Blockchain Technology in Securing E-Health Records: An Intelligent Approach to Data Privacy

The advent of digital transformation in healthcare necessitates robust measures to secure electronic health records (EHR) against evolving cyber threats. The paper presents a comprehensive framework leveraging blockchain technology. In the proposed methodology, the use of blockchain, IoT, and wearable devices have been proposed. By using Ethereum as the platform of the blockchain the system checks for the integrity and confidentiality of the data. CNN helps in improving the Anomaly detection of patterns in EHR data, the Isolation Forest helps in the aspect of security of the data. The Proof of Authority (PoA) consensus mechanism elevates identity and reputation for the validation of transactions adding to the system’s security. That is why the given results reveal the better performance of the "blockchain-based EHR system" compared to the existing healthcare systems, including Legacy Health Systems and Medicare Solutions that has 15% advantage. The proposed system achieves high efficiency level, with a measured efficiency of 96%. The framework, written in Python, stands for a privacy-friendly approach to HIM, and potential for new revolutionary means of healthcare data organization and patients’ data protection.
