Robust Security for Healthcare Data Using Blockchain

The healthcare sector has witnessed a rapid digitization of patient records, leading to an exponential increase in the volume and sensitivity of healthcare data.However, ensuring the security and privacy of this data has emerged as a critical challenge due to the evolving landscape of cyber threats.To address this challenge, a novel approach that combines the scalability of cloud computing with the immutability and transparency of blockchain technology to achieve robust security for healthcare data.The proposed hybrid storage framework leverages the advantages of both cloud computing and blockchain to establish a secure and efficient data management system.In this framework, sensitive healthcare data is encrypted and stored on distributed cloud servers to ensure high availability and reliability.Additionally, a blockchain-based distributed ledger is employed to record access logs and maintain a tamper-proof audit trail of data transactions.The integration of blockchain technology enables transparent and accountable data sharing among authorized parties while preserving patient privacy and confidentiality.The results indicate that the hybrid storage model offers superior resilience against various security threats, including unauthorized access, data breaches, and tampering, thus ensuring the confidentiality, integrity, and availability of healthcare data.
