Abstract
Provided is a digital rights management system, in which a process of combining digital content created by the original author with first metadata indicated with rights information of the original author and a process of combining revised digital content with second metadata indicated with rights information of a secondary author, are respectively and separately performed at the server and terminal sides. Thus, the digital rights management system can reduce the load generated at the server side compared to a system in which the server side performs both of the above processes.
