Dr A AVANI, Dr T BHARATH KRISHNA, Dr D PRANEETH, N SUSHMA 01 01 The broad use of cloudbased services in the healthcare industry has made it possible for various participating entities of the eHealth 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 patientcentric 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 reencryption server a semitrusted proxy SRS is used to create the reencryption keys and to create the publicprivate 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 highlevel 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 Copyright (c) Journal of Science Engineering Technology and Management Science.
