This paper explores the integration of blockchain technology in the management and sharing of medical data, specifically through the use of encrypted Non-Fungible Tokens (NFTs) and the InterPlanetary File System (IPFS). We address the traditional challenges of data security, privacy, and interoperability in healthcare systems by proposing a blockchain-based framework. Our study evaluates various encryption algorithms-RSA, RC4, DES, ChaCha20, Blowfish, and AES-to determine the most suitable for encrypting metadata associated with NFTs. Additionally, we analyze transaction fees across four Ethereum Virtual Machine (EVM)-compatible platforms-BNB Chain, Fantom, Polygon, and Celo-to assess their economic efficiency and suitability for healthcare applications. The research aims to demonstrate how blockchain technology can provide a secure, efficient, and transparent method for managing medical data, thus enhancing patient care and operational efficiency within healthcare systems.

摘要

This paper explores the integration of blockchain technology in the management and sharing of medical data, specifically through the use of encrypted Non-Fungible Tokens (NFTs) and the InterPlanetary File System (IPFS). We address the traditional challenges of data security, privacy, and interoperability in healthcare systems by proposing a blockchain-based framework. Our study evaluates various encryption algorithms-RSA, RC4, DES, ChaCha20, Blowfish, and AES-to determine the most suitable for encrypting metadata associated with NFTs. Additionally, we analyze transaction fees across four Ethereum Virtual Machine (EVM)-compatible platforms-BNB Chain, Fantom, Polygon, and Celo-to assess their economic efficiency and suitability for healthcare applications. The research aims to demonstrate how blockchain technology can provide a secure, efficient, and transparent method for managing medical data, thus enhancing patient care and operational efficiency within healthcare systems.
