A Lightweight and Secure Framework for Hybrid Cloud Based EHR Systems

Conference paper
Part of the Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering book series (LNICST, volume 224)


Recently Cloud based Electronic Health Records Systems have been developed and are being used in the healthcare industry. Albeit the various benefits of the technology, security, trust and privacy are a major concern. In this paper, we present a secure and affordable framework for EHR storage, leveraging the properties of hybrid cloud in securing data in addition to building low power back-end cluster constructed using low cost single board computers (SBC). We detail requirements for a secure cloud based EHR framework and present the system architecture based on the publisher/subscriber model. The framework is developed and tested on a Hadoop based cloud cluster using SBCs as nodes. Efficiency of the framework is measured in terms of response time for various sizes of Data Blocks containing EHRs.
