Abstract

Many different digital health records are observed now-a-days, likewise electronic medical record, healthcare record and health-related document system, other systems are also observed for. With the increase in data, paper work becomes cost increasing and unsecure medium but in another way dealing with electronic medium is safe for bulk amount of data with accessing of authorized person. In this paper is implemented on Hospital Cloud Environment, which share health record with individuals who have access rights. In addition, an algorithm Rc6 and Blowfish is used to provide data security and privacy. For access control ABAC and RBAC is used.

Introduction

Cloud computing enables convenient, on-demand network access to a shared pool of configurable computing resources. Essential characteristics of cloud promoting capabilities including on-demand self-service, ubiquitous network access, location-independent resource pooling, rapid elasticity, and measured service. It offers computing services though three delivery models [8] including software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). Cloud computing has grown as a new service model leading to the establishment of numerous cloud based data centers as cost-effective platforms for hosting largescale service applications. However, notwithstanding considerable benefits and services, the problem of security and privacy of medical data access has been significant for service providers. To mitigate this, researchers have proposed numerous techniques and methods. [9] Have proposed a practical hybrid solution for secure data access in cloud, which ensures high data reliability, security and integrity by combining statistical and cryptographic techniques. Electronic health (e-health) services provide efficient exchange of the patient’s data between different entities including nurses, doctors, lab technicians, receptionists, and insurance companies. In e-Health, the data owner represents a content provider who can store and publish health records in the cloud environment for sharing. The cloud-computing paradigm provides great opportunities to support flexible and controlled information exchange. However, authentication and access control issues in the cloud pose serious challenges that hinder the wide adoption of cloud-based e-Health services.

Conclusion

Privacy preservation of medical health records contributes its study towards secure storage of data in cloud environment. Security and privacy is the important concern in every fields, and if talking about outsourced data than the issue becomes more complicated. So, a framework for preservation of privacy based on Hospital Cloud Environment is proposed using RC6 and Blowfish algorithm. For preserving access ABAC and RBAC is used.
