PDF Security and DRM Packages in Depth Comparison

Security and Digital Rights Management (DRM) systems try to protect copyrights and digital contents by limiting access by users to contents. They provide facilities for electronic publishers to distribute their precious contents to prevent any illegal distribution and usage.

In this article we’re about to analyze features, weaknesses and restrictions about variety of DRM, Protection and Security packages for Adobe Portable Document Format (PDF). The comparison is based on system analysis, personal experiences and the provided information and demos in vendors websites.

The comparison is based on several parameters including:

Licensing methods:

Offline Licensing : Licensing without need for License servers and Internet connection which is suitable for offline users.
Standalone Licensing : This licensing method is usually provided as a License Generator application. This method is suitable for small businesses or individual self-publishers.
Standalone Web-Based Licensing : In this method all required licensing and user management components are hosted on Publisher web servers.
Hosted Web-Based Licensing : In this method all required licensing and user management components and pages are hosted on DRM vendor website.
Indirect Licensing : Indirect licensing is usually used to provide reseller mechanisms for protected pdf documents redistribution.

Distribution Controlling Mechanisms:

User-Based Identification: This identification is usually based on user information, and passwords which are provided by DRM users. This method provides a minimum distribution management control but ease of use.
Computer-Based Identification: This authorization system is based on user computer. There are several hardware information which is commonly used by DRM vendors including : Hardware Serial Numbers (Mainboard, CPU, HDD, MAC), Volume Serial Numbers and specific hardware information. This method provides maximum security and distribution management control over the protected pdf documents.
Domain Authorization : Support for domain licensing instead of per user/computer authorization. In this method, licenses are server based using online Licensing server. This method is ideal for internal company document security and local networks.

Protected Document Features:

Protected PDF Changes : User ability to insert comments, notes, attachments or modifications on a protected pdf.
Combined Licenses : Support for Combined licenses which are required to open a protected pdf document. Each license may come from a separate server or publisher.
Offline Viewing : Support for the protected pdf documents to be accessible for offline users.
Support Embedded PDF Contents : Support for embedded contents (flash, video, sound, 3D models and ..),  to be used within a protected pdf pages.

Supported User Rights:

Printing Rights : Support for users printing rights.
Page Print Count : Limitations on number of pages user can print from protected pdf documents.
Clipboard Rights : Limitations on accessing the system clipboard when opening a protected pdf document.
Opening Count : Limitations on number of times user allows to open a protected pdf.

Timing:

Expiration Dates : Expiration time controlling system.
Working Times : Support for opening time limitations for protected pdf documents. This method is ideal for implementation of trial based systems for protected pdf documents.

Security Level:

Reversing Protection : Protection against Reverse Engineering methods and tools.
Screen Grabbers Protection : Protection against screen grabber programs and Print Screen.
Virtual Machine Detection : Locking the protected pdfs to Virtual machines (VMware, Virtual PC, Wine and …)), will cause security holes in Computer-Based Identification systems. Locking a protected pdf to a virtual machine is equal to loosing protected pdf distribution control as virtual machine hardware info and serial numbers are not unique.
Virtual Printers Detection : Detecting virtual printers and preventing users from printing to these printers. Virtual printers are usually used to convert printing outputs to standard portable document file formats like PDF, PostScript or … Printing to a virtual printer will completely unprotect the protected pdf document by saving a raw documents as the result of printing outputs.
DRM Removers : Programs which can attack/remove the security/protection systems from protected document.

Integration:

Standalone Programming Interfaces : Standalone Programming Interfaces (APIs) are used by programmers to link and integrate current systems with DRM Security, Protection and Licensing features.
Web-Based Licensing Interfaces : Web-Based Licensing interfaces are placed on DRM vendor website.

Installation: Components, Plug-ins or DRM Managers needed to be installed on user computer in order to access the protected contents.

Supported Operating Systems: Supported operating systems for opening protected documents.

Supported PDF Viewers: Supported operating systems for opening protected documents.
