Distributed Attribute Based Encryption for Patient Health Record Security under Clouds
Patient Health Records (PHR) is maintained in the centralized server to maintain the patient's personal and diagnosis information. The patient records should be maintained with privacy and security. The privacy mechanism protects the sensitive attributes. The security schemes are used to protect the data from public access. Patient data can be accessed by different people. Each authority is assigned with access permission for a set of attributes. The data access control and privacy management is a complex task in the patient health record management process.
