Hello Korbitec,

Sorry for the delayed response and inconvenience caused. Acrobat provides users with the capability to add a document timestamp to a PDF without also requiring an identity-based signature. A timestamp server is required to timestamp a PDF. See: Acrobat Help | Acrobat User Guide

A timestamp assures the authenticity and existence of a document at a particular time. These timestamps are compliant with the timestamp and revocation features described in Part 4 of ETSI 102 778 PDF Advanced Electronic Signatures (PAdES) standard.

For detailed information, please refer to Eliminating the Pen…One Step at a Time: PAdES PDF Advanced Electronic Signature Standard Released for EU Link: http://blogs.adobe.com/security/2009/09/eliminating_the_penone_step_at.html

Feel free to update this discussion for any further assistance.

Regards,

Anand Sri.

Hello.

I when I use "Use a certificate" and "Digitally sign" with my Qualified digital ID (EIDAS) including Timestamp - both issued by qualified authority as the second person, who signes the document (the documents already contains a digital ID), there appears a notice Miscellaneous change(s) near the first signature.

 

Why is it, that even if I DO NOT CHANGE anything in the document, just add my digital ID, there is a notice about some Miscellaneous change(s)?

Also I cannot see, what the change is!

 

Thank you.
