What is Digital Rights Management?
Digital Rights Management (DRM) refers to a set of technologies, policies, and enforcement mechanisms used by content owners and software vendors to control how digital products are accessed, copied, modified, and distributed. DRM systems can restrict the number of devices on which content is playable, enforce geographic restrictions, set expiration dates, or prevent unauthorized duplication. In software, DRM overlaps significantly with software licensing and copy protection.
Examples
- A streaming platform uses DRM (e.g., Widevine, FairPlay) to encrypt video content and ensure it can only be played on authorized devices by authenticated subscribers.
- An ebook publisher uses DRM to restrict purchased titles to a specific number of registered devices and prevent file sharing.
- A software vendor uses license key enforcement and obfuscation as DRM measures to prevent unauthorized use of its desktop application.
- A game publisher uses always-online DRM requiring server validation before gameplay, preventing use of unauthorized copies.
Common Applications
- Video streaming and OTT content protection
