I am trying to find a way to prevent a PDF from being printed or downloaded when view from web. Also, it is prefered that user cannot print screen. A print screen will allow someone to recreate the low res image you present, and in this case you could add a watermark to the image.
Okay, I take back what I commented earlier. Just talked to one of the senior guys in my shop and he said it is possible to lock it down hard. What this will do is that if they right click on the 'image' to save it, they will be saving the transparent image instead.
And since the image 'overrides' the iFrame, any attempt to use print security settings prevent pdf download should be shielded by the image, and they should only be able to snapshot the image that doesn't actually exist. That leaves only one or two ways to get at the file Still not totally secure, but protected from your average user. That is not possible.

Yet they have no options to prevent saving at any point, anywhere. There are probably programs that are actually sold just to remove the DRM from Adobe documents and even if not, the point was that the client specified that no downloads be allowed even by users who had access to the private site.

Yet my research has taken me through many years of posters all asking for the same thing. If I find it, and it works, I'm buying it. I wish I had skills as a programmer because I have some pretty good ideas of ways to implement such a product, unfortunately, I do not know how to put these ideas into practical use, security settings prevent pdf download.

In my business, the need for the PDF to not be downloaded is due to not wanting customers to be able to easily share downloaded materials with other people.
I make worksheets, and if they are easy to share, the customer is more likely to email them to a friend. If sharing them is made more complicated, they are less likely to want to go to the trouble. Not being able to download them without having advanced computer knowledge is good enough for me.
Hope this sheds light on a need in the industry. Things like being able to get a screen shot, etc. Hope this helps.

I think I remember it existing in Mozilla Suite back before it got pared down into Firebird, which then became Firefox.
I consider that under 'one of the ways of getting at it that requires digging into the source. I say you can lock it down 'hard' but not 'make it secure. Jonathan Thurft Jonathan Thurft 3, 4 4 gold badges 34 34 silver badges 67 67 bronze badges.
