AI Training Data Provenance

Prove your content existed before the training cutoff.
Essential for copyright claims and opt-out enforcement.

RFC 3161 timestamps + content fingerprints = independently verifiable proof of creation date.

Why this matters: NYT v. OpenAI, Getty v. Stability AI, and hundreds more lawsuits. EU AI Act requires training data documentation. Creators need proof.

The NYT v. OpenAI Problem

Content creators need to prove three things. CertNode provides all of them.

📅

1. Existence Date

"This content existed BEFORE Model X's training cutoff"

🚫

2. Consent Status

"I never consented to AI training use"

🔗

3. Derivative Proof

"AI outputs derived from my original work"

Without Timestamped Proof

Creator claims:

"I wrote this article in 2022, before GPT-4 training."

AI company responds:

"Prove it. Website timestamps can be edited. CMS records can be faked."

Enforcement is nearly impossible without independent proof.

CertNode Training Data Provenance

Four capabilities that create complete provenance for your content

📚

1. Bulk Registration

Register entire content libraries with RFC 3161 timestamps. Prove existence before any training cutoff.

POST /api/v1/training-provenance
{
"content_hash": "sha256:abc123...",
"content_type": "article",
"training_consent": "opt_out",
"registered_at": "2024-01-15T..."
}
🎯

2. Training Cutoff Metadata

Every proof includes "existed before" markers for major model training dates.

GPT-4✓ Before Sep 2021
Claude 3✓ Before Aug 2023
Gemini✓ Before 2023
Llama 3✓ Before Dec 2023
🔍

3. Derivative Detection

Content fingerprinting identifies when your work appears in AI-generated outputs.

• Perceptual hashing for images
• Semantic fingerprinting for text
• Audio waveform matching
• Cross-model similarity detection
📋

4. Evidence Packages

Court-ready evidence for copyright claims. Complete chain of custody documentation.

• PDF evidence bundles
• RFC 3161 timestamp certificates
• Content hash verification
• Independent verification instructions

How AI Companies Can Query

CertNode provides a verification API for AI companies to check training consent

AI Company Query

GET /api/v1/training-provenance/check
?hash=sha256:abc123...

CertNode Response

{
"found": true,
"registration_date": "2024-01-15",
