Private Captcha offers a user-friendly CAPTCHA solution that protects forms and APIs while maintaining high privacy standards without requiring extra integration efforts. Instead of asking users to solve complex puzzles or track their behavior, Private Captcha solves an invisible cryptographic task in the background. The system automatically adjusts the task difficulty, ensuring smooth access for real users while making it too costly for bots to attempt. Cryptographic task provides equal security regardless of bot's intelligence level, making it effective even as AI technology improves.
