Ordinary WiFi can now identify people with near perfect accuracy
Scientists in Germany have demonstrated a startling new form of surveillance: identifying people using nothing more than ordinary WiFi signals. By analyzing how radio waves bounce around a room, researchers can effectively “see” and recognize individuals — even if they are not carrying a device and …
The article doesn't mention how this technology handles the challenge of people's WiFi signals being affected by walls, furniture, or other environmental factors that could throw off the accuracy claims. If the device can identify people through walls, why haven't we seen this technology used in public spaces like airports or stadiums for security purposes?
The article does acknowledge that environmental interference is a significant challenge, but it glosses over how the system's machine learning algorithms are supposed to compensate for these variables through pattern recognition and calibration. It's not just about the hardware limitations—it's about whether the privacy implications are being properly addressed when this technology can track people through walls.
The article doesn't mention how this technology handles the obvious privacy concerns of tracking people through their WiFi signatures, especially when the accuracy rate is described as "near perfect" - does this mean we're going to see law enforcement using this to identify people in public spaces without warrants or consent?
