What is copy protection?

Copy protection is all about controlling the authority to make copies of a piece of media.  Copy protection software, therefore, looks to restrict who can make copies, and sometimes their type or quality. If you do not have copy protection, then pirates will quickly mass-share your work for free, regardless of your legal rights (copyright).

The practical limitations of making physical copies of works are usually copy protection enough.  Even the humble paperback is not worth scanning and printing.  Other than the serious number of hours needed to scan a paperback, the printing cost, unless you are a commercial printer, is simply prohibitive.  You would not spend 12 hours of your time and $25 in ink to make a single copy when you can buy one in your local mall for $5.95.

In the world of computing, however, copying is a trivial and inexpensive activity. Copying a file from your downloads folder to a piracy site is literally child’s play. Clearly, the traditional limitations that ensure copy protection no longer work in the computer environment. Copy protection now has to be active rather than passive, especially since distribution via email or a cloud server costs nothing.

How can you achieve copy protection when making copies is so trivial?

The first thing to realize about digital copying is that there is nothing wrong with allowing the copying of files in themselves.  The copy is only useful if you can interact with it, whether that be by opening and viewing it in an application or editing its code.  All you really need to do is make sure that only the purchaser can use their copy.

The easiest way to do this is to lock use to an authorized user’s device.  While technically a friend could look over their shoulder or borrow their device, so too could they lend a physical book.  The important thing is that they cannot make new copies that can be used indiscriminately by users who have not paid.

Ultimately, then, copy protection is not a matter of literally stopping someone from copying a file. It’s about making those copies useless to those who do not have the right to use them.  The only realistic way to achieve copy protection is through the use of cryptography. See PDF copy protection for more details on protecting PDFs against unauthorized copying.

  What file types can you secure with software copy protection?

There is no one-size-fits-all software copy protection tool: they vary in what they can secure depending on their focus and underlying technology. Locklizard, for example, is purpose-built to protect PDF documents, offering advanced DRM controls and encryption specifically designed for this format. If you need to secure documents such as reports, training materials, eBooks, or manuals, Locklizard provides effective protection against copying, printing, and unauthorized distribution.

However, software copy protection more broadly can be applied to other file types through different DRM solutions:

  • Video files (MP4, MOV, WMV): Software to copy protect video files typically includes stream encryption, domain restrictions, and playback authorization (e.g., Widevine, Apple FairPlay, Microsoft PlayReady).
  • Audio files (MP3, WAV): These can be encrypted and licensed using media-specific DRM to prevent unauthorized downloads or redistribution.
  • Office documents (Word, Excel, PowerPoint): Some DRM systems, like Microsoft IRM, offer basic restrictions within the Office ecosystem, though these are generally less secure and easier to bypass.
  • eBooks (EPUB, MOBI): Platforms like Kindle or Adobe ADEPT DRM protect against unauthorized copying and sharing, though their effectiveness varies.
  • Software applications and games (EXE, DLL): Software DRM often includes licensing systems, serial key verification, or online activation checks.

Copy Protection Components

Below are the main components of a good copy protection system.  Each component adds a layer of security that helps enforce copy protection controls.

  • Encryption

    Encryption is used to encode (encrypt) content so that it is only usable if the recipient has the correct key.

    In good copy protection systems, it is also used to lock content to specific devices so that it cannot be easily transferred (along with the key) to an unauthorized device.

  • DRM Controls

    DRM is used to impose restrictions on what an authorized user can do with content so that security cannot be easily circumvented by functionality available within an application.

    For example, the ability to stop printing of a document, or for content to no longer be accessible on a fixed expiry date, or after a number of days of use.

  • Licensing

    Licensing enables content to be linked to a user so that you can control access and use at the user level.

    For example, you may want to restrict a user to being only able to view protected documents on their mobile device in only an authorized office location.

  • Watermarks

    Watermarks can be used to make copying difficult (static watermarks) or to identify a user (dynamic watermarks).

    • Dynamic watermarks may be used as a form of copy prevention, because the individual the content has been licensed to has their own identity associated with it and they most likely won’t want to be identified as the source of copied materials.
    • Static watermarks make it difficult to copy by using background images that blend with the content – e.g. a diffraction or a Moire fringe pattern.
  • Other Security Mechanisms

    A good copy protection system will also control Operating System behavior so that simple methods to circumvent security are prevented.

    For example, stopping screen grabbing and preventing printing to non-physical printers such as file drivers.

Copy Protect documents without passwords using Safeguard PDF security

How to copy protect a document

To copy protect a file in the PDF format, right-click on them in Windows File Explorer and select the menu option ‘Make Secure PDF’.
Then in Safeguard Secure PDF Writer, choose the copy protection to apply:

  1. Prevent printing, allow printing or limit the number of prints.
  2. Add dynamic watermarks to viewed and or printed pages.  Dynamic variables replace actual user and system data when the document is viewed/printed so you only have to protect the document once for all users.
  3. Add expiry.  Make the PDF expire on a date, after a number of views, after a number of prints, or after a number of days from opening.
  4. Lock PDF use to specific locations on a global or user basis.
  5. Log document views and prints.
Safeguard’s default copy protection
  • Stops users editing, copy and pasting content
  • Stops screen grabbing (even from remote connections) and use of Windows print screen
  • Locks PDF files to specific devices so they cannot be shared with others
  • There are no passwords for users to enter, manage, or remove
  • Revoke PDFs at any time regardless of their location
Document distribution

Distribute protected PDFs just like any other file – send by email, upload to a website, etc.  It does not matter who downloads protected documents, as only authorized users can access them.

   How to use Locklizard USB copy protection

USB, flash, or pen drives are typically considered one of the least secure ways to share documents.  Without USB copy protection, once they’re out there, they can be easily lost or stolen.  Safeguard, however, allows you to conveniently hand documents to external parties on a USB device without having to worry.  This is how it works:

  1. Protect your PDF files on your PC using Safeguard PDF Security and add DRM controls by selecting the options you require.
  2. After you publish the document, press “Protect to USB…”.

  3. Select the USB drive you want to publish to and press “Publish All”.

    Configuring USB publication with Safeguard

    Documents are encrypted with copy protection on USB flash drives, ensuring secure offline access.

  4. You distribute your secure USB device to external or internal users. You can also add a password to protect them in transit if you wish – this must be entered before users can access documents on the USB device.
  5. Once they have the USB device, users can open the protected PDF files in the provided viewer application.

  6. Users can also download additional protected PDF documents that they have been authorized to view to their USB devices.  The keystore is automatically populated with keys accordingly.

   FAQs

Does Safeguard support copy protection via USB?

Yes. Safeguard Portable USB allows you to encrypt and apply digital rights management controls to a document and then publish it to a USB device (flash drive, PEN drive, etc.).  On publish, the documents and encryption keys are transferred to the USB drive and locked there, along with the secure viewer application.  The document can then be opened directly from the USB device with no additional software required.  Users can view files offline with full protection – there is no need for an Internet connection.

Is website content copy protection effective?

If you mean protecting the text and images on the website itself, then no.  The browser just doesn’t have enough control or obfuscation to prevent a user from copying or downloading text and images from a website using their browser’s developer mode.  JavaScript can be both edited and disabled to bypass protection.

It’s better to put sensitive content inside of a PDF document, use DRM software to protect it, then provide it as a download on your site.  The document copy protection will be far more effective, preventing copy and paste, printing, editing, screen capture, and more.

How do I copy something that is copy protected?

Well, you can copy the file itself as many times as you want, but any decent copy protection software still stop you from doing anything with its contents.  If you’re asking how to make a copy of the file’s contents, then the method of bypass varies depending on the copy protection software used to secure it.  If the file in question is a password protected PDF or Word file, the answer is easy: use a cracking app such as Elcomsoft or an online tool.  Alternatively take a screenshot and run it through an optical character recognition tool.  If you are in possession of a Locklizard-protected .pdc file, the only route to copy it is to ask the Publisher to enable printing or screenshotting.

Does Locklizard stop duplicate copies of PDF files from being made?

No, doing so is pretty much impossible in the modern era.  Every file uploaded to a messaging application, website, etc. is a new copy.  Instead, it ensures that these copies can still only be opened by authorized users and that all DRM controls are enforced both online and offline.  See How to protect a PDF from being copied.

How do I bypass copy protection?

Bypassing copy protection that was applied using Locklizard is difficult.  The only route users can take is to take a picture of their screen with their phone, but dynamic watermarks will quickly identify them if they share that photo with others.

As for other copy protection solutions:

How do you protect the author of a book from having their work copied by others?

See ebook DRM which covers ebook formats and software protection solutions to prevent piracy.

How can you protect a PowerPoint presentation from being copied?

There are various methods you can use to protect a PowerPoint presentation from being copied.  Password protection is not effective so consider IRM or DRM for stronger security.

Does Locklizard copy protect video files or images?

Locklizard only protects files in the PDF format and videos embedded in PDFs will not play after they are encrypted. Embedded images will still be viewable and will be protected against copying, editing and screenshots.

What is the best way to protect my digital media from piracy?

Using a DRM solution.  For video files and video games the leading solutions are Widevine and Denovo.  For PDF documents, we believe that Locklizard is the best choice.
