Study Shows Standard Wi‑Fi Routers Can Identify Individuals with Near‑Perfect Accuracy

Researchers reported that ordinary Wi‑Fi routers can identify individuals. The study found the identification accuracy to be near‑perfect. The capability relies on subtle signal variations captured by the routers. Experiments demonstrated reliable person recognition in typical home settings. Findings raise privacy concerns about everyday network devices. Experts suggest revisiting security protocols for consumer routers. The authors recommend further investigation into mitigation strategies. Regulators may consider new guidelines to protect user anonymity.
