Abstract - The rapid growth of digital transformation has significantly increased the use of electronic documents in sectors such
as education, healthcare, finance, and legal services. However, the centralized storage and management of digital documents make them vulnerable to forgery, unauthorized modification, and data breaches, leading to serious concerns regarding trust and authenticity. Traditional document verification system relays heavily on intermediaries and centralized authorities, which may introduce delays, inefficiencies, and security risks. Block chain technology offers a decentralized, immutable, and transparent framework that ensures document integrity and tamper resistance. This study explores blockchain-based techniques for secure document verification by utilizing cryptographic hashing, distributed ledgers, and smart contracts to authenticate documents without the need of third-party verification. The proposed approach enhances transparency, improves trust among stakeholders, and enables real-time verification of Document authenticity. Furthermore, this works analyses existing blockchain-based document verification models, highlighting their advantages, limitations, and practical challenges. The finding demonstrates that block chain technology can significantly improve the reliability, security, and efficiency of digital documents verification systems. This research provides a strong foundation for developing scalable, secure, and trustworthy document authentication solutions for future digital ecosystems.
Key Words: Block chain, Document Verification, Cryptographic Hashing, Smart Contract, Decentralized Systems, and Privacy Preservation.
1. INTRODUCTION Document verification plays a critical role in modern digital ecosystems, ensuring the authenticity and integrity of sensitive information. Documents such as educational certificates, identity proofs, legal contracts, and medical records are fundamental for decision-making processes across various domains. Any compromise in document verification may lead to serious consequences, including identity theft, fraud, and legal disputes. Therefore, establishing secure and reliable document verification mechanisms is essential to maintain trust and prevent misuse. Traditional document verification systems are typically centralized and managed by a single authority or organization. Verification often requires manual intervention or reliance on third-party intermediaries, which can introduce delays, inefficiencies, and single points of failure. Moreover, centralized systems lack transparency and are vulnerable to data manipulation, unauthorized access, and cyber-attacks. These limitations highlight the need for more secure, transparent, and efficient verification framework.
