DRM for PDFs: Best Practices for Protecting Your Documents

Digital Rights Management (DRM) is a crucial aspect of document security in today's fast-paced digital world, and it is imperative to protect sensitive information online. PDF format is among the most popular digital file formats, widely used for document storage and sharing. However, the convenience of sharing PDF files comes at the cost of potential security risks. Unauthorized access, distribution, and modification of PDF files are some of the significant risks of sharing digital documents.

In this article, we will discuss best practices for protecting your PDF files with DRM.

What is DRM?

Digital Rights Management (DRM) refers to a set of technologies used to control and restrict access to digital content such as movies, software, music, and documents. DRM solutions prevent unauthorized access and distribution of digital content, ensuring that copyright owners retain control over their intellectual property.
DRM for PDFs works in the same way. It adds encryption and other security features to PDF files to prevent unauthorized access, copying, and sharing, as well as detect and deter hacking attempts.

Why Use DRM for PDFs?

While PDFs are among the go-to file formats for digital documents, their security features are somewhat limited. For instance, PDF documents can be easily edited, copied, and distributed without the document owner's consent.
DRM for PDFs solves this problem by adding encryption and access control to PDFs. Once DRM is applied, the document can only be accessed by authorized users with the appropriate credentials. Moreover, DRM tools have additional security features such as watermarks, website blocking, and password protection, among others. These features ensure that the PDF document is protected against both cyber and human attacks.

Best Practices for Protecting Your PDFs

1. Apply Password Protection

Password protection is one of the most basic protection measures available for PDFs. This approach involves encrypting the document with a password that only authorized users can access. Although this method is simple, it is still effective in enhancing the security of PDF documents. It is recommended that the password is complex, unique, and changed regularly.

2. Use DRM Solutions

As stated earlier, DRM solutions are advanced and have a variety of features that enhances the security of PDFs. One example is InfoSaaS, a modern cloud-based DRM solution. It provides both document encryption and access control that allows users to manage and control access to their PDFs. Furthermore, it has monitoring features that track user activity and unauthorized attempts, which enhances security.

3. Watermark your PDFs

Watermarks are graphical overlays inserted into a PDF document to deter sharing or unauthorized copying. Document owners can add text, logos, or images that will show on the document, ensuring that people who receive copies of the document can be traced back to the original user.

4. Restrict Permissions

Restricting user permissions is an effective method of controlling access and protecting PDF documents from unauthorized modifications. With permission restrictions, document owners can limit the users that can edit, print, or copy the document. This method is useful in scenarios where users need to view the document but not make changes to it.

5. Audit Trail

An audit trail reports user activity on a PDF document, including who accessed it and when, which parts of the document were modified, and who did it. This approach is particularly useful for compliance monitoring, ensuring that users adhere to set policies and procedures.


The use of DRM solutions to protect PDFs is essential in ensuring the confidentiality, integrity, and availability of digital documents. In this article, we have discussed the best practices for protecting PDF files, which include using DRM solutions, password protection, watermarking, permission restrictions, and audit trails. By following these best practices, document owners can protect their PDF documents from cybercriminals, unauthorized distribution, and other security-related risks.
