the one benefit i see is as a final “lock in your answer” function for any form you’re submitting.

And did they have to stop allowing written signatures because of AI scraping? Or is it just because they never looked legible at all?

    The point of the signature isn’t the mark, but that the affirmation on the document can reasonably be tied to you. For most of history, it has been tied to a certain mark, whether it be a signed name, a stamp or embossed seal, or even a drawing. That system generally breaks down in the digital age.

    A low hanging fruit that is seen to work is having the mark of approval get tied to an account under the control of the signee. It isn’t so much that you made the mark but that it is tied to an email address you control. So even if you don’t sign it with an actual signature, it still gets tied to you.

    Signature matching/analysis isn’t particularly scientific, so in general a physical signature is used for clear authorization, not identification. When you log in to something to sign your identity is already set by other means, so all the signature needs to do is say “yes, I agree to this”. E signatures in the US were legally formalized awhile ago, so it’s not really a controversy.

    I think a digital signature is also a way they can prosecute for impersonating someone for identity theft. By you typing and saying “this is me” if it’s not, they can use that as evidence.

    The visual signature part of a “digital signature” is purely cosmetic. The actual signature is the entire file being cryptographically signed using a private key you possess, which any recipient can then verify came from you by using a public key.

    This is the case for all government issue signatures (like when using the private key inside a chipped government id card) or any other signature created using a key pair from an issuing authority.

    If its not a digital signature in this way, the other way is literally just an image. It can be a vector or an raster, or a straight up scan of a physically signed document. It’s just a picture. It has no digital verification whatsoever.

      Surely they’re talking about the likes of DocuSign, which doesn’t involve any user-controlled keys

      • That didn’t quite explain everything. I want to add that there are “type your name to sign” forms that are just what you described, just bytes spelling out your name. In those cases, you’re right, those bytes don’t have your handwriting to prove anything, but they do accomplish something. If the form is secured behind a login and not a totally buggy heap of garbage, then the act of typing your name on that form demonstrates that whoever logged in deliberately expressed their approval. And whatever level of identity verification is needed for login is then playing the part of demonstrating who did that. That’s not perfect, but the level of evidence might match the level of risk enough to justify that mechanism to the company providing it, and it’s important to consider all factors: not just system cost, but end user tolerance.

        E.g., there was (maybe still is?) a “ham” radio logging system that had end users generate their own PGP signing key pair to sign their log books, which are simply a list of who they talked to over the radio, always for non-commercial purposes (by law). Many questioned whether a secure web site with good 2FA might suffice and be much more convenient, manageable, and adequate risk level for most users.

        “Digital signature” is a proper term that should mean what the parent comment explained–public key crypto “signing” (a hash of) a document’s content–but “sign here by typing your name” will inevitably get called a signature and, obviously, is also digital, just not a real “digital signature”.

      the other way is literally just an image (of your signature)

        How is it legally murky? Someone asks if that’s your signature on the document and do you remember signing it, and it is and you do, so you say yes. End of discussion.

        It’s only a problem if you’re claiming it’s not your signature. But then, they have to prove it’s your signature, you don’t have to prove it’s not. I’m not sure you can prove it’s not your signature, hence burden of proof being on the other party.

      No I disagree, the idea with physical signatures is that you write it in cursive, so in theory nobody will do ot exactly the same way as you write it - but then people can forge things, and since people don’t actually write their name the exact same way every time, forgery is essentially as good as perfect.

      Edit to fix typo and add italics.

        In parts of the world, paperwork is managed with stamps and a mark. Your doctor in latin america will stamp a blank prescription pad with a stamp that has their name and license number. They will then make a recognizable mark over the stamp. Same with your lawyer and all government offices. The point isn’t that someone can use handwriting analysis - which is just fluff - and rather that they possess the stamp and those who would read the paperwork recognize their particular mark.

        Nobody has relied only on signatures to verify that a person signed it, since forever. Especially because forgery was always a thing.

        This is why documents that are important aren’t just signed by one person; they’re signed by witnesses who presumably will vouch for it. (Like notary public’s are a thing.)

        For lesser contracts they first verify you are in fact you.

        There’s no functional difference online- to within a reasonable standard.

        Signatures have never required cursive. Historically, people who couldn’t read or write would just put an X in the signature spot and that was valid. Yeah, there is a marginal benefit to physically signing something in cursive, but the purpose of signing it has always been more of a final agreement step.

        If handwriting and spelling and how I signed it actually mattered at all legally, then I could sign a different name when I buy a car, get keys, drive away, and later in court, say “well I never agreed to pay for this car, look at my signature, it says Frank Sinatra”. Same goes for a true forgery. The evidence I didn’t sign it myself is my statement in court saying “I didn’t sign this”, and whatever signs there are that I didn’t benefit from this.

          Where I come from the X thing wouldn’t be legally binding. What people who couldn’t read or write would do is using their fingerprints. They would put their finger on a stamp ink pad and then stamp the paper with their finger. That’s why we say “someone who uses their fingerprint” as a euphemism for “illiterate”.

            That’s really interesting and a great way to do that, honestly. A singular fingerprint also makes more sense than needing handwriting analysis to detect a forgery, too. Kinda feel that should be the norm everywhere, honestly, a signing and a print next to it to verify against if the need arises.

          So your last paragraph is a bit off. One it was generally checked with your id that the names were the same. I often had to sign a non typical signature because of a place that required the full name. then also signing someone elses name on a document would be something they can go after you for. Im not sure which all laws but you can’t pretend to be someone you are not with contracts and agreements and such.

            I was still speaking historically, so I meant before easy checks like your ID were in place. Its definitely harder to do that, nowadays. But of course they can go after you for it, that’s my point. You’ve agreed to a contract by the act of signing anything. If I forge a name of a nonexistent person, they can still go after me as if I’d signed it normally, because the act of signing at all is what binds me, not what I actually sign. I held the pen, I agreed to the contract. It would be ridiculous to escape legal consequences by doing things like signing differently, and in this area of law, at least in the US, common sense prevailed and I’ll be liable for whatever I willingly signed, whether that’s my name, an X, a fingerprint, a fake name, or anything else.

            Does writing your words with extra loopy bits that are less legible than print REALLY make you a better person?

            Not learning cursive is like not learning Latin. Maybe it was useful at some point, but the only reason to push for it now, is because “That’s how I did it, so it must be the best way, and everyone else is wrong!”

              On the flip side, there’s validity in doing things just for the aesthetics of it and we sacrifice too much to the ever present drive for efficiency.

              Cursive isn’t necessarily the banner we should all rally behind for that though handwriting something is still shown as one of the best ways to remember something.

              As a fan of fountain pens and handwritten letters it is nice to get one knowing someone put that effort into it.

              I dunno where I’m going with any of this. Teachers and schools are underfunded, if kids are fucked it’s our fault don’t blame them, fancy squiggles are fun.

              I think there’s validity in learning/teaching cursive, if you’re proficient it’s a much faster way of writing. Handwritten notetaking has been shown to be more effective than digital in terms of concept retention (you’re not just regurgitating content verbatim), and cursive can facilitate better notetaking. I’d argue its setting students up for better outcomes in secondary and post-secondary institutions.

              Regardless of that I do agree with your view, we should not just continue things for the sake of tradition, young people aren’t “terrible” for forsaking certain traditions. If anything, re-evaluating what we hold as important is a useful exercise, especially when it comes to education.

                Reading through these comments and I’m just now realizing something; I’ve never gone searching to see data on if cursive actually is faster on average and if so, how much. And does that handwriting improves memory fact apply more to cursive or print writing or equally just because it uses more muscles in general?

                I’d imagine it would partially depend on the script chosen, ligature vs looped, Spencerian vs New American vs D’nealian etc for speed but the memory thing I’ve got no guess.

                To put a finer point on it, it’s not even just “moral fibre”. Sure, higher societal morality is something we should all strive for, but I’m not even asking for that much.

                It’s the morally neutral bullshit like handwriting, or reading a novel on your phone instead of on paper, or spending your free time playing video games or watching YouTube/Twitch as opposed to watching Network television. There’s no reason to raise a fuss or dub others inferior for doing things a little different.

    Digital signatures are much more than “just typing your name in a box”. The few times I digitally signed a doc I didn’t even have to do that, just click on a big green button.

    It’s all connected to how you authenticated before you got to that point.

    I think that’s probably it, or pure cargo cult because “we’ve always had signatures so something’s got to go in that slot”. The whole idea of random scrawls for “authentication” has been weird all along. As if everyone walked around knowing what everyone’s signatures should look like. And if you do know, you can just… write it that way.

    (Plenty of countries just have digital “signing” that’s a bit more like something sane, a central authentication thing based on your ID number and 2FA.)

    It does as much as does “testifying under oath” does to magically stop you from lying.

      Let me try and rack my brain for everything I’ve digitally signed

      • recruitment/employment agency (about 2-5 different ones i think)
      • medical stuff? Definitely for private medical care like dentist and foot doc, whereas NHS can just ask for DOB and NHS number.
      • online registration at uni maybe

      It’s not that they’re not allowing written signatures but that they’ve removed them from everything because it’s all done online - they have no space to try and write one with your mouse or your finger, like usual.

      If you show up in person they get one on a tablet, though, usually.
