manager how many readers can read a secured PDF ?

[Admin E-Labor]

Hi,

Summary : I want to limit the number of readers of a book published in PDF, to avoir the users could copy our book content with no payment. 

Scenario : 1 (paying) reader could read our book on line with his cloud account, but could not donwload the PDF itself and not distribute the PDF to other people.

Is this possible with Acrobat ? Acrobat Pro ? 

This would be a way to avoid huge postal cost with a physical book.

No, you must use a DRM server.
