Secure and scalable PHR using attribute based encr
no vote
In this paper, we discuss that personal health management record (PHR) is a new patient-centered model of health information exchange, which is often outsourced and stored in a third party, such as cloud provider. We all save dates in the form of encrypted data. Here we propose a novel patient-centered framework and a set of mechanisms to control the data access to PHRs, which are stored in a semi trusted server. We use attribute based (ABE) encryption technology to encrypt each patient's phr file. Different from previous works, in secure data outsourcing, we focus on the scenario of multiple data owners, and greatly reduce the complexity of key management. Multiple security domains for owners and users are divided into users in phr system. By using multiple authorizations, Shinzo Abe ensures a high degree of patient privacy at the same time.
