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.

I don’t disagree. The reader to which I was referring, is the entire system, to include the server-side processing. If it’s able to create a searchable db of political standings, we should assume it’s able to trim excess characters.

However, I’m not telling you what to do at all. I don’t know how they operate; I’m just making assumptions based on what they said and my knowledge of the processes used. Basically, just adding to the general knowledge pool, so someone smarter than I will have more data to make a more informed decision.

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

It varies by state and there are no laws that say it needs to be machine readable. It only needs to be human readable.
