A Secure Deduplication Framework for Cloud Based Healthcare System

Abstract

Healthcare is the industry which has high impact on the lives of people. It produces large volumes of data. Such data needs help of computing resources available in cloud. Electronic Health Record (EHR) or Electronic Medical Record (EMR) is the data related to one patient permanently stored in storage media. When there is cloud-assisted healthcare system, it can have benefits of scalability and availability. Such system needs both security and deduplication of data for protection of data and efficiency. Many existing systems strived to provide security. Less research is found on the deduplication of medical records. The security also needs to be improved with lightweight approaches. In this paper, it is aimed at both security and deduplication. An algorithm named Secure Electronic Health Record Deduplication (SEHRD) which takes care of security and also deduplication associated with healthcare unit is proposed and implemented. A prototype application is built to demonstrate proof of the concept. The empirical results are analysed and compared with the state of the art.
