THE HEALTHCARE INDUSTRY ELECTRONICALLY MAINTAINS MEDICAL DATA WHICH HAS PATIENT’S INFORMATION LIKE PATIENT’S PERSONAL INFORMATION, DIAGNOSTIC REPORTS, AND DOCTOR PRESCRIPTIONS. CURRENTLY, SENSITIVE INFORMATION IS STORED IN THE CENTRALIZED STORAGE MODEL. ONE MAIN DISADVANTAGE OF THE CENTRALIZED MODEL IS THAT THE PROBLEM IN PRESERVING USER PRIVACY. THREATS PERTAINING TO THE USER (PATIENT) PRIVACY INCLUDE UNAUTHORIZED ACCESS OF CRITICAL INFORMATION LIKE IDENTITY DETAILS AND DISEASES FROM WHICH A PATIENT IS SUFFERING AND MISUSE OF PATIENTS’ DATA AND THEIR MEDICAL REPORTS. TO HANDLE THIS ISSUE, WE PROPOSE A DISTRIBUTED OFF-CHAIN STORAGE OF MEDICAL DATA USING IPFS (INTERPLANETARY FILE SYSTEM) AND BLOCKCHAIN TECHNOLOGY. THE PROPOSED FRAMEWORK WHILE PRESERVING PATIENT PRIVACY FACILITATES EASY ACCESSIBILITY OF MEDICAL DATA BY AUTHORIZED ENTITIES LIKE HEALTHCARE PROVIDERS (E.G., DOCTORS AND LABORATORY PERSON). MOREOVER, IT ACHIEVES CONSISTENCY, INTEGRITY, AND AVAILABILITY
