Assured and coherent sharing of healthcare data in cloud using cryptography

Abstract

The Healthcare information system (HIS) is a compendious system which is developed with a help of various healthcare employees. This information system helps to manage the entire working system of a hospital in paperless environment. Here all the data’s related to a patient’s are stored in a single database. It offers various benefits to a hospital, but fails to provide the better privateness and security to the data’s stored in healthcare database. Various cryptography algorithms are used by the users to share the health information in cloud, which provides secured data sharing. But still, data breeches is the main problem in cloud. This paper proposes a framework for secure sharing of healthcare data in cloud.
