Electronic medical record security sharing model based on blockchain

Abstract

The emergence of electronic medical records has provided great convenience for the storage and analysis of medical data. However, electronic medical records contain a large amount of personal privacy information, it is still very difficult to share medical information among various medical institutions. As the underlying technology of Bitcoin, blockchain technology has the characteristics of decentralization, security, trustworthiness, collective maintenance, and cannot be tampered, it is suitable for data protection and sharing. In this paper, data masking technology and Inter Planetary File System (IPFS) are introduced to build a safe and efficient electronic medical record sharing model based on blockchain. The model can not only guarantee the security of medical data, but also save resources in blockchain.
