Technical details

Exactly what’s in a Vouch.

How it’s sealed, what it records, how to check it yourself — and what it doesn’t claim.

The seal

Sealed by our server, not your phone.

  • 01

    The time is ours

    The time on a Vouch is our server’s clock at the moment it’s sealed. The phone’s clock is never used.

    Filmed with no signal? The time is when it seals, not when you filmed.

  • 02

    The ID is made at the seal

    Every Vouch gets an 8-character ID the moment it’s sealed, like 2TED-QDRH.

    IDs never use O, 0, I, L or 1, so they’re easy to read out loud.

  • 03

    Then it’s locked

    Once it’s sealed, nobody outside Vouchover can change the photos, videos, name or time. The database has no door for it.

    Inside Vouchover, nothing in our code changes a sealed Vouch’s photos, videos, name or time.

    Nothing deletes a sealed Vouch. There is no delete — not in the database, not in the app.

Fingerprints

Every file has a fingerprint. Anyone can check it.

When a Vouch seals, our server reads every photo and video and makes a SHA-256 fingerprint of it. The fingerprint is stored on the sealed record, shown on the Check a Vouch page, and listed on the paper.

Change one pixel of a file and its fingerprint comes out different. So anyone holding the file can check it’s the one that was sealed.

Every Vouch sealed since September 24, 2026.

IT SHOWS
the file is the same one that was sealed.
IT DOESN’T SHOW
who filmed it, or that they own the thing.
CHECK A FILE YOURSELF
# 1. Save the photo or video from the Vouch
# 2. Get its fingerprint — Mac or Linux
$ shasum -a 256 identifier.jpg
# — or Windows
> certutil -hashfile identifier.jpg SHA256
# 3. Compare it with the fingerprint shown for that file on the Check a Vouch page

A fingerprint, not a signature. It’s tamper-evident: a changed file shows.

Or let the site do it: on any Vouch sealed since September 24, 2026, open Check a Vouch, type the ID, pick the file you saved, and the page names the piece it matches. Nothing is uploaded.

On the record

What a Vouch shows. What it keeps to itself.

Shown to anyone with the link

  • The ID and the seal time (our server’s clock).
  • The item’s name and who made it: their name, and their company if they gave one.
  • The place, in words, like Calgary, AB, with one quiet word saying how it got there: GPS, GPS, edited or typed in.
  • Every photo and video, each with its fingerprint.
  • What was said in each video, written out. The recording is the record; the words are a copy you can check against it.

Kept on our server, never shown

  • The exact GPS spot. It’s stored on the sealed record and never goes on the page, the paper or the link.
  • Your email. It’s how you sign in, not part of a Vouch.

GPS says where the phone was. The word next to the place says whether a person changed it.

Open, and on paper

The ID is open. The paper points back to it.

The open ID

  • Any sealed Vouch opens from its link or its ID. No account, no app, no expiry.
  • Typed a letter wrong? The ID box offers the close match. It never guesses for you.
  • IDs never use O, 0, I, L or 1.

Try it: type TUSF-3UDV.

The paper

  • Every Vouch prints as a report, with what was said in each video.
  • Every page carries the ID and the address of the live record.
  • The paper is a copy. The live record is the real one. If they ever differ, the live one wins.

The limits

What we don’t claim.

A record is only worth what it honestly says. So here’s what a Vouch is not.

  • Not signed or certified

    Files are fingerprinted, not signed. Nobody certifies a Vouch.

  • Not tamper-proof

    It’s tamper-evident: a changed file shows. That isn’t the same as impossible to change.

  • No blockchain

    The record lives in our database, locked after the seal.

  • Not proof of who, or who owns it

    A Vouch shows a thing at a moment. It doesn’t check the person or the paperwork.

  • Not an inspection

    It shows what the camera saw. It isn’t a mechanic’s report.

  • Not a “verified location”

    GPS says where the phone was. If a person changed the place, the page says so.

  • Not proof the phone wasn’t tampered with

    The app can only film live. A Vouch can’t prove the phone itself wasn’t changed, or that nobody filmed a screen.

WHAT WE DO SAYReal photos and video, taken live in the app, sealed with our server’s time, fingerprinted, and locked against change from outside.
