Electronic Signatures

andy.kallenbach@saberco.net
Does anyone have experience or recommendations on using an Electronic
Signature with Orbeon?

Is adding a third-party signature box for a USB signature tablet in Form
Runner and also Form Builder feasible?

Right now, we are using Topaz signature pads with Word Forms.

Andy,

We thought about different ways to implement electronic or digital
signatures in Orbeon Forms, and you can see some results of this on:

http://wiki.orbeon.com/forms/projects/electronic-digital-signature

Does the third-party USB signature tablet you have in mind provide an
API accessible through a web browser? If your goal to attach the image
of the signature to a form, as if it was done on paper and then
scanned in with PKI?

Re: Electronic Signatures

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.

The third-party usb sig. tablet I have in mind does have a java based API that is accessible through a web browser. My goal is definitely to put the image of the signature into the appropriate place on the PDF render and/or the HTML Render of the completed form.

I'm not looking to do anything with PKI, if you are talking about public key type certificates/authentication/security/etc.

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.

Wherever the signature image can be legally disputed and challenged by the customer.

But having said that .. buying a 'burger from Hardee's is a completely different risk profile than transferring funds in a financial transaction.

Re: Re: Re: Electronic Signatures

andy.kallenbach@saberco.net
Not that wikipedia is an authoritative legal source, but the link below certainly reflects my understanding that Electronic signatures, even "scanned" signatures are legally binding and hold up in court. Using a tablet that can capture some level of pressure/etc during the signing process increases its identity.

http://en.wikipedia.org/wiki/Electronic_signature

IANAL, but there is more involved in contract law than proving the identity of the signature. Intent, business relationship, phone conversations, payment, signatures all hold sway. Forgery is not a new problem. In a perfect world, we would all be running around with third-party validated certificates that we could control at will, but we are not there yet? It seems that the law recognizes this?

Re: Electronic Signatures

DL
You make the valid point that signature "features" (biometrics such as pressure) can be captured rather than just the static image. But to have an acceptable FAR / FRR (false acceptance rate / false rejection rate) there must be a number of such features .. rhythm, flow, sequence of "dotting the i's and crossing the t's" etc.   Typically about 16 features are used for discrimination.

Just reproducing a static signature image attached to a form offers a false sense of security.

What is to prevent it being captured by a sniffer and added to a form without the owner's permission?

How are disputed signatures managed?

So it is a deep subject and only really worth debating where there are significant risks such as medical privacy or financial privacy.

Here is one blog on the subject ..

Estonia (where I live) has been using PKI-based digital signatures since 2000. Today I even don't remember, when was the last time I gave "real" handwritten signature. But I use my smartcard (ID-card) every day to log in to internet banks, sign bank transactions, sign contracts with my clients, etc. During last two votings I voted electronically.

OK, I may be biased, because I'm a software developer and my main client is the developer of Estonian ID-card software. But nevertheless, I just checked, 40% of signups to one webservice our company provides, are made using ID-card.

So I suppose you can make people accept PKI-based signatures, but it requires support, both legal and promotional, from the highest level - the government.

Regarding Orbeon - we just converted Estonian state portal www.eesti.ee from Chiba to Orbeon and launching it in coming months. It contains a component, that allows you to download responses from e-services digitally signed by portal. Or download the response encrypted, so that only you with your ID-card can decrypt it. It's not tightly integrated with Orbeon, it's more like a wrapper. And it uses Estonian DigiDoc format, which I suppose is not useful in other countries.

Good point, my viewpoint is very american. Just further evidence that we don't always get the cool toys! Unfortunately, nationalized id cards and the like have always been met with stiff resistance.

Re: Re: Re: Re: Re: Electronic Signatures

Einar Moos
Andrew,

Isn't the US  DMV driver's licence - ID - considered national (or federal) proof of identity? Or the Alien Registration Card, or a biometric US Passport?

Studying today's DMV web standards makes me believe that a rational, simple application could be provided to them, too. I just look forward to the moment when digital signatures will be available on commercial browser screens where you have to press your right thumb and click "Enter".  IMHO that is the best solution, already in service at the desk on cumbersome "toys". Interestingly enough, the right thumb solution is probably the most sensible, if and when the government is ready.

Cheers
