DRM or Digital Rights Management System. This system was originally born to control access to legal copies of digital systems. Currently it has several meanings, the most common is the use of technology to control and manage access to data and copyrighted material. It also supports the interpretation of taking control of digital content beyond the people who process and manage it through a program.
Organisations that promote the use of DRM encourage the incorporation of this protection to prevent the disclosure, distribution and – or modification of unauthorised content.
