新冠肺炎已经成为一种高度传染性的疾病，它已经在世界各地造成了毁灭性的影响，导致了非常大量的感染和死亡。及时和准确的检测对于有效应对这一大流行至关重要，因为它有助于识别感染，从而减轻(隔离/治愈)感染。在本文中，我们研究了这一挑战，并通过提供一个基于区块链的解决方案来做出贡献，该解决方案结合了自我主权身份、重新加密代理和分散存储，如星际文件系统(IPFS)。我们的解决方案为新冠肺炎考生实施了数字医生护照和免疫证书。我们提供了基于以太区块链的智能合同，成功地编写和测试了为考生维护数字医疗身份的合同，有助于相关医疗当局直接做出迅速可信的回应。我们通过使用不可改变的可信区块链来减少医疗设施的响应时间，缓解虚假信息的传播，并通过DMP来遏制疾病的传播。我们对建议的解决方案的系统设计、开发和评估(成本和安全性分析)进行了详细的描述。由于我们的代码利用了链上事件的使用，因此我们的设计成本几乎可以忽略不计。我们已经在Github上公开提供了我们的智能合同代码。
COVID-19 has emerged as a highly contagious disease which has caused a devastating impact across the world with a very large number of infections and deaths. Timely and accurate testing is paramount to an effective response to this pandemic as it helps identify infections and therefore mitigate (isolate/cure) them. In this paper, we investigate this challenge and contribute by presenting a blockchain-based solution that incorporates self-sovereign identity, re-encryption proxies, and decentralized storage, such as the interplanetary file systems (IPFS). Our solution implements digital medical passports (DMP) and immunity certificates for COVID-19 test-takers. We present smart contracts based on the Ethereum blockchain written and tested successfully to maintain a digital medical identity for test-takers that help in a prompt trusted response directly by the relevant medical authorities. We reduce the response time of the medical facilities, alleviate the spread of false information by using immutable trusted blockchain, and curb the spread of the disease through DMP. We present a detailed description of the system design, development, and evaluation (cost and security analysis) for the proposed solution. Since our code leverages the use of the on-chain events, the cost of our design is almost negligible. We have made our smart contract codes publicly available on Github.
