Decentralized identity verification: a blockchain-based framework for self-sovereign identity (SSI) with issuer trust registry

Abstract

In an era where data security and privacy breaches are alarming, blockchain technology could greatly enhance different identification systems like passports, national identity cards (NIDs), driving licenses, etc. We explore the idea of a blockchainpowered identity verification system in this research where individuals’ identity information is safely kept on a decentralized ledger. The principal goal of this research is to find out the possible advantages and difficulties of incorporating blockchain systems into personal identity verification systems. We thoroughly assess the built-in cybersecurity attributes of blockchain, including decentralization, immutability, and cryptographic security, which collectively establish it as a perfect choice for authenticating and safeguarding personal identity data. Moreover, the research dives into topics concerning data privacy, surveillance, and individual rights. The primary emphasis of this research is on the smooth incorporation of a blockchain-driven identity verification system centered on Self-Sovereign Identity (SSI). Furthermore, this thesis highlights the critical role of issuers in the Self-Sovereign Identity System (SSI) and addresses the inherent issue of Issuer Trust for verifiers. To address the issue, this study introduces the concept of an Issuer Trust Registry to ensure trustworthiness when issuing credentials. The research studies how blockchain can streamline identity verification for authentication while creating driver’s licenses, bank account openings, SIM card registrations, land registrations, etc., thereby mitigating fraudulent activities in the cyber world and enhancing overall security. When we increase the security, we can optimize the personality verification of authentication. In conclusion, this research proposes a comprehensive study of the role of blockchain technology in reimagining personal identification systems for the digital age.
