Abstract: The design, implementation, and security measures for personal health records when they are kept in external locations, such as the cloud, are discussed in this study. People can access and organise their lifelong health information using a web-based tool called Personal Health Record. Access to the patient's own PHR is under their control. Before outsourcing the data, we apply attribute-based encryption to ensure the confidentiality of personal health records. Here, we concentrate on various PHR owner scenarios and divide users of personal health records into various security domains to simplify key management for both owners and users. The privacy of patients is ensured to a considerable degree. Our system allows the owner of a personal health record complete control over their data. Extensive security and performance analysis shows that the proposed scheme is highly efficient.
