AB - The rapid progress of digital transformation has expanded the scope and application of personal privacy data across diverse industry sectors, creating a growing demand for secure mechanisms for data storage, management, and verification. Traditional centralized personal privacy information authentication models remain vulnerable to data breaches, unauthorized tracking, and excessive reliance on service providers as trusted entities. To overcome these limitations, this study proposes a privacy-preserving personal data protection system that integrates Zero-Knowledge Proofs(ZKP) with blockchain technology. The proposed approach enables users to prove specific attributes without exposing sensitive personal information while ensuring integrity, trace resistance, and decentralized trust through blockchain. The system incorporates a ZKP-based authentication protocol, a blockchain structure for public-key storage, an on-chain/off-chain hybrid data management model, and a username-based public-key retrieval mechanism. A prototype implementation demonstrates effective data minimization, improved integrity assurance, and enhanced anonymity. The results indicate that the proposed framework can be extended to various domains, including decentralized identity (DID) systems and public-sector digital services.
