What is Captcha and how does it work?
Captcha, which stands for Completely Automated Public Turing test to tell Computers and Humans Apart, is a challenge-response test designed to determine whether the user is human. It works by presenting a series of visual or auditory challenges that are easy for humans to solve but difficult for computers. The most common type of Captcha is a visual challenge that requires the user to identify and enter a series of characters or numbers that are distorted or obscured in some way. This is intended to prevent automated programs, such as bots, from accessing a website or system.
The Captcha system uses a combination of image recognition and machine learning algorithms to generate and validate the challenges. When a user attempts to access a website or system that uses Captcha, they are presented with a challenge that has been generated by the system. The user must then enter their response to the challenge, which is verified by the system. If the response is correct, the user is granted access to the website or system. However, if the response is incorrect, the user may be presented with additional challenges or blocked from accessing the site. The goal of Captcha is to prevent automated programs from accessing a website or system, while still allowing human users to access it easily.
