Visual Illusion: The New Frontier in CAPTCHA Security
Combating LLM-powered attacks with human visual perception advantages
IllusionCAPTCHA leverages visual illusions to create security challenges that humans can solve but AI systems struggle with, effectively addressing vulnerabilities in traditional CAPTCHAs exposed by advanced LLMs.
- Exploits the gap between human visual perception and machine vision capabilities
- Demonstrates strong resistance against state-of-the-art LLM-based attacks
- Maintains high usability for legitimate human users
- Provides a practical, deployable solution for online security systems
This research is crucial for security professionals as it offers a new approach to distinguishing humans from increasingly sophisticated bots, helping protect online services from automated attacks while maintaining accessibility.
