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.

      wouldn’t that make it worse? basically any signal can bounce off you, making yourself even easier to track.

        The tracking happens even with a big reflector/scatterer on your head, but as long as you dont wear it regularly, the system would have difficulty identifying you from wave propagation alone

        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?

    Let me know when I can selfhost LibreFi Security on my router and use it for myself. Sounds great for private home use.

    Reminds me of the Christian Bale batman movie where he could spy on everywhere from the bat cave. Seemed so far fetched it almost ruined the movie

    • It was very much not even far fetched at that point. 1984 wrote about the same kind of surveillance, and at that time it would have been pretty far fetched. It was published in 1949; the video camera was only 24 years old at that point.

    Neat. Good luck protecting yourself from this.

    On the other hand, I’m seriously considering opening an Etsy shop selling foil-lined clothes. I’m pretty good at sewing. What do you think?

      You’d need fabric with continuous metallic threads that form a complete mesh to actually block the 2.4/5GHz signals - most DIY foil approaches leave gaps that WiFi can still penetrate thru.

        I feel like you’re overthinking this. There are people who buy crystal-infused drinking cups to reset their personal feng shui. (Spoiler: it’s just glitter.)

      When anyone or anything says that their product works “up to x%” I always presume it doesn’t really work at all.
      Christ, 1% is included in that “up to 95.5%” vague bullshit statement.

        I believe the reason they had to say “up to” is because the “signatute” will vary day to day ever so slightly (natural weight fluctuation), and if you gain or lose weight it can change dramatically, so the AI would have to constantly consider that and adjust it’s records.

        Honestly, unpopular opinion, but as long as it isn’t very short wavelength RF and they allow for self-hosted/open-source alternatives, I do find it a bit more privacy respecting than cameras, of course they have to say they are using the technology in public places.

        It also has it’s ways of fooling it, instead of wearing a wig and a false nose, you could wear a carbon-infused silicone fat suit to change the way you interact with RF.

        I hate it when commercials say “up to 100%.” It’s literally a pointless metric; that could mean anything from 0% to 100%, inclusive.

    You know, this, and the using wifi to see through walls stuff to me just immediately seemed to fall into “don’t research this, it can only be used for evil”.

          Well they can identify you are the same person but not your identity… So it’s like a disenbodied fingerprint.

          I suppose they could potentially make some database and train an AI on it someday to match to actual identities, but usefulness would be pretty limited at only 95% accuracy. That’s a false reading 1/20 times, so I suspect it would fail bigly to accurately recognize people from large data sets.

      They know you are a person and they can call your a certain UUID, but there will be a hard time matching you to your name etc.

      Camera’s can do face recognition (if your face is even in the database) to know who you are.

      This only works until the point where they have your form in a database which they can check…

          Never said that it wasn’t easy, it’s just harder than with facial recognition. In theory you could do it correctly in a way that it isn’t indentifiable.

          Also this works in places where faces are protected
