Abstract

Document verification and authentication plays a vital role in everyday life. These documents can be any type like educational certificates, business transactions, images containing seals, billing receipts, tenders, etc. Scams on documents could have happened in any stage of transactions. Currently, the blockchain became a trustable secure mechanism for maintaining and giving up the data in a distributed, immutable, and trustable way without any intermediaries. Blockchain keeps all business across two parties in a confirmable and unchangeable. Because of that transparent and trustable nature many fields like medicine, finance, education, insurance, procurement, and supply chain handling their transactions by blockchain mechanisms. In this research, an identity management system has been framed for any type of document verification and validation using blockchain technologies like hyperledger and IPFS algorithms. Existing identity-based security methods having some drawbacks like leakage, forgery of confidential documents. Facial recognition and extracting the specific features could provide the uniqueness and protecting the documents used. By applying blockchain methods in identity-based authentication improves security with the increase in the speed of transactions at lower cost with high performance.Analyzing hyperledger and IPFS results yields a secure framework for identity-based document verification systems. Implementation results have shown the specific advantages of both blockchain methods.
