u-Healthcare는 의료 장비 및 센서 등을 이용하여 획득된 생체 신호 및 의료정보를 유 무선의 통신수단을 통해 지식 기반의 의료정보로 구축하고 이를 언제, 어디서, 누구든지 이용 가능한 실시간 u-Healthcare 지원 환경을 구축하여 지능형 의료정보 웹 포털 서비스를 제공하는데 목적을 두고 있는 서비스이다. 하지만 현시점에서의 시스템은 생체 신호 및 의료 정보 제공시에 보안에 대한 고려가 이루어지고 있지 않다. 이러한 자원들은 개인 프라이버시에 직결되는 것으로 보안의 필요성이 대두된다. 따라서 본 논문에서는 IP망에서 생체신호 전송을 위한 전송시스템을 설계하고 전송시 생체신호정보에 대해 사용자 인증과 암호화를 적용하여 u-Healthcare 전송시스템을 설계하고 구현하였다.

U-Healthcare는 언제 어디서나 환자의 생체 건강을 관리하고 유지할 수 있도록 하는 정보통신기술이다. U-Healthcare통신은 대부분 무선통신을 사용하여 검진 결과나 위급 시에 감지된 환자의 정보를 병원 서버로 전송한다. 이 때 U-Healthcare기기나 병원 서버에 악의적인 행위자가 DDoS공격을 하면 환자의 정보는 병원서버까지 전송되지 못해 병원의 도움을 받을 수 없는 상황이 발생된다. 이에 대응하기 위하여 본 논문은 U-Healthcare 통신 공격 패턴과 시나리오를 빅데이터로 구축한다. 그 후 악의적인 사용자가 U-Healthcare기기나 서버를 공격하면 DB와 연동하여 일치된 공격을 막을 수 있다. 앞으로 원격의료 서비스에서 나타날 수 있는 보안 위협을 알아보고, 빅데이터를 활용하여 보안 위협에 대응할 수 있는 방법을 제안한다.

U-Healthcare 서비스는 차세대 의료 패러다임으로 많은 이용자에게 편의성을 보장하기 때문에 사회에서 그 중요성이 인식되고 상용화 시도가 이루어지고 있다. 이러한 U-Healthcae 서비스 시장이 안전하게 형성되기 위해서는 정부의 보안정책이 확실하게 정립되어야 한다. 본 고에서는 안전한 U-Healthcare 서비스의 보안위협을 보안의 3대 요소인 기밀성, 무결성, 가용성을 기준으로 분류하고 살펴본 후 이에 대한 보안정책 방향을 제시하고자 한다.

The existing patient monitoring system when the patient want own information. The patient confirm information through the medical institution. But the patient monitoring system based on the U-Healthcare, the patient always confirms own information through the mobile device including rfid reader. The patient need RFID middleware design to provide wanting service when the RFID reader read patient's tag information. The RFID middleware is consisted of RFID module, ARM processor and RS-232 interface. The RFID module is used to be inputted user information and RS-232 interface pass information by RFID middleware. Also, This system is embodied by specific patient monitoring system using embedded exclusive use ARM processor. In this paper introduces concept and action principle of RFID middleware and embodied patient monitoring system that use Qt.

There are already many researches providing u-Healthcare service, but they have left problems to be improved. First of all, the transmission range between sensor nodes and the gateway are restricted. Hence, patients feel uncomfortable because of they need to possess or locate closed to a gateway all the time when they aggregates their medical data. Also, the existing systems have not considered life environment that is important to analyze patient's diseases. Moreover, a guardian need to located close to patient or possess a mobile device that monitors a patients' status in real time when they are in outdoor. In this research, we present multi-hop packet transfer algorithm and compilation of life environment which help improve the problem of the existing researches. Likewise, we designed and implemented a medical information database and a real-time web monitoring system that manage patients' personal history and monitor a patients' status in real time. In this paper, we design and implement the u-Healthcare system based on mobile environment and we present a result when we tested our u-Healthcare system in scenario environment.

최근 Wellness 산업과 스마트 디바이스가 융합되면서 기존의 질병관리 체계보다 앞서 예방하는 건강관리 u-Healthcare 가 개발되고 있다. 하지만 u-Healthcare 에서 취급되는 개인정보 및 의료정보는 메시지 탈취/변조로 인해 공격자에게 악용되어 의료사고를 유발하고 환자의 생명까지 앗아갈 수 있으며 또한 프라이버시 침해로 인해 사용자의 신변을 보장 받을 수 없다. 본 논문에서는 웰니스 서비스의 u-Healthcare 보안의 고려사항과 연구동향에 대해 살펴보고 현재 u-Healthcare 분야에서 보안이 적용된 시스템에 대해 분석하고 취급되는 정보보호의 중요성에 대해 고찰한다.

In this paper, we propose the active model based on the distributed object group framework which provides adaptive information sharing service to support it to various Healthcare home service. And we applied it to Healthcare home service. This proposed model provides information that collected from physical environment of the home network and sensors for healthcare service according to situation of the user. We uses information of the healthcare information database which was constructed previously, and we uses TMO scheme for to solve each other different periodic qualify. We uses information of the healthcare information database which was constructed previously, and we uses TMO scheme for to solve each other different periodic quality. Specialty, We wrote about interaction of various Healthcare Home services for adaptive information services, and wrote about u-healthcare framework based on DOGF. Finally, we apply active model to healthcare monitoring service, and we showed its result and performance evaluation.

Recently, the RFID technology is combined with a u-healthcare services is an emerging trend in the field of medical services. u-healthcare service, as covering the field of personal health information beyond the level of simple health screening and treatment of life are closely related. Considering security, invasion of privacy, as well as life may be threatened even if your personal health information to be exposed or exploited illegally u-Healthcare services certification is essential. In 2012, Jeong proposed J-L patient authentication protocol that Initialization process, and patients using RFID technology separates the certification process. Jeong, such as the claim that the proposed protocol for reuse attacks, spoofing attacks, prevent information disclosure and traceability fire safety, but raises issues of security and operations efficiency. Therefore, in this paper, Jeong, such as the security of the proposed protocol and to prove the computational efficiency issues, and to enhance the safety and efficiency of RFID technology based on practical u-Healthcare services authentication protocol is proposed.

As changed the clinical environment, the interest on u-Healthcare service and systems has been increased. The ubiquitous healthcare(u-Healthcare) systems are constructed at the integrated environment that consists of various devices and systems basically such as personal health devices(PHDs) measuring body signals, information aggregators gathering the data transmitted from PHDs through wireless technology, and health information systems storing and managing personal health information transmitted from the information aggregators. International standards such as IEEE 11073 and HL7 have been specified for the interoperability of PHDs and health information systems, but the research on u-Healthcare systems that were developed and applied in the real clinical environment by adopting the standards was rarely conducted. Therefore, we developed an u-Healthcare system which can manage personal health information, such as blood glucose, blood pressure, and body composition, based on health information exchange standards. Moreover, we verified the stability of the developed system through clinical trial in patients with endocrine disease at the Kyungpook National University Hospital, and listed problems occurred during clinical trial and found their solutions.
