EVALUATION OF CAPTCHAs

CAPTCHAs are known as Captcha which stands for Completely Automated Public Turing test to tell Computer and Human Apart. CAPTCHAs are used to prevent automated scripts from harvesting email addresses from publicly accessible forms on the internet and submitting them to spammers. CAPTCHAs are mostly utilised because computers have a difficult time deciphering the text concealed behind distorted visuals, but humans have an easier time deciphering the information hidden behind the distortions. As a result, the optimal response to a CAPTCHA assignment is considered to be a human return, and the individual is permitted entry to the website in question. The CAPTCHA is a useful tool for determining which clients are human and which are computer programmes.
