Encryption and DRM

Last updated: 2024-12-03 15:01:31

Overview
If media files are not encrypted, or if they are encrypted but are decrypted by pirates, they may be sent to a third party for unauthorized playback. VOD offers HLS private encryption and commercial-grade DRM, both of which can effectively prevent various cracking behaviors and safeguard media copyrights.

Use Cases

Description
Online education
Online courses are costly to produce, so it's important to protect them against decryption and piracy.
If your courses demand high playback device compatibility, we recommend you use HLS private encryption.
If you have very high requirements for security and are willing to compromise on compatibility, consider commercial-grade DRM.
Copyrighted TV series
TV series are provided by professional copyright holders, and copyright protection is essential for this type of content.
For TV series produced in the Chinese mainland, we recommend you use HLS private encryption.
If a copyright holder outside the Chinese mainland requires DRM protection, we recommend you use commercial-grade DRM.
