This paper investigates the application of blockchain technology in the management of pediatric vaccination records, focusing on enhancing security, accessibility, and efficiency. Utilizing decentralized platforms, our study integrates smart contracts, encrypted Non-Fungible Tokens (NFTs), and the InterPlanetary File System (IPFS) to address data integrity and transparency challenges. We evaluated various encryption algorithms—RSA, RC4, DES, ChaCha20, Blowfish, and AES—for securing sensitive health data. The framework’s performance was assessed across four Ethereum Virtual Machine (EVM)-compatible blockchain platforms: Binance Smart Chain, Polygon, Fantom, and Celo. This analysis highlights the system’s ability to leverage blockchain features to streamline vaccine record management, potentially reducing errors and enhancing the reliability of health data access.

摘要

This paper investigates the application of blockchain technology in the management of pediatric vaccination records, focusing on enhancing security, accessibility, and efficiency. Utilizing decentralized platforms, our study integrates smart contracts, encrypted Non-Fungible Tokens (NFTs), and the InterPlanetary File System (IPFS) to address data integrity and transparency challenges. We evaluated various encryption algorithms—RSA, RC4, DES, ChaCha20, Blowfish, and AES—for securing sensitive health data. The framework’s performance was assessed across four Ethereum Virtual Machine (EVM)-compatible blockchain platforms: Binance Smart Chain, Polygon, Fantom, and Celo. This analysis highlights the system’s ability to leverage blockchain features to streamline vaccine record management, potentially reducing errors and enhancing the reliability of health data access.
