Enhancing Security and Fine-Grained Access Control for Personal Health Record in Cloud Computing
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 2
Abstract
Now a days , personal health record become patient-centric model in which PHR service allows a patient to manage and control personal health data in one place through the web, which has made the storage, retrieval and sharing of the medical information more efficient . For the wide range access it has out sourced in third party storage such as cloud providers. These PHR contains sensitive data that should be protected from unauthorized parties. But while using third party service providers there are many security and privacy risks for PHR. The one way to protect PHR data is to encrypt data before out sourcing. Since the PHR has been accessed by the multiple authorities; we introduce a fine grained attribute based access control in which each party is assigned with access permission for a set of attributes. Division of personal health records users into multiple security domains which reduce key management complexity for owners and users. A high degree of patient privacy is guaranteed simultaneously by exploiting multi-authority ABE.
