From Trump campaign signs to Planned Parenthood bumper stickers, license plate readers around the US are creating searchable databases that reveal Americans’ political leanings and more.
I’m looking for some adversarial material - numbers and letters at various angles that I can stick to the left and right of my license plate. To a human it will be obvious which part is my license plate but it might be sufficient to confuse an ALPR algorithm.
The readers are smart enough to distinguish between them, so it won’t actually do what you want. You could try to flood the plate with IR and cover the plate with clear-to-human IR reflecting cover. Might work. Might not.
The readers are just cameras with a sim card and use a simple motion sensor to trigger the camera. All of the processing is server side.
Readers are not smart. They are trained on data with license plates, and I doubt their training had license plates with extra characters on both sides.
I am curious what just running it over with a yellow highlighter might do at night
Literally illegal
It varies by state and there are no laws that say it needs to be machine readable. It only needs to be human readable.
to modify the license plate itself. but it’s surroundings? why?
What do you think obscuring means?
Obsucuring means making it partially or entirely not visible.
Obfuscating, however…
