Decentralized Digital Identity Wallet using Principles of Self- Sovereign Identity Applied to Blockchain

Abstract

Human dignity demands that personal information be hidden. Currently, due to the dominance of large internet companies/cloud service providers, the control over the identity is not with the identity holder, leading to privacy concerns. The need for decentralization of identity is because it gives back control of identity credentials to identity holders and allows them to control when, how, and with whom to share their credentials. Self-sovereign Identity is an arising concept, which provides a way for digital identification. It enables the entities to control their identity and data flow in the digital world while enhancing privacy and security. Major privacy concerns are because of the numerous attacks and data breaches that can happen when sensitive information like identity credentials is stored on a centralized system used by the existing systems. Therefore, we propose a blockchain based self-sovereign identity platform where the user’s mobile wallet application. The proof of the Identity credentials are kept in a decentralised storage system based on the blockchain. This platform provides a Zero-Knowledge Proof (ZKP) mechanism to verify the information.
