1179344 2011-02-19 23:20:00 Not sure if this is correct but in some cases the first word is usually a scanned word from a book and the 2nd is a digital computer made word. Apparently it only actually checks if the 2nd word is correct as the first word can be absolutely anything from symbols to signatures.

Only what I've heard though.


yep - in fact you only need to get one word typed correct - the other can be anything at all. (fake one can be first or second word)

I think there is an "extra" bit in google's one now that recognizes too many failed repeat attempts from an ip (10 I think) and then makes both words required to be correct - but I'm not sure on that.

What I do know is that they use the "fake" words from their ocr softwares that are unable to be recognized - so they use you,me and everyone else as unpaid human word recognition and digitization bots! LOL - way to go Google.


Unlike most CAPTCHA systems, Google’s uses images with two words. That’s because Google uses reCAPTCHA for two purposes. Like other CAPTCHA systems, it’s designed to frustrate spammers, but it’s also incorporated into Google’s efforts to digitize books. When a word in a book scan can’t be recognized by Google’s OCR software, it’s sent to the reCAPTCHA pool. So when a person enters a reCAPTCHA phrase into a form, Google can discover what its OCR program couldn’t, without having to hire human editors to review scanning results.

and here's another interesting link on how to pick which word is probably the "fake" :)

Still, a cool use of anti-bot measures.

I saw this one once and it required you to beat the system at Tic Tac Toe :D

1179347 2011-02-20 17:58:00 I wish those captchas were easier to read.

You may have come across the captchas that the Herald and other sites use.

The red one and the blue one.

They ask you to enter two words as a spam protection.
fair enough.
I have a captcha on my website

But those two are so hard to use, for a start most of the words are not even words, they are on crazy angles, and have formatting and punctuation that makes it very hard to decide what to enter.

And it means that one has to try several ties.

Can't they just use a simple catpatcha?

I mean they are not nuclear power stations they are trying to protect.

I hate the catpatcha thing, another step away form the user friendly internet experience.
It does nothing for the honest Joe public except annoy them.
I tend to avoid sites that use them.

1179348 2011-02-20 18:43:00 Yes but if it doesn't get used, you'll literally get a hundred-odd spam messages a day on your forums.

In which case it's an absolutely freaking NIGHTMARE for admins. It's definitely worth the slight hassle of putting your users through it during sign-up. It's a once-off, maybe 30 seconds of their life they can't get back.
