Design And Implementation Of Identity Resolution System In Industrial Internet Based On Blockchain

At present,Industrial Internet has become the commanding height of the new round of technology innovation and industry competition in the world.Industrial Internet Identity-resolution System supports data interconnection of Industrial Internet through the unified coding scheme,the standard data structure,and the complete data addressing and management methods.With the advantages of device-independence,coding flexibility and multi-dimensional resolution,Handle has become one of the main identification technologies in the system.However,there are some problems in Handle-based Identity-resolution architecture such as proactive tampering and centralized management,which affects the credibility of data access for enterprises.Blockchain has the features of decentralization,anti-tamper,transparency,and contract-autonomy,which is conducive to improving the data security and governance fairness of Identity-resolution System.Leveraging Handle and Blockchain technologies,a Trusted Co-governance Identity-resolution Architecture(TCIA)is proposed and a prototype system is designed and implemented.The system has functions of decentralized identity management,trusted storage,compliant resolution and verification,which satisfies the resolution delay with millisecond level and the throughput up to 380 QPS(Queries Per Second).Generally,c solved the problems of single point failure,data tampering,and governance deviation,achieved the abilities of equality and openness,co-management and co-governance,and trustiness and security for Industrial Internet Identity-resolution System,reduced the cost of trust for data exchange among multi-agents and multi-applications.The main work and innovations are summarized as follows:(1)Proposing a hierarchical blockchain technology structure.The basic principles and technology association of Blockchain are studied by means of hierarchical analysis,while Hyperledger Fabric project is being analyzed towards the structure as an example.It provides a general basis of taxonomy for studying the diversified technology forms of Blockchain.(2)Proposing a Trusted Co-governance Identity-resolution Architecture(TCIA)based on Blockchain.By studying and analyzing the application methods and deployment types of Handle in Industrial Internet,this paper built a decentralized identity service framework,established a trusted storage mechanism for identity data and designed an identity life-cycle management approach so as to form TCIA.It improved the Handle-based Identity-resolution architecture and addressed single point failure,data tampering,and governance deviation issues.(3)Designing and implementing an Identity-resolution system for Industrial Internet based on TCIA.The system is Designed and implemented by Integrating HANDLE.NET and Fabric.Black-box testing is used for functional verification and HANDLE.NET is used to build the control system for performance comparison experiment.Experimental results show that the system supports functions of decentralized identity management,trusted storage,compliant resolution and verification,etc,with the performance of MS-level resolution delay,throughput up to 380QPS and 37%improvement while providing trusted resolution service.
