        abstract = {The quick move toward digital systems in healthcare has led to widespread use of Electronic Health Records (EHRs). This shift has improved access and efficiency in medical services. However, traditional EHR systems depend heavily on centralized storage systems. This makes them open to unauthorized access, data tampering, and points of failure. Ensuring data privacy, integrity, and safe sharing is still a major challenge in today’s healthcare systems. To tackle these issues, this paper introduces SEC-HEALTH, a block chain-based protocol for safely and decentrally managing electronic health records. The proposed system uses the Ethereum block chain to keep permanent transaction logs and smart contracts for automated access control. Large medical files are stored off-chain with the Inter Planetary File System (IPFS). Meanwhile, cryptographic hash references are logged on the block chain to guarantee data integrity and traceability. Integrating block chain and IPFS reduces the need for complicated encryption methods while improving transparency, availability, and interoperability. Experimental results show that SEC-HEALTH offers a secure, scalable, and tamper-proof framework suitable for managing healthcare data in the real world.},
