oAuth
"Health Resource Authorization & Access Governance Platform"
oAuth is a robust authorization engine designed for health systems, providing granular control over who can access what, when, and how. It manages permissions down to the resource and action level—covering applications, user interfaces, endpoints, APIs, and clinical data access—while supporting temporary sharing and session-based constraints.
Core Vision & Purpose
In modern health IT infrastructures, enabling interoperability is not enough — access must be governed with precision and context-awareness. oAuth's mission is to provide:
Fine-grainedAccess control to FHIR resources
GovernanceOver application-level permissions and UI actions
SupportFor short-lived, consented access windows
ClearAudit trails and revocation capabilities
oAuth acts as the gatekeeper and orchestrator of access rights across the health information environment, ensuring secure, transparent, and auditable interactions across users, systems, and data assets.
What is oAuth?
With oAuth, healthcare organizations can precisely define and enforce permissions within complex ecosystems, ensuring secure, transparent, and auditable interactions across users, systems, and data assets. It provides policy-based enforcement integrated with clinical and administrative systems.
Strategic Benefits
oAuth delivers comprehensive authorization benefits that transform healthcare access governance and security.
Security with Precision
Minimize over-broad access and reduce risk by tightly scoping permissions to specific resources and actions
Dynamic & Context-Aware Authorization
Adapt to changing scenarios (e.g., emergency override, temporal access) without code changes
Seamless Governance & Compliance
Supports audits, policy versioning, revocation, and traceability for regulatory compliance
Reduced Complexity for Developers
Offload authorization logic to central engine; UI and API developers don't need to embed access checks everywhere
Scalable Across Organizations
Works across multi-tenant healthcare systems, federated organizations, and national health networks
Enabling Interoperable Ecosystems
Ensures that external apps and systems adhere to the same rules and can't bypass internal governance
Core Capabilities
Resource-Level Authorization
Control access to FHIR resources (e.g., Patient, Observation, MedicationRequest) at a per-user, per-application level. Define who can read, create, update, delete, or search each type of resource.
UI & Action-Level Control
Define which buttons, screens, UI modules, or actions (like "edit note", "approve order") are enabled for each user role or application context. Map UI interactions to backend APIs for enforcement.
Temporary Access / Consent Windows
Issue short-duration tokens or scoped access grants (e.g. valid for 1 hour) to share specific resources securely for a defined time. After expiration, access is automatically revoked.
Policy & Role Engine
Define fine-grained authorization policies based on user role, organizational affiliation, context (e.g. emergency mode, location, time), and attributes (e.g. patient consent status, data sensitivity). Policies can be hierarchical, overrideable, and version-controlled.
API Gateway Integration
Intercept incoming API calls and enforce authorization decisions before forwarding to backend systems. Map endpoints to resource permissions and policy sets.
Audit, Logging & Revocation
Maintain logs of every authorization decision: who accessed what resource, which action, when, and under which policy. Provide runtime revocation capabilities (immediate termination of access if needed).
Use Case Examples
oAuth enables comprehensive authorization scenarios across various healthcare environments and access patterns.
FHIR Resource Access Control
Granular permissions for Patient, Observation, and MedicationRequest resources by user role
SMART on FHIR Integration
OAuth profiles and scopes for app-based access with existing IAM solutions
Emergency Access Override
Context-aware emergency mode access with automatic audit trail generation
Temporary Resource Sharing
Time-limited access grants for specific resources with automatic expiration
Multi-Tenant Governance
Cross-organizational access control for federated healthcare networks
API Endpoint Protection
Gateway-level authorization enforcement before backend system access
Strategic Benefits
Security with Precision
Minimize over-broad access and reduce risk by tightly scoping permissions.
Dynamic & Context-Aware Authorization
Adapt to changing scenarios (e.g., emergency override, temporal access) without code changes.
Seamless Governance & Compliance
Supports audits, policy versioning, revocation, and traceability.
Reduced Complexity for Developers
Offload authorization logic to central engine; UI and API developers don't need to embed access checks everywhere.
Scalable Across Organizations
Works across multi-tenant healthcare systems, federated organizations, and national health networks.
Enabling Interoperable Ecosystems
Ensures that external apps and systems adhere to the same rules and can't bypass internal governance.
Example Use Cases
A mobile app with limited "read-only" permissions to a patient's medications and allergies
A referral system that grants a specialist access to a patient record for a defined 24-hour window
UI-level permissions disabling "order lab test" buttons for certain roles
Emergency break-glass access that temporarily elevates access with logging and time limits
Revoking access when a professional role changes or when consent is withdrawn
Centralized policy updates propagating across multiple clinics and EHR systems
