Luis von Ahn is the founder of reCAPTCHA
Invented in 2003 to stop spamming on the internet.
He is a professor and his research includes CAPTCHAs and Human Computation.
Meaning of Captcha is –
Completely Automated Public Turing test to tell Computers and Humans Apart.
What is a Turing Test ?
Turing test – is a test of a machine\’s ability to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human.
When millions of people started solving reCaptcha, their founders started thinking about applying the power of human brain for something more useful.
They decided to use it for scanning and converting old books to digital books
This Project Was Named reCaptcha and its slogan was – \”Stop Spam and Read Books\”
In the year 2009 Google Acquired Recaptcha to use its digitizing power and converting old books and
news papers to digital.
Power of computers is increasing at a rapid rate and some bot programs were able to solve these CAPTCHA images.
Hence a new and improved reCAPTCHA was introduced which was called as No Captcha reCAPTCHA.
CAPTCHA Images were imposiible to be solved by blind people.
CAPTCHA Images for also super annoying for dyslexic people.
We have prepared a video presentation on reCaptcha as well :
