        abstract = {Digital documents are widely used in education, business, law, and government, but they can be easily copied, edited, or misused. Traditional verification systems depend on centralized databases, which create security risks and do not provide clear proof of authenticity. To solve this problem, this paper presents a blockchain-based document protection system that ensures secure storage, verification, and tracking of digital files. The system uses SHA-256 hashing to generate a unique fingerprint for each document and stores it on the Ethereum blockchain through smart contracts. The actual file is uploaded to IPFS, providing decentralized and scalable storage. A QR code is generated for every document, allowing quick public verification through a web interface developed using Flask. Audit logs, role-based access, and encryption further improve transparency and security. Testing shows that the system is reliable, tamper-proof, and efficient for real-time verification. This framework can be applied to certificates, legal records, academic documents, and forensic data, offering a trustworthy solution for institutions that require secure digital document management.},
