However, all the above research studies have focused on secret key distribution issues, while the specific and unique challenge in biometric authentication, ie, how to merge the payload with the biometric information while preserving the statistical uniqueness of the biometric information, has not been addressed. Furthermore, all the above-mentioned biometric-based key-exchange schemes need critical time synchronization because they need to record biometric information simultaneously at different positions of the same human body, which incurs considerable extra communication overhead in extremely resource-constrained wearable body sensor networks. In addition, one of the biometric features may not be unique and accidental faulted measures (eg, due to hardware or software failures) may malfunction the traditional biometric-based security system. 

In addition, offloading the computing tasks of collected data to the cloud is becoming an important research direction of future wireless biomedical computing. The cloud could provide unlimited storage and computational capability. There are several challenging issues related to the cloud-supported WBSNs. Firstly, the quality of service (QoS) between the wearable body sensor networks and the cloud should be satisfied. The QoS involves the communication, computation, and cloud server response secondly, the security and privacy should be preserved between the users and cloud servers. Especially, the monitored data are private data and should not be disclosed to unauthorized users. Also, the persons who are monitored should be able to control the access of their personal health data from body sensors. Thirdly, the efficient decision support algorithms should be realized in the cloud in order to help medical personnel make appropriate treatment decisions.
