That's not too hard to implement, and it seems to help. Paypal uses this
to help reduce fraud, and they saw something like a 90% decrease
after instituting this system. The tricky thing about what paypal
does is that they make their images rather nasty looking on purpose,
to make it harder to use OCR on them, but they are
still human-readable. I don't know what the algorithm for
making them look gunky is.
2 questions, what do blind users do, and what if you /want/ to bulk upload
samples?
