Digital rights management (DRM) is an umbrella term that refers to access control technologies used by publishers and other copyright holders to limit usage of digital media or devices. DRM can also refer to restrictions associated with specific instances of digital works or devices. To some extent, DRM overlaps with copy protection, but DRM is usually applied to creative media (music, films, etc.) whereas copy protection typically refers to software.
