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.

Inernet of Things(IoT) is interaction with each other, collecting, sharing, and analysing the data. IoT has been noted in combining the fields of medical service in particular. However, the security issue is caused, while IoT is receiving attention. U-Health and medical devices, which deal mainly the personal health information, is required to a high level of privacy and security of health information. This study analyzes cases of leakage of personal medical information, security of IoT, privacy flow, and the response strategies.

Blockchain technology is a new paradigm that will change existing business processes and has a significant impact on all industries, not just on specific industries. The medical industry also expects the impact of blockchain technology to be very significant. I think blockchain technology should be applied in the medical industry because the medical industry has the problem of information asymmetry due to the structural characteristics of a centralized system composed of hospitals. However, no one can be sure that the value of blockchain technology is absolutely right, and absolute trust should be avoided. Blockchain technology provides many limitations to the process in which blockchain technology is applied in the medical industry, as it can be seen as still immature in terms of security and scalability. Therefore, we analyze the application cases of blockchain technology in the medical field, current problems in the medical field, solutions and issues through Blockchain.

What is an alternative to medical information security of medical information more secure preservation and safety of various types of security threats should be taken, starting from the software design. Interspersed with medical information systems medical information to be able to integrate the real-time exchange of medical information must be reliable data communication. The software architecture design of medical information systems and sharing of medical information security issues and communication phase allows the user to identify the requirements reflected in the software design. Software framework design, message standard design, design a web-based inter-process communication procedures, access control algorithm design, architecture, writing descriptions, evaluation of various will procedure the establishing architecture. The initial decision is a software architecture design, development, testing, maintenance, ongoing impact. In addition, the project will be based on the decision in detail. Medical information security method based on the design software architecture of today's medical information security has become an important task of the framework will be able to provide.

Recently, as the technology has been blended with IT, BT or NT and technology in each field has been developed progressively with the people's needs for a healthy and abundance life. In the medical service field as well, related technologies such as medical equipment, medical information system, or medical business application have come to be diversified and advanced. However, most of these medical technologies are being developed independently without an interaction with other medical institutions or related companies, which causes many problems in the integration or interchangeability of them. This paper is intended to solve the problems generated during a direct information sharing between the functional interfaces of the present healthcare information sharing system. This paper develops a repository between the interfaces, which can save all the healthcare information from the institutions, and convert and publish it in various forms of document. In other words, recently HL7 protocol has been used for sharing the healthcare information in order to save the information in XML format, and develops the H-DISS(Healthcare-Documents Integrated Sharing System), a repository to manage and publish the saved document.

As smart devices and communication technologies have developed rapidly, the healthcare industry in the globe is seeing remarkable issues on medical security. At the same time, personal medical records are being shared in the network, which would raise the risk of information security. This thesis aims to develop the curriculum to raise the awareness of information security among workers in medical institutions by referring to NCS(National Competency Standards) International standards, medical institutions' requirements and educational institutions' curriculums on information security based on proven results from medical devices and systems introduced in the public health centers, territorial branches, community health posts and primary, secondary, tertiary hospitals. Thus, this thesis offers the method to improve information security in healthcare institutions through validation testing conducted by medical practitioners and ICT experts.

DICOM (Digital Imaging and Communications in Medicine) standards are generally introduced as de facto and de jure standards in modern medical imaging devices to store and to transmit medical image information. DICOM Dose Structured Report (DICOM dose SR) is implemented to report radiation exposure information in image acquiring process. and DIOCM Modality Performed Procedure Step (DICOM MPPS) is also partly used to report this exposure with the information in its DICOM tag. This article is focused on three type of radiation exposure information of DICOM standards, 1) DICOM dose SR, 2) DICOM MPPS and 3) Radiation Exposure Monitoring(REM) profile by Integrating the Healthcare Enterprise(IHE), to study on radiation exposure reporting. Healthcare facility and its staff of medical imaging related to radiation exposure should have a deep understanding of radiation exposure, and it required a standards to enhance the quality control of medical imaging and the safety of patients and staffs. Staff member have to pay attention on radiation exposures and controling processes from the purchasing stage of X-ray devices.

The purpose of this study was to design and implement a useful annotation-based Radiological image retrieval system to accurately determine on education and image information for Radiological technologists. For better retrieval performance based on large image databases, we presented an indexing technique that integrated $B^+-tree$ proposed by Bayer for indexing simple attributes and inverted file structure for text medical keywords acquired from additional description information about Radiological images. In our results, we implemented proposed retrieval system with Delphi under Windows XP environment. End users, Radiological technologists, are able to store simple attributes information such as doctor name, operator name, body parts, disease and so on, additional text-based description information, and Radiological image itself as well as to retrieve wanted results by using simple attributes and text keywords from large image databases by graphic user interface. Consequently proposed system can be used for effective clinical decision on Radiological image, reduction of education time by organizing the knowledge, and well organized education in the clinical fields. In addition, It can be expected to develop as decision support system by constructing web-based integrated imaging system included general image and special contrast image for the future.

인터넷의 보급과 네트웍기술의 발달은 실생활과 사회 전반에 걸쳐 많은 변화를 가져오고 있고 시공간에 제작이 많았던 의료분야 역시 이러한 변화를 적극 수용하여 다양한 양질의 서비스를 제공하고자 노력하고 있다. 본 논문에서는 단순한 의료정보 제공 및 건강 상담 차원을 넘어 고혈압이나 당뇨 같이 지속적으로 의사 관찰이 필요한 만성질환의 진료를 지원하는 새로운 형태의 의료 사이트가 제시되어 있다. 환자 자신은 건강 상태를 스스로 관리하고 그 정보를 주치의와 공유함으로서 의사는 온라인 상에서도 환자를 항상 모니터링할 수 있고 특정 전문 분야에 관련된 회사들간 네트워크를 구현하여 새로운 의학 정보 공유 및 상호 컨설팅이 가능하고 공유된 전문 정보를 바탕으로 지역별로 환자가 의료혜택을 고르게 받을 수 있도록 유도하고 있다. 구축한 사이트는 전문적인 정보제공 이외에도 그래프가 포함된 전자차트 기능과 의사소통의 한계성을 극복하고 의료 상담의 정확성을 기하기 위한 동영상 게시판 등 멀티미디어 기능을 강화시켰다.
