摘要

在2019冠状病毒病大流行期间,有必要验证一个人的健康状况和身份,以便允许旅行。这是通过纸质证书和集中的数字应用程序实现的。即使在2019冠状病毒病之后,预计在旅行和其他目的时也需要进行此类健康状况核查。因此,需要一个额外的凭证,即“健康护照”,以确定一个人是否满足各种目的的健康要求。这样准备的数字凭证应该是可信的、不可伪造的和可验证的。健康护照的设计应保护最终用户的隐私,并使人们能够控制用于确认其凭据的数据。本文探讨了通用健康护照系统的需求,并使用面向代理的建模(AOM)设计了一个基于区块链的自我主权身份(SSI)系统,该系统与个人健康记录(PHR)集成在一起,以满足这一需求。本文通过在Hyperledger Indy和Aries上实现概念验证,并与PHR - MediTrans集成,展示了该解决方案的可行性。计算了证书颁发和验证时间,发现时间开销最小。该解决方案允许用户在不泄露任何重要个人信息的情况下与验证者验证其凭据。我们的解决方案可以集成到任何PHR解决方案中,因为SSI解决方案作为插件添加到通过移动/web应用程序访问的PHR中。

Health Passport: A blockchain-based PHR-integrated self-sovereign identity system
During the COVID-19 pandemic, it was necessary to validate a person’s health status along with their identity to permit travel. This was facilitated via paper-based certificates and centralized digital apps. Even after COVID-19, it is anticipated that such health status verifications will be required for travel and other purposes. As a result, there needs to be an additional credential, a “Health Passport,” that establishes whether a person satisfies the health requirements for various purposes. Digital credentials so prepared should be trustable, unforgeable, and verifiable. The Health Passport should be designed to protect the end-users’ privacy and give people control over the data they use to confirm their credentials. This article explores the requirements for a generalized Health Passport system and uses agent-oriented modeling (AOM) to design a blockchain-based self-sovereign identity (SSI) system integrated with the Personal Health Record (PHR) to address this requirement. The article demonstrates the feasibility of the solution by implementing a proof of concept on Hyperledger Indy and Aries, integrated with the PHR – MediTrans. Credential issuance and verification time were calculated, and it was observed that the time overhead was minimal. This solution allows users to verify their credentials with the verifier without revealing any significant personal information. Our solution can be integrated into any PHR solution as the SSI solution is added as a plugin to the PHR accessible via a mobile/web app.
