In this paper, a USB module with fingerprint recognition was designed as a distributed node of blockchain on distributed ID (DID, distributed ID) for user identification. This biometric-linked fingerprint recognition device was verified for the real-time authentication process of authentication transaction with FIDO(Fast IDentity Online) server. Blockchain DID-based services were proposed like as a method of individual TV rating survey, and recommending service for customized shopping channels, and crypto-currency, too. This DID based remote service can be improved by recognizing of channel-changing information through personal identification. The proposed information of production purchase can be shared by blockchain. And customized service can be provided for the utilization of purchase history in shoppingmall using distributed ID. As a result, this blockchain node-device and Samsung S10 Key-srore with FIDO service can be certified for additional transactions through various biometric authentication like fingerprint, and face recognition.

E-BLP security model considers the reliability of the processes that are real subjects in systems. This paper deals with the implementation of the E-BLP model for secure embedded systems. Implemented EBSM(E-BLP Based Security Module) consists of three components: identification and authentication, access control and BRC(Dynamic Reliability Check) that checks the process behavior dynamically. Access Control of EBSM ensures unreliable processes not to access the sensitive objects and the DRC detects the buffer overflow attack by normal user. Besides, the performance overhead of the embedded system applying the EBSM is introduced.

Ubiquitous environment is constructed by development of an IT technology, offer environment of many service changed to mobile environment. Also, existed service offered at fixed position like home or company, but according to development of mobile device. user require service as moving. Wibro can offer as user moving using mobile device. As requirement should be included authentication, in case of authentication between UICC and AAA authentication server is offered in Wibro, service is available. However, when UICC requires initial authentication to AAA authentication server, identification information of UICC expose as plaintext, so privacy infringement of mobile device occurs. Therefore, identification information of terminal generate randomly using OTP(One-Time Password) that generated in mobile terminal, and we proposed mechanism of privacy protection. Also, we proposed mechanism that offer secure service to user as offer authentication from OTP framework, and offer OTP combination authentication detailedly.

This paper describes how to protect the personal information of a biometric reference provider wherein biometric reference and personally identifiable information are bounded in a biometric system. To overcome the shortcomings of the simple personal authentication method using a password, such as identify theft, a biometric system that utilizes physical and behavioral characteristics of each person is usually adopted. In the biometric system, the biometric information itself is personal information, and it can be used as an unique identifier that can identify a particular individual when combining with the other information. As a result, secure protection methods are required for generating, storing, and transmitting biometric information. Considering these issues, this paper proposes a method for ensuring confidentiality and integrity in storing and transferring personally identifiable information that is used in conjunction with biometric information, by extending the related X9.84 standard. This paper also outlines the usefulness of the proposition by defining a standard format represented by ASN.1, and implementing it.

사회구조가 복잡해질수록 보안(Security)의 확보는 점차 중요한 사회문제로 대두되고 있다. 보안의 문제에서 가장 중요한 것이 각 개인의 본인 여부를 정확하고 신속하게 판별할 수 있는 자동화된 인증(Authentication) 기술의 개발 여부라고 할 수 있다. 이를 위해 사용되는 개인식별은 신체의 일부를 이용한 지문인식, 두개골함성, 장문인식, 족적인식, 입술인식, 홍채인식, 골격인식 등 불변하는 신체의 특징을 이용하는 연구가 주도적이었다. 본 연구에서는 개인식별에 관한 총체적인 영상시스템을 위한 영상처리 자료를 정리한다.

Electronic identity (e-ID) card based on smartcard is a representative identity credential for on-line and off-line personal identification. The e-ID card can store the personal identity information securely, so that the information can be accessed fast, automated identity verification and used to determine the cardholder's authorization to access protected resources. Due to such features of an e-ID card, the number of government organizations and corporate enterprises that consider using e-ID card for identity management is increasing. In this paper, we present an authentication framework for access control system using e-ID cards by discussing the threat environment and security requirement against e-ID card. Specifically, to accomplish our purpose, we consider the Personal Identity Verification system as our target model.

Each online user should perform a separate registration and manage his ID and password for each online commerce or SNS service. Since a common secret is shared between the user and the SNS server, the server compromise induces the user privacy breach and financial loss. In this paper, it is considered that the user's authentication material is shared between multiple SNS servers for user authentication. A blockchain service architecture based on Hyperledger Fabric is proposed for each user to utilize an identical ID and OTP using the enhanced hash-chain-based OTP.

최근들어 Radio Frequency Identification(RFID) 태그가 다수의 상품에 부착되고 여러 분야에 적용되기 시작했지만, 편리성이나 비용문제로 인해 인증과 암호화 같은 보안기능은 적용되지 않고있다. 보안 기능이 없는 RFID 시스템은 개인정보 노출, 불법 리더의 접근, 위조 태그의 남용과 같은 심각한 부작용을 초래하지만, 태그 자원의 제약으로 인해 보안기능을 적용하기가 쉽지않다. 현재 여러 기술을 따르는 RFID 시스템 중 EPCglobal 의 EPC Class 1 Generation 2(C1G2) 는 산업계의 여러 분야에서 특히, supply-chain 모델에서 사실상 국제표준으로 여겨진다. 본 논문에서는, RFID 보안 프로토콜 중 EPC C1G2 메커니즘의 Inventory 과정에서 태그가 리더를 인증하는 기법을 제안한다. C1G2 시스템에서는 인증되지 않은 리더의 태그 액세스가 가능한데, 이는 태그의 리더 인증으로서 차단될 수 있다. 또한, EPC C1G2 태그-리더 간의 상호인증 기법을 제안한다. 이 과정에서 태그 ID 는 노출되지 않고 전송되며, 태그 인증을 통해 태그 위변조를 방지할 수도 있다. 제안 메커니즘은 태그를 식별하는 절차에서 인증을 위해 프로토콜 패스 수의 증가가 없다. 다만 리더와 태그에서 Inventory 과정의 ACK command 와 태그의 reply 구현에 약간의 수정을 필요로 한다.

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.
