Design of Digital Film and Television Projection System Based On Blockchain Technology

Abstract

Digital Rights Management (DRM) is widely used to protect digital content and has made a major contribution to protecting digital content. However, traditional DRM technology has shortcomings, such as centralized and opaque copyright and transaction information. In order to solve the security problem of centralized management of digital movies, a digital movie distribution system architecture based on blockchain technology is proposed. Provide authenticity and traceability of data and business logic in film trading, license certification, projection control and other fields. It is developed through the decentralized consensus mechanism and decentralized IPFS storage mechanism using smart contract scripts in the blockchain. Create efficient and accurate implementation and reduce manual intervention and authorization to ensure traffic control throughout the working day. Our mechanism allows rights holders to set prices for different content usage rules according to their own wishes. Customers have the flexibility to choose the usage rules they want to purchase. We have also developed a licensing framework based on blockchain, which is close to the current DRM standard and easy to promote.
