Doqfy: Digital Document Verification using Blockchain and IPFS
Devika Sawant · INTERANTIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT · 2025
Abstract—Every year, millions of students enroll in Indian higher education institutions, generating numerous certificates such as marksheets, certificates, appreciation cards, and diplo- mas throughout their academic journey. For admissions or job applications, students are required to submit these documents to institutes or companies. However, manually tracking and validating the authenticity of these certificates becomes a tedious task. In the era of AI tools and smart editing technologies, the risk of modifying scores on scorecards or forging someone else’s documents has increased. Manual document verification is not only time-consuming but also incurs paper costs and poses challenges to managing old records. There is a pressing need to address this issue and streamline the document verification process, ensuring confidentiality, reliability, and data availability. This paper suggests creating a verification system based on blockchain technology aimed at preserving data integrity. The system involves three key entities: the student, the university, and the company. The student initiates the verification process by uploading the document, and the university validates it by uploading the original document they possess. If the hash values match, the document is considered verified, and a QR code is embedded for easy sharing and verification status checks by companies. The advantages of such a system include reduced risk for students of losing or damaging certificates and sim- plified certificate validation procedures. This blockchain-based approach enhances the security, efficiency, and integrity of the document verification process.
