Scalable and Secured Personal Health Records Sharing in Cloud Computing

Government and insurance companies moves in to creating Personal health record (PHR) for health information exchange to lower the cost of healthcare, better medical care for the patient and reduced medical errors. PHR system allows patients to generate, administer, organizes and shares their health information with other users as well as healthcare provider. A critical issue in the transition to PHR is the privacy, confidentiality, and security of the information stored. This issue has made some patients and healthcare providers reluctant to accept electronic records. To ensure only the patient and authorized user by the patient access the PHR stored in cloud database is by encryption In this paper to overcome the problem of key management posed by the encryption a novel patient oriented encryption algorithm is proposed.
