환자상황 기반의 자동인증시스템 구축 및 성능평가 = Implementation of An Automatic Authentication System Based on Patient’s Situations and Its Performance Evaluation

다국어 초록 (Multilingual Abstract)

In the current medical information system, a system environment is constructed in which Biometric data generated by using IoT or medical equipment connected to a patient can be stored in a medical information server and monitored at the same time. Also, the patient's biometric data, medical information, and personal information after simple authentication using only the ID / PW via the mobile terminal of the medical staff are easily accessible. However, the method of accessing these medical information needs to be improved in the dimension of protecting patient's personal information, and provides a quick authentication system for first aid. In this paper, we implemented an automatic authentication system based on the patient's situation and evaluated its performance. Patient‘s situation was graded into normal and emergency situation, and the situation of the patient was determined in real time using incoming patient biometric data from the ward. If the patient's situation is an emergency, an emergency message including an emergency code is send to the mobile terminal of the medical staff, and they attempted automatic authentication to access the upper medical information of the patient. Automatic authentication is a combination of user authentication(ID/PW, emergency code) and mobile terminal authentication(medical staff’s role, working hours, work location). After user authentication, mobile terminal authentication is proceeded automatically without additional intervention by medical staff. After completing all authentications, medical staffs get authorization according to the role of medical staffs and patient's situations, and can access to the patient's graded medical information and personal information through the mobile terminal. We protected the patient's medical information through limited medical information access by the medical staff according to the patient's situation, and provided an automatic authentication without additional intervention in an emergency situation. We performed performance evaluation to verify the performance of the implemented automatic authentication system.

현 의료정보시스템에서는 환자에게 부착된 IoT 또는 의료기기를 통해 생성된 생체데이터를 의료정보서버에 저장과 동시에 모니터링 할 수 있는 시스템 환경이 구축되고 있다. 또한 의료진의 이동단말기를 통해 ID/PW만을 이용한 간단한 인증 후 환자의 생체데이터및 의료정보, 개인정보에 쉽게 접근이 용이하다. 그러나 이러한 의료정보 접근방법은 환자 개인정보보호차원에서 개선되어야하며, 응급처치를 위한 신속한 인증시스템이 제공되어야 한다. 이에 본 논문에서는 환자상황기반의 자동인증시스템을 구축 및 성능평가 하였다. 환자상황을 정상상황과 응급상황으로 분류하고, 병동으로부터 들어오는 환자 생체데이터를 이용하여 환자상황을 실시간으로 판별하였다. 환자상황이 응급상황일 경우 의료진의 이동단말기에 응급코드를 포함한 응급메시지가 수신되고, 의료진은 환자 상위의료정보를 확인하기 위해 애플리케이션을 통해 자동인증을 시도한다. 자동인증은 사용자인증(ID/PW, 응급코드)과 이동단말기인증(의료진역할, 근무시간, 근무위치)이 결합된 인증방법으로써 사용자인증 이후 의료진의 추가개입 없이 자동으로 이동단말기인증이 진행된다. 모든인증을 마친 의료진은 의료진 역할과 환자상황에 따라 접근권한을 부여받고, 애플리케이션을 통해 환자의 등급화 된 의료정보에 접근이 가능하도록 구현하였다. 환자상황에 따른 의료진의 제한적 의료정보접근을 통해 환자의 의료정보를 보호하고, 응급상황 시 추가개입 없는 자동인증을 구현하여 신속한 인증을 제공하였다. 구현된 자동인증시스템의 수행성 검증을 위해 성능평가를 실시하였다
