PROTECT: The Hidden Information Leaking From Your WiFi Signals
WiFi security is more than passwords. Radio waves in your home can reveal movement, presence, and activity patterns. This guide explains WiFi sensing and how to protect yourself.
WiFi routers emit radio waves that bounce off people, furniture, and walls. With signal processing and machine learning, researchers can estimate presence, movement, breathing, and falls without cameras.
How to improve WiFi privacy
- Secure your router with WPA3 and strong passwords
- Audit connected devices regularly
- Update smart home hardware and firmware
- Limit unnecessary wireless devices
- Review smart product data policies
- Place routers away from public-facing windows
