DRM

Digital Rights Management (DRM) is, in simple terms, any technology that is built into an electronic product or service with the aim of limiting its range of uses after purchase. It is designed to prevent consumers from using digital technology in ways that do not correspond to the business agenda of a content provider or device manufacturer.

DRM essentially removes the property right of the consumer over the product that s/he has paid for, penalising him or her for using a legal copy.
