Wantzel example
FaceVouch
FaceVouch is for an office that works with clients at a distance and wants to be sure it is talking to the right person. The client registers once with a short live check on a phone, confirms with the same check before the advice and when signing, and the adviser sees who did. The example is a made-up mortgage adviser; it suits notaries, landlords and anyone who signs or advises at a distance.

The check, on a phone
What it does
- The client registers at the first meeting and confirms before the advice and when signing, each time with a minute of camera: look into it, turn the head, read one sentence aloud.
- The page decides nothing. The server asks the check what came of it, and a check that did not pass signs nothing.
- The adviser's overview is a log: who, when, for which moment, the outcome. No pictures and no face data.
- A client can have everything removed, and the consent text says what is kept and for what.


The demo uses a stand-in for the face check, so nothing of your camera is judged or kept. A face check is one signal, not proof of identity in law. Build it and run it with the Wantzel compiler.
