Google has acquired ReCaptcha, one company behind the distorted text boxes found at the bottom of many website sign-in pages.
Terms of the deal were not disclosed but Google plans to use ReCaptcha's technology both as a security measure within certain Google sites and to make its massive book-scanning project a little smarter, the company said in a blog post. ReCaptcha is an offshoot of Carnegie Mellon University's School of Computer Science, and puts a twist on the traditional captcha: a string of letters in squiggly text meant to confuse spam bots and other nonhuman web pests.
The idea behind a captcha is to confuse a computer but computers are also confused by some words written in old fonts. ReCaptcha offers two words, one of which is a captcha it already knows, and one of which is a word it doesn't know. The thinking is that if you get the first word right, you're likely to be a human and you're also probably going to get the second one right.
It can then pool all the answers for the second word and declare with a reasonable amount of certainty that the second word is what most people think it is, thereby updating the vocabulary of participating book scanners. This is of obvious interest to Google, in light of its book scanning project.

So Google will give out the Recapture system for free to websites to use and then populate the second word with scans it cannot understand froim its book scanning project. So we, the public, will be identifying words its book scanning software cannot.
Utter genius.
