This paper presents a framework that integrates blockchain technology, smart contracts, encrypted Non-Fungible Tokens (NFTs), and the InterPlanetary File System (IPFS) to address the challenges of managing child health records. By leveraging the decentralized, immutable, and transparent properties of blockchain, alongside a suite of encryption algorithms-RSA, RC4, DES, ChaCha20, Blowfish, and AES-our system enhances the security and efficiency of record management. The use of smart contracts facilitates automated and error-free transactions, while encrypted NFTs ensure the uniqueness and privacy of each health record. The system’s performance was tested across several EVM-compatible blockchain platforms including Binance Smart Chain, Polygon, Fantom, and Celo, focusing on key functionalities such as data recording, secure record-keeping, and NFT transferability. The analysis not only demonstrates improved security and efficiency but also underscores the potential for reducing operational costs associated with managing child health records.

摘要

This paper presents a framework that integrates blockchain technology, smart contracts, encrypted Non-Fungible Tokens (NFTs), and the InterPlanetary File System (IPFS) to address the challenges of managing child health records. By leveraging the decentralized, immutable, and transparent properties of blockchain, alongside a suite of encryption algorithms-RSA, RC4, DES, ChaCha20, Blowfish, and AES-our system enhances the security and efficiency of record management. The use of smart contracts facilitates automated and error-free transactions, while encrypted NFTs ensure the uniqueness and privacy of each health record. The system’s performance was tested across several EVM-compatible blockchain platforms including Binance Smart Chain, Polygon, Fantom, and Celo, focusing on key functionalities such as data recording, secure record-keeping, and NFT transferability. The analysis not only demonstrates improved security and efficiency but also underscores the potential for reducing operational costs associated with managing child health records.
