In response to the current rampant piracy of Internet criminals and the difficulty of protecting the rights of contents authors, with reference to the existing copyright protection systems or platforms, a set of digital content resource registration and service systems have been designed and implemented. It mainly includes modules such as registration management, user management, content management, identification code management, tool management, and information push. Users can register different types of digital works metadata on the system, including but not limited to video, audio, image and other types. After user registration and system review, the system will produce and distribute copyright identification codes based on the work metadata and platform information to be released. The user can use the local tool provided by the system to load the identification code into the work, or use the tool to parse the identification code from the work. Users can use the parsed identification code as evidence for rights protection.
