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.

Currently, many computer systems are used in many areas of medicine including radiation oncology. For the most part, the computer system has proved to be useful in radiotherapeutic planning and dose calculation. There has been attempts to develop computer system including information management of patients, patient tracing, and office automation in radiation oncology department. But some of these available commercial systems have shortcomings. We developed a management system of patients in our radiation oncology department that integrated most of items for the evaluation of patents. In particular, the data were stored in a natural language (noncoded) and made themselves easily understandable by all clinical groups. In addition , the data could be isolated in files from which the computer could generate graphs and static data by the use of some simple commands. The system provided us with not only the functions of case review but functions of preparation of conferences, lectures and resident teaching.

최근에 우리 사회는 불규칙적인 식습관, 부족한 운동, 과도한 스트레스 등으로 만성질환 및 성인병 환자가 늘어나는 심각성이 날로 커지고 있다. 성인병의 심각성은 40대 이상에서 크게 대두 되었던 과거와 달리, 최근에는 20대를 넘어서서 10대 청소년에게까지 성인병을 앓고 있는 환자들이 날로 많아지고 있다. 세계적으로 IT가 크게 발달함에 따라 병원과 환자가 서로 만나지 않아도 24시간 소통이 되는 u-Healthcare 시스템이 크게 대두되고 있다. 이에 따라서 환자 개개인과 주치의가 시 공간에 제약받지 않고 상호 긴밀하게 진료, 검사 및 피드백이 가능하게 된다. 본 연구진은 u-Healthcare 시스템에 부합하고 스마트 폰을 이용하여 만성질환자를 관리할 수 있는 u-DailyCare 시스템을 설계하고 구현하였다. 스마트 폰 사용자로부터 얻어진 생체 정보 데이터 및 행위 데이터들을 수집하여 서버에 보내면, 주치의는 종합된 전체적인 데이터를 실시간으로 확인하여 환자의 상태를 검토 및 진단하여 피드백을 준다. 본 논문에서는 u-DailyCare 시스템의 설계 및 구현과정을 설명할 것이다.

ularly, a points of view Health-care system, it can reduce costs and efforts in order to management of patients. However, Health-care system keep a level of service for person and extends of hospital inner parts system. Although the rate of an addict grow by alcoholic but it is difficult to manage and diagnosis because of patient data gathering. Therefore in this thesis, it is proposed to patient data gathering and monitering method in u-zone. It can collect patient data by pulse, temperature and acceleration sensor and it can diagnosis correct based on emotion change data.

The aim of the research is that disease database of the glycosuria and heart's blood is designed to manage the condition of the glycosuria and heart's blood patients periodically and continuously. Also we integrate patient database of existing OCS, PACS, EMR, ERP etc. and support optimal service timely that the patients want through intelligent integrated interface environment. For this, we will develop customized medical information convergence system. We construct intelligent database for disease of the glycosuria and heart's blood. And we support data integration environment for connection with existing systems - OCS, EMR, PACS etc. Also, in consideration of QoS, reliability, and expandability of customized medical information convergence system, we will design H/W, S/W, and data compatibility method.

Recently invasion of privacy problem in medical information have been issued following the interest in secondary use of large medical information. These large medical information is very useful information that can be used in various fields such as disease research and prevention. However, due to the privacy laws such as Privacy Act and Medical Law, these informations including patients or health professionals' personal information are difficult to utilize secondary. Accordingly, various methods such as k-anonymity, l-diversity and differential-privacy that can be utilized while protecting privacy have been developed and utilized in this field. In this paper, we study differential privacy processing procedure, one of various methods, and find out about the differential privacy problem using Laplace noise. Finally, we propose a new method using the Shamir's secret sharing method and symemetric key encryption algorithm such as AES for this problem.

Nowadays, telemedicine and remote prescription has been operating as a pilot basis. However, in case of remote hospitals without encrypting the biometric data transmission and its contents, the patient prescription data hacked from hackers who changed prescription medications can be serious obstacles to the patient. Therefore, in this paper, to solve this problem, password encryption, personal identification information, biometric data security on the patient's prescription and remote medical information system, and implementation of the encryption algorithm are proposed.

This paper is for the a study on home healthcare system for a patient using SAW Tag. This system is useful when there's a patient in home. Many patients are wounded in restroom. But restroom is very private place and nobody want to be disturbed here. The place where the patient is most injured in the house is the toilet, and it is the point where the privacy of the individual should be kept and the patient's condition should be checked and cope with in case of emergency. And using saw tag, we can calculate position and ID through reflected rf signal. Therefore we propose a general home healthcare system. The management system utilized a seat bed system to monitor at-home patients. The system mounts a bio-signal measuring unit on a toilet seat, measures a bio-signal from the bio-signal measuring unit, and the measured bio-signal is transmitted to the main server through the user's smart phone. With proposed system, we can expand operation area to silver town where many patients are cared. In this paper we developed sensor system and saw tag positioning system and showed the result.

본 논문은 추론 공격 가능성 범위를 확장하여 다수 제공자의 참여를 기반으로 개인에 관한 정보를 배포하는 환경에서의 추론공격 가능성을 고려한다. 환경의 특성상 참여자는 자신이 보유한 환자 데이터와 외부지식을 결합하여 개인의 민감한 정보를 추론할 수 있다. 또한 기존의 추론공격을 방지하는 익명화 기법은 다수 제공자 환경을 고려하지 않기 때문에 추가적인 추론 공격이 가능하다. 본 논문은 제공자에 의한 추론 공격을 보이고 이를 방지하는 기법으로 s-cohesion을 제안한다.

Patients' privacy protection is a heated issue in medical business, as medical information in digital format transmit everywhere through networks without any limitation. A current protection method for brain images is to deface from the brain image for patient's privacy. However, the defacing process often removes important brain voxels so that the defaced brain image is damaged for medical analysis. An ad-hoc method is proposed to conceal patient's identification by adding cylindrical mask, while the brain keep all important brain voxels. The proposed lossless deformation of brain image is verified not to loose any important voxels. Futhermore, the masked brain image is proved not to be recognized by others.
