Abstract:

[Objective] Based on the tamper-resistant master data model, knowledge graph model, and key master data on a blockchain, more secure and reliable identification services can be provided for cross-industry and within-industry applications, which creates a more credible industrial Internet. [Scope of the literature] The article focuses on blockchain-based identification technologies, interdisciplinary researches, and construction of applications for identification services, especially in the field of industrial Internet applications. [Methods] This article presents an architecture of public service applications for industrial Internet identification based on blockchain, expounds the data and methods of public service applications on the chain as well as the sharing mechanisms and smart contracts, and illustrates variations of data on the chain through typical industry scenarios. [Results] By deployment and identification of the master data model, the knowledge graph model, and some key master data of various industries on the chain, a safe and reliable data support service can be provided. [Limitations] Since the public service application for industrial Internet identification covers many industry scenarios, it is not possible for this article to cover all industries and scenarios. In the future, more industry scenarios will be explored. [Conclusions] The industrial Internet identification service based on a blockchain can provide safe and reliable data sharing and traceability for cross-industry and within-industry applications, which can improve the security and collaboration efficiency of data sharing, and provide reliable data service support for optimizing public service applications.
