Digital Signature and Rights Management

[Diego-Silva]

Hello all,

I'm following the document below and have a couple of questions on how to achieve that objective, that is how to provide a persistent document security.

I understand that I need to protect the PDF first using the Rights Management, then digitally sign it afterwards. This is pretty straight forward when using LC Digital Signatures, just build a process in LC Workbench, unlock the PDF temporary, send to Digital Signature operation, get it back and return the RM.

But when I use a third part digital signature solution? Is it possible to use another digital signature solution to get this - by defining a call to a webservice in workbench to sign the PDF.

For information: this digital signature solution complies with digital signatures in PDF.

Thanks in advance!

Diego, what is the 3rd party signing tool? I'm going to assume that if you apply RM to the PDF and then push it through a 3rd party solution the 3rd party solution won't be able to process the document unless they're part of an Acrobat plugin.

You may need to setup a workflow to un-RM, add the 3rd party sig, then re-RM the PDF.

Hi Lee,

It's some module within IBM Lotus Notes. I'm trying to do the following in the Workbench:

With a RM document, Unlock it then invoke this 3rd part webservice in order to sign it. It's not working so far.

But if I follow your suggestion, when I re-RM the PDF wouldn't this invalidate the Digital Signature?

Thanks for the quick reply!

I mentioned the re-RM'ing as with some of the 3rd-party apps I've seen they don't actually do real dig sigs. I don't have any experience in recent years with Notes implementations but history would say that RM'ed documents would not be supported.
