Abstract
This study aims to delve into the knowledge graph, functional pathways, and qualitative logic among elements such as network trust, blockchain organization, user identity, big data, and information security in the digital economy era. Through an analysis of the endogenous and exogenous explicit management logic relationships among these elements, this study innovatively constructs three primary dimensions and nine secondary dimensions of digital identity attributes for users. Additionally, it establishes a collaborative management mechanism between government organizations and non-governmental blockchain alliances corresponding to identity attributes based on the delegated proxy mechanism. Furthermore, it reconstructs the big data chain management framework for user digital identity under the zero-trust model and establishes a management process for blockchain digital identity information security protection under the zero-trust model. These efforts provide innovative solutions with both research and application value for the “virtual-real integration” global security governance of the metaverse, digital economy, and digital government.
