Prove It's Real

AI can generate images, video, and audio indistinguishable from reality. Detection algorithms are losing the arms race—they improve, but generative models improve faster. The solution isn't detecting fakes. It's proving authenticity at the source.

Detection is Losing

  • AI-generated content is already indistinguishable from real
  • Detection models have high false positive rates
  • Every detector can be fooled by the next generation
  • Trust in all media is eroding rapidly

Provenance Wins

  • Authenticity proven cryptographically, not guessed
  • Signed before manipulation is possible
  • Immutable chain of custody from source to consumer
  • Works regardless of how good AI becomes

How Content Provenance Works

A simple process that creates unforgeable proof of authenticity.

1

Sign at Capture

Content is cryptographically signed the moment it's created—before any opportunity for manipulation exists.

2

Anchor to Blockchain

The signature and content hash are recorded on an immutable ledger with a provable timestamp.

3

Track Chain of Custody

Every edit, transfer, and transformation is recorded, creating verifiable provenance from source to consumer.

4

Verify Anywhere

Anyone can check authenticity against the blockchain record—no AI detector required, no false positives.

Industry Applications

Journalism & Media

Newsrooms authenticate photos and video at capture. Readers verify sources directly, rebuilding trust in an era of synthetic media.

Insurance & Legal

Claims evidence, accident documentation, and legal exhibits with court-ready chain of custody. No disputes over authenticity.

Healthcare

Medical imaging signed at the scanner. X-rays, MRIs, and diagnostic images verified as genuine before treatment decisions.

Art & Collectibles

Digital art and collectibles with immutable provenance. Buyers verify authenticity, artists prove originality.

Built on Open Standards

Our approach aligns with the Content Authenticity Initiative (C2PA) standards developed by Adobe, Microsoft, Intel, and others. We build on blockchain infrastructure to provide decentralized, permissionless verification that doesn't depend on any single authority.

Stop Detecting. Start Proving.

Whether you're protecting journalism, authenticating evidence, or building trust in digital assets—content provenance is the infrastructure you need.
