How to disable "save" button on Acrobat Reader?

[Tatiyana]

Dear All,
I am using FOP to generate  pdf file from xml and xsl. The users must not save generated pdf as a file on their computers.
I found on Internet what it can't be done directly from FOP, and I have to postprocess the generated PDF with another tool iText .  This information was dated by 2002.
Do you know has something changed since 2002 regarding the solution of my problem and there is any other way to disable "save" button for generated pdf?
Thank you.
Tatiyana.

There is no way you can enforce this. In order to have the
PDF shown on the client, the content has to be transferred
to the client, and there is no way you can prevent the user
from saving it into a file, unless you already have
extensive control over the user's  browser.

This probably meant that you can prevent the user from changing
the PDF content. This functionality is provided by FOP now, see
