reCAPTCHA - Just brilliant!
Oki, what does CAPTCHA mean?
Captcha is an automated method to determine if the software user is a person or a computer program.
Actually, are those annoying codes that you have to type, lets say, when you have to confirm a password.
200 million of this Captchas are typed every day!!!
Luis von Ahn, one of the people that invented Captcha came with a great idea: reCAPTCHA.
Now, what does reCAPTCHA project:
reCAPTCHA is a free CAPTCHA service that helps to digitize books, newspapers and old time radio shows. The scanner can’t recognize all the words if it’s an old book or newspaper, so it needs the help of humans.
The next time you have to type one of this, don’t be frustrated, you practically write a book.
