SMHRW Secure Maintenance of Health Records in Well Organized Way

Abstract: This paper presents implementation of personal health records based on cloud computing systems as it is a sharing personal heath record in third party system such as cloud. Security is provided using balanced Encryption. For maintaining the patient’s information we are providing centralized server for Personal Health Record (PHR). Personal Health Records can be accessed by different types of people with high privacy and security. The security authentications are used to protect the personal data from public access. Patient records can be accessed by different people like medical history, insurance people. Access permissions are provided for particular set of attributes with high security. All the files should be stored in cloud which are semi-trusted servers these, are in encrypted form and also re confidential to other users. There are various issues such as risks of privacy exposure, efficient user revocation, flexible access, scalability in key management and efficient user revocation, the most important challenge is achieving in depth cryptographically enforced data access control. For well organizing of health records we follow the technique attribute mean value to fill the missing values(or) fields and to achieve in depth and scalable data access control for personal health records stored in semi trusted servers, we can use ABE techniques to encrypt each patient’s medical record files. Numerous PHR owners access the same data values in many times. The proposed scheme in this paper is Multi Authority Attribute Based Encryption (MA-ABE) and dynamic modification of access policies, file attributes, break glass access under emergency conditions and it supports on demand attribute revocation. Results are provided with efficiently security and sharing manner.
