Abstract
The outbreak of COVID-19 has brought great pain to people around the world. As the epidemic continuing, prevention and control measures become particularly important. Then, the health QR code has been designed to tracing and controlling the epidemic. Through the health code, the confirmed cases and close contacts will be traced quickly. However, the health code records a great deal of residents’ privacy information and if it is leaked, the consequences will be severe. Although some existing health code schemes preserve the privacy, but most of them either do not support fine-grained auditability or are centralized health code storage. Therefore, we propose an auditable and privacy-preserving health QR code scheme based on blockchain.
