🎨 Content Certification • Provenance Verification + Receipt Graph

Content Certification

Prove what's real instead of trying to detect what's fake. Cryptographic provenance for every piece of content.

The Content Trust Crisis

Deepfakes, AI-generated content, and stolen work make it impossible to know what's real.

🤖

AI-Generated Flood

90% of online content will be AI-generated by 2026. How do you prove yours is authentic?

🎭

Deepfake Explosion

Deepfake videos up 900% in 2024. Reputation destruction in seconds, recovery takes years.

⚖️

Copyright Theft

Creators lose $billions to stolen content. No proof of provenance = no legal recourse.

How CertNode Solves It

Three layers of protection: Provenance Verification + Legal Timestamps + Receipt Graph

1

Provenance Verification

Don't try to detect AI content. Prove what's real instead with cryptographic chain of custody.

  • C2PA content credentials (Adobe, Microsoft compatible)
  • Content registry with ownership proof
  • Cryptographic chain of custody from creation to publication
  • Batch processing (10K items/hour)
2

Legal Timestamps

RFC 3161 timestamps provide legally binding proof that content existed at a specific time.

  • Legally recognized evidence
  • Independent timestamp authority
  • Tamper-evident signatures
  • ES256 cryptographic proof
3

Receipt Graph

Link content receipts to transactions and operations for complete provenance chains.

  • Content → Payment → Access logs
  • Complete provenance tracking
  • Trust score calculation (0-100)
  • Interactive graph visualization

Who Uses Content Certification

📰

Newsrooms & Journalists

Verify source credibility, establish provenance for media, and prove photojournalism authenticity.

Example: Reuters

"Photo submitted by citizen journalist → C2PA provenance check → RFC 3161 timestamp → Published with verification badge"

Pricing: $29/mo (Starter plan, 500 credits)

🎨

Creators & Artists

Prove you created original work, protect against theft, and monetize authenticity.

Example: Digital Artist

"Upload artwork → Certified timestamp → Someone steals it → You have cryptographic proof you created it first → Win copyright case"

Pricing: $29/mo (Starter, 500 credits)

🏢

Content Platforms

Verify user content at scale, require provenance for uploads, and build trust with verified creators.

Example: Social Platform

"1M user uploads → Provenance check → Verified creators get badges → Unverified content labeled → Trust built at scale"

Pricing: $499/mo (Business plan, 25,000 credits)

🔐

Enterprise & Legal

Legally timestamped evidence, forensic analysis, and compliance documentation.

Example: Insurance

"Claim photo → Provenance verification (no chain of custody) → Flag for review → Save $50K → Provide cryptographic proof in court"

Pricing: Custom (Enterprise tier, white-label)

How It Works

3 steps to certified content

1

Upload Content

Upload images, videos, or documents. We compute a SHA-256 hash and check for duplicates.

$ curl -X POST https://api.certnode.io/content/certify \
  -F "file=@photo.jpg" \
  -H "Authorization: Bearer sk_live_..."

→ Receipt ID: rct_abc123xyz
2

Verify Provenance

Attach C2PA content credentials and register in the content registry. Establish verifiable chain of custody.

$ curl -X POST https://api.certnode.io/v1/c2pa/sign \
  -d '{"content_id":"rct_abc123xyz"}'

→ C2PA Manifest: Attached
→ Provenance: VERIFIED
3
