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 !

        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 mixed the two up

          How did that go? Was it useful for anything? It sounds like some old practical advice:

          Thoroughly mix 2 tablespoons of vaseline with 1 teaspoon of lemon juice and smear it on your penis just before sunset. That will keep the mosquitoes at a distance throughout the night.

          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.

    I asked Andi

    Recent advances in facial recognition technology have sparked development of various counter-surveillance clothing and accessories. These anti-surveillance methods fall into several key categories:

    Physical Alterations and Clothing

    • Patterned clothing with complex designs that confuse facial recognition algorithms[1]
    • Reflective materials that bounce back infrared light used by security cameras[1:1]
    • Special scarves and hoodies designed to break up facial features[1:2]
    • The “Camera Shy Hoodie” with embedded IR LEDs that overexpose security camera footage[2]
    • Cap_Able brand clothing with patterns designed to deceive recognition systems[3]

    Technical Solutions

    • Infrared LED glasses that blind facial recognition cameras while remaining invisible to human eyes[1:3]
    • Anti-surveillance devices that emit signals to interfere with camera sensors[1:4]
    • Reflectacles privacy eyewear that blocks IR cameras[4]

    Professional Applications

    • Small reflective dot stickers used for motion tracking and high-speed camera detection[5]
    • Camera obscura techniques used by photographers and artists[6]

    Law Enforcement Concerns

    • Police forces are expanding use of facial recognition vans and technology[7][8]
    • Civil liberties groups argue the technology shows racial bias and privacy concerns[9]
    • West Yorkshire’s Crime Commissioner states that facial recognition data “will not be stored”[7:1]

      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.

    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.

        Thing is, none of the suggestions in this thread would be used singularly against you. For instance, your gait, unless you genuinely are a member of The Ministry Of Silly Walks. LOL They will use these profiles as complimentary evidence. When all the cards line up, DING! you’re selected as a person of interest.

    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.

          I’d guess they probably just have a big blackbox ML image model now. A lot of computer vision tasks are being replaced by blackbox models.
