Identity Management Service Based on Blockchain and Smart Contracts to Recover Dynamic Identities and Multiple Identities

Abstract

With modern technological advancements, people tend to represent themselves digitally, and that lead to the concept of ”Digital Identity.” A digital identity represents a real-world entity and its properties (so-called identifiers) so that it can be uniquely identified digitally without the physical presence. These entities can either be individuals or organizations as well. IdM services emerged in order to manage these digital identities. They try to map the complicated real-world identities into digital identities, keeping track of the authenticity of data circulated. This is not as simple as it looks, and not every IdM service is as secure as it seems. One of the most reliable and secure implementations for such services is considered the decentralized blockchain based IdM services, due to their peer-to-peer authentication and global availability. In this research, we are proposing a robust lost identity recovering approach to implement in a decentralized IdM service which is having the capability of handling dynamic and multiple identities
