Transparent Data Dealing: Hyperledger Fabric Based Biomedical Engineering Supply Chain

Blockchain is a decentralized and immutable technology which offers transparency for the digital world, where habitual technology does not. The novel blockchain technology may be employed by many sectors, i.e., healthcare, bank, government services, and supply chain. In particular, Biomedical Engineering Supply Chain (BESC) is a significant part of the medical sector that supplies equipment for the medical sector i.e., Covid-19 testing kit, PPE (Personal Protection Equipment), and medicine. The biomedical product should be able to be traced and the data secured; otherwise, the initial data may be modified and potentially risking patients and the public. Nevertheless, the conventional centralized technology creates a leakage point and as such, compromises data security. This paper proposes a new data dealing approach with using Hyperledger Fabric Blockchain-based BESC to alleviate the centralized controllable and operational issues. The blockchain-based BESC is a novel approach, which can control the users and subsequently eliminate the possibility of tampering within the blockchain system when stored.
