Enhancing Digital Identity Through Blockchain: A Conceptual Framework for Trust, Privacy, and Interoperability

Abstract

Contemporary digital environments are supported by digital identities to enable secure access to, for example, governance, healthcare, and finance applications. Nevertheless, such centralized, lack of user control, noninteroperable identity systems are drawbacks of present identity systems. In this paper, we present a decentralized, privacy- preserving, and inter-operable identity model as part of a conceptual framework for the blockchain based approach on the above-mentioned problems. To enhance trust and compliance, the framework also utilises consent-based mechanisms, layered-architecture and self-sovereign principles. Real-world use cases are described to illustrate the utility of the model in real life applications such as cross-border identity verification, sharing of health data, and validation of educational credentials.
