DRM-X 5.0 Features
DRM-X 5.0 · PDF Digital Rights Management
PDF Document Protection
Encrypt PDFs, control document access, and retain user-identifying watermarks on authorized printed copies.
DRM-X 5.0 PDF digital rights management combines document encryption, license authorization, and secure reading in ZJGet to help protect digital publications, course handouts, and business documents.

PDF encryptionLicense controlsUser-identifying watermark
Document encryption + rights management
Protect PDFs and manage usage rights
PDF DRM links document access to an authorization policy. Readers need a license and must open the encrypted document in ZJGet; possession of a copied file does not grant reading rights. You can set viewing and printing permissions for your publishing or training business.
02 / AUTHORIZE
License-based reading
Specify which users can access protected documents, how long access lasts, and which permissions apply, including printing and virtual-printer restrictions.
03 / IDENTIFY
Personalized watermarks
Display identifying information while users read. On Windows and Mac, authorized printouts also retain the user-identifying watermark.
PDF security features
Control document copying, printing, and access
Combine document controls, license permissions, and endpoint security settings to suit your readers.
Prevent clipboard copying
Restrict copying document text to the clipboard to reduce direct extraction through copy-and-paste operations.
Printing permissions
Allow or disable printing and set a maximum print count. Meet legitimate paper-use needs while controlling the number of copies.
Block virtual printers
Where supported, restrict virtual printing methods such as “Print to PDF” to reduce risk.
Screenshot and screen recording protection
Combine Smart Prevent Screen Recording and blacklist controls to reduce capture risks. On Windows, supported screenshot and recording attempts can capture only a black screen.
Time-limited reading
Set license start and expiration times, or a validity period beginning at first use. You can also limit the number of opens when needed.
Device binding
Limit the number of devices a user account can authorize. An appropriate device policy helps reduce account sharing.
License revocation
Revoke issued licenses by user or license profile when permissions change, an order is refunded, or distribution rules are violated.
Display output restrictions
Enterprise accounts can enable “Only One Display Allowed.” Wireless casting restrictions add further control over document output.
Environment restrictions
Use supported virtual machine and cloud desktop restrictions to reduce access through environments with additional recording risks.
Feature availability depends on the account plan, operating system, and ZJGet version. Review the DRM-X 5.0 plan comparison ; single-display restrictions may affect multi-monitor use.
Identity protection on screen and in print
One PDF, different users, individually watermarked printouts
The same encrypted PDF can display a different identifying watermark for each authorized user. You do not need to create a separate document for every reader.
On Windows and Mac, printed pages retain the user's identifying watermark when printing is allowed. This helps discourage unauthorized sharing and provides a lead for tracing a leaked paper copy.
- ✓Choose identifying information such as a username or user ID.
- ✓Combine identifying watermarks with printing permissions and print-count limits.
Watermarks help deter and trace leaks but cannot eliminate every risk of photography or photocopying.

How to protect a PDF with DRM-X 5.0
Set document rights
Create a license profile and choose the reading period, printing permissions, and security settings.
Encrypt the PDF
Select the appropriate license profile and encrypt the file locally with the DRM-X 5.0 encryption client.
Distribute the encrypted file
Provide a download link to the encrypted PDF. Users can download it and open it securely in ZJGet on their local device.
Authorize the reader
After obtaining a license, users read the document under the permissions you set.
Verify users and apply authorization rules through your website
Integrate PDF licensing with your website or LMS
DRM-X 5.0 provides XML Web Service APIs for integration with websites, online stores, membership systems, and learning management systems (LMS).
When a user requests a license, your platform checks eligibility, then uses the DRM-X APIs to update permissions and obtain a license. This connects protected document access to your existing business rules.
Authorization examples
- ✓Confirm that a research report order is valid.
- ✓Verify active membership or subscription status.
- ✓Check course enrollment before issuing a handout license.
- ✓Apply the appropriate access period and user-identifying watermark.

Frequently Asked Questions
What is DRM-X 5.0 PDF document protection?
It combines PDF encryption, license permissions, and secure reading in ZJGet. Content providers can manage authorized access, restrict copying and printing, and identify readers through watermarks.
Can DRM-X 5.0 prevent PDF copying and printing?
It supports clipboard-copy prevention and configurable printing permissions, including print-count limits and supported virtual-printer restrictions. Content providers can choose settings available for their plan and platform.
Do user-identifying watermarks remain on printed PDFs?
Yes. On Windows and Mac, authorized printouts retain the user's identifying watermark. When different users print the same encrypted PDF, their paper copies carry their respective identities.

Yes. Updated ZJGet for iOS supports direct reading of DRM-X 5.0 protected PDFs without first converting them to HTML. Use a compatible client version and account plan.

Direct PDF reading is not yet supported on Android. You can convert PDF content to HTML, encrypt it, and provide access through ZJGet.
Can readers open downloaded encrypted PDF files?
Yes. On supported platforms, ZJGet can open encrypted PDFs downloaded to a local device. A valid license is still required, and an internet connection is needed to obtain and verify the license.
Can document access expire or be revoked?
DRM-X 5.0 provides license expiration and revocation. You can manage access during document distribution according to the capabilities of your account plan.
Can PDF protection integrate with an existing website or LMS?
Yes. XML Web Service APIs let your platform verify eligibility and request licenses based on purchases, subscriptions, course enrollment, or other business rules.
