patient-centric model of health information exchange, which is often outsourced to be stored at a third party, such as cloud providers. It help the Patient to stores his data on the cloud. However, there have been wide privacy concerns as personal health information could be exposed to those third party servers and to unauthorized parties. To assure the patient’s control over access to their own PHRs, it is a promising method to encrypt the PHRs before outsourcing. Yet, issues such as risks of privacy exposure, scalability in key management, flexible access, and efficient user revocation, have remained the most important challenges toward achieving fine-grained, cryptographically enforced data access control. In this paper, we propose a novel patient-centric framework and a suite of mechanisms for data access control to PHRs stored in semi trusted servers. To achieve fine-grained and scalable data access control for PHRs, we leverage attribute-based encryption (ABE) techniques to encrypt each patient’s PHR file. And we introduced a new technique which is known as “Break Glass method” which is used in case of emergency.
2. PROBLEM STATEMENT With the rapid development of the cloud computing, personal health record (PHR) has attracted great attention of many researchers all over the world recently. However, PHR, which is often outsourced to be stored at a third party, has many security and efficiency issues. Therefore, the study of secure and efficient Personal Health Record Scheme to protect users' privacy in PHR files is of great significance. Focusing on drawbacks and inadequacies of existing process, definitely there is a need of an efficient system which ensures data security.
3. SYSTEM DESIGN
Keywords: Personal health records, cloud computing, data privacy, attribute-based encryption.
In the proposed system, the personal information of the patient will be stored in a form of data on cloud which will be stored in an encrypted format on the cloud for security purposes. Attribute Based Encryption (ABE) will be used for the process of encryption. This encrypted data will be saved on secured cloud. A QR code will be generated using attributes like patient name and Patient ID. To extract the data from the cloud the user will be required to scan the QR code to access the data. After authentication the decrypted data will be displayed to the authenticated user. The PHR can be shall be accessed by using an mobile application. The decision of granting access rights of this PHR will given to the patient. The patients, doctors will have a right for modification of the information whereas pharmacists will only have right to replace the prescribed medicine. The blow diagram shown below will give a clear idea of our proposed system.
1. INTRODUCTION Personal health record (PHR) has emerged as a patientcentric model of health information exchange. A PHR service allows a patient to create, manage, and control her personal health data in one place through the web, which has made the storage, retrieval, and sharing of the medical information more efficient. Especially, each patient is promised the full control of her medical records and can share her health data with a wide range of users, including healthcare providers, family members or friends. Due to the high cost of building and maintaining specialized data centers, many PHR services are outsourced to or provided by third-party service providers, for example, Microsoft Health Vault Recently, architectures of storing PHRs in cloud computing have been proposed. Personal health record (PHR) is an emerging patient-centric model of health information exchange, which is often outsourced to be stored at a third party, such as cloud providers. However, there have been wide privacy concerns as personal health information could be exposed to those third party servers and to unauthorized parties. To
