Zero-Trust Identity Management for Cloud Change Authorization

The patent segments the trust model by introducing multiple identity providers (IDPs) and distributed authorization mechanisms. Instead of relying on a single trusted component, the system divides authorization into discrete tokens issued by different IDPs, each validating specific aspects of change authorization independently. This segmentation distributes risk across multiple components rather than concentrating it in one authority.

The patent introduces an intermediary layer of identity providers and token validation mechanisms between components. These intermediaries issue and validate cryptographic tokens that mediate trust relationships, allowing components to verify authorization without establishing direct high-trust relationships. This intermediary layer reduces risk concentration by preventing any single component from having absolute authority.

The patent implements self-service mechanisms where components automatically validate cryptographic tokens and verify authorization through distributed IDPs without requiring complex centralized IAM framework management. The system performs self-validation of tokens and authorization credentials, eliminating the need for manual IAM policy management and reducing operational complexity while maintaining strong security control.

The patent replaces mechanical IAM framework controls with cryptographic token-based validation. Instead of relying on complex IAM policies, roles, and permissions that require manual management, the system uses cryptographic signatures and token validation mechanisms that automatically enforce security controls. This substitution reduces operational burden while maintaining or improving security effectiveness.
