Purpose

The purpose for writing this article is derived from the misery and chaos prevalent in the world due to the coronavirus pandemic – since late 2019 and still continuing as of December 2020.

Design/methodology/approach

A blockchain-based solution to verify the country visit trail and disease and treatment history of the passengers who arrive at the immigration counters located at various national borders and entry points is proposed. A fuzzy inference based suspect identifier system is also presented in this article that could be utilized to make further decisions based on the degree of suspicion observed on a particular passenger.

Findings

This paper attempted to put forth a blockchain-based system which consumes the healthcare and visit trail summary of a passenger (appearing for an interview before an immigration officer) and forwards it to a fuzzy inference system to reach to a conclusion that the passenger should be advised to self-quarantine, detained, or should be allowed to enter. Such a system would help to make correct decisions at the immigration counters to check pandemic diseases, like COVID-19, right at the entry points.

Research limitations/implications

The implications of this work are manifold. First, the proposed framework works independent of the type of pandemic and is a readymade tool to check the spread of disease through infected human carriers. Second, the proposed framework will keep the mortality rates under check, which would give ample time for the authorities to save the lives of the people with co-morbidities and age vulnerabilities (Vichitvanichphong et al., 2018). Third, it is a general phenomenon to restrict the flights from the country where the first few cases of infection are discovered; however, the infected person, at the same time, might travel through alternative routes. The blockchain-enabled proposed framework ensures the detection of such cases at no other cost. Finally, the solution may appear costly in the first place, but it has the potential to hold back the revenue of the countries that would otherwise be spent on reactive measures.

Originality/value

As of now no other study or research article provides the solution to the biggest problem persists in the world in this way. The contribution is original and worth applying.

预防 COVID-19 爆发的技术干预

目的

撰写本文的目的源于冠状病毒大流行在世界上普遍存在的苦难和混乱——自 2019 年末以来一直持续到 2020 年 12 月。

设计/方法/方法

提出了一种基于区块链的解决方案，以验证到达位于各个国家边界和入境点的移民柜台的乘客的国家访问轨迹和疾病和治疗历史。本文还介绍了基于模糊推理的嫌疑人标识符系统，该系统可用于根据对特定乘客观察到的可疑程度做出进一步决策。

发现

本文试图提出一个基于区块链的系统，该系统消耗乘客（出现在移民官面前接受采访）的医疗保健和访问轨迹摘要，并将其转发到模糊推理系统，以得出该乘客应该是建议自我隔离、拘留或应被允许进入。这样的系统将有助于在移民柜台做出正确的决定，以在入境点检查 COVID-19 等流行病。

研究限制/影响

这项工作的影响是多方面的。首先，提议的框架独立于大流行的类型，是一种现成的工具，可通过受感染的人类携带者检查疾病的传播。其次，拟议的框架将控制死亡率，这将为当局提供充足的时间来挽救患有合并症和年龄脆弱性的人的生命（Vichitvanichphong等., 2018)。第三，限制从最初发现感染病例的国家起飞的航班是普遍现象；然而，感染者同时可能会通过其他途径旅行。启用区块链的提议框架可确保无需其他成本即可检测此类案例。最后，该解决方案一开始可能看起来代价高昂，但它有可能阻止国家的收入，否则这些收入将用于应对措施。

原创性/价值

迄今为止，还没有其他研究或研究文章以这种方式为世界上存在的最大问题提供解决方案。贡献是原创的，值得应用。
