Cloud enabled patient-centric EHR management system

The records that are related to the persons health where maintained in the digital format, Electronic Health Record (EHR), which can be used in time of emergency by medical practitioners and other healthcare providers. This provides the detailed medical information of a patient. Since there is need to provide security to those confidential data that are stored in a cloud. In this paper we are using Attribute Based Encryption which is a technique used to provide security based on patients attributes that are always unique. Here we are using multiple attributes of patient´s record to generate a secret key. At the same time the visibility of attributes is varied depending on the users. The attributes that are used to generate the secret key will also be changed dynamically which enhances the security. In order to make it easy to work with, we are implementing in android phones.
