A phone reading a stamp mark on a specimen document
Use case: Scan and retrieve

A printed mark that opens the record, for the right person.

The document stays in the registry. Its fifteen characters are printed as a scan mark on the paper. A phone reads the mark and, with the grant, its secure element and the owner's passkey, regenerates the document.

Scan and retrieve

Paper that points, rather than paper that holds.

Deeds, records, certificates and IDs are copied, posted and lost. Here the paper carries a pointer, not the document. Copying the paper copies a pointer that opens nothing on its own.

When the paper stops being the copy

Today
  • The paper is the document: lose it and it is gone.
  • A photocopy passes for the original.
  • No record of who opened what, or when.
With the engine
  • The paper points; the registry keeps the document.
  • A photocopy points too, and opens nothing on its own.
  • Every opening is logged; a withdrawn grant opens nothing.
How it works

Watch a deed go from the registry to a phone.

The mark's design, the four steps, then the record pinned to the paper in augmented reality. Scroll inside the demo or press Play; turn on CC for the narration.

  1. 01Implosion

    The document is fingerprinted and folded into one root, named by fifteen characters.

  2. 02Transmission

    Only the fifteen characters are printed, as a scan mark on the paper copy.

  3. 03Regeneration

    Five checks: the mark, the cell, the grant, the phone's secure element and the owner's passkey or face. The document is rebuilt on the phone, bit-exact, and pinned to the page.

Demo with illustrative documents and values. Element counts and capacity per design are to confirm.

A bank archive of steel drawers, one glowing
In practice

A title deed, checked at the counter.

  1. 01First

    The registry implodes the deed and prints its mark on the owner's copy.

  2. 02Then

    At the bank, the owner scans the mark with their phone.

  3. 03Finally

    The grant, the phone and the owner's passkey are checked. The deed opens, and the opening is logged.

Example scenario, not a customer deployment.

What holds, every time

A pointer, not a secret

The mark names the document. It opens nothing by itself.

Five checks

The mark, the cell, the grant, the phone's secure element and the owner's passkey or face.

Every opening logged

The registry can withdraw a grant at any time; the same mark then opens nothing.

Questions about scan and retrieve

Draft answers. To confirm with product and engineering.

What if someone photographs the mark?

They have a pointer. Opening still needs the cell, a grant, a phone with the right secure element and the owner's passkey.

Does the mark need special printing?

[Print requirements: to confirm with the AR engine's design rules.]

Can the record change after printing?

[Versioning of the document behind a printed mark: to confirm with product.]
