Design of blockchain system in BDCP using hyperledger fabric

With the development of the network, the number of digital productions is increasing rapidly and produce the demand for copyright protection of them. However, for a long time, both technological and institutional efforts have made some progress, they have not solved this problem very well. The phenomenon of infringement and piracy is still common among the network. In recent years, with the emergence of blockchain, it is hopeful to propose an excellent solution for this problem by taking its trustworthiness as a bridge and combining encryption technology and protection institution. Taking the idea of the Big Data Copyright Protection system as an example, this paper puts forward a detailed design scheme for the blockchain subsystem. The scheme shows the implementation of system's trustworthiness and a prototype is established using Hyperledger Fabric. We also take an experiment to test the performance of the core operations of the prototype with the observation of the resource utilization which proves that blockchain technology can meet most of the application demands. The goal of blockchain technology and continuous development are expected to bring better experience in the future.
