Abstract

Modern healthcare sectors need to create an environment which reduces time consuming efforts and other costly operations to obtain a patient's complete medical record and uniformly integrates this heterogeneous collection of medical data to deliver it to the healthcare authorities. Electronic health records (EHRs) have been widely adopted to enable healthcare providers and patients to create, manage and access healthcare information from any place, and at any time. Cloud services provide the necessary infrastructure at lower cost and better quality. Cloud computing when used in Healthcare sector reduces the cost of storing, processing and updating with improved efficiency and quality. But the security of data in the cloud is not satisfactory today. The electronic health record consists of images of the patient‟s record which is highly confidential. The EHRs in the healthcare includes the scan images, DNA reports, X-rays etc., which are considered as the patients private data. Providing security for a huge volume of data with high efficiency is required. This paper introduces a new mechanism in which the EHR images can be secured efficiently and the private data are preserved for later use. Since most of the confidential data are in the form of images, additional care must be taken to secure these images. This is done by reducing the images into pixels and then encrypting those pixels. After the encryption, the single encrypted file is divided into n files and they are stored in the cloud. The original data is obtained by merging the n divided files from the cloud and then decrypting that merged file using the private key. This key is made visible only to the authorised persons as required by the hospital.
