Why Does CAPTCHA Exist to Verify Humans?

💡 The Answer

• CAPTCHA stands for 'Completely Automated Public Turing test to tell Computers and Humans Apart.'
• It prevents bots from abusing online services like creating fake accounts or posting spam.
• The test uses distorted text or image recognition that is easy for humans but hard for computers.
• reCAPTCHA later used these tests to help digitize books by having humans read scanned words.
