Abstract
MediLocker is a decentralized healthcare record management system leveraging blockchain technology to address critical challenges in modern electronic health record (EHR) systems. Traditional centralized healthcare data management suffers from security vulnerabilities, limited interoperability, restricted patient control, and single points of failure. This research presents MediLocker, which integrates Ethereum blockchain, smart contracts, Interplanetary File System (IPFS) for distributed storage, and advanced cryptographic mechanisms to create a secure, transparent, and patient-centric healthcare ecosystem. The system ensures data integrity through immutable ledger records and cryptographic hashing (SHA-256), maintains confidentiality via AES-256 encryption, and enables granular access control through smart contract-based permission management. By combining decentralization, cryptographic security, and patient empowerment, MediLocker provides a viable, scalable solution for next-generation healthcare data management that prioritizes data ownership, auditability, and operational efficiency while maintaining clinical acceptability and regulatory compliance
