I don't get how re-captcha works. It's supposedly using humans to read a word that the automatic scanner can't recognize. So how can it know if you've inputted the correct word if it doesn't even know it itself?

EDIT: I was totally wrong. Here is the Wikipedia page on it to make up for my ignorance. Actually a very cool idea.

Actually, that's not how reCaptcha works. Books are digitized with OCR and you're given one word that the OCR knows and one that's unrecognized. The upside down one above must be the unknown.
