You guys do realize that you only have to correctly type one of the two words, right?

So why even offer two words if you only need to have the one?

reCAPTCHA uses captchas for OCR. One of the words is known (usually the first) and used to confirm human-ness. The other is a non-OCR'd word that we help them OCR by typing it in.

OCR? .. I see a bad moon rising?

Why does it ask to type both words then?
 
He already explained. One word is known what to mean, which is used to establish you're a human, when you recognize it properly. The other word can't be OCR'd by a computer and uses your input (and others' for verification) to add to the database.

What Ice said....

When will people start reading more than the first four words? D: :p
 
I was trying it all last night, and not once did it accept only 1 word.
 
So apparently a lot of books are full of gibberish? More and more the mystery meat I see in recaptchas aren't even words, they're more like the sound you make when you get punched in the gut.
 
Also, I'm trying to follow the logic.... you are proving that you are not a computer and in the process helping computers learn to do the task that proves you're not a computer.

The point of a captcha is not to make it impossible for a computer, it's to keep scriptkiddies out. If you have Petabytes of data on OCR and a farm of server farms (ie your name is Google) you can recognize the characters in pretty much every captcha around.


On the topic of using a pair of words, one known and one unknown - you could at first use properly OCR'd words as "known" and slowly drift towards computer-unreadable words that you learned through earlier recaptchas. That way only the one with the recaptcha database can solve recaptchas.
