Abstract
Identity management is the process of setting and organizing the roles and access privileges of a user’s identity. The current identity management system is centralized and is controlled by a single entity. Users’ privacy concerns are not in their best interest. Users have very little to no control over their data. The centralized system becomes a single point of failure which is prone to attack that leads to users losing their data privacy if these centralized systems are breached. Therefore we propose a Blockchain-based decentralized Identity Management System that makes use of self-sovereign identity, decentralized identifiers, and verifiable credentials. It also gives users the ability to choose from a very large number of identity providers instead of just a select few corporations. The main advantages of the proposed solution include the elimination of the need for a central authority for identity verification and identity data management, the reduction of time spent on identity verification, the ability to share data with permission, and the ability to verify the origin of the data while sharing.
