Scalable and Secure Sharing of Personal Health Records in Web Using Attribute-Based Encryption
Reshma S. Sapakal,  Pankaj R. Chandre
Traditional paper-based health records may result in wastage of paper. Now days internet has grown very rapidly. There are more advances in medical and information technology. So using benefits of both traditional health record can be transfer to electronics health record (EHR) and allow medical people to do their activities in numerous ways. Existing centralized Personal Health Record (PHR) systems has efficiency and security problems. To overcome this problem Personal Health Records are outsourced to third party semi trusted data servers over the web to provide distributed environment. However there is major risk of privacy of personal health information exposed to third party server and to unauthorized users. To assure privacy and security one efficient way is to encrypt PHR before outsourcing it to the internet. There are other issues like scalable key management, efficient user revocation and fine grained access. To achieve scalable and fine-grained access Attribute-Based Encryption is used to encrypt PHR. PHR system is consider as multiple owner, multiple user system. For reducing key management complexity, users are divide into multiple user domains like public and personal. While providing high degree of privacy proposed system shows security, scalability and efficiency from its result analysis.
