חוקרים באירופה פיתחו מערכת שיכולה לעקוב אחרי בני אדם גם דרך קירות

Surveillance and data collection technology can be hard to keep up with. Researchers in Europe have improved a technology that uses Wi-Fi signals to track people. NTD Sean Marshall catches us up on how it works and how people have already developed ways to stop it. Researchers affiliated with a university in Rome have created a security system called HuFi that uses Wi-Fi signal information to harvest unique human biometric signatures. Not exactly like a fingerprint, but something similar. It's kind of like a security camera that doesn't need to see you. It can see through walls and isn't affected by lighting conditions. Represents a very unique privacy concern. The technology isn't new, but works at a much higher proficiency than past models. Jared Navar, tech consultant and creator of Zillion, was on hand to explain how this technology works. Really, anytime you or I walk through, we've got our phone in our pockets, our phone is sending out little pings, little requests to the router and asking, whether it's a known Wi-Fi network or not, it's basically sending out little probe requests as we call them. It'll send those from every few seconds up to 30-ish seconds, depending on if your phone's idle or not. Instead of a camera seeing you, a Wi-Fi signal from your phone could be tracked instead. As you're wandering through the library, it's sending those probe requests back to the router, and then it can, in theory, create a rough spatial map, but it can track and monitor your movements throughout. That's where they say the scariest might come in, is they are tracking you through walls and throughout a facility. There are already countermeasures for this technology to give people back some privacy. The CEO of XSOC designed the Ambient Cloaking and Control Layer, ACCL, to solve this. He says it doesn't block RS signals, it cryptographically transforms them. XSOC makes the electromagnetic space itself a controlled and cloaked domain. This allows organizations to stop ambient surveillance before it starts, securing not just data, but the very conditions under which privacy and access are established. So with countries like China, where the CCP openly track its citizens' moves and thoughts, the HUFI research paper attempts to position itself using Wi-Fi as a method for preserving privacy, but not using camera recording.
