    Disappearing Digital Signatures

    onesteel

      Our drafting group creates multi page sketches, each being a separate PDF file.

       

      Each page (PDF) is inserted in to a single PDF file as a composite document.

       

      Individual pages are revised occasionally and digitally signed off.

       

      The old revision is extracted from the composite document and replaced with the revised page. (PDF)

       

      When the new revision is inserted into the composite document, the digital signature on the revised page disappears.

       

      How can I prevent the digital signature from disappearing?
