Medical records are very important records and should not be modified after creation. The current medical records are liable to improper modification. With the development of information technology, electronic medical records (EMR) are used widely. For the EMR, cryptographic primitives may be used to develop techniques to prevent medical record modofication. In this research, a technique to prevent improper medical record prevention is proposed. It uses crytographic primitives such as linked hash, digital signature, and electronic notarization. A prototype system is also developed for performance analysis. The proposed method makes the medical record modification impossible with a small amount of additional cost.

One of the most secure ways of maintaining the confidentiality and integrity of electronic information is to use electronic signatures. So, in this paper, we developed guideline on electronic signatures for EMR(electronic medical record) based on the Medical Law and the Electronic Signature Act. This guideline is intended to introduce EMR easily in the medical field and to facilitate the promotion of EMR. We developed it through consulting from the advisory committee that was made up of experts in the fields of medical record, EMR system and electronic signatures. The contents of the guideline consist of subject and time stamp of electronic signatures, validity of a certificate, management of electronic signatures and custody and management of EMR. In the future, we will develop practical cases and promote educations and publicities of them to use in the medical institutes and EMR system related industries.

In recent years, two major streams in medical information systems are：1) system integration among OCS(Order Communication System), EMR(Electronic Medical Record), PACS(Picture Archiving and Communication System), and ERP(Enterprise Resource Planning) and 2) system integration through medical collaboration between East and West medical service providers. One of the characteristics which differentiate the Korean medical industry from the western medical industry is the East-West medical collaboration. In many respects there are many differences between East and West medical treatment. Although East and West medical treatment have developed from different medical philosophies and standards, we assume that the better medical care can be provided by integrating their medical procedures effectively. The two possible approaches to the integration of East and West medical information systems are suggested in this paper：One is loosely coupled model and the other is tightly coupled model. EMR improves the quality of medical record which reflects the quality of clinical practice. It provides more efficient and convenient way of input, retrieval, storage, communication and management of medical data. We abstracted the standard medical procedures from the two medical procedures performed in Daejeon Oriental Hospital and Hehwa Clinic at Daejeon University and also abstracted database schema by analyzing the characteristics of information needed in East-West medical collaboration. Our EMR is composed of two types of data：one is structured data and the other is unstructured data, which are formalized by SOAP(Subjective, Objective, Assessment, Plan) format. Currently the integrated system is implemented and operated successfully for six months.

Due to the development of Internet and the collection and usage of the individual information, the infringements of the personal data have been increased rapidly. Regarding the personal data protection in the medical industry, it is clearly described in 'Act on Promotion of Information and Communication Network Utilization and information Protection, etc.'. the law is ratified on the basis of the service provider, therefore, it has its own limitation to be applied to medical industry. Therefore, this paper is to set the security standard and to discuss the range of legal application and considerations on its basis for the domestic medical institution at the electronic medical record system. We exemplify specific applicable content of the electronic signature in the electronic medical record also, present a security assessment item in electronic medical system and set the criteria for the security standard in the medical industry.

Today, data subjects should be considered to utilize various personal data. To support this paradigm, the concept of "My Data" has proposed and has realized in various industrial sectors, including medial sectors. Based on the concept of the medical My Data, this paper proposes a personal health record (PHR) and an electronic medical record (EMR) data trading model. Particularly, this paper proposes a system model to support the medical My Data environment and relevant procedure among stakeholders for PHR/EMR data trading that ensures the rights of data subjects. Based on the proposed system model, this paper also proposes various mathematical models to analyze the behavior of stakeholders and shows the feasibility of the proposed data trading model that satisfies the requirements of both data subjects and data consumers.

The Electronic Medical Record (EMR) is a valuable source of medical data intelligence in e-health systems. The watermarking techniques have been used to authenticate the owner and protect the EMR from illegal copying. The existing distributive strategies, successfully operated to secure the EMR, are found to be inadequate. Blockchain technology, mainly, is employed by a sharing database that allows the digital crypto-currency. It rapidly leads to the magnified expectations acme. In this excitement, the use of consortium adopting the technology based on Blockchain, in the EMR structure, is found improving. This type of consortium adds an immutable share with a translucent record of the entire business and it is accomplished with responsibility, along with faith and transparency. The combination of watermarking and Blockchain technology provides a singular chance to promote a secured, trustworthy electronic documents administration to share with the e-records system. The authors, in this article, present their views on consortium Blockchain technology which is incorporated in the EMR system. The ledger, used for the distribution of the block structure, has team healthcare models based on dissimilar multiple image watermarking techniques.

EMR(Electronic Medical Record) is being broadly used in general medical institution, but it could be more efficient and convenient if patients could use it themselves. Because present EMR is the formula written by medical experts with professional words, the patient can not identify his detailed symptoms and even the name of disease. Otherwise, the patient should have many efforts for obtaining his medical records. To solve this problem, this study developed Patient-Accessible EMR system, which was founded as one of patient-centric medical services, and it shows that the patient can take his medical information without medical experts.

The purpose of this research which was conducted by surveying the transfer consultation records from 360 medical institutions such as general hospitals, hospitals, clinics to the Emergency Medical Center at E University Hospital for six months(Jan. 1, 2000 - Jun. 30, 2000) are to standardize & complete transfer consultation record of hospitals at the 1st & 2nd referral level and to give patients transferred emergency medical center medical information services on a better quality. The conclusions and suggestions from this study were summarized as follows; (1) Examing the distribution of the referral medical consultation(transfer) sheet type, surgery part local clinic sheet types were 34.4%, medical part local clinic sheet types were 26.7%, undifferentiated local clinic sheet types were 23.9% and hospital level sheet types were 15.0%. (2) The items of the transfer consultation records had been standardized more than 75% in the order of patient's name, date, doctor's name, diagnosis, patient's status, impressions. (3) That the degree of recording completion on these items is in the order of patient's name, date, diagnosis, impressions was revealed. (4) Because the standardization and the degree of recording completion are very low in the patient's gender, age, address, electronic recording system was needed for more perfect input of initial patient informations. (5) This standardizing & complete recording on examination and medication will prevent re-examination and abuse of medication for patients transferred emergency medical center. (6) EMT Transfer System should be fixed in all medical institute for the standardizing & complete recording on care period and departure time will give many emergency patients the proper treatments at the proper time. (7) It was revealed that developing new standardized transfer consultation record & using electronic recording system are needed. (8) The complete recording & Fast Track System were needed for higher rate of bed operation at emergency medical center and more hospital profit.

Currently, different medical institutions have been carrying out the e-healthcare system project. The system includes electronic medical record and prescription delivery system, and, the Medical Treatment law permits electronic signature for medical record management, which reduced the relevant costs and enabled sharing medical record. And medical solution using online certificates is expanding its application. In that light, the role of certificates became more important than ever. However, in contrast to active effort made to manage personal certificates, certificates related to medical solutions and other types of work are not being managed properly. Most work-related certificates are saved in office computers, which makes them vulnerable to various security threats. Although certificate servers can be used as a solution to this problem, hospitals must build the server separately and, therefore, small and medium-size hospitals can be reluctant to bear the burden. This study proposed a way to design and implement an effective and secure certificate management system by save the certificate file as a BLOB, using existing resources without needing to build a separate certificate server, at minimized costs.

Most of electronic medical record systems which have been built in Korean hospitals are based on source oriented medical record approach. These systems hardly satisfy diverse objectives owing to the innate imperfections in system architecture and development methodology. Thus, the hybrid of source oriented and problem oriented approach is highly desirable. The purpose of this study is to present an architecture and methodology required to construct hybrid electronic medical record system and to develop a prototype based on them. Analyzing the clinical processes and data requirements of problem oriented medical record approach we developed a software process model as weel as an architecture model which consists of legacy system, clinical data repository, problem list database, prospective plan database, user interface, and synchronization procedures.
