CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. It is a security feature used on websites to prevent automated bots and spam from accessing the site.
CAPTCHAs typically consist of distorted text, images, or audio that humans can easily recognize but computers cannot. The user is asked to enter the characters they see or hear, proving they are a real person and not a bot.
CAPTCHAs are commonly used on login forms, registration pages, and contact forms to prevent spam and abuse. They are also used to prevent automated scraping of websites and to protect online polls from being manipulated.
There are various types of CAPTCHAs including text-based, image-based, audio-based, and reCAPTCHA. reCAPTCHA, developed by Google, uses advanced algorithms to determine if a user is a human or a bot.
While CAPTCHAs provide an important layer of security for websites, they can also be a source of frustration for users. Some CAPTCHAs are difficult to read or understand, causing users to make multiple attempts before successfully completing the test.
