Developing a Privacy-Focused and Engaging Captcha

Existing CAPTCHAs often trade-off between user experience and privacy. Google's reCAPTCHA, while user-friendly, falls short on privacy. Alternatives like Friendly Captcha, despite being GDPR-compliant, can be expensive, and traditional CAPTCHAs frustrate users with their complexity.

I've developed an alternative for withoutbg.com, a background removal API service. My custom CAPTCHA asks users to select foreground objects in images, offering a middle ground between engaging users and deterring bots.

Technical Details: I used a collection of joyful, Unsplash-sourced images (think ice cream, kites, etc.) that occupy a small portion of each image. Each image comes with a corresponding mask that defines the foreground region. When a user clicks on an image, I validate the click by checking if the coordinates fall within the masked foreground region. This approach not only enhances user engagement but also ensures a bot deterrence mechanism.

Check it out and let me know your thoughts. I'm seeking constructive feedback to improve it further.

It seems image segment AI should be able to bypass the bot detection
