blockchain-based decentralized document issuance system. By securely storing verified citizen data on a distributed ledger, the system seeks to streamline document issuance, enhance data security, and improve transparency.
significant inefficiencies when verifying their identity across multiple institutions, as the Know Your Customer (KYC) process requires repeated submission of identical personal information. This research proposes an innovative distributed ledger solution to address these redundancies. The system enables initial KYC verification data to be securely encoded on a blockchain network, allowing individuals to subsequently access their authenticated records through password verification for future identity requirements. After completing an initial verification with any financial institution, critical personal information— including identity confirmation, residential details, and financial records—becomes securely available on the distributed network. For subsequent verifications (such as new account establishment or credit applications), customers can authorize access to their previously validated information without resubmitting documentation, dramatically improving processing efficiency. The distributed and permanent nature of blockchain technology provides enhanced security, transparency, and confidentiality while reducing vulnerability to information breaches. This approach offers financial organizations reduced operational expenses, stronger regulatory compliance, and a self-validating system that preserves data integrity while enhancing customer experience.
The proposed system consists of the following key components:
Smart Contracts: Self-executing agreements that automate document issuance and ensure data integrity.
Citizen Portal: A user-friendly platform enabling individuals to access their stored data and apply for government documents seamlessly.
2.1 Hyperledger Fabric (HLF) Hyperledger Fabric (HLF) is a permissioned blockchain framework that is particularly well-suited for government applications involving multiple authorized entities. It enables government agencies to verify and issue documents while ensuring data privacy and controlled access. HLF supports private transactions and selective data sharing, allowing institutions to regulate access based on predefined roles. Key features include permissioned access, ensuring that only authorized entities participate
The conventional method for issuing government documents in India is often plagued by inefficiencies and errors due to repetitive data entry. Citizens must repeatedly submit their personal information for each document application, leading to wasted time and an increased risk of data breaches and inconsistencies.
