            Bug ID: 438671
           Summary: Feature request: Activating of Adobe DRM with okular
           Product: okular
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Severity: task
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: michael.kasimir at gmx.de
  Target Milestone: ---

Subject: Okular in connection with DRM.

In connection with the provision of non-public documents, which are 
provided in a a secure data room okular does not work. 
A data management system that is apparently created by Brainloop AG.

Opening of *.pdf files only works with Adobe Reader, because the
Adobe rights management is activated in the Secure Data Space and a user can 
therefore the user will always see a Brainmark file as a PDF file.
A Brainmark file is the copy of the original file as an image or PDF,
which is watermarked.

This works apparently only in IOS and Win environments.

After logging into this online "Secure Data Space" , it is not possible to open
the 
documents with Okular. 
There follows a pop-up window that asks for a password that the user not has.

If this file has been saved locally and the connection to the "Secure Data  
Room" is offline, the document cannot be opened.

In my opinion, this does not exactly promote digital sovereignty away from 
mainstream software components such as Adobe Reader with all its security 
problems.

Is there a DRM module EXISTING or PLANNED for Okular?
