Resource-Centric Authorization Scheme for Granular Access Control

The patent inverts the conventional access control approach by shifting the authorization focus from user identity to resource identity. Instead of asking 'what can user X do?', the system asks 'who can access resource Y and what operations are permitted?'. This inversion is implemented through resource-centric authorization records that store permissions associated with resources rather than users, allowing granular control over specific resources while simplifying the authorization model for resource-centric environments.

The patent segments the authorization system into distinct components: resource records with embedded authorization information, role definitions, and permission records. Each resource can have its own authorization record containing specific permissions (read, write, delete, etc.), while roles group multiple permissions together. This segmentation allows granular control at the resource level while managing complexity through modular organization of authorization data and operations.

The patent implements preliminary action by pre-defining roles with associated permission sets before authorization decisions are needed. When a user is assigned a role, their permissions are determined in advance through role assignment rather than evaluating individual permissions at access time. This pre-computation of authorization relationships reduces processing overhead during actual access operations while maintaining flexibility through the ability to assign multiple roles and combine their permissions.
