Encrypted Cloud Based Personal Health Record Management Using DES Scheme

Cloud-based Personal Health Record systems (CB-PHR)'s majorly used for management of patient's individual health records. Cloud computing are providing real-time healthcare data sharing in a cost-effective manner. Data security and privacy of maintaining personal health records are main obstacles for the wide adoption of CB-PHR systems, since health information is highly sensitive, so it needed to be protected in highly secured manner. In this paper, we propose a novel scheme using Data Encryption Standard (DES) technique for maintaining health record based on challenges and various securities in existing system. In this scheme, indexes are encrypted under different symmetric keys and also the encrypted data indexes from various data providers can be merge by cloud without knowing the index content. It also provides efficient and privacy preserving query processing with a single data query submitted by data user. Encrypted data will be processed by cloud from all related data providers without knowing its query content.
