How to open&view password protected PDF in ASP.NET?

[denniswong288@adobeforums.com]

Hi,

I hope someone can help me. Greatly appreciate it.

My website has PDF documents that's available for registered users to view online (through my site) only.

Currently, I can't find any solutions to prevent users from downloading/"save-as" the PDF doc in their local drives, so I'm thinking of password-protecting these PDFs. This will ensure that they'd not be able to view the PDFs even though they download it and save-as local.

However, how do I open these password-protected PDFs on my site?
When I point/redirect to these PDFs, it will prompt for password.

It'd defeat all protection intent if I were to give the password to the user to enter, right?

Example:
1. Response.Redirect("mySecuredPdf.pdf")
2. The browser will then prompt user for password.

What can I do in the CodeBehind to enable the server to OPEN the pdf, and at the same time, pass the correct password to the viewer to open without prompting?

I cannot remove password, because I want to prevent users from downloading and then opening it later, or redistributing the file.

btw, i'm using ASP.NET.

Please help.

Thanks! :)

You need to look at higher level security models that prevent the PDF from being used anywhere except on your site. Adobe offers their LiveCycle Digital Rights Managemetn Server (formerly Policy Server) to address this need.
