Digital Rights Management (DRM) - DRM feature of Web Code Protector

Introduction

Digital Rights Management (DRM) is a crucial feature in modern web content protection, ensuring that only authorized users can access protected materials. The Web Code Protector includes a powerful DRM system that allows developers to secure their HTML, JavaScript, and CSS code with access control mechanisms.

Why Use DRM Protection?

DRM adds an essential layer of security for:

Premium content behind paywalls
Confidential corporate documents
Time-limited promotional materials
Educational course content

Key Features of DRM in Web Code Protector

Visitor Identification & Licensing

The DRM system assigns a unique Visitor ID to each user using:

Online Identificaiton System (browser footprinting)
Offline Identification IDs (fallback)

Access Code Verification

Generate encrypted access codes tied to specific visitors
Codes can be time-limited (expiry date) or permanent
Uses AES-GCM encryption for secure validation

Secure Verification Overlay

Verification popup appears before content loads
Users must enter valid access code
Customizable interface and messages

Auto-Refresh for Time-Limited Access

Periodically checks if access is still valid
Configurable refresh interval
Prevents unauthorized prolonged usage

How the DRM System Works

1. Generating an Access Code

Enter Visitor ID (or paste from clipboard)
Set Expiry Date (optional)
Click "Generate Access Code" → Creates encrypted code

2. Distributing Access Codes

Generated codes can be copied and shared
Each code is tied to a specific Visitor ID
Optional expiry date for temporary access

3. User Verification Process

When visiting protected page:
- Verification overlay appears
- System detects/generates Visitor ID
User must paste the access code
System decrypts and validates the code:
- Checks Visitor ID match
- Verifies expiry date (if set)
If valid → content loads; if invalid → access denied

Frequently Asked Questions

Is the DRM system 100% secure?

While no client-side protection is completely unbreakable, Web Code Protector's DRM makes it extremely difficult to bypass. It uses strong encryption (AES-256) and multiple verification layers to deter unauthorized access.

Can I revoke access after distributing codes?

Yes! For time-limited codes, simply don't renew them. For permanent codes, you'll need to update your protected content with new verification rules.

Does it work on all browsers?

The DRM system works on all modern browsers (Chrome, Firefox, Safari, Edge) that support Web Cryptography API. For older browsers, it falls back to simpler verification methods.
