Like someone commented much earlier, you can still get scanned while parked unless you wired them to stay on, in which case you're dealing with car battery drain problems. I probably won't go that far with this project. Sign up to join this community. The best answers are voted up and rise to the top.

You might check if your local jurisdiction has rules against obscuring plates. If the system alerts cops that you're doing something like this, they might pull you over to find out why.

One of his concepts now sold out is a scarf that you can wear like a hijab to disguise yourself from overhead drones. Harvey makes his garments with silver-plated fabrics that can reflect thermal radiation. He believes that by , countries will be able to perform full surveillance on their population for just. Harvey is also the brains behind CV Dazzle, a project that looks at how fashion can be used as a form of camouflage against facial recognition tech. The name comes from a type of World War I naval camouflage called Dazzle.
That look utilized cubist-inspired designs to "break up the visual continuity of a battleship and conceal its orientation and size," Harvey wrote in a New York Times op-ed. CV Dazzle puts an avant-garde spin on things, with quirky and theatrical hairstyles and makeup that break up the continuity of a face—that is, it messes with the pattern of a face that an algorithm may be designed to look for while detecting people.
Usually, those algorithms are scanning for the spatial relationship between features. For example, in most cases your eyes are usually horizontally aligned.
You can block detection, then, by creating what Harvey calls an "anti-face. If you really wanted to, you could walk around with a photo taped to the front of your shirt to avoid facial recognition systems from recognizing you as a person, as compared to, say, a chair.
The researchers wanted to see if they could fool a human-recognizing tool called YoLo , so they created or edited various images, testing them against the artificial intelligence system until they found one that worked. The winning image: A photo of people holding colorful umbrellas. The team rotated it and added some noise to fool the system. As you can see in this video , when one person holds that umbrella image, the AI system doesn't detect them as a person, while another human right next to them is identified.
When they switch, and the other person holds the umbrella picture, the first person is then recognized as human. URME Surveillance is a company dedicated to shielding people from facial recognition technology. When users wear the prosthetic, cameras equipped with facial recognition software identify those people as Savaggio, rather than their true identities.
For the license plate covers, this is less of a concern. You can easily slip it over any license plate without having to worry about surface material and dimensions. Overall, when picking out the best license plate camera blockers and reflectors, consider the surface first. Your license plate can take quite a beating out in the real world. So aside from avoiding red light and speeding cameras, a license plate spray is also expected to withstand harsh elements.
With the license plate cover, it should be waterproof as well. This could also protect your license plate from debris when driving over rough terrain. For sprays, always get a fast-drying formula. A lot of the license plate sprays are easy to spray on but could take hours to dry. But other than drying quickly, you also want it to dry as a clear coating that is invisible to the naked eye.
For those who are not as keen to apply a spray themselves, the license plate blocker cover is a much easier option. License plate blockers are a cheap but efficient way to make your number plate invisible to traffic cameras. Since red-light cameras can be prone to errors , having blockers like sprays or license plate covers can save you the time and money it takes to fight a potential speeding ticket.
Yeah giving the cops an always-on pretext to pull you over is not my idea of better privacy. Another way to protest the database would be to fill it with junk and false-positives. The plate-scanners don't try to identify the actual vehicle, they just scan anything that looks like a plate, hundreds of times a second. A monitor or tablet in a house street-facing window could generate the display of hundreds of random plates a second.
It was a major bummer, so I wouldn't try it if you're planning on visiting my lovely Garden State. I doubt these work. Mythbusters did fairly extensive testing. Response by poster: Thanks, everyone. I decided to get them anyway.
