Healthcare has become an indispensable part of the modern world. People have started to focus on healthcare more than ever before. With the advent of technology, healthcare records are now digitally stored, known as electronic health records (EHR). These EHRs contain sensitive and confidential information about a patient's condition and medical history. However, they are vulnerable to data breach attacks. Also, they are highly centralized, hence forming a single point of failure, which may lead to data losses, security, privacy, and trust issues between various stakeholders. The mentioned problems pose a need for a secure, reliable system that maintains privacy among the users. The paper proposes a blockchain-based healthcare management system to solve the problem above. The system is based on Hyperledger Fabric, a distributed ledger platform that helps us achieve security, confidentiality, flexibility, and scalability. The model aims to use smart contracts and digital signatures to achieve modularity, role-based working, and a high level of security while performing all the necessary functions efficiently.
