Experts can now identify and track you using Wi-Fi signals that bounce off your body - and its over 95% accurate. A new surveillance method identifies and tracks you using Wi-Fi signals — without needing a phone, camera, or wearable. Developed by researchers at La Sapienza University of Rome, the system has been dubbed "WhoFi." Ir reads how Wi-Fi waves interact with a person’s body, essentially creating a unique biometric “fingerprint” based on the way wireless signals bounce off them. This allows a person to be identified and re-identified across rooms and even different locations, all without visible technology or consent. 🔦 Why swap cameras for radio waves Wi-Fi keeps working when lights are off, walls block sight, or crowds get in the way. A router sends a signal, the air, walls, bones, and backpacks bend that signal, and every body shape leaves its own tiny distortions. The paper grabs those distortions, known as Channel State Information, as a privacy-friendly fingerprint. Unlike previous attempts at similar tracking, which topped out at 75% accuracy, WhoFi leverages neural networks and standard, low-cost Wi-Fi routers to achieve unprecedented precision. The implications are enormous: this could revolutionize everything from retail analytics to law enforcement surveillance, raising pressing questions about privacy. The system works even through walls and in the dark, potentially making it more powerful than traditional camera systems. While still in the experimental stage, the technology’s reliance on widely available hardware suggests it could be deployed at scale sooner than most would expect.

مبادرة "نوابغ العرب" هدفها الأساسي هو تعزيز ثقة الإنسان العربي بإمكانياته، وقدراته، وتعريف الأجيال على قدوات ونماذج مشرّفة… واليوم لدينا نموذج مشرّف لشاب عربي.. نعلن اليوم عن الفائز بجائزة "نوابغ العرب" في مجال الهندسة والتكنولوجيا، وهو البروفيسور فاضل أديب من لبنان، أستاذ مشارك في معهد ماساتشوستس للتكنولوجيا (MIT) ، نشر أكثر من 80 ورقة بحثية وبراءة اختراع في مجالات الهندسة والتكنولوجيا، ولديه إسهامات بارزة في مجال الاستشعار اللاسلكي، ومنها أبحاثه وابتكاراته في مجال الاتصال اللاسلكي وخاصة في التعرف على الأجسام والذبذبات خلف الجدران، وتحت الأنقاض. كل التوفيق للبروفيسور فاضل أديب
