Debendranath Das, Sushmita Ruj, Subhamoy Maitra

TL;DR
SecureVAX introduces a blockchain-based vaccine passport system that enhances security, privacy, and interoperability by integrating smart contracts, IPFS, and cryptographic techniques to address forgery, unauthorized access, and data integrity issues.
Contribution
It presents a novel blockchain-enabled framework combining off-chain and on-chain cryptography with IPFS for secure, verifiable vaccine passports, improving upon existing digital solutions.
Findings
Successfully deployed on Ethereum Sepolia test network.
Demonstrated secure storage and verification of vaccine data.
Enhanced privacy and tamper resistance in vaccine passport management.
Abstract
A vaccine passport serves as documentary proof, providing passport holders with greater freedom while roaming around during pandemics. It confirms vaccination against certain infectious diseases like COVID-19, Ebola, and flu. The key challenges faced by the digital vaccine passport system include passport forgery, unauthorized data access, and inaccurate information input by vaccination centers. Privacy concerns also need to be addressed to ensure that the user's personal identification information (PII) is not compromised. Additionally, it is necessary to track vaccine vials or doses to verify their authenticity, prevent misuse and illegal sales, as well as to restrict the illicit distribution of vaccines. To address these challenges, we propose a Blockchain-Enabled Secure Vaccine Passport System, leveraging the power of smart contracts. Our solution integrates off-chain and on-chain…
