Is there a CPAN module that distorts an image to make it only human-readable?
You might be interested in how merlyn would have solved this problem back in 2001 if not jcwren would have hacked it a little bit later. ;-)
merlyn's example can relatively been broken easilly using for instance gocr (and a little image magick)
From a shell:
$ mogrify -negate <image.png>
$ gocr <image.png>
