A 100 gigabyte drive can be purchased for about $100 and easily fits in a
coat pocket.
A relatively simple computer program could scan those 100,000 JPEG images in
a few hours for the identifying marks.
Now it becomes trivial for people to sell their votes and easy for an
unscrupulous vote buyer to determine if what the buyer paid for was actually
delivered. All it takes is an unethical worker at the County CLerk's office
to make an extra copy of the scanned images and then tuck the extra disk
drive in the worker's pocket for sale to a vote buyer.
Very, very scary.
