CAPTCHA (reCAPTCHA)

What is CAPTCHA?

CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a security measure that distinguishes human users from bots. reCAPTCHA is a Google-developed version that uses advanced risk analysis to verify users.

Why is CAPTCHA Important?

CAPTCHA helps:

• Prevent Spam: Blocks automated bots from submitting forms or creating accounts.
• Protect Websites: Reduces the risk of brute-force attacks and data scraping.
• Improve Security: Ensures that only legitimate users can access sensitive areas of a website.

Brief History of CAPTCHA
