Protect the documento

i would like to protect a presentation made with index.
The best you can do is to make Save as and set a password for the modifications and maybe leave blank for the opening.

But i saw that yes, you cant modify, but you can easily quietly select all the words and copy them, select every image and save them, export the file to pdf (and if you have a pdf editor change it). Yoy can easily copy all the text boxes with everything inside and copy all with a simple ctrl c + ctrl +v in another empty document and do everything you want.

So a complete useless protection Really displease that.

Not possible to choose a better protection for the document?

If do you want to protect it, don’t share it.

Also can convert each slide in a unique image, to not allow copying text.

Or export as PDF with password, not permitting printing and disabling copying of content.

And may be there are other options.
