Identity-based privacy preservation framework over u-healthcare system

Abstract

The digitization of patient health information has brought many benefits and challenges for both the patient and doctor. But security and privacy preservation have remained important challenges for wireless health monitoring systems. Such concerns may result in reluctance and skepticism towards health systems by patients. The reason for this skepticism is mainly attributed to the lack of assurances about the way patient health information is handled and the implications that may result from it on patients' privacy. This paper proposes an identity-based privacy preservation framework over u-healthcare systems. Our framework is based on the concepts of identity-based cryptography and non-interactive key agreement scheme using bilinear pairing. The proposed framework achieves authentication, patient anonymity, un-traceability, patient data privacy and session key secrecy, and resistance against impersonation and replay attacks. © 2013 Springer Science+Business Media Dordrecht(Outside the USA).
