Questions tagged [drm]

DRM (digital rights management) is the enforcement of restrictions on access control to data through technical means, such as copy protection.

Digital rights management (DRM) refers to technical means to control operations that may be performed on data. For example, a DRM policy might be that a file must not be copiable, or must only be read by a particular person, or that all copies must be deleted after a period of time. When the policy is solely about who has access to the data and not about what can be done with the data, see .

DRM usually specifically refers to restrictions that apply to content covered by copyright, such as music, videos, etc. DRM also applies to application code; see also .
