HIERARCHICAL UNIVERSAL RESOLVER SYSTEM FOR DECENTRALIZED IDENTITY ENVIRONMENT AND METHOD THEREOF

摘要

Proposed is a decentralized identity technique, and more specifically, are a hierarchical universal resolver system for a decentralized identifier environment and a method thereof, which can control access to connected decentralized ledger information and prevent exposure and leakage of the information by hierarchically managing a universal resolver (UR) in an identity verification system based on self-sovereign decentralized identifiers (DID). According to an embodiment, accessibility to private information in a blockchain network in which decentralized ledgers are stored, as well as privacy of certificate or identification information based on decentralized identifiers, may be complemented.
