In today’s digital age, we are all concerns regarding the data privacy, scalability, and interoperability in traditional centralized systems. Blockchain technology has emerged as a promising solution, generating significant interest in secure and decentralized healthcare data management systems. This paper presents a Blockchain-IPFS framework designed to enhance the security, accessibility, and integrity of electronic healthcare records (EHRs). Our research proposes a novel blockchain framework integrated with the InterPlanetary File System (IPFS) to ensure healthcare data security, transparency, and immutability while maintaining accessibility. This framework integrates Ethereum smart contracts with InterPlanetary for patient and doctor registration, it secures the data using Content Identifiers (CIDs), and facilitates the data retrieval mechanism through Aadhar number linkage. This system also integrates cryptographic techniques such as AES-256 encryption to safeguard patient privacy and implements role-based access control (RBAC) for secure data sharing. Our experimental results demonstrate the system's efficiency in reducing gas fees and transaction latency when compared to existing blockchain-based healthcare solutions. Key functionalities such as patient registration, doctor registration, and medical record retrieval exhibit optimized gas consumption, with the framework achieving a 16% reduction in gas fees compared to previous works.
