MEDICAL RECORD FILE STORAGE SYSTEM BASED ON BLOCKCHAIN

Traditional electronic medical records are vulnerable to attacks,making it easy for information to be leaked or tampered with,tampered,and data is difficult to share.In view of these problems,a medical record file storage system based on blockchain is designed by using the characteristics of blockchain distribution,tamper-proof and traceability,which solves the problems of patients'protection of their private data and file sharing among medical institutions.Combined with the permanent and decentralized file storage characteristics of the Interplanetary file system,it relieved the pressure of the high cost and difficulty of the blockchain for the chain of large files.The utilization of digital signature ensured that patients retained the right to access and exercise control over their medical record information.A comparative analysis was conducted between the proposed system and related systems based on its implementation and resulting performance.
