ANPR or Automatic Number Plate Recognition systems are
used
to enforce traffic regulations and catch felons. (I don't
advocate this, it's more of a thought experiment)
The idea is to design a custom wrap pattern for your car that
resembles many many standard registration plates enough to
overload
the ANPR algorithm. The algorithm would run out of time
trying
to find the actual registration plate amongst the many
decoys.
The pattern could not simply be other registration plates as
this
would break the law. But it could be lots of collections of
different sized numbers and phrases in various colours, or
even
shapes resembling numbers and letters.
A machine vision equivalent of chaff if you like.
This idea has been baking for some, but I was reminded of it
by
the recent story of the driver issued with a bus lane
contravention fine due to a woman with a T shirt sporting the
phrase KNITTER walking in it. His registration was KNIG TER
It may work in other countries too with careful design.
Over time the ANPR designers might modify their algorithms
to
detect the car shape, thus enabling them to concentrate
processing power in the actual number plate location. A
further
countermeasure would then be required to disguise the
outline
of your vehicle. A kind of automotive Ghillie suit. Which
maybe
be achieved by inserting polystyrene shapes under the wrap
before it is heat-shrunk on. Note: this may adversely affect
drive-ability and fuel economy.

I mean it would work fine right up until the machine learning
algos got hold of all of the recaptcha database of "all squares
with license plates. |
|
|
But more to the point the most likely immediate result would
be flagging as "deliberate avoidance" and the full image would
be passed over to a human for identification. |
|
|
The next stage is where the human exception- handler's
attention is caught by a message which seems to emerge from
all those letters. |

Wait; that gives me an idea ... |

I asked a Mountie friend what he wrote down when a car
was
missing plates. He said 'No Plate'. I asked what he would
write if I had a custom plate 'NOPLATE' and he was
flummoxed. I thought better of it and sure enough a few
years later I saw someone in the States had the same idea.
Every speeding fine or criminal inquiry within his state was
automatically sent to his address by the DMV computer
system
whenever the suspect vehicle had 'no plate'. |

Having said that, this is an interesting idea but a human
might be able to parse it where the ANPR system wouldn't. |
