Disable "Save" functionality when opened trhu web application in IE (.net)

Jul 22, 2009 11:06 PM

HI

 

I am working on a Web Application developed using .net

 

Through the application the users will open pdf files available on the server and view it, in Internet explorer.

 

Now,since this is a sensitive data, we want to restrict the users from "Saving a copy " of the Pdf file.

 

How can i prevent the user from saving a copy of the pdf file

 

I observered that there are options to disable copying, selecting, printing of the pdf file. But i dont find an option to disable Save feature

 

If there are no straight forward approach for this, I would like to know any roundabout ways of achieving this

 

Thanks in Advance.

 

Thanks

Babu

    You can NOT prevent users from saving ANY TYPE of document from the web - PDF, HTML, JPEG, etc.  It's a "feature" of the web.

     

    What you CAN DO is prevent users from being able to use the PDF once it hits their own disk.  To do this, you use powerful Digital Rights Management solutions...

    Was there something unclear about my earlier message that makes you restate the question? 

     

    My answer won't change - nor will anyone else's...

    In that case, they are using a custom PDF viewer - not the standard Adobe Reader.   Also, that doesn't prevent the user from right-clicking on the link in the browser and just doing a "Save link to disk...".  Or for the person who really wants the file, looking at the page source and just loading the URL being passed.   So there are always ways to get the PDF...the important thing is protecting the actual content NOT the method of access.   (also note that the FileOpen product is ALSO doing DRM to protect the content, as I am recommending).

    Its hard to believe that still there is something that cant be achieved through programming

    You can create your own client-server solution.

    You don't want to prevent saving - you want to prevent MISUSE of the file AFTER it has been saved...

     

    That's where good DRM comes into play

    How would you prevent the user saving an image/JPEG in a web page/HTML?  You can't!  Anything that has a URL can be downloaded or saved to disk.   That's how the web works.

     

    So what you need is to control that the document can't be used once it has been downloaded...

    what is your attitude about lrosenth? maybe all that fire should be reserved for figuring out how your company (adobe) can provide digital publishers with a reliable, affordable and easy to use (for both publishers and readers) DRM solution

    I disagree. I also work for a healthcare company and have a problem similar to Babu's with similar restrictions. We don't want the PDF saved at all. DRM is not what we are looking for. Also it may be possible to work around this by using screen print, but I am not looking to prevent users from complicated hacks - I just want to prevent the PDF form from being saved in a basic way. My research so far says that Adobe requires that LiveCycle be purchased to control and manipulate PDFS, but iTextSharp will do it with a little development effort.

    How would you prevent a user from saving a JPEG image on your website to their disk?  If you can solve that, then you can solve the PDF problem.  It's EXACTLY the same issue.

    Thank you for posting that, but the reply in that post is just baffling, as it describes two things, neither of which will have the slightest effect on the bueiness problem. To lola32011: many people have this problem and wish to solve it. This does NOT make it possible to solve it.

    I had a very complicated discussion with a colleague that is a very skilled Web Developer. The problem about the security of web content is pretty difficult.

     

    We came to the conclusion that this problem is about humans and not programmability. It is impossible to secure any content after it has been made available to the user, other than making things difficult without proper authorized software. Still, you cannot blame the user from doing something that is normally permitted by the software environment.

     

    I think that this post is not about ultra-high security, but instead people just want to prevent the ability to store the PDF by using a built in function like Save. They just want to make the users understand that the content is not intended to be stored permanently when it is displayed in a pop-up, for example. That’s all.

     

    Anyways, this is something that can be programmed in a matter of hours and then integrated in the following versions of PDF and Adobe Reader.

    I don´t know if you resolve your problem or not, but I find a solution tha was fine to my situation, opening in a PDF Viwer.

    I blocked the copy and print option as you probably know how, and them blocked the options Hide Menu Bar and Hide tool bars

    from File - Properties - Initial View. So, the save option is omitted.

    For me these options were disabled, if you face the same problem, this can help you: http://forums.adobe.com/message/4013698.

    My users don´t have the knowledge to unblock the bars, so for me was enough.

    You can prevent saving a type of archive, using windows file screen, security permitions or other server tools. However, this would block saving ANY pdf, not just this one in your application. But this has nothing to do with the adobe's software, though.
