CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a valuable tool in the world of online security. It effectively distinguishes between humans and bots, ensuring a safer online experience. CAPTCHA works by presenting users with tests that assess their ability to solve challenges that are easily understood by humans but difficult for automated bots. This verification process provides an additional layer of security, preventing unauthorized access, data breaches, and other malicious activities. CAPTCHA is widely used in user authentication, preventing brute force attacks, and safeguarding sensitive information. Implementing CAPTCHA significantly enhances online security, protecting users and platforms from potential threats.#32#
