Embodiment Construction

[0024] Such as figure 1 As shown, the blockchain-based distributed digital rights management (DRM) system provided by the present invention has a blockchain network supporting smart contracts, a distributed public ledger, content publishers and content consumer accounts, and DRM content encryption module, DRM content authorization module, DRM agent module, DRM content authorization smart contract, DRM content playback equipment (including both software and hardware), and content distribution platform, etc.

[0025] Blockchain network that supports smart contracts: a P2P network composed of multiple nodes, each node has a copy of the distributed public ledger, and the nodes communicate with each other to synchronize the ledger, following the same consensus mechanism (including but not limited to PoW Workload proof mechanism, PoS equity proof mechanism, DPoS entrusted equity proof mechanism and SPoS super node equity proof mechanism). Each node has a virtual machine running sma...

Abstract

The invention relates to a distributed digital rights management (DRM) system based on a blockchain. The method belongs to the technical field of digital copyright protection and the technical field of blockchain. The system comprises a blockchain network supporting an intelligent contract, a distributed public account book, a content publisher, a content consumer account, a DRM content encryptionmodule, a DRM content authorization module, a DRM agent module, a DRM content authorization intelligent contract, a DRM content playing device, a content distribution platform and the like. The blockchain distributed public account book records the content copyright information and the content license of the encrypted digital content besides recording the account state, the transfer transaction,the smart contract code and the like, and the content copyright information and the content license both contain protected content encryption keys. Content encryption keys of digital content and content licenses authorized to consumers by content publishers are safely managed on blockchain, content copyright management is open and transparent, and DRM content authorization can be directly carriedout between any content publisher and the consumers in a point-to-point mode on the Internet through the system.

Description

technical field [0001] The invention relates to a digital rights management (DRM) system, in particular to a blockchain-based distributed digital rights management (DRM) system. It belongs to the field of digital copyright protection technology and the field of block chain technology. Background technique [0002] DRM, the English full name is Dight Rights Management, and the Chinese full name is Digital Rights Management. DRM is a technology for content publishers to protect (or limit) the right to use digital content by using encryption technology. Digitized content includes documents, pictures, software, music, movies and various videos, etc. With the advent of the 5G network and 4K ultra-high-definition era, the distribution of digital content is becoming more and more convenient, the quality and value of digital content are getting higher and higher, and the technical requirements for digital content encryption and protection are also getting higher and higher. The t...
