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.
