Administration of Digital Identities Using Blockchain

Abstract

Since the last two decades, the problem of check theft and the data breaches from centralized systems has gotten worse. In this study, we looked at how blockchain technology is employed in identification systems and how it may be applied to verify an identity’s veracity and legitimacy. The drawbacks of the conventional identification systems were examined in depth, and the advantages of using a Blockchain-based identity system were discussed, including the removal of the middleman and the need for long wait times for verification, authorization, and attestation. Nobody can alter their identification data because the nodes in a blockchain are supposed to be immutable, and because asymmetric cryptography is utilized while sharing data, personal information is kept secure. We were able to effectively establish an identity wallet-a node in a chain on the Ethereum platform-and test a self-sovereign identification system for a single person.
