This is useful if you want to check whether a particular user has viewed a document yet especially if they claim to have not received it. You may therefore only want to track PDF use for specific documents otherwise users will have to be constantly online. Locklizard provides secure PDF hosting with Web Publisher protected PDF files are stored on a cloud server either hosted by Locklizard or yourselves or you can distribute PDF files securely as you would any other file.
Many providers offering secure PDF hosting or enable you to secure PDF files online, but these are not as secure as you may think. Your unprotected PDF files are uploaded to a server where they are stored, encrypted and DRM controls applied, before being stored again in protected format. This may be fine for ebooks but what about sensitive and confidential company documents? Do you really want them sitting on a server in unprotected format for any length of time?
Your PDF files can never be compromised by server vulnerabilities as they are encrypted locally, uploaded via SSL, and stored encrypted on the server. If you prefer to host secure PDF files yourself then you can distribute them just like any other file email, USB, web site download, etc. It does not matter who has access to your secure PDF files because they are encrypted and can only be viewed by authorized users. So you can make them freely available via a web site for download without worrying about password access controls.
Additional protected PDF documents and decryption keys can be added at a later date by authorized users when they become available without the USB stick having to be returned to you. The administration system where you create users and authorized document usage can be hosted by Locklizard or on your own servers.
This is separate from protecting PDF files locally on your computer so you have greater control over secure PDF distribution of your documents and who has access to them.

Customer Testimonials. However, life is never that simple. Sometimes the requirement to prevent printing is actually to prevent printing that cannot be identified. In other words, whilst printing is to be permitted, per se, there is a desire to prevent printing of the original by others. This means being able to put information onto the printout that identifies the owner of the IPR of the document, and perhaps the person carrying out the printing.
Whilst this does not act to prevent printing where the authorized user creates the print, it means you prevent printing by other people, by exposing the identity of the person who has failed to implement proper document control and document management. A common concern that causes people to prevent printing is the risk that printed documents might be scanned and re-published.
The requirement here is not so much prevent printing, but prevent re-printing. The simplest way to prevent printing in this case is to provide watermarking that will:. One has to be aware that if you do not prevent printing, then you are opening up a potential security weakness by allowing printing, and that you must use one or more of the countermeasures that we have identified in order to reduce the potential for piracy.
If you do not, then you might as well not have bothered with any document security mechanisms. But one assumes that you are sensitive to the nuances between needing to prevent printing as an absolute measure, and the need to prevent printing when you mean unidentified printing or printing that can be readily reprocessed whilst removing your proof of ownership of the content.
Download print prevention software that uses digital rights management DRM controls to prevent printing of your PDF documents and files: reports, elearning and online training courses, confidential documents, etc.
A solution is not without its costs. 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. 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.
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. Therefore the need to prevent the download to start with is not so hard to understand.
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? 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. 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.
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.
You could also control printing from javascript on the client side. 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 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 :. I suggest to modify pdf. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
