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 present invention relates 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. The system of the present invention includes a blockchain network supporting smart contracts, a distributed public ledger, content publishers and content consumer accounts, a DRM content encryption module, a DRM content authorization module, a DRM agent module, a DRM content authorization smart contract, and a DRM content playback equipment, and content distribution platforms, etc. In addition to recording account status, transfer transactions and smart contract codes, the blockchain distributed public ledger also records content copyright information and content licenses of encrypted digital content. Both content copyright information and content licenses contain protected Content encryption key. The secure management of the content encryption key of the digital content and the content license authorized by the content publisher to the consumer on the block chain is realized, and the content copyright management is open and transparent. DRM content authorization can be carried out point-to-point directly.

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...
