Evaluating Blockchain's Potential for Secure and Effective Digital Identity Management

Abstract

The conventional core digital identity management structure (DIMS) is vulnerable to hazards like disintegrated identity, single point of breakdown, inner assaults, and security leaks. Arising blockchain innovation enables DIMSs to be executed in it, which helps many of the issues triggered via the core 3rd party, yet its built-in openness and absence of security constitute significant challenges to DIMSs. In this context, this study uses smart contracts as well as zero-knowledge proof (ZKP) techniques to enhance the present assert identity framework on the blockchain to achieve identity unlink ability, successfully preventing the disclosure of characteristic possession. In addition, we apply BZDIMS, a framework model that enables users to specifically open up their control of characteristics to service providers to safeguard users’ conduct security. When contrasted with the previous framework, our approach accomplishes successful characteristic security safeguarding and a broader usage opportunity based on performance and security assessment.
