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.
Prevent print, copying, and sharing of your content. Copy control software that ensures the security and use of your information. Preventing printing of your documents and information ensures users can not produce photocopies or duplicates for other people. With Locklizard document DRM software you can choose to prevent print or limit and control the number of prints allowed.
If you allow prints to be made then our document DRM software will automatically prevent print to file, PDF, or image printers so that high quality copies cannot be readily made. Track print use and dynamically watermark documents to discourage photocopying of printed copies. Safeguard uses US Government strength encryption AES and digital rights management controls to prevent printing of your documents, stop sharing and control use.
See our customer testimonials or read our case studies to see why thousands of organizations use Locklizard PDF security to prevent printing and securely protect their documents. For most companies and individuals this is enough to put them off going for a DRM. Whilst it all sounds perfect and useful on the outside, knowing that you have full control of your PDF documents, it is still not enough DRMs a wide spread tool.
Some DRM platforms still require app installs directly onto the computer. Meaning that there are multiple processes and steps to go through just to view the document. This is not how things are done anymore, especially with cloud computing.
This is something that we wanted to address at HelpRange, by developing a secure document sharing platform with full security and access controls. Now you can share PDF documents with full knowledge that links can be deactivated with the push of a button, IP locking and much more. Whilst a DRM can put in place some preventative measures to protect your PDF document, it cannot stop certain aspects of document theft.
For example, a simple video recording of the document is more than enough to bypass all of the measures put in place. If they are, the decryption key is transparently relayed to the client and the protected document opens. DRM controls are enforced by the Viewer software. Safeguard protects PDF files from printing — it disables printing of PDF documents by default so you do not have to apply any additional controls to stop a PDF being printed.
As well as using Safeguard to stop PDF printing for specific or all documents, you can stop printing on a user basis — you can disable PDF printing for some users but allow printing for others using the same protected document you only have to protect the document once for all users rather than on an individual basis. Documents can be protected with zero prints available to stop PDF being printed and then individual users can be granted print rights by altering the number of prints available.
If you allow printing, you can limit the number of times a PDF can be printed by each user in order to stop users distributing high quality copies of documents to others. Document watermarking is recommended if you allow printing to discourage photocopies being made — see PDF watermarking below. The important issue is not whether you can stop a PDF being copied but whether the recipient of the copied file can use it. If you encrypt a PDF with a password you can give a copy of the PDF to another user along with the password and they can use the file.
So the protection provided is worthless as a useful copy was made that could be used with others. Safeguard effectively stops PDF copying because a copy of the protected file is of no use to another user without the decryption key to open it. Decryption keys are stored encrypted in a keystore which is locked to the device it was registered on — so only authorized users can open protected PDF files. Authorized users must be prevented from saving the PDF in unprotected format so no editing or saving options should be made available and unprotected files should never be stored on disk in temporary files where they could be easily recovered.
For additional security the PDF Reader should prevent screen grabbing, and document owners should disable printing so photocopies cannot be made of printed documents. If you are going to stop document sharing and editing then you have to stop Save As from being used so PDF documents cannot be saved in unprotected formats.
The simplest way to do this is to not have the facility available to begin with. Some products use JavaScript to disable the Save As menu item or short-keys, but JavaScript can be easily removed or turned off in a browser environment and so cannot be used securely.
The only documents that can be copied are protected PDF files and they are useless to unauthorized recipients as they need the correct decryption keys to open them. You might want to think again. The way every browser works is by caching information to disk. And browser environments are possibly the least secure of all because if no software is installed on a device then you have no control over the actual environment so stopping screen grabbing and printing to file drivers is not possible.
See Secure Downloads for additional information on stopping downloads and copying. To stop the browser caching the PDF on the users system, they convert your PDF files to images when you upload them — so the document is no longer a PDF file but consists of just raster images. However, this provides a poor user experience since images are slow to display and print, and features such as search, bookmarks, and annotations are unlikely to be available.
However, if you encrypt a PDF file and the user does not have the decryption key to use it then it does not matter if they can download it. And if you apply DRM and licensing controls then authorized users those given access will be restricted as to what they can do with downloadable PDF files for example not being able to share them with others.
Many cloud based systems claim to stop PDF forwarding — however users can share their login credentials with others so they have access to your documents anyway. If a system uses document links then there is nothing stopping an authorized user emailing those links to other users along with the login information. Some systems state that they lock PDF files to email addresses or domains but that just means that you have to login using that email address or any email address that belongs to the domain.
It does not stop PDF forwarding since authorized users can still give their login credentials to others. That is also true of 2FA codes which provide little extra protection.
There are different levels of protection that we can set and modify, which helps us control how our document is used. Have in mind that you should keep your password somewhere safe in case you forget it.
We are going to introduce two free ways to protect your PDF from unauthorized use. One of its many features is the possibility to secure PDFs. Click on the Edit password , and enter it. Each of these features ensures that the user is not able to convert the document. As you can see here, we are adjusting the Edit password option.
