Perhaps this could lead to a new kind of captcha that only bots can solve. I doubt it would be efficient, though.

If a correct answer is given, presume it's a bot.

Startup idea: create a CAPTCHA that humans recognize as one word, but OCR recognizes as a different word.

If this bot can generate scribbles from words. Theoretically, couldn't this bot work to teach an OCR-bot to effectively recognize scribbles as letters?

  Somebody just modded you down instead of answering... No. It couldn't be used to tech an OCR. Well, technically, it could, but all the OCR will learn is how to read text from this bot, not how to read text written by people.

  Nice, a captcha to block colorblind users!
  - arjie 12y ago
    That's a subset of the objective. The objective is to detect all humans because they wouldn't spot the 'face' in the coloured circles. Whether or not it's coloured doesn't change that. Unless you're concerned about the rights of colour-blind computers for some reason.

      Ha, oops, I guess I didn't read it closely enough. As someone who's partially colorblind, just seeing those dot patterns pisses me off... :P

  How do you know if the individual being tested doesn't see a face? You have to trust them when they say "no face here"... May as well just ask "are you human?"
- edwintorok 12y ago
  What if the computer just chooses a random rectangular region, or it always answers 'no face here'?
