Achieving Secure Personal Health Records Using Multiple-Authority Attribute Based Encryption
S. Dharanya, DNVSLS Indira · 2013
The revolution of medical field is sharing secure Personal Health Record(PHR) via the internet. Personal Health Record(PHR) is a health record where health data and information related to the care of a patient is maintained by the patient. The PHR owner outsource the PHR to the third party servers for the wide database management and for the security. The third party servers are semitrusted servers and hence it is important to provide encryption before outsource the PHR to the third party servers. In this paper we proposed Attribute Based Encryption(ABE) technique for the personal health records stored in the semi-trusted servers. ABE is used to enable fine-grained and scalable access control for PHRs. 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 has full control over her own privacy, and the key management complexity is reduced dramatically.
