Traditional healthcare/medical services are intended for medical treatments, but recent services have increased the prevalence of preventive medicine programs gearing toward curbing the expanding cost of social security costs. In this paper, we explain the enhanced ubiquitous healthcare/medical system (E-UMe) and body area networks (BANs) within it. A BAN contains two types of sensor. One is to be worn all the time in order to make continuous or on-demand measurements. The other is invisible to the user measuring during sleep. The system analyzes vital data in the working state, comparing it to the base data recorded at night by BANs. For individual healthcare treatment, it is important to find this base data and compare it with that from daytime. We explain the E-UMe system, introduce two first-step implementations, UMe-1 and UMe-2, and cover BANs and sensors. We discuss 24-hour ease-of-use monitoring using different types of sensors suitable for sleep time and for less constraint during the daytime. We introduce service security and BAN security in the E-UMe system. We then explain BAN security that is deployable to small sensors. We confirm that the system works as a first step toward future individual monitoring.
