Encryption and DRM

Last updated: 2026-02-25 15:27:24

Overview
During content distribution, media may be screen-recorded, intercepted, or decrypted and restored, and then redistributed on third-party platforms—resulting in piracy and copyright loss.
Tencent Cloud VOD provides two types of content protection capabilities: HLS Private Encryption (SimpleAES) and Commercial DRM. Commercial DRM is designed for higher-grade rights protection and is suitable for scenarios with stricter security and compliance requirements.

Best Fit
HLS private encryption
(SimpleAES)
Encrypts HLS content; keys are protected via a private protocol.
High: mitigates common browser plug-ins and piracy tools.
High: supports playback on almost all mainstream devices.
Compatibility-first; baseline rights protection.
Commercial DRM (FairPlay / Widevine)
Uses DRM key and license protocols; protection enforced with device capabilities.
Very High: closer to hardware-/system-level content.
Medium: good iOS support; some Android devices may not support it.
Security & rights compliance first.
Use Cases
Use case
Description
Online education
Training courses often involve high production costs and strong anti-piracy requirements. 
If broad device compatibility is critical, we recommend HLS Private Encryption (SimpleAES). 
If extremely strong protection against screen recording and cracking is required and you can accept limited device coverage, choose Commercial DRM.
Copyrighted TV series
Content from professional licensors typically requires rights protection. 
For domestically produced titles, HLS Private Encryption (SimpleAES) is recommended first. 
If overseas licensors (e.g., Hollywood studios) require Commercial DRM, then adopt Commercial DRM accordingly.
How to Use
For how to use HLS private encryption, see HLS Private Encryption.
For how to use commercial-grade DRM, see DRM Encryption.
