We create PDFs and serve them up via Adobe Reader on a website. Someone has asked me if there is a way to prevent users from saving a PDF when they are viewing it in Reader.

I've looked at the options in the SecurityInfo and EncodePermissions functions and don't see an option. Would SetViewerPreferences allow for that? I've looked through Acrobat 9 and don't see a way to do it but a couple of people have told me they are SURE they've seen PDFs you couldn't save.

Is there a way to prevent a user from saving a PDF they are viewing in Reader?

Thanks,

Bob

Here's what I use and it prevents Saving, BUT not Save As.

EncodePermissions (il_pdf_instance_id, 1, 1, 0, 1, 0, 1, 0, 1)

Hope this helps

Hi Bob,

another point of view to prevent from saving is to

hide menu and toolbar of the reader with ...

SetViewerPreferences:

in addition... ;-)

Value 0 for option 1 and option 2 in SetViewerPreferences should feed your needs?

But even if both are hidden the user can make changes to the fields. Then when closing Reader, they will be asked if they want to save changes :(

At least in Adobe XI

Yeah, I can't count the number of times I've had to explain to people that PDF security features that prevent editing/copying/etc are all implemented by Acrobat and Reader but can be circumvented by a host of downloadable tools and editors.

I think we'll look at hiding the menu options. I think the concern here is for kiosk PC's in a common area.
