The medical environment has evolved from the one centered on the hospital diagnosis to that centered on the healthcare. The healthcare environment is the technology enabling the remote diagnosis for personal healthcare not only of lonesome old men but also of general households. In relation with it, an international standard technology was published recently that transmits the information from the devices to measure the biometric information of persons to the healthcare center or hospital. But, for its actual application into each household, it is necessary to solve the privacy protection problem. Therefore, this paper proposes a new architecture and system to secure the privacy of person for the newly published international standard technology. The proposed technology is expected to provide a more secure and realistic alternative in the future human-centric healthcare home environment. Copyright © 2012 John Wiley & Sons, Ltd.
