DRM
Security
Access-control and copy-control mechanisms enforced by software/hardware to restrict content usage.
Definition
DRM enforces licensing rules (playback limits, device authorization, copying restrictions). Implementations may involve device identifiers and online checks.
In plain English
Access-control and copy-control mechanisms enforced by software/hardware to restrict content usage.
Why this matters
Why it matters: DRM can introduce additional telemetry and identifiers, increasing fingerprinting surface and data collection.
Example
Example: A video service requires hardware-backed DRM and periodic license checks tied to a device ID.
