This study identifies technical barriers and trends on Radio Frequency Identification(RFID) applications for military force, and investigates technical requirements for the RFID implementation on military information systems, based on the preliminary research results from the introductory RFID applications on Ammunition Information System(AIS). We first obtain technical requirements using the Quality Function Deployment(QFD) methods, and identify the areas for research and developments. Furthermore, based on the survey results from military experts and users, we provide the potential application areas for military RFID implementation. Conversely, a technology and research roadmap for RFID in the military system is developed.

유비쿼터스 컴퓨팅은 무수히 많은 센서들이 관련 데이터 처리 시스템들과 또는 센서들 간의 정보 공유를 통해 서비스를 제공하면서 특정한 장치나 위치에 구애받지 않고 사용자들이 서비스를 이용할 수 있도록 해 준다. 이 논문에서는 유비쿼터스 환경하에서 현재 가장 활발하게 활용되고 있는 RFID(Radio Frequency IDentification) 시스템이 지니는 문제점을 정의하고 이를 극복할 수 있는 새로운 RFID 시스템 구조를 제안한다. 현재의 RFID 시스템은 특정 분야에만 한정하여 단순히 미리 주어진 태그의 식별자를 통해 대상을 식별하는 응용만으로 그 활용성이 제한되어 있다. 이 논문에서는 이러한 제한된 현재의 RFID 시스템의 문제점을 해결하고 유비쿼터스 환경에 적합한 활용성을 극대화할 수 있는 MDR(Metadata registry) 기반의 RFID 시스템 구조를 제안한다. 제안된 시스템은 특정 응용 분야에 종속되지 않고 다양한 분야와의 원활한 연계성을 제공한다. 또한 새로운 정보의 의미를 동적으로 처리할 수 있기 때문에 보다 넓은 응용 범위를 제공한다.

In this paper, we introduce a RFIDbased real time air cargo monitoring system for cargo management in the air cargo terminal. In order to construct functional requirement and development framework,. we have analyzed the user requirements of cargo personnel of Incheon International Air Cargo Terminal. To find out the possibilities to adopt RFID in the cargo, we had benchmarked different RFID systems and also tested radio environment of the cargo. Based on the RFID system test and radior environment test, we developed a web based cargo monitoring solution which adopts EPC network and BPM solution with flexibility and expandability.

RFID(Radio Frequency IDentification) is a technology that automatically identifies objects attached with electronic tags by using radio wave. For the implementation of an RFID system, an anti-collision algorithm is required to identify several tags within the RFID reader's range. Few researches report the performance trade-off among anti-collision algorithms in terms of the communications traffic between the reader and tags, the identification speed, and so on. In this paper, we analyze both tree based memoryless algorithms and slot aloha based algorithms that comprise of almost every class of existing anti-collision algorithms. To compare the performance, we evaluated each class of anti-collision algorithms with respect to low-cost RFID system with 96-bit EPC(Electronic Product Code). The results show that the collision tracking tree algorithm outperforms current tree based and aloha based algorithms by at least 2 times to 50 times.

RFID has been used as an identification tool that substitutes for bar codes. Its areas of application are increasing due to its suitability in ubiquitous environment. In this paper, first, we review various aspects of RFID, including standards, characteristics, and relationships with wireless sensor networks. Then, we review the technical aspects of RFID and its areas of application, e.g., supply chain management (SCM) and manufacturing since 2005. SCM, in which RFIDs can shorten lead time and ensure the quality of products, is one of the most active application areas. Manufacturing is a relatively new area for RFID applications, but it is believed that it can enhance the productivity and the reliability of the products. Also, the authors suggest research issues and limitations of RFID, as well as possible application areas related to marine engineering.

Barcodes have been widely used to implement automatic identification systems but there are various problems such as security weakness or distance restriction in scanning barcode signals in a barcode-based automatic identifcation systems. Recently researchers are gradually interested in radio frequency identification (RFID) and RFID systems have been applied to various fields than before. Especially one of RFID application fields, a bank system uses RFID tagged bankontes to prevent illegal transactions such as counterfeiting banknotes and money laundering. In this paper, we propose a RFID system for protecting location provacy of a banknote holder. In addition, our paper describes that a trust party can trace a counterfeit banknote holder to provide against emergencies.

RFID(Radio Frequency Identification) system is an automated identification system that consists of tags and readers. They communicate with each other by RF signal. As a reader can identify many tags in contactless manner using RF signal, RFID system is expected to do a new technology to substitute a bar-code system. But RFID system creates new threats to the security and privacy of individuals, Because tags and readers communicate with each other in insecure channel using RF signal. So many people are trying to study various manners to solve privacy problems against attacks, but it is difficult to apply to RFID system based on low-cost Gen2. Therefore, We will propose a new encryption scheme using matrix based on Gen2 in RFID system in paper, and We will analyze our encryption scheme in view of the security and efficiency through a simulation and investigate application environments to use our encryption scheme.

RFID (Radio Frequency IDentification) is a wireless frequency recognition technology that can be used to recognize, trace, and Identify people, things and animals using radio frequency. Although current RFID technology can provide wide advantages in many fields, most companies do not consider widely adopting this technology yet. This paper presents RFID implementation as a technology innovation. This research selects three affecting factors of IT infrastructure, fitness of Tag, fitness of Frequency, and one moderator of the power of business partners, on RFID adoption based on innovation model, and then empirical survey is conducted among the companies using RFID technology or planing for RFID adoption to investigate the relationship of three affacting factors and one moderator factor. Reserachers can find the direction to activate RFID technology as a competitive advantage.

Radio Frequency Identification (RFID) is a common term for technologies using micro chips that are able to communicate over short-range radio and that can be used for identifying physical objects. RFID technology already has several application areas and more are being envisioned all the time. While it has the potential of becoming a really ubiquitous part of the information society over time, there are many security and privacy concerns related to RFID that need to be solved. This paper proposes a method which could protect private information and ensure RFID's identification effectively storing face feature information on RFID tag. This method improved linear discriminant analysis has reduced the dimension of feature information which has large size of data. Therefore, face feature information can be stored in small memory field of RFID tag. The proposed algorithm in comparison with other previous methods shows better stability and elevated detection rate and also can be applied to the entrance control management system, digital identification card and others.

One of the ubiquitous technology fields that have received the most attention recently from technology communities worldwide is mobile radio frequency identification (RFID). Mobile handsets loaded with RFID readers enable the identification and retrieval of information on RFID tagged objects. In Korea, a variety of mobile RFID services are currently being piloted, and their commercial roll-out looks imminent. The goal of this study is to propose, ahead of the commercial launch of mobile RFID services, a customer satisfaction index (CSI) model for this service category and to then measure the CSI to derive practical implications for their providers and pointers related to the improvement of service. A web survey was conducted on Korean mobile phone subscribers who had participated in a mobile RFID pilot program. Using the results of this survey, we tested the CSI model and its hypotheses by employing a partial least-squares-based structural equation model analysis and calculated the index. We further conducted an importance-performance analysis in order to provide insights that may be useful for improving the quality of mobile RFID services.
