Automatic speed limit cameras have a built-in OCR software to recognize license plate.
There is probably a match within a license plate database to identify the car owner in order to send him his fine to the right postal address…
A funny hacker has decided to launch attempt to hack and erase the database by replacing his license plate number by a SQL injection code.
No sure this will work, but the idea could raise other hacker attempts while recognition software are more and more used in combination with cameras…
Even if does work against cameras, if a cop car sees you with that you'll get pulled over somewhat rapidly and possibly charged for deliberatly obscuring your number plate (dependeding upon the jurisdiction). Dumb plan
10/10 for innovation though.
Wow. Just Wow!
