What is full form of CAPTCHA?
Answer:
COMPLETELY AUTOMATED PUBLIC TURING test to tell COMPUTERS AND HUMANS APART
Reason for using CAPTCHA - Because computers have a hard time recognizing the letters and digits which are in free style.
Idea extended to reCAPTCHA - Instead of one, it displays two images.
- One of them is for filtering out bots
- while other is actual digitized piece of text
