We protect our Documents with copy and Print Protection.
Now we upload the documents on our Server to look at them on our Homepage.
Now if I open the PDF via Browser the Copy Protection is gone and i can copy what i want.
I think it is a matter of the Browser Plugin, which ignores the Protection.
Do you have a clue for me?
You are correct. This is why Acrobat warns that third party apps may not respect permissions. It is a pity, and you may report it to the browser makers.
