Abstract
A system and related techniques detect and manage the set of rights associated with a componentized electronic document, including to separately protect and manage individual text, graphic, audio, video or other parts of a multimedia presentation. Unlike prior digital asset management platforms which could enforce encryption or other protection simply around the entire object, the invention permits individualized control over separate media components, to permit distribution for example of some parts, such as text passages, while preventing unauthorized access or copying of audio, photographic, video or other files or content. The electronic document may maintain a list of media components and the set of rights associated with each such component, and a content server or other source may apply key encryption or other safeguards to guide the delivery of the overall media object or its parts, for instance to view in a browser, print on a printer or otherwise access, manipulate or output the content.
