed as privacy-preserving, the potential invasion of personal privacy remains substantial, as WhoFi would complement existing surveillance technologies.
A team of researchers at the Sapienza University of Rome recently released a paper outlining a new system capable of detecting 'biometric signatures' through distortions in Wi-Fi signals.
Unlike optical systems that perceive only the outer surface of a person, Wi-Fi signals interact with internal structures, resulting in person-specific signal distortions that act as a unique signature.
