Blockchain Based Identity Management for Secure Data Sharing

Information management products are commonly used in real-life applications along with designed to make managing digital identities as well as activities like authentication easier. There were attempts in recent years to develop BlockChain (BC)-based Identity Management (IdM) systems that allow customers to gain control other than their names. This article discusses the current BC-based IdM publications and patents that were published in 20–2023. We identify prospective opportunities and research gaps based on literature analysis, that would hopefully help inform future national policies. A card is an electronic log of communications that remains reproduced and disseminated across the BC of complete computer network systems. Because time a newfangled cargo comes on the BC, a log of that deal is attached to the periodical of the relevant contributor, each block on the chain contains several communications. However, there is still a gap in the present literature in a thorough examination of the elements of IdM in addition to user privacy and data security methods architecture for IdM. In this paper, we give a unified picture of the essential notions of SSI, including authentication techniques for diverse SSI systems and components of identity proofing.
