Privacy Preserving System Using Attribute Based Encryption for e-Health Cloud

Kushal P. Kulkarni, Arati M.Dixit

Abstract: Cloud computing is generally a distributed computing over a network. It plays an important role in healthcare integration costs, optimizing resources in a new era of innovations. Many healthcare providers and insurance companies today have adopted some form of electronic medical record systems, most of the medical records stored in centralized databases in the form of electronic records. Typically, a patient may have many healthcare providers, including primary care physicians, therapists, physicians and other medical practitioners. Patient may use multiple healthcare insurance companies for different types of insurances, such as medical, dental, vision, and so forth. Sharing of personal medical records is a patient centric model of health information exchange which can be stored at third party such as cloud providers. The confidentiality of the personal health records is major problem when patient uses commercial web based systems to store their health data, because it can be viewed by everyone. Providing privacy for their own medical records is a promising method to encrypt the files using various cryptographic approaches. There are various issues such as risks for privacy of records, scalability in key management and flexible access have the most important challenges towards achieving fine grained and cryptographically data access control. To achieve fine-grained and scalable data access control for PHRs, we uses attribute based encryption (ABE) techniques to encrypt each patients medical record file. This survey describes new approach for secure storage and controlled sharing of patients health data.
