BHEEM: A Blockchain-Based Framework for Securing Electronic Health Records

In the present era of smart cities and homes, the private information of the patients such as their names, address, and disease is being breached on a regular basis, which indirectly related to the security of electronic health records (EHRs). The existing state-of-the-art schemes handling the security of EHRs have resulted in data being generally inaccessible to patients. These schemes struggle in providing the efficient balance between the data privacy, need for patients, and providers to regularly interact with data. Blockchain technology resolves the aforementioned issues because it shares the data in a decentralized and transactional fashion. This can be leveraged in the healthcare sector to maintain the balance between privacy and accessibility of EHRs. In this paper, we propose a Blockchain-based framework for efficient storage and maintenance of EHRs. This further provides the secure and efficient access to medical data by patients, providers, and third parties, while preserving the patient private information. The goals of this paper are to analyze how our proposed framework fulfills the needs of patients, providers, and third parties, and to understand how the framework maintains the privacy and security concerns in the healthcare 4.0.
