About Haihaisoft DRM-X

How Does Haihaisoft DRM-X Work?

Haihaisoft DRM-X is a leading Digital Rights Management solution. Its core concept tightly binds content encryption with license authorization. Encrypted multimedia or PDF files are like a locked vault, while the license serves as the only unique and non-replicable “digital key.”

1.Core Workflow

The DRM-X workflow balances high-level security with a streamlined and user-friendly experience.

1. Content Encryption: Multimedia files, PDFs, or eBooks are encrypted and cannot be accessed without authorization.
2. Content Distribution: Encrypted files can be freely distributed via USB drives, cloud storage, download links, or any delivery method.
3. Intelligent Detection: When users attempt to open the file using the Xvast Browser, the system automatically checks whether a valid license exists.
4. License Acquisition: If no valid license is detected or the license has expired, the client prompts the user to log in. After successful authentication, a personalized license bound to the user account is issued. This process can be customized via DRM-X integration APIs.

2.License-Based Fine-Grained Control

Licenses in DRM-X are not just access keys but flexible policy management tools. Different Rights can be assigned to different user groups:

• Time Control: Absolute dates (start/end dates) or relative durations (valid period after first access).
• Usage Count Limits: Precise control of playback or access count.
• Hardware Binding: Licenses can only be used on the original authorized device.

• Advanced Copyright Protection:

  • Blacklist-based screen recording blocking
  • Haihaisoft Smart Prevent Screen Recording Technology
  • Dynamic watermarking (username, IP address, etc.)
  • PDF Rights control (copying and printing restrictions)

How DRM-X Protects Multimedia Content

DRM-X 4.0 adopts industry-leading encryption architecture and anti-piracy technologies to protect videos, audio files, PDF documents, web resources, and Zoom meetings.

1.Core Encryption Technology: Full-Length Byte-by-Byte Encryption

Unlike traditional DRM systems that only encrypt file headers, DRM-X 4.0 applies comprehensive protection:

• High-Strength Proprietary Algorithms combining international standards with Haihaisoft’s private security protocols.
• Anti-Tampering and Anti-Debugging Technologies with integrity and signature verification.
• Full-Length Encryption where every byte of the file is encrypted and unreadable without authorization.
• Key Separation Architecture ensuring no keys are embedded in encrypted files.

2.Full Coverage Across Digital Content

DRM-X goes beyond audio and video, extending its protection across the entire digital learning ecosystem.

• Audio & Video: Secure playback of mainstream and ultra-HD formats
• Documents & eBooks: PDF encryption with copy, print, and time restrictions.
• Web & HTML5 Resources: Protect JavaScript, CSS, and images to prevent content theft.
• Dynamic Website Protection: High-speed real-time encryption via Linux-based Nginx for Xvast

3.Multi-Layer Anti-Piracy Protection

Encryption is only the first step. DRM-X mitigates the “play-and-record” loophole through the following technologies:

• Hardware Binding using unique device identifiers
• Haihaisoft Smart Prevent Screen Recording against current and future recording tools
• Dynamic Digital Watermarking displaying user-identifiable information for deterrence and tracing

4.Xvast Secure Browser Kernel

All security logic is integrated into the dedicated Xvast Browser, built on the Chrome engine with embedded DRM protection:

• Memory-Level Decryption with no plaintext files stored locally
• Seamless User Experience with instant license acquisition and smooth playback
