In the current open network environment, with the widespread use and dissemination of digital content, digital copyright management and service methods have been paid more and more attention, and have become a current research hotspot. Based on the research and analysis of the existing copyright management and service models, a new digital copyright service model based on registration is proposed for the purpose of better realizing copyright management and infringement monitoring. Based on some of the core techniques such as copyright information registration, efficient extraction and comparison of media fingerprint, and blindly embedding and extraction of copyright identifier, a new model of networkbased digital media copyright service based on registration, fingerprint comparison, and identifier tracking can be implemented to solve a series of market order chaos problems caused by online media piracy and infringement.
