Distributed File Storage Model using IPFS and Blockchain

Abstract

In current scenario the patients’ medical report is stored digitally in medical industry. The report consists of patients’ details such as patients’ private details, medical reports, and doctor prescriptions. This sensitive information is stored in centralized storage model. The disadvantage of this system is that there is problem in safeguarding user’s security. The problems such as illegal access of private data such as identity data and illness of the patient, and their medical reports. To address this issue, distributed file system of medical data using Interplanetary File System and blockchain technology is proposed. Where hash value of the report is stored in blockchain thus reducing the size of blockchain and the file is stored in IPFS. In IPFS the file is stored as hash value of the file. This framework preserves patient privacy and facilitates easy access of details of patients by authorized users such as doctors and patients. From this framework availability, integrity and consistency was achieved.
