SESPHR: A METHODOLOGY FOR SECURE SHARING OF PERSONAL HEALTH RECORDS IN THE CLOUD
The broad use of cloud-based services in the healthcare industry has made it possible for various participating entities of the e-Health systems to exchange personal health records (PHRs) at a low cost and with ease. However, putting the private health data on cloud servers leaves it open to theft or disclosure, necessitating the creation of procedures that protect the PHRs' privacy. Consequently, we suggest a technique named SeSPHR for PHR cloud sharing that is secure. The SeSPHR system makes sure that PHRs are controlled from a patient-centric perspective and maintains the maintaining the PHRs' privacy. Patients keep encrypted PHRs on unreliable cloud servers and only give certain people access. on various PHR sections, to distinct categories of users. a setup and re-encryption server, a semi-trusted proxy (SRS) is used to create the re-encryption keys and to create the public/private key pairings. Additionally, the process is safe. It implements a forward and backward access control and protects against insider risks. Additionally, we officially evaluate and confirm the use of the SeSPHR approach using high-level petri nets (HLPN). Evaluation of performance in relation to time Consumption suggests that the SeSPHR approach may be used for safely transferring PHRs to the cloud
