Media Identity, Provenance and Embedded Trust

Client:Confidential technology programme· Engagement:OEM scientific and engineering development

Challenge

Associate media with identity, provenance, integrity and controlled information while it is distributed and transformed.

Why the problem is difficult

Provenance must survive transformation and adversarial handling within a clearly stated threat model.

DBRF OEM contribution

Information-embedding concepts, provenance models, tamper evidence, security architecture, rights/workflow mapping and application design.

Approach

  1. 01Model the threat and verification boundary
  2. 02Design embedding and tamper evidence
  3. 03Map rights and workflow
  4. 04Design application integration

Work packages

  • Information-embedding concepts
  • Provenance models
  • Tamper evidence
  • Security architecture
  • Rights/workflow mapping
  • Application design

Evidence and validation boundary

Blockchain is not claimed to be inherently required, and provenance is not claimed to guarantee truth. The threat model and verification boundary are stated per record.

Claims discipline: Do not claim that blockchain is inherently required or that provenance guarantees truth. State the threat model and verification boundary.

IP / rights statement

Developed as an OEM scientific and engineering contribution. Technology and intellectual-property rights remain with the applicable contracting or rights-holding organisation. DBRF does not claim ownership unless expressly stated in a verified record.
