Security issues in cloud computing for healthcare

ICT infrastructure in healthcare domain is improved with the advancement of technology. Health data consist multi-format data as it has text reports, MRI, CT-SCAN images, & pathological slides. Healthcare domain has a large volume of data which is archived as Electronic Health Record (EHR) and it has to be updated frequently. The data of the patients has to be available whenever and wherever necessary in the future course of treatment as patient history. Such a huge archival of data in the hospital needs Skilled manpower, Information and Communication Technology (ICT) and Civil infrastructure and its recurring maintenance cost. Cloud technology thus provides the necessary infrastructure as pay per usage model and when used in healthcare sector lowers the cost of storage, processing and updating infrastructure with minimum cost. Data of patients which are confidential and private in nature can be stored in cloud by selecting appropriate deployment models as different models have different levels of security.
