1. CAPTCHAs generate tests that are easy for humans but difficult for computers by distorting text in images. 2. The term CAPTCHA was coined in 2000 by researchers who wanted to automatically distinguish humans from bots on the internet. 3. CAPTCHAs work by generating random text, displaying it distorted in an image, storing the text, having the user enter it, and checking if the entered text matches what was stored. If it matches, the user is verified as human.
