As an AI language model, I'm not able to generate images directly, so I cannot create a visual CAPTCHA for you. However, I can help you understand what a "CAPTCHA" is and suggest some content you might consider using in a CAPTCHA implemented with Zscaler, a cloud security platform.
1. What is a CAPTCHA?
CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart." It's a security mechanism used on websites to verify that the user is a human and not a bot. CAPTCHAs often require users to perform tasks that are easy for humans but difficult for automated programs to solve.
Show the user an image containing certain objects (e.g., cars, traffic lights, bicycles) and ask them to select all instances of a specific object. This can help differentiate between humans and bots, as image recognition can be challenging for automated programs.
Zscaler's platform may be capable of analyzing user behavior to detect bots. You can include a challenge like, "Click and hold the button for 3 seconds before releasing," which can differentiate between human behavior (holding the click) and automated behavior (instant click-release).
Present the user with a simple math problem (e.g., 6 + 4) and ask them to solve it. Bots typically struggle with solving math problems compared to humans.
Display a message like, "Click the button within 5 seconds to proceed." Bots may not react quickly enough, while humans can click in time.
For accessibility purposes, you can offer an audio challenge where the user listens to a sequence of numbers or letters and types them accurately. This can be an alternative to a visual challenge.
Remember to keep the challenges relatively easy for humans to complete quickly but complex enough to thwart automated bots effectively. The goal is to strike a balance between usability and security.
Please note that Zscaler may have their specific implementation methods and tools for CAPTCHAs, so it's essential to refer to their documentation for accurate and up-to-date information.
