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.

Studies on human-centered services are approaching their highest peak with the emergence of a new concept of the network environment, a ubiquitous environment. Among these ubiquitous service technologies, services related to health care are very closely related to the current social environment. In this paper, With social aging and changes in ubiquitous IT environment, studies on health care, which is among the essential application services and which has been defined as a key application technology, and studies related to it have been conducted. In addition, healthcare services, which are essentially applicable to the ubiquitous environment, were suggested by analyzing existing healthcare studies and drawing from them the requirements for such. This paper proposes management protocol for serious case except from health care research. This system is constructed database using RFID, it has location information. It provides procedures to consistently monitor the status of patients and process the outcome in real-time.

The emerging of ubiquitous computing and healthcare technologies provides us a strong platform to build sustainable healthcare applications especially those that require real-time information related to personal healthcare regardless of place. We realize that system stability, reliability and data protection are also important requirements for u-healthcare services. Therefore, in this paper, we designed a u-healthcare system which can be attached to the patient's body to measure vital signals, enhanced with USN secure sensor module. Our proposed u-healthcare system is using wireless sensor modules embedded with NLM-128 algorithm. In addition, PS-LFSR technique is applied to the NLM-128 algorithm to enable faster and more efficient computation. We included some performance statistical results in term of CPU cycles spent on NLM-128 algorithm with and without the PS-LFSR optimization for performance evaluation.

With mobile computing, wireless sensor network and sensor technologies, ubiquitous computing services are being realized and could satisfy the feasibility of ubiquitous healthcare to everyone. This u-Healthcare service can improve life quality of human since medical service can be provided to anyone, anytime, and anywhere. To confirm the vision of u-Healthcare service, we've implemented a healthcare system for heart disease patient which is composed of two components. Front-end collects various signals such as temperature, blood pressure, SpO2, and electrocardiogram, etc. As a backend, medical information server accumulates sensing data and performs back-end processing. To simply transfer these sensing values to a medical team may be too trivial. So, we've designed a model based on context awareness for more improved medical service which is based on artificial neural network. Through rigid experiments, we could confirm that the proposed system can provide improved medical service.

유비쿼터스의 핵심 기술인 RFID는 무선으로 사물을 인식하는 이점 때문에 많은 분야에서 적용되고 있다. 특히 위치추적 및 효율적인 자원관리가 가능하여 사용자의 건강과 관련된 헬스케어 서비스 시스템에서의 활용에 많은 연구가 진행되고 있다. 현재 RFID를 이용한 헬스케어 시스템에서는 사용자의 신상정보 및 사용자의 상태정보, 처방전등 민감한 의료 정보가 시스템의 무선 통신과정에서 사용된다. 하지만 환자의 신상정보와 처방전 같은 무선 통신과정의 정보는 공격자에 의해서 쉽게 도청가능하기 때문에 사용자의 프라이버시 침해가 발생할 수 있다. 본 논문에서는 기존에 제안된 RFID를 이용한 헬스케어 시스템에 대해 살펴보고 RFID를 이용한 헬스케어 시스템에서 발생하는 보안상의 문제점과 프라이버시 침해 문제점에 대하여 지적하고 그에 대한 해결방안을 제시한다.

개인의 삶의 질과 관련되어 건강과 가장 밀접한 관계가 있는 헬스케어 서비스 분야에서 유비쿼터스 비즈니스 모델의 개발이 활발히 이루어지고 있다. 최근 서구화된 식생활과 고령화로 암, 당뇨, 고혈압 등 만성 질환과 노인성 질환이 우리나라에서도 증가하고 있다. 단순히 혈액 중의 당이 높은 것만으로는 즉각적인 증상을 보이지 않는다. 하지만 당뇨병으로 인한 심각한 합병증이 발생할 수 있으므로 당뇨병의 치료 및 예방이 중요하다. 따라서 본 논문에서는 유비쿼터스의 핵심 기술 중 하나인 RFID를 이용하여 당뇨병 환자들의 혈당 및 혈압을 모니터링 하고 식사, 운동, 인슐린 등을 조절하는 헬스케어 서비스 시스템을 구현한다

The threats to privacy and security have received increasing attention as ubiquitous healthcare applications over the Internet become more prevalent, mobile and universal. In particular, we address the communication security issues of access sharing of health information resources in the ubiquitous healthcare environment. The proposed scheme resolves the sender and data authentication problem in information systems and group communications. We propose a novel key management scheme for generating and distributing cryptographic keys to constituent users to provide form of data encryption method for certain types of data concerning resource constraints for secure communications in the ubiquitous healthcare domains.

With the advancement of ubiquitous computing technology, u-Healthcare (i.e. ubiquitous health care), is regarded as a key application for information society, which provides health management service at anytime in anywhere. To implement U-Healthcare system, it is essential to monitor stable biological information in daily life. In this paper, we proposed a small size, light weight, patch type real time temperature monitoring system based on wireless sensor network (WSN) technology to monitor patients' body temperature without any inconvenience of activity.
