  • Abstract:
  • The proliferation of digital documents and rising privacy concerns have created an urgent need for secure, confidential verification systems. This paper presents a novel approach to document verification in decentralized systems using zero-knowledge proofs (ZKPs) and zero-knowledge succinct non-interactive arguments of knowledge (ZK-SNARKs). We propose a framework that leverages the Circom ZK circuit design language and the Iden3 protocol to create a privacy-preserving document verification system. Our research explores ZK-proofs and blockchain technology, demonstrating how these cryptographic techniques can verify document integrity and authenticity without revealing sensitive information. We present a detailed analysis of Circom ZK, showcasing its efficacy in creating complex arithmetic circuits for document-related proofs. The integration of the Iden3 protocol addresses the challenges of identity management in decentralized environments. We outline the design and implementation of ZK-SNARK circuits using Circom, each tailored to specific document verification scenarios. Performance and security evaluations indicate significant improvements in privacy preservation and a reduction in on-chain data requirements, albeit with a moderate increase in computational overhead. This research contributes to the growing body of knowledge on privacy-enhancing technologies in blockchain systems and offers a practical solution for implementing secure, privacy-preserving document verification in decentralized environments.
