Zero-Knowledge Proofs (ZKPs) are a cutting-edge cryptographic technique that enables secure authentication in online applications—such as e-commerce platforms, online banking, social media, cloud storage, and SaaS platforms—without revealing sensitive information. This study explores the application of ZKP-based authentication methods to enhance web security, particularly in mitigating risks such as data breaches and identity theft. We present a comprehensive analysis of ZKP principles, critically evaluate existing approaches, and introduce a novel Zero-Knowledge Proof-based Verification and Authentication (ZKPVA) protocol specifically tailored for web applications. The workflow of the proposed framework is visually illustrated and compared with existing methods to emphasize its efficiency and security benefits. Our findings highlight the critical role of ZKP-based authentication in protecting sensitive data while meeting the growing demand for robust and efficient security solutions in modern web applications.
