| Abstract: | Product anticounterfeiting or fraud has been a primary concern in the global market for many years. Counterfeit products are usually of low quality, which negatively affects a firm’s market share and reputation. Counterfeit goods caused an economic loss of approximately $323 billion in 2017 and 2.5 million net job losses in G-20 economies. The industry has invested enormous human resources and funds in anticounterfeiting technologies to mitigate counterfeiting. With the recent advancement in blockchain and Internet of things (IoT) technologies, the research on anticounterfeiting technologies based on blockchain and electronic labels has become a hotspot. Current anticounterfeiting solutions are somewhat effective in identifying genuine or counterfeit products. However, driven by huge profit margins, counterfeiting technologies have correspondingly been making significant progress, such as cloning or reusing authentic electronic labels. Meanwhile, it is critical to offer a unified and collaborative solution to all participating entities, which can securely share and use data at different stages of the product lifecycle, including product data generation, product data maintenance, and product authentication and verification. Moreover, secure, and efficient product data storage and access should be allowed throughout its lifecycle. Finally, the solution must be cost-effective to encourage its wide adoption in industries. Accordingly, this thesis proposes a hierarchical data storage and access solution based on blockchain technologies. It leverages the major benefits of blockchain technology, such as decentralization, transparency, and non-tampering. Besides adding security, transparency, and data protection (e.g., label protection and abuse prevention, data misuse prevention, data transparency) to the proposed solution with its proven records in security, the overhead and cost of implementing blockchain technologies, particularly smart contracts, are relatively low owing to its automation of primary services running on the blockchain network. Generally, this thesis proposes innovations in the two following key aspects: 1. For anticounterfeiting, this thesis used nonfungible token (NFT) smart contracts to build a data model corresponding to the product lifecycle. 2. For multi-owner shared data storage and access, conforming to the “divide and rule” policy, a multi-owner share and collaborative data access framework is proposed, with target data divided into multiple interleaved segments and assigned to the owners separately to ensure each owner maintains one separate data segment. While joint authorization is required to access the data through smart contracts, ownership and independent control over data are guaranteed. This thesis proposes a novel and highly challenging solution to counterfeiting. Additionally, it meets the industrial requirements and considerably improves the anticounterfeiting scope. Tremendous efforts have been made to maximize the potential for widespread adoption by considering the cost and expenditure as a high-priority matter without compromising the solution’s effectiveness and security when evaluating and selecting appropriate technologies. |
