Content Provenance - AI & Media Authentication
FHE-powered content provenance tracking for AI models, generated outputs, and media.
Implements: PIP-0011 / LP-7110
Features
- Model Sealing: Register AI model manifests (weights, architecture, training data) with FHE-encrypted version
- Output Attestation: Prove AI output came from a specific model via homomorphic comparison — model ID never revealed
- Media Chain: Track full provenance from point-of-capture through every edit
- Derivation DAG: Directed acyclic graph of content lineage
Content Types
| Type | Description | Example |
|---|---|---|
| AIModel | Model weights/architecture | GPT checkpoint |
| AIOutput | Generated content | Text, image, code |
| MediaCapture | Point-of-capture media | Photo from device |
| MediaEdit | Edited derivative | Cropped, filtered |
| Document | Text document | Article, report |
Quick Start
npm install
npx hardhat compile
npx hardhat test
# Deploy
npx hardhat task:deploy
# Register a model
npx hardhat task:register-content --contract <addr> --hash 0x... --type 0
# Register AI output
npx hardhat task:register-content --contract <addr> --hash 0x... --type 1 --model 42
# Attest output origin
npx hardhat task:attest-output --contract <addr> --output 1 --model 42
# View provenance chain
npx hardhat task:verify-provenance --contract <addr> --id 0
