Abstract

 Healthcare organizations struggle with electronic health records (EHRs) because they digitize medical data. Doctors and patients spend a lot of time accessing EHRs for information, but if the data isn't relevant, access can be blocked. Sharing and retaining medical records is crucial to healthcare. Losing patients' privacy and correct medical information would be terrible. It is one of the main reasons electronic health records must be secure. Modern healthcare infrastructure is notoriously inefficient in data integrity, security, and privacy. However, well-managed and monitored EHRs may reduce security and complexity difficulties. The blockchain's decentralization and trustworthiness make this possible in healthcare. The healthcare delivery system has inherent data management and validation and dissemination issues. Blockchain technology improves access to drugs, hospital assets, drug systems, patient data, and more for healthcare data management. Blockchain technology could improve healthcare by giving doctors rapid access to their patients' medical histories, which is essential for prescription drugs. Thus, a blockchain-based medical record verification and security solution is essential. This article focuses on building a permissioned blockchain-based Ciphertext Policy-Attribute encryption system to protect personal data and restrict medical record access. When all qualities are fine-tuned during encryption, the meta-heuristic model improves. Optimization reduces ciphertext size, encryption costs, and communication costs. Finally, the performance evaluation shows that the proposed method is as reliable and robust as state-of-the-art designs.
