Blockchain-based Document Verification Scheme for Enhanced Security and Fraud Control

In this day and age of digital technology, the verification of documents plays an essential part in a variety of spheres, including the validation of identities, legal contracts, academic credentials, and financial transactions. Traditional document verification methods often face security issues, data tampering, and fraud. This research proposes a Blockchain-Based Document Verification Scheme (BBDVS) to improve document verification security and fraud management. This addresses concerns. The BBDVS uses blockchain technology's immutability and decentralization to create a safe, public document verification platform. Cryptography ensures the integrity, validity, and non-repudiation of checked papers. Smart contracts, blockchain-based self-executing agreements, automate and expedite verification. A prototype system is built and tested to determine BBDVS efficacy. The system simulates various document verification scenarios. Compared to conventional approaches, this technology is more secure, efficient, and reliable. It also shows how the scheme may avoid fraud, decrease costs, and simplify document verification for various businesses. The research found that the BBDVS may significantly improve fraud control and document verification security. This strategy could revolutionize document verification in banking, healthcare, education, and government services. More research is needed to solve the scalability, privacy, and regulatory issues that arise when implementing blockchain-based systems on a large scale.
