Trust & security

A verdict you can check.
Not one you must believe.

Verifact is designed so that its own honesty is not a requirement. The standards are open, the keys are in hardware we never touch, and the timestamps come from a third party.

01Foundations

Four properties every proof stands on.

C2PA
Provenance format
The open Coalition for Content Provenance and Authenticity standard. The proof lives inside the file and any conforming tool can read it.
Ed25519
Signatures
Modern elliptic-curve signatures over every byte of the image and its capture facts. One changed bit, one failed verification.
RFC 3161
Timestamps
An independent timestamp authority countersigns each proof, so capture time does not rest on the device clock or on our word.
Android Key Attestation
Device identity
Signing keys are generated inside the phone's secure hardware and attested by the platform. They cannot be exported, cloned, or simulated.
02Key custody

We cannot sign a photo for you.

Capture keys are created inside each phone's secure element and never leave it. Verifact has no copy, no backdoor, and no way to fabricate a valid capture — and neither does anyone who breaches us. A signature exists only if that device sealed that photo.

03Honest failure

Red results are a feature.

A verifier that always says yes is worthless. Verifact reports exactly three states, and never rounds up:

Verified
Proof checks out
Every link in the chain re-computed and held.
Failed
Proof broken
The file was altered after sealing. The verdict names the broken link.
Unverifiable
No proof present
The file carries no Verifact manifest. That is reported plainly — never as genuine.
04Privacy

Verification is not surveillance.

The verifier examines a file only to check its proof. The public certificate verifier confirms a certificate's signature and returns signature metadata only, never claim details. What we collect and why is written down in plain language in our privacy policy.
