Preserving biosensor users' anonymity over wireless cellular network

A wireless body sensor network takes a significant part in mobile E-healthcare monitoring service. Major concerns for patient's sensitive information are related to secure data transmission and preserving anonymity. So far, most researchers have only focused on security or privacy issues related to wireless body area network (WBAN) without considering all the communication vulnerabilities. However, since bio data sensed by biosensors travel over both WBAN and the cellular network, it is required to study about a privacy-enhanced scheme that covers all the secure communications. In this paper, we first point out the weaknesses of previous work in [9]. Then, we propose a novel privacy-enhanced E-healthcare monitoring scheme in wireless cellular network. Our proposed scheme provides anonymous communication between a patient and a doctor in a wireless cellular network satisfying security requirements.
