  • 본 논문에서는 ZigBee 기반의 u-health 환경에서 센서노드가 고유한 식별 값을 기반으로 통신을 하기 때문에 발생될 수 있는 프라이버시 침해의 가능성이 있으므로 임시 ID를 사용하여 통신하는 프로토콜을 설계하여 제안한다. u-health 환경은 인체에서 측정된 생체신호를 센서노드가 게이트웨이 디바이스로 전송하는 ZigBee 통신 구간이 가장 취약한 부분이다. 그리고 개인의 생체신호 데이터는 의료정보로 분류될 수 있는 민감한 정보로서 보호가 필요하여 본 논문에서 해당 구간의 취약점을 보완하는 프로토콜을 제안한다.

  • This study suggests focused in user-centered design which are new separate discharge system that must recycle in paper materials. I searched cases in Korea's current law and regulation in recycling disposal guidelines and already succeed cases in each city that are Asia, Europe, and North America. Suggesting focused in user-centered design of ID(Identification) separate discharge system due to user's good participations, feedbacks of participation's results, and well-organized in awarding. This system consists of visual individual's ID(Identification) that are stickered in only used bag. User must recycle in separate discharge system only used bags, and results must visualized in each user and rewards to user. This separate discharge system is meaning to stimulate user's good participations.

  • A EAARS(Electronic Attendance-Absence Recording System) is the important LSS(Learning Support System) for blending a on-line learning in the face-to-face classroom. However, the EAARS based on the smart card can not identify a real owner of the checked card. Therefore, we develop the CS(Client-Sever) system that manages the attendance-absence checking automatically, which is used the self-organizing neural network for the face recognition. A client system creates the ID file by extracting the face feature, a server system analyzes the ID file sent from client system, and performs a student identification by using the Recognized weight file saved in Database. As a result, The proposed CS EAARS shows the 92% efficiency in the CS environment that includes the various face image database of the real classroom.

  • We introduce a personal identification method which can find user's ID without any help of the user. To do this, there has been two approaches, vision-based and pressure-based. Pressure-based approach has some advantages compared than vision-based one in the aspects of illumination, occlusion, and the amount of data. In the previous study about pressure-based personal identification, there are some restrictions about human body posture for extracting normalized footprints. Since this approach cannot be extended unconscious and continuos identification, we suppose more natural method and verified it by experiments.

  • RFID 태그의 사용에 있어서 사용자 개인의 프라이버시 문제(위치정보 또는 구매이력 노출 등)을 심각하게 인식하여야 하며 RFID 태그의 ID는 쉽게 식별되며 태그는 사용자가 알지 못하는 사이에 모든 리더에게 자동적으로 응답한다. 이러한 우려들이 RFID의 상용화에 걸림돌이 되며 성공적인 산업화를 위해서는 제반 프라이버시 문제를 해결해야 하는 것이 선결 과제로 되고 있다.

  • 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.

A Mechanism of CAS Client Personalization through separating CAS Service of Protocol A.1 on TTA.KO-07.0079 XCAS (TTA.KO-07.0079 XCAS 프로토콜 A.1의 CAS 서비스 분리를 통한 CAS Client 개인화 메커니즘)

  • CAS Client personalization means to issue CAS ID or Key for CAS service, which is Core Technology for CAS operation. Protocol A.1 on TTA.KR-07.0079 XCAS, stores CAS Client personalization data from CAS server in XCAS server, and transmits the personalization data by request of XCAS HOST for CAS Client personalization. However, this may increase Network Traffic and CAS Client image management in XCAS server. In this thesis, to complement this, CAS Client personalization is executed on CAS Server by separating CAS service field. Therefore this can distribute Image management and Network Traffic of XCAS server.

  • Currently, the user authentication technology used by users to access multiple applications within an organization is being applied with ID/PW-based SSO technology. These user authentication methods have the fundamental disadvantages of ID/PW and SSO. This means that security vulnerabilities in ID/PW can lead to periodic changes in PWs and limits on the number of incorrect PW inputs, and SSO adds high cost of the SSO server, which centrally stores the authentication information, etc. There is also a fundamental vulnerability that allows others to freely use other people's applications when they leave the portal application screen with SSO. In this paper, we proposed an app-based 2-channel authentication scheme to fundamentally eliminate problems with existing ID/PW-based SSO user authentication technologies. To this end, it distributed centralized user authentication information that is stored on SSO server to each individual's smartphone. In addition, when users access a particular application, they are required to be authenticated through their own smartphone apps.

  • To provide medical services to patients who have a terminal illness, recent hospital patients to monitor the state of the device attached to the body, the body insertion device is. U-Healthcare Environment and hospital officials indiscriminately exploited by the patient's vital information, however, could threaten the patient's life problems are appearing. In this paper, depending on the level of authority, hospital officials, Union of ID-based authentication model is proposed to use a patient's vital information. Union proposed model identify different authentication system is used in hospitals that exist in various forms in a number of ID information, health / medical information sharing between hospitals without exposure to unnecessary personal information, you can be assured of the anonymity. In particular, with easy access to patient information, hospital officials about the malicious act to protect patient information to access level for the rights granted by third parties to prevent easy access.

  • Biometrics is a study of identifying individual by using the features of human body. It has been studied for an alternative or complementary method for the classical method based on password, ID card, etc. In comparison with the fingerprint, iris, ear, palmprint, finger-knuckle print has been recently studied. This paper proposes an effective method for recognizing finger-knuckle print based on the feature of Gradient orientation. The main features of finger-knuckle print are the size and direction of winkles. In order to extract these features stably, we make a feature vector consisted of Gradient orientations after the preprocessing of enhancing non-uniform brightness and low contrast. Total 790 images acquired from 158 persons have been used at the experiment for evaluating the performance of the proposed method. The experimental results show the recognition rate of 99.69% and the relatively high decidability index of 1.882. These results demonstrate that the proposed method is effective in recognizing finger-knuckle print.
