Personal Health Record (PHR) is an emerging patient-centric model of health information exchange, which is now being outsourced to third party, such as cloud providers. However, this affects the privacy concern of any individual, since personal health information could be exposed to third party servers where there is a chance for getting accessed by unauthorized parties too. So to assure privacy for patients’ control over access to their own PHRs, the best method is to encrypt the PHRs before outsourcing. For this, a novel patient-centric framework is proposed here. With the aid of a semi-trusted server, data

Here wide privacy concerns are considered since personal health information could be exposed to those third party servers and to unauthorized parties. To assure the patients’ control over access to their own PHRs, the attribute based encryption method is used for the PHRs before outsourcing. The application addresses the unique challenges brought by multiple PHR owners and users, in that greatly reduce the complexity of key management while enhance the privacy guarantees compared with previous works. Since ABE is used to encrypt the PHR data, so that patients can allow access not only by personal users, but also various users from public domains with different professional roles, qualifications and affiliations. To fully realize the patient centric concept, patients shall have complete control of their own privacy through encrypting their PHR files to allow fine-grained access. Here single trusted authority (TA) system is used to assure patient centric
