In the conventional method, the patient's record is stored either in the database or the server of the particular hospital or on the server of the third party vendor. In the former method, patient data will not be available to the hospital, which is at a different location. If the server is used by the hospital, other hospitals cannot view patient details when a patient is admitted in the new hospital. A patient-centric data is stored in a cloud environment so that patient, doctors and other relevant people can view the record. Before the data is outsourced to the third party vendor's, data are encrypted. Attribute based encryption is used for encryption as the patient can grant access to the person to whom they want to share data. In order to reduce the key management complexity among patient and other users, multiple security domains are created. The patient will have complete control of his/her medical records patient can share his/her data to family or friends or to other doctors. This method increases the availability, portability and security of the patient record. © Research India Publications.
