How does your notary service qualify or certify an individual signatory, such as with a photograph AND signature on a government-issued identification?
Have a look at the BITNATION ID, there is a photo, height, name etc. And of course the signature key, linking all these together since the keys are generated with the ID and signs the content. It is the keys and the signature on the notary solution that makes the ”digital signature” valid. It is an ”advanced electronic signature” in line with EU law. (not tested in court, but it is pretty self explanatory in the below text from directive n.93/1999 )
advanced electronic signature: "means an electronic signature which meets the following requirements:[a] it is uniquely linked to the signatory;[b] it is capable of identifying the signatory;[c] it is created using means that the signatory can maintain under his sole control; and[d] it is linked to the data to which it relates that any subsequent change of the data is detectable" (art. 2.2 dir.).
How does your notary service verify whether that signatory is alive, or mentally-competent having the ability to discern document intent and meaning?
How does someone do this when any digital keys are used? Or any non-face to face verification, or even face to face by the way since there have in fact been numerous cases of fraud with all forms of IDs, digital and analogue. This is a question closer to metaphysics really. Mathematically and statistically, most people want to be honest and prove they are themselves, but of course there may be crooks. They can always force someone with violence, to go use their own valid ID and face to do stuff they do not want to, like sign deals, withdraw cash etc. It is the system that is flawed and not the ID.
What the notary does is: prove that the document in said form exists at a certain time, and proves that it is signed by the digital keys belonging to the Bitnation ID of the holder. We can of course never prove ”who enters the key and the password”, but we believe it is the person.
same sort of security. Also - the fact that a ”use once” keypair can be generated is for the document to be timestamped. and also possible to verify offline, with the key, so even if it is not a ”bitnation ID” keypair, it can still be verified both offline and online.
