Guidelines for protecting personal information are already in progress in USA, UK and other countries and announced many guideline like HIPPA. However In Our national environment, we does not have specialized guideline in national medical industries. This thesis suggest De-indentification method in South Korea by referring 'bigdata De-identification Guideline by Ministry of Science, ICT and Future Planning (2015)', ICO in U. K and IHE, NIST, HIPPA in U. S. A. We suggest also correlation between Guidelines. Corelation means common techniques in three guidelines (IHE, NIST, HIPPA in U. S. A). As Point becomes closer five points, We recommend that technique to national medical institute for De-Identification. We hope this thesis makes the best use of personal information's development in National medical institute.

Recently the interest in secondary use of medical information has emerged. But the domestic legislation or guidelines, such as being able to say that already specialize in healthcare information, can be seen a 'national medical privacy guidelines'. However the guidelines have suggested that only a violation of privacy laws in the medical information, it does not defined clearly with respect to protected health information(PHI) for secondary use. In this paper, we learn the HIPAA(Health Insurance Portability and Accountability Act) Privacy Rule of the US legislation which provides a non-identifiable screen instructions for secondary utilization of medical information, domestic guidelines and other country's guidelines. comparing with the HIPAA, national medical privacy guidelines and the domestic studies, we propose a new domestic target non-identifying information suitable for the domestic field and present future research direction.

Recently, the processing and utilization of big data, which is generated by the spread of smartphone, SNS, and the internet of things, is emerging as a new growth engine of ICT field. However, in order to utilize such big data, De-identification of personal information should be done. De-identification removes identifying information from a data set so that individual data cannot be linked with specific individuals. De-identification can reduce the privacy risk associated with collecting, processing, archiving, distributing or publishing information, thus it attempts to balance the contradictory goals of using and sharing personal information while protecting privacy. De-identified information has also been re-identified and has been controversial for the protection of personal information, but the number of instances where personal information such as big data is de-identified and processed is increasing. In addition, many de-identification guidelines have been introduced and a method for de-identification of personal information has been proposed. Therefore, in this study, we describe the big data de-identification process and follow-up management, and then compare and analyze de-identification methods. Finally we provide personal information protection issues and solutions.

The recent frequent cases of damage due to leakage of medical data and the privacy of medical patients is increasing day by day. The government says the Privacy Rule regulations established for these victims, such as prevention. Medical data guidelines can be seen 'national medical privacy guidelines' is only released. When replacing the image data between the institutions it has been included in the image file (JPG, JPEG, TIFF) there is exchange of data in common formats such as being made when the file is leaked to an external file there is a risk that the exposure key identification information of the patient. This medial image file has no protection such as encryption, This this paper, introduces a masking technique using a mosaic technique encrypting the image file contains the application to optical character recognition techniques. We propose pseudonymization technique of personal information in the image data.

In this study, the method of quality measurement for the statistical usefulness of de-identified data was examined in terms of prediction accuracy by statistical modeling. In the era of the 4th industrial revolution, effective use of big data is essential to innovation through information and communication technology, but personal information issues are constrained to actively utilize big data. In order to solve this problem, de-identification guidelines have been established and the possibility of actual re-identification of personal information has become very low due to the utilization of various de-identification methods. On the other hand, strong de-identification can have side effects that degrade the usefulness of the data. We have studied the quality of statistical usefulness of the de-identified data by KLT model which is a representative de-identification method, A case study was conducted to see how statistical accuracy of prediction is degraded by de-identification. We also proposed a new measure of data usefulness of the de-identified data by quantifying how much data is added to the de-identified data to restore the accuracy of the predictive model.

기능 분해는 복잡한 시스템을 이해하기 위해 광범위에게 사용되는 시스템 모델링 기술이다. 기능 분해는 문제 영역을 기능별로 분해하는 데 그 기반을 두고 있으며 , 이는 시스템의 기능에 대한 식별을 전제로 한다. 일반적으로 시스템의 기능에 대한 식별은, 분석가에 의해 어떠한 조직적인 지침없이 비정형적으로 수행되는 것이 관례였다. 따라서 이러한 기법을 이용하면 시스템을 분할하거나 시스템의 기능을 올바르게 식별하기가 매우 어렵다. 본 논문은 이러한 기능 분석에 대해 use case을 이용한 기법을 제안하고자한다. 본 기법의 장점은 크게 두가지로 요약할수 있다. 첫째, 시스템의 분할과 기능에 대한 식별이 전통적인 기법보다 더 용이하다. 둘째, 시스템의 요구사항과 구현이 사용자에 의해 쉽게 검증될 수 있다. 본 기법은 하향식으로 이루어져, 구조적 분석과 같이 보편화된 기능 분석 기법들과 자연스럽게 병합될 수 있다. 본 논문은 이를 위해 use case의 식별, 그리고 이를 이용한 기능 분해를 단계적 과정과 가이드라인을 통해 설명하고, 이를 특정 에플리케이션에 적용하여 그 유용성을 입증한다.

Today's rapidly developing health technology is accumulating vast amounts of data through medical devices based on the Internet of Things in addition to data generated in hospitals. The collected data is a raw material that can create a variety of values, but our society lacks legal and institutional mechanisms to support medical Big Data. Therefore, in this study, we looked at four major factors that hinder the use of medical Big Data to find ways to enhance use of the Big Data based healthcare industry, and also derived implications for expanding domestic medical Big Data by identifying foreign policies and technological trends. As a result of the study, it was concluded that it is necessary to improve the regulatory system that satisfies the security and usability of healthcare Big Data as well as establish Big Data governance. For this, it is proposed to refer to the Big Data De-identification Guidelines adopted by the United States and the United Kingdom to reorganize the regulatory system. In the future, it is expected that it will be necessary to have a study that has measures of the conclusions and implications of this study and to supplement the institutional needs to play a positive role in the use of medical Big Data.

With the development of big data technology, data is rapidly entering a hyperconnected intelligent society that accelerates innovative growth in all industries. The convergence industry, which holds and utilizes various high-quality data, is becoming a new growth engine, and big data is fused to various traditional industries. In particular, in the medical field, structured data such as electronic medical record data and unstructured medical data such as CT and MRI are used together to increase the accuracy of disease prediction and diagnosis. Currently, the importance and size of unstructured data are increasing day by day in the medical industry, but conventional data security technologies and policies are structured data-oriented, and considerations for the security and utilization of unstructured data are insufficient. In order for medical treatment using big data to be activated in the future, data diversity and security must be internalized and organically linked at the stage of data construction, distribution, and utilization. In this paper, the current status of domestic and foreign data security systems and technologies is analyzed. After that, it is proposed to add unstructured data-centered de-identification technology to the guidelines for unstructured data and technology application cases in the industry so that unstructured data can be actively used in the medical field, and to establish standards for judging personal information for unstructured data. Furthermore, an object feature-based identification ID that can be used for unstructured data without infringing on personal information is proposed.

In accordance with the revision of the Data 3 Act, such as the Personal Information Protection Act, it is possible to process pseudonym information without the consent of the information subject for statistical creation, scientific research, and preservation of public records, and unlike personal information, it is legal for personal information leakage notification and personal information destruction There are exceptions. It is necessary to revise the pseudonym information in that the standard for the pseudonym processing differs by country and the identification guidelines and anonymization are identified in the guidelines for non-identification of personal information in Korea. In this paper, we focus on the use of personal information in accordance with the 4th Industrial Revolution, examine the concept of pseudonym information for safe use of newly introduced pseudonym information, and generate / use / provide / destroy domestic and foreign non-identification measures standards and pseudonym information. At this stage, through the review of the main contents of the law or the enforcement ordinance (draft), I would like to make suggestions on future management / technical protection measures.
