ABSTRACT
This paper presents a comprehensive study on the development and application of a blockchain-based system for efficient and secure healthcare data management. The purpose of the research is to address existing challenges such as data tampering, lack of interoperability, and limited patient control over health records. The proposed system utilizes blockchain technology to ensure data integrity, decentralization, and transparency while enhancing privacy through cryptographic techniques and smart contracts. A prototype model was developed using Ethereum and IPFS for distributed storage and tested on simulated healthcare datasets. The study adopts a modular architecture combining data access control, record validation, and decentralized identity mechanisms. Performance evaluation indicates significant improvements in data traceability, access control, and reduction in unauthorized data modification. The system demonstrates strong potential to empower patients with ownership of their health data while enabling secure sharing with healthcare providers. The conclusion highlights that integrating blockchain technology into healthcare infrastructures can significantly enhance trust, accountability, and operational efficiency. Future work may focus on scalability, real-time data integration from IoT devices, and compliance with health regulations like HIPAA.
