DeepHealth: A Secure Framework to Manage Health Certificates Through Medical IoT, Blockchain and Deep Learning

摘要

In order to flatten the curve and lower human-to-human transmission of COVID-19 pathogen, one of the critical suggestions by health professionals is to monitor COVID-19 virus status of each human dynamically which is not a pragmatic solution unless the COVID-19 positive, negative, or symptomatic subjects are identified and have a secure health certificate generated based on daily health status. In this paper, we have developed a Blockchain and off-chain based secure health status and user biometric storage system. The health status is being visualized through a distributed QR code app. We have also incorporated deep learning-based face recognition and QR code recognition system in which the facial features are mapped to the QR code of a subject. We have developed three distributed apps (dApps): for the citizens, hospital authorities, and COVID-19 status checking entities. The system allows, for example, supermarkets, malls, and airports, to inquire about the health status of any subject through our developed application using already installed cameras. Our system will allow full life-cycle of the health certificate and biometric user management: creation through dApps, secure storage at Blockchain and off-chain, privacy-preserving sharing with the community of interest, and dynamic visualization.
