Securing Digital Identities System through Blockchain Networks

Abstract

The increasing importance of blockchain technology as an improvement in efficiency, security, and transparency across different fields has notably made a difference in identity and access management systems. Traditional security don’t extend sufficient protection, mainly because threats have become sophisticated. Decentralisation and cryptographic mechanisms assure the integrity of data and eliminate single points of failure offered by a blockchain. This paper highlights the transformative role of blockchain technology in cybersecurity, especially with focus on smart contracts, secure authentication techniques, and decentralised identity management. The paper provides an insight into technological advancements, challenges, and trends with respect to bolstering security and trust in online transactions. It goes a step further to evaluate the viability of implementing blockchain-based identity management systems by the corporate world and governmental organisations and takes into account factors including scalability, regulatory compliance, and user adoption.This paper also proposes blockchain based vehicle identity system using Practical Byzantine Fault Tolerance (PBFT) and Directed Acyclic Graph (DAG ) Consensus
