Overview of CAPTCHA
CAPTCHA, which stands for Completely Automated Public Turing test to tell Computers and Humans Apart, is a type of challenge-response test used in computing to determine whether the user is human or not. The basic function and design purpose of CAPTCHA is to provide a simple test that is easy for humans to solve but challenging for computers and automated systems to decipher. This is crucial in protecting websites and online services from abuse by automated bots. Examples of CAPTCHAs include distorted text that users must type correctly, image-based CAPTCHAs where users identify specific objects, and logic puzzles. A scenario illustrating its use is when signing up for a new email account, where the service may present a CAPTCHA challenge to ensure the account is being created by a human rather than an automated system attempting to create multiple accounts.
