由于全球感染人数及COVID-19死亡人数不断增加，寻找根本解决方案以减少疾病及感染传播面临重大挑战。早期发现、隔离感染者和追踪可能的接触者非常重要。本文提出了一种综合方法，将医院/实验室，COVID-19阴性人员，阳性人员和联系人连接到基于云的联盟区块链系统，以确保可靠的COVID-19传播控制。所提出的模型保证了对人员状态的真实的监控、跟踪和更新，无论是正常的、接触的还是阳性的COVID-19病例，并且相关的更新基于区块链智能合约规则的执行结果在区块链中完成。追踪感染者及其接触者是使用物联网传感器来确定他们之间的接触时间和空间距离。GPS/蓝牙/UWB被用作物联网传感器技术，以确定感染者与接触者之间的距离。拟议的区块链以太坊系统智能合约通过Remix IDE由solidity编程语言实现。所提出的方法经过测试，成功地检测了接触案例，并在基于云的区块链系统上准确地应用智能合约规则来管理不同的人的状态。由于使用所提出的模型计算的距离在一米的距离不超过11厘米的误差率。© 2021 Little Lion Scientific
Due to the increasing number of infected people and the number of deaths from COVID-19 over the world, there is a big challenge towards finding a radical solution to reduce the spread of disease and infection. The early detection, isolating the infected persons and tracing possible contacts are very critical. This paper presents an integrated approach that connects hospitals/laboratories, COVID-19 negative persons, positive persons, and contact persons to a cloud-based consortium blockchain system to guarantee reliable secured COVID-19 spread control. The proposed model guarantees a real time monitoring, tracking, and updating to persons status whether normal, contact, or positive COVID-19 case, and the related updates are done in the blockchain based on the results of execution of the blockchain smart contract rules. Tracking infected persons and their contacts is implemented using IoT sensors to determine contact time and spatial distances between them. The GPS/Bluetooth/UWB was used as IoT sensors technologies to determine the distances between the infected people and those in contact. The proposed blockchain Ethereum system smart contract was implemented by solidity programming language through the Remix IDE. The proposed approach was tested and successfully detected the contact cases and managed the different persons states on the cloud based blockchain system applying the smart contract rules accurately. As the calculated distances using the proposed model in the distance of one meter do not exceed the error rate of 11 cm. © 2021 Little Lion Scientific
