Personal health record
(PHR) is a rising patient-centric model of health information exchange which is
often stored at a third party. Major problem in this scenario is the privacy of
records. To assure the patients control over access to their own PHRs, it is a
promising method to encrypt the PHRs before outsourcing. A new cryptosystem for
fine grained sharing of encrypted data is developed based on Attribute Based
Encryption technique (ABE) in a social networking environment. We propose an
assurance of providing security for the PHR records. Not only providing
security also provides scalability and flexible access to the records. To
achieve fine-grained and scalable data access control for PHRs and to reduce
the key distribution complexity, we divide the system into multiple security
domains where each domain manages only a subset of the users. In this way, each
patient can have full control of their PHR file and the key management
complexity is reduced dramatically. Our proposed scheme is also flexible as it
supports efficient random-demand revocation of user access rights and
break-glass access under emergency scenarios.
