摘要

由冠状病毒病(COVID-19)的出现和传播引起的全球公共卫生危机是毁灭性的,需要立即采取对策遏制其传播,特别是在疫情发生后不久就没有任何获批准的治疗方法的情况下。这场危机凸显了目前接触者追踪系统的差距,这些系统需要大量公众参与才能发挥作用,但缺乏公众的高度接受。这种低接受度主要是由于对个人资料私隐和保障资料的担忧,阻碍了现有系统的成功。我们以COVID-19为相关用例,评估区块链在改善接触者追踪方面的应用,并提供有效追踪疫情传播的解决方案。拟议系统的关键要求包括保护用户数据,使用分散的系统保持完全的透明度,以及消除对全球定位系统或个人数据进行接触追踪的需求。概念验证系统使用私有区块链来保护和管理使用移动应用程序或存储价值非接触式智能卡在不同地点收集的数据。联系人跟踪是通过使用收集到的数据通过区块链上的智能合约执行的。我们确认拟议的接触者追踪系统所提供的改进。

Can Blockchain Take Smartphones Out of Contact Tracing?
The global public health crisis caused by the emergence and spread of the coronavirus disease (COVID-19) has been devastating, prompting the need for immediate countermeasures to curb its spread, especially in the absence of any approved treatment shortly after its onset This crisis has highlighted the gap in current contact tracing systems, which require massive public participation to be effective but lack a high degree of public acceptance. This low acceptance is mainly due to concerns regarding personal data privacy and guaranteed data protection, hindering the success of existing systems. We evaluate the use of blockchain to improve contact tracing and provide a solution to effectively track the spread of an epidemic, using COVID-19 as a relevant use case. The key requirements of the proposed system include protecting user data, maintaining full transparency using a decentralised system, and eliminating the need for global positioning system or personal data for contact tracing A proof-of-concept system uses a private blockchain to secure and manage data collected at various locations using a mobile application or stored-value contactless smart cards. Contact tracing is performed via smart contracts over the blockchain using the collected data. We confirm the improvements provided by the proposed system for contact tracing.
