WhoFi: Wi-Fi-Based Biometric Identification Achieves 95.5% Accuracy

Researchers from La Sapienza University of Rome have developed WhoFi, a novel biometric identification system using Wi-Fi signals. By analyzing patterns in Wi-Fi Channel State Information (CSI), WhoFi can accurately re-identify individuals across different locations, unaffected by lighting conditions and able to penetrate obstacles. Achieving up to 95.5% accuracy on the NTU-Fi dataset, WhoFi demonstrates the potential of Wi-Fi signals as a robust and privacy-preserving biometric modality, though privacy concerns remain.
