Hierarchical Identity Model

Definition ∞ A Hierarchical Identity Model is a structured system for managing digital identities where entities are organized in a layered or tree-like arrangement. This model assigns identities with varying levels of authority and scope, reflecting a chain of trust or delegation. It allows for efficient management of permissions and access control, with higher-level identities capable of issuing or revoking credentials for lower-level ones. This structure simplifies identity governance in complex systems.
Context ∞ Hierarchical identity models are being explored in decentralized identity solutions to provide scalable and manageable frameworks for digital credentials. Challenges include balancing decentralization with the need for structured authority and ensuring interoperability across different identity systems. This model holds promise for enhancing security and administrative efficiency in large-scale digital ecosystems, including those involving autonomous agents.
