• reCAPCHA Experiment

Did you know: reCAPCHA only checks if you typed one word that it knows is correct. The other word is unreadable even by reCAPCHA computers itself, so it doesn't know if you typed it correct or not, and will say you were correct even if its wrong. Try this at home, kids!

:psyduck: informative
I have known this for a long time. Basically reCAPCHA gives you two words : one of them known to the service, the other not. The one that is not known has been taken from some OCD process to digitalize stuff like books. The known one is to confirm that you actually are able to read the text from the image correctly. If you enter the known word correctly it assumes that you entered the unknown one corretly as well.

Now I feel like an ass for not helping digitize books. :saddowns:
It says "Stop Spam, Read Books." I assume they pool everything together, find what the average population said, and go with that version.
[QUOTE=nicatronTg;27053002]It says "Stop Spam, Read Books." I assume they pool everything together, find what the average population said, and go with that version.[/QUOTE] If the word has tons of differing responses they probably get someone to take a look at it to see what's up.
I'm kind of surprised that someone would go to lengths to test this, it says it right on their website: [url]http://www.google.com/recaptcha/learnmore[/url] [quote]But if a computer can't read such a CAPTCHA, how does the system know the correct answer to the puzzle? Here's how: Each new word that cannot be read correctly by OCR is given to a user in conjunction with another word for which the answer is already known. The user is then asked to read both words. If they solve the one for which the answer is known, the system assumes their answer is correct for the new one. The system then gives the new image to a number of other people to determine, with higher confidence, whether the original answer was correct.[/quote]
I've been doing this since forever. I just type one word correct then hfioewhfiewfiouwehfiewh or something for the second one
so basically when I use reCaptcha, I'm writing books? cool!
I usually replace the second word with obscenities
Didn't /b/ have a thing going with this to try and get racial slurs put in the books?

That's the one
[QUOTE=ButtsexV2;27055244]I usually replace the second word with obscenities[/QUOTE] Brilliant. I'm definitely doing this now.
[QUOTE=CjienX;27065675]Didn't /b/ have a thing going with this to try and get racial slurs put in the books?[/QUOTE] That's a pretty creative idea
If you enter the second word wrong on purpose then you can't guarantee that it goes to the book. The unknown words are asked many times and if they mostly don't match then the word will be asked for so long that they know it is correct. So to get 1 word wrong in 1 book it takes so much effort to actually achieve that.
