This has been posted and discussed many times since I've been on the list.
I have yet to see anyone suggest specifics on how to do it though.
It shouldn't be too hard to use JAI or ImageMagick or something similar
though to generate an image with text using a funky font then overlay
the image with another image to confuse OCR software...
I think you'd store the image text in a database, and pass some kind of
ID in the form as a hidden field, then on submission, look for that ID
in the database and compare the text in the database to what the user
typed in.
Again, it's all theoretical. Maybe someday, someone will write such a
tool and share with all of us how they did it.
