Anchored on Polygon · tamper-evident lineage

Prove your photo
or video is real.

In a world flooded with AI-generated fakes, CertifiedCapture cryptographically locks every raw shot — and every edit — to a public, immutable timeline. So when it matters, you can prove what's real.

How a certified capture works

Three steps, all happening in seconds.

1

Captured in-app, hardware-signed

The mobile app captures directly from the camera sensor — no gallery imports. Each frame is signed with a key bound to the phone’s Secure Enclave, proving it came from a real, unrooted device.

2

Anchored to Polygon

A SHA-256 hash of your media plus its metadata is written to the Polygon blockchain in a public transaction. The original bytes never leave your device unless you choose to share.

3

Edits stay traceable

Every crop, color adjustment, or trim becomes a new on-chain entry that points back to its parent. Anyone can walk the chain and see the full edit history — no ambiguity, no silent tampering.

Why it matters

  • Insurance claims — prove damage was real, dated, and at the claimed location.
  • Journalism & field reporting — defend against accusations of staged or AI-generated footage.
  • Real estate & inspection — certified before-and-after evidence with verifiable timestamps.
  • Legal evidence — tamper-evident custody chain accepted in many jurisdictions.
