Digital rights management (DRM) provides controlled access to digital content through encryption, licensing, and policy enforcement. It prevents unauthorized distribution by combining access controls, persistent watermarking, and secure key management to protect media across delivery networks. Effective DRM balances protection with user experience by supporting scalable deployments, analytics, and interoperable APIs. Implementation considerations include compliance, cross-platform compatibility, performance impact, and integration with content delivery systems to maintain security without disrupting legitimate access.
