DRM

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. The term is often confused with copy protection and technical protection measures, which refer to specific technologies that control or restrict the use and access of digital content on electronic devices. Such technologies act as components of a complete rights-management system design.
