Currently I'm using QuickPDF v 10, to digitally sign PDF documents with a certificate.

Next steps are:

Adding an image to the signature with a representation of the handwriting captured signautre. (Looking at the function reference this is easily doable)

Add custom data to the signature information such as biometric data captured during the signature process. How can this be done without breaking any previos signature validation?

Any help would be grate full.

Hi Jordi,

i think you're knowing these two articles:

http://www.debenu.com/kb/add-visual-digital-signature-to-a-pdf-programmatically/

http://www.debenu.com/kb/advanced-options-signing-pdf-files/

I don't think that actual further options are supported.

Perhaps they will be ... but i think not now ;-)

Cheers and welcome here,

Ingo

I have read that the latest version has several improvements to the handling of digital signatures, but I have not installed or tried this yet. See http://www.debenu.com/blog/debenu-quick-pdf-library-12-12-released.html

but this has nothing to do with implementing additional biometric data to the signature...

I tried that and it works great!

But I need to show de signature image on all pages of the documment. There is a way do do this?
