A Design of U-Health System on Smart Phone Using ISO/IEEE 11073 PHD Standard

In these days, U-Health indicates that health care and medical services can be applied in real-time with the support of wired and wireless communication technology. It has emerged to give solutions for many social issues including medical expenses, aging of populations, and the absence of medical experts. In the case of Mobile, U-Health system is a service in which the mobile device provides to user an interface to interact with standalone medical devices. However, most medical devices adopt heterogeneous protocols and standards which fully depend on their manufacturers. To solve this issues, a standard ISO/IEEE 11073 PHD(Personal Health Device) has been developed by IEEE Personal Health Data Working Group. This standard provides techniques to assure compatible extensibility of the U-Health system by defining the standards which are responsible for managing and exchanging health information of the user between PHD and remote servers. For this reason, we designed a U-Health system on smart phone using the ISO/IEEE 11073 PHD standards, and secured communicate with SSL through the web interface. Then, we implemented a management application on smart phone using ISO/IEEE 11073 PHD standard in order to assure compatible extensibility among other types of PHDs from various manufacturers. Based on the result achieved from our implementation, the proposed U-Health system could be utilized as a realtime service which could be deployed in mobile environment from the reality.
