The use of Radio Frequency Identification technology (RFID) in medical context enables not only drug identification, but also a rapid and precise identification of patients, physicians, nurses or any other healthcare giver. The combination of RFID tag identification with structured and secured Internet of Things (IoT) solutions enables ubiquitous and easy access to medical related records, while providing control and security to all interactions. This paper defines a basic security architecture, easily deployable on mobile platforms, which would allow to establish and manage a medication prescription service in mobility context making use of electronic Personal Health Records. This security architecture is aimed to be used with a mobile e-health application (m-health) through a simple and intuitive interface, supported by RFID technology. This architecture, able to support secured and authenticated interactions, will enable an easy deployment of m-health applications. The special case of drug administration and ubiquitous medication control system, along with the corresponding Internet of Things context, is presented.

With the development of the Internet, user authentication technology that proves me online is improving. Existing ID methods pose a threat of personal information leakage if the service provider manages personal information and security is weak, and the information subject is to the service provider. In this study, as online identification technology develops, we propose a DID-based self-authentication model to prevent the threat of leakage of personal information from a centralized format and strengthen sovereignty. The proposed model allows users to directly manage personal information and strengthen their sovereignty over information topics through VC issued by the issuing agency. As a research method, a self-authentication model that guarantees security and integrity is presented using a decentralized identifier method based on distributed ledger technology, and the security of the attack method is analyzed. Because it authenticates through DID Auth using public key encryption algorithms, it is safe from sniffing, man in the middle attack, and the proposed model can replace real identity card.

As IoT Technology develops and Era of Hyperconnectivity comes, various kinds of customized services became available. As a next-generation display, a smart mirror accesses multimedia devices and provides various services, so it can serve as a social learning tool for the children and the old ones, as well as adults who need information. Smart Mirror must be able to identify users for individualized services. However, since the Smart Mirror is an easily accessible device, there is a possibility that information such as an individual's pattern and habit stored in the smart mirror may be exposed to the outside. Also, the other possibility of leakage of personal location information is through personal schedule or appointment stored in the smart mirror, and another possibility that privacy can be violated is through checking the health state via personal photographs. In this research, we propose a system that identify users by the information the users registered about their physique just like their face, one that provides individually customized service to users after identifying them, and one which provides minimal information and service for unauthenticated users.

In this paper, we present an optimal hardware implementation for preprocessing of a person identification algorithm utilizing vein pattern of dorsal surface of hand. For the vein pattern recognition, the computational burden of the algorithm lies mainly in the preprocessing of the input images, especially in lowpass filtering. we could reduce the identification time to one tenth by hardware design of the lowpass filter compared to sequential computations. In terms of the computation accuracy, the simulation results show that the CSD code provided an optimized coefficient value with about 91.62% accuracy in comparison with the floating point implementation of current coefficient value of the lowpass filter. The post-simulation of a VHDL model has been performed by using the ModelSim$^{TM}$. The implemented chip operates at 20MHz and has the operational speed of 55.107㎳.㎳.

국내 전자상거래 제품과의 호환성과 확장성을 위하여 국내 전자서명 표준인 KCDSA(Korean Certificate-based Digital Signature Algorithm) 메커니즘을 PKCS(Public Key Cryptographic Standard) #11 암호 API(Application Programming Interface)에 기능을 추가한다. PKCS #11에서 정의한 키 관리(Hey Management) 함수의 입력 파라미터에 암호화할 키를 바로 입력하면 변조된 키를 전달할 수 있으므로, 본 논문에서는 안전한 키보호(Key Protection) 함수를 새로 정의하여 암호화할 키 대신 사용자 PIN(Personal Identification Number: 패스워드) 입력하여 사용자의 KCDSA 개인키와 공개키를 보다 더 안전하게 보관하고자 한다.

This is to improve the complicate process of the existing CD copy flow in Department of Radiology. It is also to improve the medical service of the hospital to secure private information of patients. Survey: The patients who ask for CD copies in the Department of Radiology of this hospital(for 6 months in 2010). Time: Comparing the total amount of time of the previous and the modified CD copy flow. Using the SPSS 12.0 program for testing significance of independent two-samples t-test. Private information: Introducing the identification-system based on the medical law to supplement the security of personal information of patients. There was manifold complaints due to receipt and issuing the prescription in Admission and Discharging office and outpatient department. The time has been approximately 50% reduced from 70 mistunes to 32 mistunes due to simplifying the routes. The security of the personal information has been supplemented by let patients submit documentary evidence based on the medical law. The service in the hospital has been improved as a result of simplifying the whole process of the routes and receipt process. Therefore, the each stage of waiting time has been decreased. In addition, the personal information of the patients has been more secured.

Decentralized SSI(Self Sovereign Identity) has become an alternative to a new digital identity solution, but an efficient de-identification technique has not been proposed due to the unique algorithmic characteristics of data transactions. In this study, to ensure the decentralized operation of SSI, we propose a de-identification technique that does not remove identifiers by restructuring the verification results of ZKP (Zero Knowledge Proof) into a form that can be provided to the outside by the verifier. In addition, it is possible to provide restructured de-identification data without the consent of data subject by proposing the concept of differential sovereignty management for each entity participating in verification. As a result, the proposed model satisfies the domestic personal information protection law in a decnetralized SSI, in addition provides secure and efficient de-identification processing and sovereignty management.

The electronic transactions over the Internet are growing across the world recently. There have been a lot of identity theft incidents during these online transactions nowaday. Therefore, a high level of identity proofing shall be carried out when using online services to deal with these matter. To prevent this kind of incident, i-PIN was introduced in Korea, which is used as an Internet Personal Identification Number. The i-PIN is designated to provide an online identification of the Internet users. As such, the unique identification numbers are provided to the internet service providers. This paper is to analyze the capabilities that the i-PIN provides, to propose the assurance security model for i-PIN. Furthermore, the security analysis results are presented. The result of this paper can be applicable to improve the applicabilities of the i-PIN.

In this study, a model in which certification standards were added to the health information management practice program was studied and presented in order to understand the EMR certification standards implemented by the Korea Health and Medical Information Service. In the practice program, the certification standard function for patient information management was added to the health information management education system to practice and understand patient information management that corresponds to the functional standard of the EMR certification system. The EMR certification standard practice program for patient information management is composed of the following certification standards. registration number and personal information management, treatment reservation schedule management, personal information revision history management, identification of people with the same name, integrated management of multiple registration numbers, patient search by identification information, patient search by health care type, surgical procedure consent record and inquiry, record/inquiry of consent form for personal information use, display of life-sustaining medical decision information, registration/inquiry of external medical institution documents, registration and inquiry of external examination results. In this way, by operating and practicing the functions of the health information system according to the certification standards, it is possible to understand and practice the certification standards and details of patient information management in the functional area of the certification standards. In addition, since the function of the EMR certification standard can be checked, it will be possible to improve the management ability of the electronic medical record system of the health information manager in the medical institution.
