Blockchain-Based Identity Management: Enhancing Security and Privacy in Digital Transactions

In the era of digital transformation, there are significant risks accompanying with secure communication between users, services, and devices via centralised digital organisations. To ensure that digital identities are secure and private, digital identities must be authenticated and verified. Identity management solutions are extensively employed in real-world applications, and they are usually made to make dealing digital identities and tasks like authentication simple. In the last several years, new concepts of Identity Management have emerged as an outcome of Blockchain technology, which has occurred as one of the greatest technological advances of the twenty-first century. These concepts aim to address privacy and security concerns while also enhancing decentralisation and user control in transactions on Blockchain frames. In this article, we provide a Blockchain-based decentralised and transparent structure for securely managing digital identities. We also discuss at a summary of identity management techniques, providing a summary of the architecture and discussing blockchain technology as a distributed user-centric identification solution. The objective of this paper is to discover how blockchain-based technologies may be used to increase security and privacy while managing the problems associated with identity management in digital transactions.
