Sure, I understand this from a theoretical standpoint, but are businesses really concerned about having an air-tight signature?

Quite a number of places have paperless scanning systems with all kinds of forms like contracts, employee info, government forms, etc. They all have analog signatures that are effectively reduced into a digitized format and are probably easily forged. Why not use something like Orbeon where you could use your own forms on a web server and sign with a pad?

Using PKI, cards, and other mechanisms seem to have a collective ?huh? from most business managers. They are not easy to implement or understood by both potential users (employees and customers).

Is there a particular vertical market where scanned signatures don't work?

I have a Hardee's franchise that I am pitching this project to right now so they can remotely get paperwork filled out at 30 different stores along with a signature pad because that is what they are comfortable with. I envision bringing up PKI, cryptography and the like would make their head spin. Unless there is some tech out there I am not familiar with that maintains users comfort with their signature with our tech desire to maintain the absolute.

The problem with the solutions proposed above is that images of attached
digitised (analogue) signatures can easily be forged.

Some long time ago I worked on dynamic signature verification  .. i.e.
biometrics.
But dynamic signature verification (using signature capture pads) is not
really practical or secure in an internet environment.

Today I would look at http://www.bouncycastle.org .. java api .. and
integrate digital crypto signatures (not analogue signatures) into orbeon
server.
