We prevent users from copying text and images and pasting them into other applications.
Unlike Adobe permsissions or restrictions, our copy controls cannot be easily removed.
To create copy protected PDF files, right-click on a PDF in Windows Explorer and select ‘Make Secure PDF”.
In Safeguard Secure PDF Writer select the copy protection controls you want to apply.
Safeguard PDF Security protects PDF fiiles from copying text, printing and screenshots so users cannot share content with others.
Additionally you can:
Copy protection is the Holy Grail of the music and film industries. There have been attempts to make DAT tapes, and then CDs, and DVDs, and now MP3. These industry attempts have not been notable only in their lack of success.
At the heart of the problem is that everything on a computer is a copy – there are no originals! To play a music file, or watch a video, or read a PDF document, it MUST be copied on the computer.
And it follows that, no matter how hard you might try, something that must be copied in order to use it can also be copied! Not exactly rocket science. After all, you can play a music CD and record the output from the speakers if you want to, and no copy protection system on earth can stop you. It’s just a matter of convenience and quality.
So PDF copy protection cannot rely upon the idea that you can stop people copying computer files. It’s just plain stupid.
Well the first thing to do is make sure that the file that people have access to cannot be used without some other information. If you don’t do that then you have no copy protection at all. Because you cannot prevent people copying the file you have to prevent them being able to make any use of it.
Normally this is done using PDF encryption. This technique means that whilst people can (as happens with all files on computers) readily copy PDF files, they cannot make any use of the copied file because it is still encrypted.
Thus, PDF copy protection is not obtained just by trying to prevent people from copying physical files, but by making sure that the files they copy are of no use unless they also have some additional information that they cannot pass on to other people. The secret here is to make sure that the cryptographic key(s) used to decrypt the files cannot be passed on to others. This is achieved by making sure the decryption key is not seen by people and by ‘locking’ it to individual computers. This is a critical feature of any PDF copy protection software.
Protecting PDF files with passwords is therefore useless – it does not provide any copy protection because in order to view the PDF a user must enter a password – if they know this then they can give it to others along with the ‘protected’ PDF file or just remove it in a PDF editor or password removal application.
Apart from being able to stop unauthorized users opening protected PDF files you also need to implement additional controls to prevent copying content when a protected PDF is viewed and or printed.
A good PDF DRM system should stop the following:
And ensure that:
Locklizard uses its own secure PDF Viewers to achieve a higher level of copy protection than other PDF security systems. Protected PDF content cannot be compromised by other applications or the common Adobe PDF security flaws and cracks.
PDF copy protection is not compromised by plug-in failures or conflicts. Plug-ins are potentially so insecure that we prevent them from loading so they can’t compromise security. See Adobe PDF plug-in vulnerabilities.
|NO Adobe Acrobat
We don’t have to update our PDF security product every time Adobe updates Acrobat in order for it to work. We don’t rely on the Adobe Viewer at any time or the Adobe Security Handler due to multiple security issues.
NO passwords are required to grant access to protected PDF content. Users thefore cannot use password crackers to remove copy protection functionality.
|NO temporary files
Protected PDF documents are only ever decrypted on-the-fly in memory and decrypted content is never saved to temporary files.
For a more detailed security overview see our DRM technology.
Download PDF copy protection software that uses US Government strength encryption and Digital Rights Management controls to copy protect PDF documents.
Ensure your PDF files are protected against copying, printing, editing and distribution. Lock PDF files to individual computers and locations so they cannot be shared.
Locklizard DRM security provides superior copy protection to Adobe Acrobat and enables you to protect PDF files from copying without insecure passwords.
