“…In the proposed solution, NFTs are used as tamper-proof representation of the unique identifiers assigned to serialized items in the supply chain. Gebreab et al [32] propose an NFT-based solution for improving traceability and ownership management of medical devices. As part of this solution, NFTs are utilized as digital counterparts of physical medical devices to facilitate the tracking, tracing, and authentication of these devices in the supply chain and in the marketplace.…”

Medical devices play a crucial role in the global healthcare system, but their high cost has led to the increasing adoption of refurbished medical devices as a sustainable alternative for hospitals and patients around the world. The repositioning of refurbished devices into the market, however, is accompanied by a number of challenges, including concerns about quality and safety, as well as the risk of fraudulent activities such as counterfeiting. To address these challenges, we propose an NFT-based solution for managing refurbished medical devices that creates a secure, transparent, and verifiable record of the refurbishment process to ensure the safety and quality of these devices. The proposed solution utilizes dynamic composable NFTs as digital representations of medical devices, with replacement parts and certificate documents embedded in a parent-child NFT hierarchy, and reprocessing steps captured and reflected through the evolution of the dynamic tokens. This serves to authenticate and track the movement of refurbished devices while also providing a trustworthy means of managing individual devices and their ownership. Furthermore, the integration of non-transferable NFTs as certificates of refurbishment acts as an effective mechanism for detecting suspect medical devices and instances of fraudulent labeling, thereby increasing buyer confidence and promoting user safety. We leverage the Interplanetary File System to store and keep track of the metadata of the tokenized components of the system. We present the system architecture and implementation details with tested algorithms. We develop a front-end decentralized application (DApp) to interact with the designed smart contracts and showcase their functionalities. We also conduct security analysis to demonstrate our system is resistant to common vulnerabilities and exploits. The smart contract code is made available on GitHub.

In an era dominated by rapid digitalization of sensed data, the secure exchange of sensitive information poses a critical challenge across various sectors. Established techniques, particularly in emerging technologies like the Internet of Things (IoT), grapple with inherent risks in ensuring data confidentiality, integrity, and vulnerabilities to evolving cyber threats. Blockchain technology, known for its decentralized and tamper-resistant characteristics, stands as a reliable solution for secure data exchange. However, the persistent challenge lies in protecting sensitive information amidst evolving digital landscapes. Among the burgeoning applications of blockchain technology, non-fungible tokens (NFTs) have emerged as digital certificates of ownership, securely recording various types of data on a distributed ledger. Unlike traditional data storage methods, NFTs offer several advantages for secure information exchange. Firstly, their tamperproof nature guarantees the authenticity and integrity of the data. Secondly, NFTs can hold both immutable and mutable data within the same token, simplifying management and access control. Moving beyond their conventional association with art and collectibles, this paper presents a novel approach that utilizes NFTs as dynamic carriers for sensitive information. Our solution leverages the immutable NFT data to serve as a secure data pointer, while the mutable NFT data holds sensitive information protected by steganography. Steganography embeds the data within the NFT, making them invisible to unauthorized eyes, while facilitating portability. This dual approach ensures both data integrity and authorized access, even in the face of evolving digital threats. A performance analysis confirms the approach’s effectiveness, demonstrating its reliability, robustness, and resilience against attacks on hidden data. This paves the way for secure data transmission across diverse industries.

The application of blockchain technology in industrial product quality traceability is analyzed to construct a new model of product quality traceability that is mainly based on blockchain technology and supplemented by an identity system. The blockchain-enabled overall technical architecture of an industrial product quality traceability system is explored, and a blockchain-based industrial product full life cycle information traceability system is constructed. First, the weights of the information indicators of different links of the industrial equipment information traceability system were calculated using the EAHP hierarchical analysis method. The manufacturing link had the largest weight, with a value of 18.8%. Second, the system’s functional module design is based on the weights. We designed and developed the industrial product information traceability platform based on the hybrid blockchain chain structure of private chain + alliance chain. Finally, a manufacturing enterprise in the Xinjiang region is taken as the research object, query validation is carried out for the products produced by the enterprise, and the average query time of the system is measured to be 65.376 ms. It can meet the traceability needs of consumers and enterprise users. The research can provide theoretical support and reference for the whole life cycle information traceability of industrial products.
