MIT SafePaths Card (MiSaCa): Augmenting Paper Based Vaccination Cards with Printed Codes

TL;DR

This paper introduces MiSaCa, a card-based vaccination system using digitally signed QR codes for secure, efficient vaccine distribution, administration, verification, and follow-up, suitable for diverse regions.

Contribution

It presents a novel, user-centric vaccination card system with integrated QR codes and a scanner app to improve security and efficiency in vaccine management.

Findings

Proposes a privacy-preserving vaccine distribution framework

Designs a scanner app for clinics and officials

Enhances security with digitally signed QR codes

Abstract

In this early draft, we describe a user-centric, card-based system for vaccine distribution. Our system makes use of digitally signed QR codes and their use for phased vaccine distribution, vaccine administration/record-keeping, immunization verification, and follow-up symptom reporting. Furthermore, we propose and describe a complementary scanner app system to be used by vaccination clinics, public health officials, and immunization verification parties to effectively utilize card-based framework. We believe that the proposed system provides a privacy-preserving and efficient framework for vaccine distribution in both developed and developing regions.
