Block chain Based Framework for Document Verification

Abstract

Document Verification using Blockchain Technology has a huge scope. With increasing documents generated every year, there is no systematic and simple way to verify the documents. This system could be used to the governments, organizations, employers and basically anybody who wants to verify that the given document is not forged. This could be used to verify all kinds of immutable records ranging from attendance records, birth certificates, graduation and academic credentials. The proposed system could be used by the government to construct a decentralized network to store and maintain record. This is also the best way to ensure that the documents exist in the state of their creation, that they are not tampered with by anyone. Motivated by this, we propose to develop a decentralized blockchain system using Ethereum that will serve as an application to authenticate the documents. An application will be installed to local systems in which the users will verify the documents. These local systems also known as “Nodes” or “Blocks”.Once the documents are added to blocks forming the blockchain, complex calculations are performed to find the unique hash for that particular document.This concept can be implemented through decentralized applications deployed on the blockchain. The blockchain that is intended to be used for the deployment process is the Ropsten Ethereum Network. Thus, the immutability of documents can be maintained, while providing a simple, yet secure way for authenticating/verifying documents.
