A Patient-Centered Secured Approach to E-Health

Electronic health records (EHRs) have largely supplanted paper-based systems in order to improve the accuracy, reliability, and accessibility of patient data. Furthermore, EHR security is a major concern that puts patient privacy at risk. User privacy and data security are issues with the majority of third-party hosting solutions. As a result, access control regulations must be restricted and effective procedures for cloud-based EHR data must be developed. Under the suggested system, only authorised individuals will be allowed to update or examine some of the patient's data, ensuring the data's confidentiality. Each EHR record is encrypted by the controlling authority. The requesting user may receive dynamically changing permissions based on authentication and context factors. This paper is to provide security and patient-centric approach to e-health solutions. The patient can have control over their medical records. The potential of data theft grows when users' data is outsourced, and attackers can compromise data. So, the authority verifies the request with the database and then generates the secret key. Then with the key provided, files are shared with the authorized user.
