Kind of tangential, but I'll share a bit of a horror story from a friend when it comes to e-signatures. The company in question uses DocuSign, and most of their clients do as well. They are big, serious companies. However, nobody is able to set up DocuSign in a reasonable way for a multi-client contract. Every company needs to use their own DocuSign. Now, DocuSign embeds a cryptographic signature in the signed PDF. T…
Like, on paper, you are supposed to all "sign" the same paper document to show that this is the same document/content that is agreed by everyone. And so, when you DocuSign it, people do the same thing with everyone signing the same document even with a fake "handwritten" signature....
But if you really think about it, the signature already proves the content, so you would only have to have all the parties sign individually their own "copy" and then exchange the signed pdf signed by them. If you own a copy signed by you, and a copy signed by another person, as we have the proof of the content of each one, you know that it is the same contract that was agreed...
