Implementation of Wire and Cable Quality Traceability System by Integration of Identity Resolution and Blockchain

### System Environment Deployment

The development technical architecture of the quality traceability system based on IIoT identity resolution and blockchain technology follows the principles of security, advancement, reliability, practicability, and scalability. Under the Linux operating system environment, the core framework is developed by \"Spring Boot 3.0\" framework, the view is developed by \"Layui 2.5\" framework, the \"Tomcat 8.5\" server is used, the \"Mysql 5.0\" database is used, and it is compatible with mainstream browsers; the mobile client adopts \"Vant 3.0\" framework + \"HBuilder 3.7\" mode to realize multi-terminal adaptation. Blockchain data storage adopts Hyperledger Fabric distributed ledger, based on which it realizes the basic configuration, the application of container, the creation of channels, and the deployment of chain code.

The system's main functions are console, identity management, product management, production batch management, warehousing management, anti-tampering query, and so on. Figure 12 is the identity resolution system monitoring diagram, Figure 13 is the blockchain operation monitoring diagram, and Figure 14 is the product management information diagram, showing the specific information of the cable-related product models. Figure 15 is the warning diagram of the tampering prevention system, according to the product, batch, and code number for the combination of queries to determine whether the tampering, query the system from the blockchain to obtain the internal Hash value of the traceability and automatically calculate the Hash value of the original data, through comparison can be judged whether the original data is true. The regional coverage map shows that the product should be in the region, otherwise it represents tampering. Mobile users enter the traceability management page by scanning the QR code of the products. Figure 16 shows the process traceability diagram of the photoelectric composite cable and the production information traceability of its electric unit. Figure 17 shows the batch and detail diagram of the photoelectric composite cable's procurement receipt and storage stage. Identity authentication through different port access enables enterprises to trace the identity data for controllable open, and different users can scan the code to obtain cable products in the storage of relevant information in the block. The key fusion of identity resolution and blockchain enables enterprises to record the whole process data

Product quality and safety is an important business basis for enterprises. There are many types of wires and cables, and according to the different uses, there are some differences in the manufacturing process and quality standards. Each industrialized country has also introduced the corresponding quality testing standards [33,34]. For example, ANSI/UL 9990, the Information and Communications Technology (ICT) power cable standard released in July 2023, was identified as the U.S. national standard for ICT power cable assemblies. ANSI/UL 9990 certified ICT cable assemblies can be affixed with the UL mark on product packaging, which increases consumer confidence and allows them to identify UL-certified ICT power cable assemblies. As shown in Figure 18, these are the entry-mark requirements for major global markets for major cable products.
