A Blockchain-Based Decentralized Document Authentication System for Multiple Organizations

Due to the ease with which false documents can be produced, strict verification and authentication procedures for some original documents may be required. A well-crafted fake document is never easily identified. As a result, a secure method of document verification is crucial. It is possible to cut costs and reduce document verification time from days to a few seconds by utilizing blockchain technology. Blockchain is a decentralized peer-to-peer network that provides security, dependability, authenticity, immutability, and transparency. It is resistant to modifications by design. This work involves developing a complete decentralized blockchain-based document verification system for multiple organizations. The project is built on the Ethereum public blockchain, which makes it flexible and suited for cooperation between various parties. We have used the InterPlanetary File System (IPFS) to store crucial documents. IPFS uses a decentralized protocol, which helps us achieve our goal of making a completely decentralized system. The backend of the system is a website developed on the React framework. The developed system is for multiple organizations. It has an admin verification system, which includes a payment system. Multiple organizations can control their separate platforms with different verifier panels from their own organizations. Only the admin can add verifiers to the system. He/she can choose suitable candidates from all the profiles created by that organization and give the person the authority to check the authenticity of the uploaded documents. The Admin adds a verifier with the person’s wallet address. The uploaded documents get checked by authorized verifiers. The status of the document, whether it is an authentic document or not, is determined by the votes of 50% of the verifiers. This system can verify the authenticity of documents of all kinds more securely than any other conventional system.
