I'm trying to figure out how notaries public in the USA could use Microsoft Word and the popular X.509 digital certificates to notarize a document. Lets make four assumptions about the state law:
- The notary gets to pick the technology; the state government does not restrict this.
- The notary and the signer meet in person with their computers.
- The signer and the notary each have their own digital certificate and their own computer.
- The notary is required to apply a seal after the signer has signed, and the seal is a jpeg image.
The problem is, the notary isn't allowed to add the seal image until after the signer has signed. But if the notary adds the seal image after the signer signs, Microsoft Word considers the document invalid because the addition of the image is an alteration.
