Abstract:
The utilization of machine learning (ML) techniques within CAPTCHA systems represents a significant advancement in cybersecurity, offering dynamic adaptability to thwart evolving adversarial attacks. This research delves into the integration of ML defenses within CAPTCHA frameworks, focusing on their efficacy in adjusting challenge difficulty dynamically to counter sophisticated attacks. By leveraging ML algorithms, CAPTCHA systems can analyze user behavior patterns and adaptively tailor challenges to deter automated bots while ensuring user accessibility and engagement. This paper aims to provide a comprehensive investigation into the design, implementation, and evaluation of ML-based CAPTCHA defenses. It explores various ML approaches, including supervised learning, reinforcement learning, and deep learning, in dynamically adjusting challenge complexity based on user interactions and environmental factors. Furthermore, the study delves into the assessment of ML-driven CAPTCHA systems' resilience against adversarial attacks, such as machine learning-based algorithms, optical character recognition (OCR) techniques, and adversarial image manipulation. Through empirical analysis and experimentation, this research endeavors to elucidate the effectiveness and limitations of ML-based CAPTCHA defenses in real-world scenarios. By elucidating the intricacies of integrating ML techniques within CAPTCHA systems, this paper seeks to contribute valuable insights to the field of cybersecurity, offering guidance for the development of robust and adaptive CAPTCHA mechanisms capable of mitigating emerging threats in the digital landscape.
