EPCglobal has proposed the EPC Sensor Network to efficiently integrate and interoperate the RFID and WSN technologies based on the international standard EPCglobal Network. However, it can not deal with the sensor data without EPS. Also, it does not provide enough management function for the sensor data only. This study proposes USN management system that can deal with these weaknesses of EPC Sensor Network. Not only that, it is suitable for the medical environment properly. In the medical environment, it is important for the medical information to be integrated and interconnected via the standard for medical data. This proposed USN management system is based on SIP-HL 7 and can send RFID and WSN data based on SIP(Session Initiation Protocol). It can be interconnected with the existing hospital information system and exchange the information. Also it can design and materialize SIP Interface based on HL7 that allows the medical information to be exchanged and sent.

With the recent establishment of a ubiquitous-based medical and healthcare environment, the medical information system for obtaining situation information from various sensors is increasing. In the medical information system environment based on context-awareness, the patient situation can be determined as normal or emergency using situational information. In addition, medical staff can easily access patient information after simple user authentication using ID and Password through applications on smart devices. However, these services of authentication and patient information access are staff-oriented systems and do not fully consider the ubiquitous-based healthcare information system environment. In this paper, we present a authentication service model based context-awareness system for providing situational information-driven authentication services to users who access medical information, and implemented proposed system. The authentication service model based context-awareness system is a service that recognizes patient situations through sensors and the authentication and authorization of medical staff proceed differently according to patient situations. It was implemented using wearables, biometric data measurement modules, camera sensors, etc. to configure various situational information measurement environments. If the patient situation was emergency situation, the medical information server sent an emergency message to the smart device of the medical staff, and the medical staff that received the emergency message tried to authenticate using the application of the smart device to access the patient information. Once all authentication was completed, medical staff will be given access to high-level medical information and can even checked patient medical information that could not be seen under normal situation. The authentication service model based context-awareness system not only fully considered the ubiquitous medical information system environment, but also enhanced patient-centered systematic security and access transparency.

The general medical information service in hospital recently has been turned into ubiquitous environment. A key requirement in ubiquitous environment is the ability for communication between image viewer realized by DICOM standard and a server supporting medical information to make it possible. In order to apply the proposed scheme, we first realized the server/client networking in mobile terminal environment. Second, we realized DICOM viewer using a PDA to be capable of wireless communication in ubiquitous environment. Third, MIPS(Medical Information Processing System) utilized RFID system to apply the patient's information efficiently. In particular, it showed the capability to communicate image based system unlike previous text based communication.

Recently, medical IT solutions are being provided on a distributed environment basis. In Korea, the necessity of developing a clinical decision support system that can share medical information in a distributed environment has been recognized and studied. The existing clinical decision support system is being built using only medical information of its own within the hospital. This makes it difficult for existing systems to achieve good results in terms of efficiency and accuracy of decision support. In order to solve these limitations, this paper proposes a design and implementation method of clinical decision support system based on common data model in medical field. To explain the application process of the proposed model, we describe the development scenario of the clinical decision support system for the diagnosis of colorectal cancer. We also propose the essential requirements for the development of successful clinical decision support systems. Through this, it is expected that it will be possible to develop clinical decision support system that can be used in various hospitals and improve the efficiency and accuracy of the system.

Recently, U-Healthcare is receiving attentions as a research for reducing the manpower, time in treatment, and etc. Although fundamental technologies, such as sensing, measuring, and etc. are sufficiently investigated. However, Technologies of IT/Medical convergence, which graft IT technologies to medical area, are still in germ. For this, we present a novel healthcare system, which can be applied to the middle sized medical environment, such as private hospital, home, or etc., by means of pre-verified technologies and the expert system. There exist IT element technologies are sufficiently developed in the fields, such as network, database or etc. due to the remarkable developments in IT technologies, and the healthcare is a mission-critical environment. Therefore, it is important not only to investigate novel approaches but also to utilize verified technologies for the U-Healthcare solution. Presented solution provisions automated medical services based on expert system by utilizing the measured data, such as body fat, blood pressure, blood glucose, and etc., in order to provide convenient treatment environment to doctors and nurses. In addition, since people, who do not have medical knowledge, can self-diagnose themselves, it is expected to cut medical costs in various areas. Especially, since each devices communicate with each other through standardized Bluetooth technology, Presented healthcare system is an extensible solution which can easily accept various medical devices. As a result of this, we can safely say that the self measurement and diagnosis services in U-Healthcare are now enhanced by reducing medical cost through our healthcare system.

This paper proposes a secure and efficient anonymous authentication scheme for health information push service based on indoor location in hospital. The proposed scheme has the following benefits: (1)It is just based on a secure one-way hash function for avoiding complex computations for both health care operations users and health care centers. (2)It does not require sensitive verification table which may cause health care centers to become an attractive target for numerous attacks(e.g., insertion attacks and stolen-verifier attacks), (3)It provides higher security level (e.g., secure mutual authentication and key establishment, confidential communication, user's privacy, simple key management, and session key independence). As result, the proposed scheme is very suitable for various location-based medical information service environments using lightweight-device(e.g., smartphone) because of very low computation overload on the part of both health care operations users and health care centers.

In this paper, we propose a secure and efficient RFID-based patient authentication protocol to not only authenticate patients' authenticity but also protect patients' personal medical informations for u-Healthcare environments. Since the proposed RFID-based patient authentication protocol provides strong security and efficiency, it can be used practically for patient authentication and personal medical information protection on the high technology medical environments such as u-Hospital and u-Healthcare.
