How to provide access to a pdf file washer without the possibility of downloading?

Question

Access rights

The task is to provide access to a file storage facility with documents in pdf, access is needed only for viewing, without the possibility of downloading to your computer, printing.

Now implemented through crutches: terminal server, remote app adobe acrobat. The user connects via RDP under his account, his buffer, printers and disks are cut off. The solution is so-so, as the company grows, more and more people connect.

Microsoft Sherpoint, like Google Docs, has functionality - without the possibility of downloading only for individual documents, not entirely for a folder.

Solutions with virtual data rooms are considered. Space prices.

Are there alternative solutions?

Answer 1

Try to formulate what problem you are solving in this way. And how should the screenshots saved by the user of what he was given to see differ from those PDFs that he was forbidden to download.
For example, you can create a repository of the same PDF, automatically compressed to screen quality. But if there are not pictures inside, but a vector (and font) - you will have to try to spoil it.

Answer 2

With this implementation, we solve some paranoia of the leadership - they are afraid of a leak. In the archive, as I said above, large drawings are stored, screenshots can be turned off.
