CAPTCHA Plugins in WordPress

CAPTCHA  (“Completely Automated Public Turing test to tell Computers and Humans Apart”) is a type of challenge-response test. It’s used in computing to determine whether or not the user is human.

This user identification procedure has received many criticisms, especially from disabled people. But it also received complaints from other people who feel that their everyday work is slowed down by distorted words that are difficult to read. It takes the average person approximately 10 seconds to solve a common CAPTCHA.
