Is there a way that I can see who has modified a PDF document and when like it is possible on a Word, Excel, etc. document.
As an exemple, I would like to be able to know who signed my document, because I want to make sure that it's truly my manager and not his administrative assistant because she have is digital signature.
P.S. I'm french, so please excuse my bad grammar !
