On January 16, the blockchain digital content copyright certificate system developed by Cover Media was officially launched on the Cover News app. Every original manuscript created by a journalist is “chained on” and a unique certificate of deposit is generated. Cover Blockchain Digital Content Depository System is a copyright management alliance chain based on "Intelligent Media Cloud" 3.0. It is jointly developed by the Cover Research Institute of Artificial Intelligence Research Institute, Communication Research Institute and Blockchain Media Lab. Authorization is automatically generated, and a manual control and management module is developed, which is safe, real-time, standard, and easy to use.
