Italian Researchers Develop Wi-Fi-Based Biometric Tracking Without Devices or Cameras

 

 

Researchers at La Sapienza University of Rome have unveiled WhoFi, a groundbreaking technology that uses Wi-Fi signals to track and identify individuals without the need for devices, cameras, or smartphones. Instead of relying on conventional surveillance methods, WhoFi creates a unique biometric fingerprint by analyzing how a person’s body distorts nearby Wi-Fi signals. This fingerprint allows for continuous re-identification as individuals move across spaces connected to different Wi-Fi networks.

This innovation opens new possibilities for security systems, smart homes, workplaces, and public surveillance, enabling real-time tracking without the visual limitations of traditional cameras. For instance, it could enhance emergency response systems, monitor unauthorized access in sensitive areas, or improve personalized experiences in smart environments like retail and healthcare facilities.

However, the development also raises serious privacy concerns. Non-invasive tracking methods like WhoFi could blur the line between convenience and intrusion, prompting discussions around data security, consent, and regulation. Experts warn that while this technology could transform biometric authentication and surveillance, it also poses risks if misused for covert monitoring or mass surveillance without oversight.

As WhoFi enters the spotlight, its potential to redefine wireless-based biometrics makes it a significant step in the evolution of non-intrusive tracking technologies. Moving forward, balancing innovation with privacy protections will be crucial for responsible deployment in public and private spaces.
