Background technique

Digital Rights Management (DRM) refers to a collection of technologies that control access to digital content and manage usage restrictions. DRM is used by content owners, such as the entertainment industry, to protect and control the use of copyrighted content. Security features associated with such protected content may be unlocked after agreement regarding the use of this content and possible fee payments. Content owners can allow users to access content, but limit how the content can be used. For example, content can only be accessed a specific number of times or for a specific period of time. Other restrictions may relate to printing, copying, transferring, hard copy generation, modification, and the like. These restrictions can be associated with the file as metadata, for example as copyright information.
