BlockID: Blockchain based Digital ID and Authentication System for Privacy Improvement

Abstract

With every industry finding better applications of blockchain, it has become increasingly essential to explore its potential. Security and immutability are some of the properties of blockchain that make it very popular among companies moving to decentralized systems. An architecture for user identity management system based on blockchain that backs authentication has been proposed in this paper. A simulation justifies the use of blockchain for identity purposes. This provides a way to use this system in many industries such as storage of medical health records, a means to provide SSO ability, etc. Basic authentication of a user can take place in matter of seconds and the best part of such a system is that a user is in control of their identity.
