최근 u-헬스케어 서비스는 바이오센서 및 스마트 의료 기기의 발달과 의료 데이터의 교환 및 처리를 위한 표준 기술 등이 뒷받침 되면서 서비스의 실체화가 가속화되고 있는 추세이다. u-헬스케어는 유 무선 네트워크와 밀접한 연관을 맺고 있으며, 이러한 유 무선 네트워크의 사용은 기존의 서비스에서 발생 가능한 보안상의 취약점 및 공격이 u-헬스케어 환경에서도 유사하게 나타나며, 개인 의료정보를 주로 다루는 만큼 그 위험성은 더욱 심각하다 사료된다. 이에 본 논문에서는 u-헬스케어의 보안 위협 및 그에 따른 향후 대책방안에 대하여 논하고자 한다.

최근 인터넷의 급성장에 따라 유 무선 네트워크 기반의 다양한 서비스들이 소개되고 서비스 되고 있다. 그 중에서도 사용자의 건강과 관련된 서비스가 헬스케어 서비스이다. 특히, 모바일 단말기 보급과 더불어 건강에 대한 관심은 모바일 헬스케어 서비스에 대한 연구를 촉진시키고 있는 실정이다. 따라서 본 연구에서는 기존의 모바일 헬스케어 서비스에서 보안적 취약점을 분석하고 홈 네트워크 환경에서 모바일 헬스케어 서비스를 제공한 경우 요구되는 보안적인 요구사항을 제시하여 홈 네트워크 기반의 안전한 모바일 헬스케어 서비스를 제안하고자 한다.

Now a days, U-healthcare comes into the spotlight as a new business model which combines RFID technology with medical service in the well-being era and IT popularization. U-healthcare service needs a method that can deals with hand-writing, overlap data, forgery and falsification of data, difference between information version that happen in medical process because of graft between RFID technology and u-healthcare. This paper proposes RFID based user certification protocol to protect user's privacy who gets medical service through U-healthcare. In the protocol, secret information of patient does the XOR with the secret key that is created in the hospital to reconsider the stability of security system of U-healthcare and user's data forgery and falsification and privacy and then saves it in the secret key field of patient in DB table. Also, it informs the case of illegal access to certification server and make it approved the access of u-healthcare service by differentiating whether u-healthcare is illegal or not.

All medical information system stakeholders and the environment exists. Medical information systems for development in these environments and non-functional requirements, functional requirements and quality goals are to be met. In order to achieve these goals in a variety of ways currently being made to develop information systems and various applications are emerging. However, the process of developing these health information systems meet the basic requirements and does not consider that from the point of view should not be separate. This study of the development of health information systems related to quality measurement indicators for the analysis software architectures, and medical information, information quality evaluation of service quality information associated indicators evaluation are offered. This way of associated indicators for the quality of the output sum and analyze the trends in software architecture u-Healthcare should be available for assessment. Quality score compared with pre-set goals for achievement and satisfaction levels of analysis further support the cause excerpt field use in analysis and improvement is possible.

According to the rapid population aging and the increase of the number of people with chronic diseases, the digital healthcare services are getting more and more attention. Recent improvement in information technology has expanded the consumers of digital healthcare service from the patients to the general population. Therefore, there is a growing need for studies on the status and needs of digital healthcare users in general. This study conducted a survey of 1,000 people on their perception and attitude about four areas of digital healthcare: internet health information service, smartphone healthcare application, wearable device, and u-health. The questionnaire asked the respondents about their past experience of using digital healthcare services, the purpose of use and point to be improved. The respondents were also asked about new type and contents of digital healthcare service which they would like to use. The survey results will help developers of digital healthcare service by improving their understanding and identifying unmet needs from the general population.

The aging population and the advancement of science and technology are transforming the healthcare industry to focus on health management for the prevention of diseases. The U-health and remote healthcare services have not yet achieved the social agreement in the nation; however, these have been extensively used in the global scale. The innovation of user experience through cognitive computing are expected to increase the health effects of consumers, by converging with healthcare information services. This study suggests the conceptual model of healthcare information service converged with cognitive computing. Then, the acceptance factors for consumers have been investigated. For this purpose, reliability and validity analysis have been conducted using an online survey. The path analysis was performed to verify the hypotheses and moderating effect based upon the gender, by using structural equation modeling.

한국 사회의 인구 고령화 속도는 세계 최고 수준으로 향후 보건, 의료, 복지 등에서 심각한 사회 문제를 발생시킬 것으로 예상되고, 고령화 사회로 인한 질병 발생률의 증가는 국민 의료비 부담의 증가로 이어져 이에 대한 대책이 필요하다. 이에 따라, 정보통신기술을 이용하여 시간과 공간에 구애받지 않고 언제 어디서나 건강과 생활을 관리하여 건강한 삶을 유지시키는 새로운 형태의 서비스인 유헬스케어(u-Healthcare)가 많은 주목을 받고 있다. 최근에는 일반인, 고령자, 만성질환자를 대상으로 하는 유헬스케어용 건강 개인 기기의 개발이 확산되고 있으나, 표준이 없이 업체별로 제품개발이 이루어지기 때문에 서비스간 호환성 등의 문제가 생기고, 이로 인해 유헬스케어 산업의 성장에 장애요소로 작용하고 있다. 이를 해결하기 위해, 최근 헬스케어 분야의 표준화가 활발하게 진행되고 있으며, 표준화를 통해 생체정보 데이터의 취합 및 전송, 분석 및 피드백이 표준적인 방법으로 운용이 될 수 있도록 하고 개인 건강 기기들과 유헬스케어 서비스간의 상호 운용성이 보장이 될 수 있도록 할 수 있다. 본 고에서는 최근 헬스케어 분야에서 가장 활발하게 표준화가 진행중인 IEEE 11073 PHD 표준화 동향과 HL7 CDA의 표준화 동향에 대해서 상세히 살펴보고, 본 연구원에서 개발한 국제 표준기반 유헬스케어 플랫폼에 대한 소개를 한다.

Hospital medical services are making great efforts to provide prompt medical services to patients or improve the quality of medical services by convergence patient's healthcare information. However, recent research suggests problems about safety and efficiency when trying to transmit patient's healthcare information to hospital server via radio and wireless. In this paper, we propose a color model - based patient authentication key establishment protocol method to securely transmit patient healthcare information. The proposed method extracts randomly three color information used in the color model and vectorizes the extracted arbitrary information to obtain the key information required for user authentication as the sum of orthogonal vectors to improve the efficiency. In addition, the proposed method can securely generate key information used for user authentication without using an additional encryption algorithm. In performance evaluation result, proposed method shows that the server processing time of the sensed information is 8.1% higher than the existing method and 7.7% lower than the existing method.

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.
