In this moment in time, the only valid method for business documents are the real handwritten. You realize that: if you paste something on an ordinary paper, how can you check the currency of this, or how can you prevent the multiplication of this signature? What you want it's possible but only on special paper (for money e.g.). Of course, you can use a pasted handwritten on ordinary paper but you will have big problems to prove the identity of this.

On business documents (those that still live in the paper world) where public/private keys and signature verification are unavailable, is there a way to make an electronic signature (a handwritten one that has been scanned in) more secure? Possibly by watermarking? Anyone can scan in a handwritten signature and paste it into a document, but I'm curious about how one might watermark or otherwise secure it. Thanks! Mark
