Content Trust Framework Inspector (CTF Inspector)

The CTF Inspector is a proposed tool allowing users to inspect, verify, and create Provenance statements and analyze the validity of resources, especially for Trust Function developers.

Purpose​

Enables users to:

  • Inspect Provenance chains
  • Verify digital signatures
  • Analyze Trust Function scores
  • Create/edit provenance records
  • Validate CTF compliance
  • Debug trust calculations

Features​

Provenance Viewer​

Tree Visualization​

Display provenance chains graphically:

  • Agents (who)
  • Activities (what)
  • Entities (resources)
  • Time (when)
  • Relationships

Search & Filter​

  • By resource ID
  • By agent
  • By time range
  • By activity type

Signature Verification​

Check integrity:

  • Digital signature validation
  • Blockchain hash verification
  • Certificate chain inspection
  • Timestamp validation

Trust Score Analysis​

Inspect Trust Function calculations:

  • Input parameters
  • Scoring algorithm
  • Weight assignments
  • Contributing factors
  • Confidence levels

Provenance Editor​

For authorized users:

  • Create new provenance records
  • Add agents and entities
  • Define activities
  • Sign and submit
  • Preview before committing

Trust Function Development​

Tools for developers:

  • Test functions with sample data
  • Debug scoring logic
  • Compare function variants
  • Validate against requirements

Compliance Checker​

Validate resources against:

  • CTF policies
  • Regulatory requirements
  • Organizational standards
  • FHIR profiles

User Roles​
