The answer is
Although we should agree that ultimately you cannot prevent some form of document capture (specially through screen capture technology either through phone or computer), the goal is to prevent direct download of original document. Some suggest you turn it into images, but this is not necessary. There is clearly a way, as several cloud services allow you to share pdf files, removing the download option, without converting the PDF to images (a superior method because it retains important properties like word search). Personally, as a user of Outlook email, I use the cloud service it provides, OneDrive. I just want to share the HTML code produced by OneDrive to share PDF files without download and right-click support. I am no expert on HTMl so cannot tell you exactly how it is done, but it might still provide you some insights. Here is the code for one particular PDF I shared (without private information and other bits that seemed unnecessary to me):

Creating a video with QuickTime's screen capture or anything similar kind of defeats all the effort to protect your document file from being copied.
Why dont you show a generated Picture (screenshot) of the PDF?
- Convert pdf to image.
- Use image tag to display the image.
- Disable right click on the image.
In my opinion the other proposed solution is.
- Convert your PDF book to HTML,
- Show the html book in Iframe
This approach will prevent the users to download the file.
I wish I had an answer but I only have Part of one. And I cannot take credit for it but the way to get it is below.
This is a more serious issue than it is being given credit for from the sound of the replies. Everyone is automatically assuming that the content that needs protection is for public consumption. This is not always the case. Sometimes there are legal or contractual reasons that require the site owner to take all possible measures to prevent downloading the file. The most obvious one I can think of has already brought up. The “Action Option Bar” presented by the browser to on almost any file you can left click.
Adobe DRM does nothing about that and worse, Adobe Acrobat cannot even have its own abilities to “Save” blocked as part of the “DRM” protection. This option comes up even in Reader no matter what other security selections you have chosen.
In our case, Adobe Acrobat was purchased solely to provide some degree of protection for their own format. It is hard to believe that Adobe will let you prevent printing, prevent editing, prevent even opening without a password or you can really go all out and use a certificate for your encryption. Yet they have no options to prevent saving at any point, anywhere. Instead offering the consolation of telling you “Don’t worry: The copy they download without your permission will also have the same DRM on it as well”. Unfortunately that was not the sole purpose of the purchase and half a solution is no “solution” at all. There are probably 100 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. Therefore the need to prevent the download to start with is not so hard to understand. While conversion to FLASH may give you the download protection, you lose all the rest. Unless I can find a way to prevent opening, saving etc for a Flash File. Next, is it possible to password protect a Flash file from opening when clicked on?
The “partial fix” that I was finally able to get to work as needed still only disables all the “right click” functions but it does include a nice “Warning Box” where I can explain that the User has already agreed NOT to download, print, save and so on just to have access to the page. I am not sure if I could post the code here or whether it is acceptable to paste links either but a Google search for "Maximus right click" will take you to it. And it was one of several examples, it just happened to be the one I could implement the easiest and worked better than the others. Credit where credit is due.
Another option I was given by someone was a product called “Flipping Book”. And the user above suggestions for “Atalasoft” ( I had already found that and have sent a request for more information). Hopefully it will be “The Solution” and I can implement it in time to help. It seems to me that this is a place where there is an obvious need for a one-step packaged solution and usually "The Laws of Nature" take care of such an Imbalance in short order. Yet my research has taken me through many years of posters all asking for the same thing. Looks like someone would be able to make a nice living off a “simple” way to add a little more "protection" to “PDFs” (or other documents, images etc) for the people who obviously are in need of it. 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.
if you want to provide a solution, well, there just isn't one. You would have to be able stop the user running a program that can access the buffers in the GPU to prevent them grabbing a screen shot. Anything displayed on the screen can be captured.
If you decide to send a file where the contents are not accessible online, then you need to rely on the security that the end product/application uses. This will also be completely breakable for an extremely determined pserson.
The last option is to send printed documents in the post. The old fashioned way using a good courier service. Costs go up, time delays are inevitble - but you get exactly what you are after. A solution is not without its costs.
Always happy to point out the obvious :)
That is not possible. Reading is downloading. When a user is reading a file, browser is downloading that file to temp. So even if you disable the download button, the user can click "File -> Save As" or copy that file from temp folder.
There are a few things you can do:
Method 1
The following code will embed a PDF without any toolbars and hide the print/download icons
<embed src="{URL_TO_PDF.PDF}#toolbar=0&navpanes=0&scrollbar=0" width="425" height="425">
Method 02
Using Google Drive
Right click on pdf and goto Share(below image)
Then go to Advanced option in left bottom
Tick Both check boxes. After copy embed link and paste it to your src. No download and Save drive option is not allowed
If you encrypt the PDF you can control how printable and changeable it is.
Print settings:
- None
- Low res (150 dpi)
- high res (max dpi)
You can also prevent folks from copying/pasting from your PDF, and even do that while allowing screen readers access (visually impaired folks can still read your PDFs).
You haven't mentioned what you're using to build the PDFs so the details are up to you.
Alternative: You can create annotations that are only visible when printing. Create a solid box over the entire page that only shows up when printed -> No useful printing.
You might be able to do the same thing with layers (Optional Content Groups) as well, not sure.
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 you can do is convert the pdf to an image/flash/whatever and wrap it in an iFrame. Then, you create another image with 100% transparency and lay it over top the iFrame (not in it) and set it to have a higher Z-value than the iFrame.
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 screen 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...which requires digging straight into the source code to find the image file inside the iFrame. Still not totally secure, but protected from your average user.
(disclaimer - I work for Atalasoft)
If you present your PDF documents with the Atalasoft web image viewer, you can prevent the PDF from being downloaded. You could also control printing from javascript on the client side.
I suggest to modify pdf.js: remove the download button, convert pdf (at backend part) to some intermediate format of pdf.js and put watermark also at server side.
