Based on Digital Rights Management Systems (DRMS) a copyright holder is able to control or to restrict technically the digital use of a work. Instruments of technical copy protection are in the center of said systems. They serve to a more or less strict control of digitalized contents and may define how often and how far a work can be used by (entitled) third parties.
