Digital rights management (DRM) systems function to protect copyright interests in digital content by controlling access and usage. DRM uses technologies to limit how users can interact with protected materials, such as restricting copying, sharing, or modifying files. By encoding the content and tying it to specific user permissions, DRM ensures that copyright holders retain control over their intellectual property. This has become increasingly important in protecting music, films, and e-books in the digital marketplace. While DRM aims to safeguard creators’ rights, it can also raise concerns about user freedom and access to purchased content.
