Researchers from Italy have introduced a groundbreaking method of identification dubbed "WhoFi," which leverages how the human body interacts with Wi-Fi signals. This innovative approach analyzes the unique way individuals block or alter Wi-Fi waves, enabling the system to recognize people across different locations with an impressive accuracy rate of 95.5%.
The technology works by capturing the subtle distortions in Wi-Fi signals caused by a person’s body shape, movement, and even posture. Unlike traditional biometric methods that rely on fingerprints or facial recognition, WhoFi requires no direct contact or visible imaging, making it a passive and versatile tool. The researchers highlight that this method surpasses conventional cameras, as it operates effectively regardless of lighting conditions, offering a robust solution for tracking in diverse environments—indoors or outdoors, day or night.

The study emphasizes the potential of Wi-Fi-based identification for enhanced security and surveillance. By using existing wireless infrastructure, the system could be integrated into smart homes, offices, or public spaces without additional hardware. However, the findings also raise privacy concerns, as the technology’s ability to monitor individuals unobtrusively could lead to widespread tracking if misused. As the research progresses, the balance between innovation and ethical considerations will be key to its future deployment.
