What is Digital Rights Management (DRM)?
Digital Rights Management (DRM) is a set of access control technologies used by publishers, copyright holders, and hardware manufacturers to restrict the use of digital content and devices. The primary goal of DRM is to prevent unauthorized redistribution of digital media and restrict the ways consumers can copy content they've purchased.
DRM applies to various types of digital content, including:
- eBooks
- Music files
- Video games
- Software applications
- Streaming media
How Does DRM Work?
DRM technologies implement encryption and authentication mechanisms to control the use of digital content after it has been sold or distributed. Here's a simplified breakdown:
- Encryption: Content is encrypted so that it can only be accessed by authorized users
- Licensing: Users receive specific rights through licenses when purchasing or renting content
- Authentication: Users must verify their identity or device before accessing content
Common DRM Technologies
| Platform | Primary DRM Technology |
|---|---|
| Netflix | Multi-DRM approach |
| Amazon Prime | Microsoft PlayReady |
| Disney+ | Widevine |
| Apple | FairPlay |
| Adobe | ADEPT |
