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.

Modern society can be described as ubiquitous computing over the concept of information. Information technology(IT) has been developing in a way that relative technologies are integrated to each other. Especially in ubiquitous environment, medical information industry shows significant interest in the U-healthcare service area. This paper will first look into U-healthcare service environment and component of Integrated Medical Information Systems(IMIS). Secondly, it examines the basic technological factors for integrated medical information systems, which is datawarehouse, network, communication standards and technology related U-healthcare service. Finally it proposes how to implement and operate new integrated medical information system for ubiquitous health care service. The system will do point of care(POC) for customers by real time and diagnose them using their various and personal medical data. The information will be communicated back to the customers, which will improve their satisfaction.

최근 IT 패러다임은 인터넷 중심에서 인간과 사물, 컴퓨터가 융합되는 기술로 급속히 전환되고 있다. 이를 위해 인간과 사물, 사물과 사물 사이 네트워크화를 위해서 RFID/USN 분야가 핵심 IT 산업군으로 형성되고 있다. USN을 활용한 다양한 서비스 가운데 u-Healthcare는 큰 사회적 이슈로 대두되고 있다. 이러한 u-Healthcare system의 원활한 활용을 위해서는 u-Healthcare system을 지원하는 미들웨어(Middleware)에 대한 연구가 필요하다. 따라서 본 연구에서는 미들웨어의 기능 중 센서(Sensor)를 통해 획득한 데이터의 정확성을 높이는 방법에 초점을 두었다. 이를 위하여 멀티 스레드(Multi Thread)방법을 u-Healthcare 미들웨어에 적용하여 다양한 어플리케이션에서 요구하는 개별 데이터의 정확성을 향상 시키는 방안을 연구하였다.

In Korea, livestock has grown into the most value-added business in the agricultural and forest industry. But due to the recent outbreak of deadly infectious diseases such as foot-and-mount disease and avian influenza (AI), the demand for IT-enabled cutting-edge management system is getting stronger. As for humans, pilot projects and researches concerning U-healthcare have been carried out since early 2000. So this study explored the current progress of U-healthcare introduction, and suggested the strategies to develop technologies of collecting, processing, and utilizing information; to apply elements for a service model development and prioritization; to provide policy and institutional support. Therefore it is expected to vitalize the livestock U-healthcare in the future through continuous study based on these results.

IT융합기술인 U-Healthcare 서비스는 건강관리, 질병 예방, 사후관리 등 필요한 의료 서비스를 의료기관외의 장소에서 언제 어디서나 서비스를 제공받을 수 있다는 점에서 각광을 받고 있다. U-Healthcare 서비스에서 다루는 대다수의 정보는 개인정보 중에서도 민감한 개인의 건강정보를 포함하고 있어 개인정보보호에 대한 사회적 요구가 높아지는 시점에서 유출에 대한 피해 우려는 더 커지고 있다. 본 논문에서는 U-Healthcare 서비스에서 개인정보를 보호받을 수 있는 보안 요구사항을 도출해낸다. 이 연구를 통해 U-Healthcare 서비스의 보안 수준을 향상 시키고 일반 개인정보보다 피해가 큰 개인건강정보의 유출을 예방한다.

Recently, owing to the development of ubiquitous sensor network and mobile communication technologies, many studies on healthcare system are being carried out. In this paper, we have designed and implemented a mobile u-Healthcare system based on sensor network. The u-Healthcare system is composed of three components: wireless sensor network at home, healthcare center located at remote site, and gateway which relays sensing physiological signals to healthcare center. In order to measure patient's physiological signal three sensors are used: three channel ECG sensor, pulse oximeter, and blood pressure sensor. Each sensor is mounted on a mote which can send gathered signal to the base node using Zigbee communication protocol. Once the base node receives physiological signal from each sensor, the client in the base node transfers the signal to the healthcare center. The received physiological signal at the healthcare center is analyzed and processed using various algorithms. The processed results are compared to the standard healthcare database and appropriate treatment including dietetics and exercise cure would be sent to the patient as feedback using SMS message or healthcare center web site. Each patient can check and manage one's health state every day using the healthcare system and gain a recovery under the treatments from minor health problems.

Due to the convergence between digital devices and the development of wireless communication technology, bit-signal sensor miniaturization, building an Electronic Medical Record (EMR) which is a digital version of a paper chart that contains all of a patient's medical history and the information of Electronic Health Record (EHR), Ubiquitous healthcare (u-Healthcare) that can monitor their health status and provide personal healthcare service anytime and anywhere. Also, the appearance of cloud computing technology is one of the factors that accelerate the development of u-healthcare service. However, if the individual information to be used maliciously during the u-healthcare service utilization, leads to serious problems directly related to the individual's life because if it goes beyond the level of simple health screening and treatment, it may not provide accurate and reliable healthcare services. For this reason, we analyzed a variety of security issues related to u-healthcare service in cloud computing environment and described about directions of secure health information sharing system construction. In addition, we suggest the future developmental direction for th activation of u-healthcare industry.

This paper proposes the U-healtcare middleware that is based on mininumCORBA. Ubiquitous healthcare system is generated by combining the technologies of computer system and medical system. This makes available that the person can receive medical treatment anywhere, anytime at on-line. The Healthcare devices are connected to network system as wire or wireless internet. So, the computer system can gather the vital information from the person at the real time and transfers the information to the server system that processes the medical information. When a medical doctor makes a diagnosis they can get more information about the patient by using the information within the server. Users would like to receive more services in the ubiquitous healthcare system than the traditional medical system. And in U-healthcare system, every healthcare devices and the users have to be connected to network system and the information from them has to be integrated. U-Home Healthcare middleware I proposed in this paper will do everything that I mentioned above.
