RE: Verifiable Credential Notarization and Third-Party Notary Services Providers: User Scenarios

RE: but I would be uncomfortable as a notary notarizing that a person's Blood Pressure was 120/80 or any other number as it is dependent on the accuracy of the device and the skill of the individual using it

John, that' not the point ...my apologies if my example was too specific.

Alice simply has 2 numbers to report. ...2 metrics Alice wants to send to Dr. Bob ...where there exists an existing trusted relationship as a patient of the doctor and doctor to the patient.

Scenario A could, alternatively, be recast as Alice wanting to send an Appointment Confirmation to Dr. Bob's Clinic ...instead of a blood pressure reading.

This is important feedback.

Thank you,
Michael

p.s. When a public notary witnesses your signature on a passport application, for example, they're simply attesting to the fact they saw you sign the passport application (and perhaps your address information) ...not that any of the information provided by you is correct.

Not sure of all the background discussion on this, but I would be uncomfortable as a notary notarizing that a person's Blood Pressure was 120/80 or any other number as it is dependent on the accuracy of the device and the skill of the individual using it

In scenario A, Alice wants to report an actual blood pressure reading to Dr. Bob's Clinic. ...something like "120/80" ... really the pair of individual numbers. Alice wants the reading to be signed by her and notarized by SOVRONA as trusted notary ...that is, SOVRONA acts as a witness to Alice's signature of her own self-issued blood pressure home reading.
Wrt to your question about scenario B, the Sovronia driver's license should appear to be signed by the Province of Sovronia whose signature is witnessed by SOVRONA, the mutually trusted credential notary.
A and B are actually different examples of the same more generic credential notarization scenario/problem.

Hi Michael

can you please explain these scenarios a bit more for me.

A. The user creates any blood pressure reading they like, true or false, and gets a notary to certify this? Is this what you intended?

B. What is the difference between a Sovronia DL signed with Sovronia's key or with Soveronia's notariser's key if the verifier knows and trusts the right public key?

Kind regards

David

I believe there are a large number of scenarios where individual Persons as well as Organizations are going to want to (self) issue Verifiable Credentials using the credential notarization services of a third-party notary service provider.

Here's 2 user scenarios as examples:



  *   User Scenario A:  (steps A1...A8)
Alice self-issues a blood pressure home reading (BPHR) credential to Dr. Bob's Clinic using SOVRONA's credential notarization services. SOVRONA is a third-party notary services provider/network.
  *   User Scenario B: (steps B1...B8)
The Province of Sovronia issues a Sovronia Driver's License to Alice using SOVRONA's credential notarization services. SOVRONA is a third-party notary services provider/network.



I have a some drill-down questions (e.g. protocol detail questions) but first, let me ask what general questions/comments have about the validity of the  2 user scenarios depicted below.
