论文摘要
Covid-19导致了史无前例的社会距离政策在全球范围内执行。随着政府寻求恢复其经济，开放工作场所和允许旅行的需求可能会减轻社会疏远的要求，同时还可以保护医疗服务。在这项工作中，我们探讨了所谓的免疫护照的有争议的技术和现在的证券：一项用于发行和验证抗体证书的分散的，具有隐私权的协议。我们考虑抗体证书系统的含义，开发一套风险最少的原则以及其评估的安全框架，并证明这些原则在实践中可能会得到满足。最后，我们还开发了两个其他协议，以最大程度地减少个体歧视，但仍可以估算集体传输风险。我们使用这两个方案来说明抗体证书及其替代方案的公用事业私人关系权衡。
COVID-19 has resulted in unprecedented social distancing policies being enforced worldwide. As governments seek to restore their economies, open workplaces and permit travel there is a demand for technologies that may alleviate the requirement for social distancing whilst also protecting healthcare services. In this work we explore the controversial technique of so-called immunity passports and present SecureABC: a decentralised, privacy-preserving protocol for issuing and verifying antibody certificates. We consider the implications of antibody certificate systems, develop a set of risk-minimising principles and a security framework for their evaluation, and show that these may be satisfied in practice. Finally, we also develop two additional protocols that minimise individual discrimination but which still allow for collective transmission risk to be estimated. We use these two protocols to illustrate the utility-privacy trade-offs of antibody certificates and their alternatives.
