This paper describes an Security Manager that integrally manages the Information Service related to RFID middleware, Object Name Service, and Web Service for upper level applications. In order to provide the access control of distributed RFID objects, Single-Sign-On has been implemented by extending existing UCON (Usage Control) model and SAML (Security Assertion Markup Language) assertions. The security technology of distributed RFID systems can be included in middleware and protect RFID information. In the future, it can be also applied to ubiquitous sensor networks.

MIT의 Auto-ID 센터가 주관하고 Wal-Mart, Gillette, Unilever, Pepsi 등 세계 50여개 유통 및 제조회사가 참여 한 RFID (radio frequency identification system) 공동연구 프로젝트는 "물건들의 인터넷" 을 구축하려고 노력하고 있다. RFID는 전파식별기술로서 전자태그(tag)를 상품에 부착하여, 상품이 주위 안테나를 인지하고 기존 IT 시스템과 실시간으로 정보교환 및 처리가 가능한 기술이다. 이 분야의 선두주자인 Wal-Mart는 134개의 주요 협력회사에게 2005년 1월부터 RFID 태그를 부착하여 납품하도록 요구하고 있다. 본 글에서는 RFID기술과 응용사례에 대하여 소개하고, RFID의 발전이 품질 및 고객안전성 향상에 어떻게 활용될 수 있는지 살펴보려고 한다.

With the application enlargement of RFID technology in the field of logistics, it is needed to analyze the relation adoption factors of RFID with logistics performance. That is, this study aims at analyzing how RFID adoption would give an effect to logistics performance in logistics company, stating its implications. More specifically, this study tests empirical relation of CEO's support, technical competence, trading partner, compatibility, relative advantage and logistics performance of applying RFID in logistics company. Based on previous studies which are related to RFID in the field of SCM, logistics, distribution and manufacturing, this study established research model and hypothesis, and surveyed employees of logistics company. To analyze the data, exploratory factor analysis, reliability analysis, confirmatory factor analysis and structural equation model were applied. The results are follows. Applying RFID in logistics, CEO's support and trading partner gives significantly positive effect to logistics performance. But compatibility and relative advantage do not give meaningful effect to logistics performance. Additionally, though technical competence does not have statistical significance to logistics performance, it is necessary to consider it can have meaningful influence on logistics performance substantially.

In this study, a customized semi-passive RFID receiver module was implemented for in-VIVO deep tissue photo-therapy. A novel wireless technique is required due to a limitation of RF communication in body environment, as internal body has a complex structure such as, skin, fat, skeleton, water, and so on. Recently, coherently incoherent beamforming (CIB) based on RFID was introduced and it is able to transmit wireless signal with high reliability under the incoherent condition such as in-VIVO deep tissue. The proposed miniature photo capsule based on RFID consists of miniature controller, ultra small LED array and wireless RFID chip. RF Reader can access with standard RFID protocol (ISO 18000-6c) using UHF RFID antenna, a control command is wirelessly writtern on USER Bank memory. With received control command, therapy LED array dims with mulilevel under timer control. The signal process of designed RFID photo therapy capsule is analyzed and evaluated under the various environments in detailed.

RFID(Radio Frequency IDentification) is a technology that automatically identifies objects containing the electronic tags by using radio wave. When there are some tags in the domain of the RFID reader, the mechanism that can solve a collision between the tags occurs is necessary. The multi tag identification problem is the core issue in the RFID and could be resolved by the anti-collision algorithm. However, RFID system has another problem. The problem id user information security. Tag response easily by query of reader, so the system happened user privacy violent problem by tag information exposure. In the case, RFID system id weak from sniffing by outside. In this paper, We study of security robustness for tree-walking algorithm, query tree algorithm and advanced query tree algorithm of tree based memoryless algorithm.

The RFID Technology (which is importantly used at the Ubiquitous environment) is attached to all of the units like the ID cards and then information on the units and units' environment is transferred and processed through the radio frequency. so it is the no touched recognition system. RFID Technology's research of the middle ware and wireless interface etc. is currently conducted and variously broaden like the industry of the distribution and logistics. This paper suggests that the gate control system which is based on RFID middle ware is realized to prevent the district and facility for security. The indication of this paper is that algorithm (which is to certificate Users' enterance through RFID EPC code) is proposed and realizes the user certification module, the control module of the gates' opening and closing, the maintenance module of the gate, the display module of coming and going information, test program ect. through RFID technology.

With the advent of ubiquitous society, the paradigm of education is also changing. In u-learning in ubiquitous environment, mobile devices such as cellular phone, PDA, PMP, UMPC and TPC will become important learning tools. Particularly if RFID, a key technology in ubiquitous society, is utilized in teaching-learning along with mobile devices, we can expect much more meaningful learning. The present study proposed four types of application of RFID to teaching.learning, which were RFID-card, RFID-book, RFID-label and RFID-test, and examined their possibility and effectiveness. According to the results of this study, technology was insufficient to support the application of RFID-label to teaching-learning and continuous research was required for modeling the application of RFID to teaching-learning.

RFID(Radio Frequency Identification) is used to describe a system that transmits the identity of an object or person wirelessly using radio waves. RFID is recognized as a key technology of USN(Ubiquitous Sensor Network). ISO/IEC JTC1 and EPCglobal are developing RFID related standards for global supply chain management. RFID is an important solution not only for the supply chain management, but also for USN and future services. Recently, mobile RFID which provide various services using RFID reader in mobile phone, is being standardized in Korea. In this paper, we analyze trends of RFID standardization activities in ISO/IEC JTC1 and EPCglobal and mobile RFID, and propose an convergence scenario of IPv6 and RFID.

In recent years, Item Level RFID market, attaching RFID instead of barcodes to individual units for item rather than box and pallet units, is expected to expand both domestically and internationally in the future. In this study, by analyzing the demand for Item Level RFID services which apply RFID to the individual units, we would like to come by strategies that promote and develop RFID industry. This study consists of the following contents. First, we analyzed trends in domestic and overseas markets of Item Level RFID. Second, we surveyed the RFID demanding companies and analyzed Item Level RFID promising service sector, the expected leading field of market, the leading field of dissemination, and the obstacles of its introduction. Finally, on the basis of the results of the empirical study, we presented the strategies to promote Item Level RFID.
