Digital Rights Management broadly refers to systems that attempt to strongly (or sometimes weakly) enforce copyrights on media. It may consist of little more than metadata, but often is seen in the form of strongly enforced access control, in some cases on a hardware level.
Systems often do one or more of the following:
- not allow use of content unless you prove to the (playing) system you should be allowed to
- ...and/or restricts you from moving your content around
- restricts you from making a copy of your content
- allow such actions only when allowed by an authentication system
Some argue that considering the what the bulk of DRM does, Digital Restriction Management would be a more accurate term.
