Description Roque 2017-11-15 13:49:12 UTC
Hi,
My configuration :
Intel(R) Core(TM) i5-4460 CPU @ 3.20GHz, 4 cœurs

Ubuntu Linux 16.04.2 / Kernel Linux 4.4.0-98-generic sur x86_64

Libre Office Version: 5.1.6.2
Build ID: 1:5.1.6~rc2-0ubuntu1~xenial2
Threads CPU : 4; Version de l'OS :Linux 4.4; UI Render : par défaut; 
Locale : fr-FR (fr_FR.UTF-8); Calc: group

1. Using my Ubuntu PC, when I want to export a LibreOffice document from Writer (I suppose it is the same from Calc) to pdf (File /Export pdf / Security / no modification allowed and no copy allowed), despite security paramters supposed to avoid copy/past, I am able to copy and paste the text from the pdf.

2. Using a Windows10 PC, doing the same export with the same parameters (and the same document), copy and past is not allowed in the generated pdf. It works !

Conclusion: it seems the security parameters for pdf export in LibreOffice are not active in the Linux "version" 

Best regards

This does not work in macOS 10.14.0 + LO 6.0.6.2 either. 

1. Create document
2. File > Export As > PDF
3. Security, set passwords
4. Choose no changes, no allowance of copying.
5. Export
6. Open PDF and highlight any text, command-C.
7. Open another document, command-V. The text from step 6 pastes.

Copy protection does not work at all. This is an old bug; it needs to be fixed.
