The Sapienza computer scientists say Wi-Fi signals offer superior surveillance potential compared to cameras because they’re not affected by light conditions, can penetrate walls and other obstacles, and they’re more privacy-preserving than visual images.
[…] The Rome-based researchers who proposed WhoFi claim their technique makes accurate matches on the public NTU-Fi dataset up to 95.5 percent of the time when the deep neural network uses the transformer encoding architecture.
Since it ‘figerprints’ you, changing your fingerprint by blocking parts of the signal with pieces of foil doesn’t seem like a terrible idea.
Now, the question is: is such a tactic like wearing gloves, or like using super glue?
