Blockchained Industry Information Handoff Based on Internet of Things Devices with Intelligent Customized Object Recognition

Abstract

To determine the quality and safety of each product used in manufacturing, the exchange of measured data between machines, operators, production lines, and manufacturing companies is crucial. In this study, we developed a system with customized object recognition capability for the secure blockchain-based transfer of industry information through Internet of Things (IoT) devices. In the proposed system, product history data are transferred through blockchains through artificial intelligence (AI)-based object recognition. Individual objects are recognized and represented using a unique number sequence for use as a private key on a blockchain. The data history can be automatically secured, and all the data are traceable and trackable. The reliability and validity of the proposed system were verified using the Jetson Nano Developer Kit. The proposed AI-based system is a low-cost embedded system. Based on the open-source cloud computing platform, the required computing resources for blockchain computing and storage are available. In an experiment, the proposed system achieved >99% accuracy within 1 s. Furthermore, the computational cost of the proposed system was 10% that of traditional AI systems. The proposed device can be rapidly connected to IoT devices that require limited manual operation and can be adopted in manufacturing and production lines.

Call for Special Issue Papers: Sustainable Solutions for Internet of Things Using Artificial Intelligence and Blockchain in Future Networks

“…The modern networks must deliver better performance than previous generations to address the necessities of emerging services and applications. Of late, the Internet of Things (IoT) is revolutionizing the existing industry into smart infrastructure presented with advanced data-driven architecture; see, e.g., Jian et al (2022). Nevertheless, with the insufficiency of spectrum resources, efficient resource management and sharing are crucial to achieving all these ambitious requirements.…”

Design of a traceability system for a coffee supply chain based on blockchain and machine learning

“…The machine learning (ML) algorithm in computer vision (CV) systems is superior for classifying and selecting food products because it automatically extracts and evaluates important information from certain visual items (García et al, 2019). ML algorithms can not only classify and locate objects, but also differentiate them based on factors such as color, appearance, shape and size (Jian & Pan, 2022). Therefore, the integration between BC and ML is very significant in ensuring the quality of products produced by a supply chain.…”
