Wi-Fi Routers Can Identify People with Near-Perfect Accuracy, Scientists Find

ai-technology · 2026-06-02

Researchers in Germany have demonstrated that standard Wi-Fi routers can identify individuals with nearly 100% accuracy by analyzing how radio waves reflect off human bodies. The technology, similar to radar, uses AI to create unique profiles based on body interactions with wireless signals. Tests involving 197 participants showed striking results. Unlike cameras, Wi-Fi monitoring is invisible, raising severe privacy concerns. The findings were published in the ACM Digital Library. The team warns that ubiquitous Wi-Fi networks pose unknown privacy threats, urging policymakers to develop safeguards.
