So I had researched it a while ago and don’t recall having found anything effective and non-suspicious to protect from public camera mass survaillence in cities and the like. Is there anything that is a good option for that yet, and if so, could you point me toward it?

      In the past, individuals have cut down red light and speed cameras using power saws. Are you suggesting a laser would be easier to just burn the pixels of the camera? Wouldn’t that be dangerous for people around you?

        electronics and industrial supply places, you can rip it off a diode based laser cutter but they’re very chonk, if you’re handy, you’d get just the diodes, lens and then make your own PCB with powersupply. You need adjustable because the light has to be in focus at the distance between you and the camera or else it will be to diffuse to disable the sensor, both too short and too far. You don’t really need a galvo head in this case just mount the pcb on something that can randomnly vibrate the laser in a small radius at the effective distance. You won’t be able to hit the camera sensor steady, you need to paint over it randomnly, with the right focus it will work even on rare occasionnal hits since those sensor are very sensitive to laser light

          Just add adruino with a distance sensing laser to point it it first to have it adjust focal length of the dangerous laser.

            Yes that makes sense, the range finding sensor from an old cell phone should do nicely.
            You can 3d print a geared lens barrel for small M12 lens quite easily.
            Just map the values to real gear position and bingo’s your uncle !

    You need to own a few copies of face recog software, and practice with face restructuring latex makeup which gives you a new realistic face with a new bone structure.

    Change walking gate. Get shoes with small platforms to change height, learn to walk naturally on those.

    Change mannerisms.

    It’s doable, but a major pain to pull it off.

    Like imagine quickly applying the latex makeup, walking in front of your own identical face recognition camera at home, take everything off, rest, repeat, 10 times a day, 300 days a year, for 10 years. Until it is second nature. Now you can rely on this to do serious work.

    You have to create a new person, basically. Assuming you practiced well and tested everything against real software, you can now be a different person for some hours in a reliable way. Once your secondary identity is exposed you’ll need a new tertiary identity. Never do anythiny fishy as your base identity.

    The real solution is political, like everyone else has said. Because you won’t be able to fool the system casually without a massive effort and practice, practice, practice on your own property first, before you rely on this for real work in the wild.

      It depends on the surveillance coverage. If it’s widespread enough, they can track you between your departure and arrival locations. You’d also need two more disguises for both entering and exiting.

      And of course, if you have a cell phone on you that pings anything, the jig is up.

    There is no effective technical solution for political problems. If you find one, it will soon be outlawed or rendered ineffective (eg if you wear mask and sunglasses, prepare to be harassed by law enforcement). Lobbying to stop unconstrained surveillance is the only option.

    IR blocking sunglasses are the simplest and most practical solution.

    Facial recognition systems compare the distance ratios between your eyes and nose primarily. Hiding your eyes is very effective towards fucking that up. A mask alone is typically not enough.

        Got any further info about these more advanced methods?

        I haven’t seen anything beyond the feature distance models. I have seen the models that essentially recreate you entire anatomy in 3D, place it in a database, then use that profile to match to in the future–almost like a 3D match move artist would do for visual effects. Not sure if this is just a proof of concept though.

        I wouldn’t be surprised if the millimeter wave scanners at airports have been collecting 3D models of us for this database over the last decades.

            The question is whether they were using infrared to see through normal sunglasses. IR blocking sunglasses prevent “night vision” from seeing through the lenses. Under infared, you can see through normal dark sunglasses like they aren’t even there.

    Covid masks can be effective, and it’s not as suspicious as asymmetrical makeup or a reflective hoodie. But no, there’s no good way to avoid being photographed in public.

        Yeah, a high-res image giving the position of ears, eyes, and nose is damning.

        ears and eyes alone give you a shocking amount of identifyability. We’re getting real fucking close to the CSI levels of facial identification.

        I’ve never seen an explanation as to why the guy thought that the lemon juice would work. Did someone tell it to him that or did he come up with it himself.

        Younger me recalls (incorrectly) that they used lemon juice on the film in the first Star Wars movie, as a special effect to blur the base of the land speeder so it appeared to be hovering. They actually used vaseline, smeared on the lens, not the film, plus had mirrors under the vehicle too. I had told this lemon juice ‘fact’ to several people before someone finally corrected me.

        My memory was wrong and I wonder how I came to that conclusion. Maybe I watched a ‘behind the scenes’ show on how they did the special effects, and they said it wrong. Maybe it was a show that presented the use of lemon juice in some other tangentially related special effect and I mixed the two up. Maybe I had read an article about using lemon juice to distort picture film in the developing process.

        I wonder if that bank robber did the same mistake but with far worse consequences. The time frame of the robbers mistake was around the same time as my confusion as well.

          I’m thinking it’s a conflation with a basic “invisible ink” made with lemon juice.

          You write a message in lemon juice on paper; the juice dries clear, then you can heat the paper to darken the juice and make the message legible.

        Walk on the front of your foot, the process require you to intentionally concentrate on your gait which causes it to change

        Not that you can do it all of the time, but it is a way to defeat gait fingerprinting.

          Just as normal sunglasse don’t fool facial recognition systems, modern gait recognition systems can’t be defeated by “just altering how you walk”. You can read more about it on The Hitchhikers Guide to Online Anonymity. There is this research paper.

          They link a specific device which can fool some systems, but a bit easier (although more inefficient) is just wearing very loose clothes that cover the movement of your muscles.

      Yea, but there is a database of peoples faces matched to their names. There is not a database of their bone lengths to the names. That measurement would be done after you were already under suspicion.

      Yeah, no dice, the better sensors these days don’t have any problem with that. Check out Project Farms recent doorbell camera review. He actually walks up to the doorbell camera with a full on flashlight in the pitch black of night and they still have no problem.
