Hierarchical Sovereignty Management and Access Control based on Self-Sovereign Identity

Abstract

Self-sovereign identity is a type of decentralized identity technology and has been proposed to solve
various problems of the existing public key infrastructure based centralized identity authentication
service. In addition, the demand for a secure decentralized access control management (ACM)
technique has increased according to the demand for such next-generation identity identification
service. Accordingly, although various ACM techniques that can be applied to decentralized services
have been proposed, most fall into the introductory stage of research. In this paper, based on the
SOVRIN-based restructured verifiable credential concept proposed in our previous study, we provide
a hierarchical sovereignty and ACM technique that does not use a smart contract.
