Captcha (Completely Automated Public Turing test to tell Computers and Humans Apart) is a security measure used on websites and applications to distinguish between human users and automated bots. The primary purpose of Captcha is to prevent spam, abuse, and unauthorized access by ensuring that only real humans can interact with the platform. Captcha challenges typically involve presenting users with tasks that are easy for humans to solve but difficult for bots. Here is an example of content for a captcha challenge:
Captcha Challenge: Identify the Animals
Instructions: Please select all images that contain animals from the options below.
[Multiple images will be shown, and the user needs to identify which images contain animals, such as cats, dogs, birds, etc.]
OR
Captcha Challenge: ReCAPTCHA v3
Instructions: Prove you are human by interacting with the website naturally.
[In this type of captcha, there are no explicit challenges presented to the user. Instead, the website analyzes the user's behavior and interaction patterns to determine if they are likely human or a bot.]
Please note that Captcha challenges can come in various forms, such as image recognition tasks, audio challenges, text-based puzzles, or even behavioral analysis. The specific content and format of the Captcha depend on the implementation and the level of security needed for the website or application.
