(HBO) Silicon Valley Reference: That looks like the Gavin Belson signature.

This is kind of useful though, I was in shock and horror when I realized one PDF my Adobe Fill & Sign app couldnt... fill and sign, an actual IRS tax form. I don't know why they let you fill most of it out but force you to sign the damn thing. What's even more confusing is other forms don't restrict this, it's just one of the ones I tried (can't remember which one but it was a while ago).

I don't get the magical power of a signature at all. Everybody can write my name under a document. This project basically allows you to forge your own signature. Is it still legally binding? Do these rules even remember the original intent?

It can be used to claim that I didn't sign it either.

Unless it's a master forger. I could look at the document and figure out that the signature wasn't mine.

It's not a false signature, this kind of thing is standard practice for digitally signing documents. DocuSign even allows you to insert a computer-generated signature that looks nothing like your "real" one. What matters is the audit trail. This is legally binding the same way clicking the "Buy" button on Amazon is.

Can I have your phone number, I need you to explain this to my HR department and to the HR department at my last job and of my roofing contractor and dozens of other people who demand wet ink signatures.

Earlier quoted context omitted.

In a way I don't think it's possible to forge one's own signature. What's the diference of my signature from the forgery of the signature I did myself? Signature on a piece of paper says "I read this and agree with what's written so I've put a unique piece of ink there to show my agreement" doesn't really matter what you put there if all parts agree on its validity.

But what if you aren't the one who forged your own signature? How are you going to prove that someone else scribbled something on a PDF?

The forging of a signature has always been a possibility, which is why witnesses are required for the important stuff.

On the other hand, you would be right in thinking that there is a somewhat anachronistic element of theater in having signatures on electronic documents.

The act of marking the sig field shows your intent to bind to the contract. You can digitally sign but there are a couple extra steps to confirm the intent and identity that aren't hard but are just hard enough to make DocuSign a lot of money and leave everybody else to print/sign/scan their stuff.

So you're saying the signature itself is irrelevant? It's just an elaborate checkbox? The question then is how do you prove I was the guy who checked the box?

It’s sort of is actually. What really matters is the providence of the approval, the adult trail or whatever you want to call it. You are creating a record of when and that you agreed to something and the signature is an artifact of that agreement.

A signature is somewhat harder to take them and checking a checkbox and can be somewhat more easily traced back to the signatory, so it’s probably somewhat better than a checkbox.

Mac’s pdf viewer Preview has a signature capture feature built in that’s pretty slick. I use it all the time and haven’t encountered an objection. Tbh I’d wonder why you need to fuzz up and fake scan the image. If someone’s requiring that the doc be “signed in ink” or some such, more power to you!

From the link: "For bureaucratic reasons, a colleague of mine had to print, sign, scan and send by email a high number of pages. To save trees, ink, time, and to stick it to the bureaucrats, I wrote this script." So yes, it does seem like there are situations where a "digital" signature is insufficient.

My bank sometimes requires a “wet” signature and have rejected digitally signed PDFs from MacOS Preview before. This tool will come in handy.

I love the idea. Is there any way to programmatically distort a digital signature so that I can avoid printing the signature pdf too?

that would be forgery, i’ll say

If it's your own signature, by definition it cannot be a forgery.

Every bank application I've done has required print + sign + scanned, I got refused when I tried sending them PDFs signed in Preview/Acrobat
