RFID (Radio Frequency IDentification) 기술은 개별 사물을 빠르고 정확하게 식별하는 것을 가능하게 한다. 이러한 RFID를 이용한 자동식별 기술은 다양한 응용분야에서 일부분만 적용되던 것이 점차적으로 비즈니스 프로세스 상의 다수의 활동에 걸쳐 적용되고 있다. 그로인해 이와 연계된 RFID 시스템은 각각의 RFID 장비들의 물리적 인식으로 인한 오류뿐만 아니라 전체 프로세스 상의 흐름과 연결되어 정보가 단절되거나 불일치로 인한 오류가 발생하게 된다. 이러한 오류들은 RFID 시스템의 신뢰성을 저하시키기 때문에 이를 미리 식별할 수 있는 방법이 필요하다. 본 논문에서는 RFID 시스템의 신뢰성 향상을 위하여 개발 전 미리 확인되어져야 하는 태그인식 요구사항을 분석하고 이를 명시적으로 모델링하는 방법을 제안한다. 이는 다양한 상황에서 발생할 수 있는 RFID 시스템의 각 유형별 오류들을 예측하는 과정을 통해 도출된다. 태그인식 요구사항을 식별하여 이를 개발 또는 실행 시 확인하도록 함으로써 비즈니스 프로세스 과정 중, RFID 태그흐름을 통해 발생할 수 있는 오류들을 사전에 예측하고 예방할 수 있게 되어, 그 결과 RFID 시스템의 신뢰도를 높여주게 된다.

RFID (Radio Frequency Identification) is the technology to quickly and accurately identify an object using a radio frequency transmission. Automatic identification technologies such as RFID were only a partial solution to the problem, but these have evolved into many other uses throughout many activities in business processes. The various errors in an RFID system may be occurred by the physical reading of RFID equipments, and by an inconsistency between data processing seamlessly on processes. These errors tend to cause the RFID system with a lower reliability. In this paper, we suggest a method for analyzing and modeling tag-identification requirements, which should be identified before developing the system, to improve reliability of the RFID system. These can be identified using methods for predicting various errors types in the RFID system. If the tag-identification requirements are identified and analyzed preferentially, these many errors can be prevented. Finally, the RFID system is promised with higher reliability.

세계 각국은 새로운 유비쿼터스 환경변화에 맞추어 전략적 차원에서 u-IT에 대한 연구와 다양한 프로젝트를 추진 중이다. 그 중 지역수준에서 u-정보화의 편익을 체감 할 수 있고, 지역산업 발전에도 기여할 수 있는 u-City 서비스 모델들을 발굴하여 집 중적으로 추진함으로써 지역 구성원들간 삶의 질을 제고하고 관련 산업의 성장을 도 모하고 있다. 그러나 유비쿼터스 환경의 중심 기술 중 하나인 RFID 기술은 다양한 기술적용환경과 표준화되지 않은 일부 기술들로 인하여, u-City 사업의 기대효과를 부 각시키지 못함은 물론 실제 지속적인 서비스모델로 적용하기도 쉽지 않은 상황이다. 따라서 본 연구에서는 기존의 문제점을 보완하여 새로운 u-City 서비스 모델로써 u-Zone 서비스 구축시에 필요한 듀얼밴드를 적용한 RFID 시스템의 소프트웨어 모듈과 OID개념을 도입한 데이터 프로토콜 표준적용에 관한 연구 방안을 모색하고자 한다.

Spotlighted as an innovative information technology environment, ubiquitous computing has been actively researched on recently. Especially, domestic and global researches focus on the RFID system, which is being eyed to replace the existing bar-code system. As an essential technology for ubiquitous computing, the RFID system can be applied for various purposes. The security issues of the RFID system focus on how the low-priced tag type could have reasonable price competitiveness. The Auto-ID Center in the U.S. is spearheading the research on distribution service and omni-directional security. As for Japan, the researches on omni-directional security and EPC application are necessary in securing the technology for ubiquitous computing with support from the Ministry of Public Management Home Affairs, Posts, and Telecommunication. In this paper, a method of ensuring the availability of the RFID system service will be presented based on the ubiquitous computing environment with the existing omni-directional security and user-friendly interface. While the existing researches focus on the RF reader system and tag-based security, this paper's suggestion also considers the availability of a sen ice to suggest ways of increasing the practical usage of a low-priced RF tag.

RFID is a widely adopted in the field of identification technology these days. Radio Frequency IDentification (RFID) has wide applications in many areas including manufacturing, healthcare, and transportation. Because limited resource RFID tags are used, various risks could threaten their abilities to provide essential services to users. A number of RFID protocols have done by researcher in order to protect against some malicious attacks and threat. Existing RFID protocols are able to resolve a number of security and privacy issues, but still unable to overcome other security & privacy related issues. In this paper, we analyses security schemes and vulnerability in RFID application. Considering this RFID security issues, we survey the security threats and open problems related to issues by means of information security and privacy. Neither a symmetric nor an asymmetric cryptographic deployment is necessarily used with light weighted algorithm in the future.

Despite their various similarities, Seoul's' Gangnam and Seocho districts showed different patterns in the adoption of the RFID household-based waste charging system. Gangnam, one of the 25 wealthiest districts in Seoul, first adopted the RFID system in 2012, but decided abandon it a year later due to inconvenience, sanitation, budget limitations, and management related issues. Unlike Gangnam, Seocho, a largely similar district to Gangnam, started to implement the RFID system in 2015 and successfully adopted this innovation. In this paper, we explain the adoption behaviors of these two districts using a Technology Hype Curve Model with 5 stages. Unlike traditional technology adoption theory, the Hype Curve Model concentrates on the big chasm between early majorities and late majorities, which is a core reason for discontinuity in innovation diffusion. Based on our case study result, the early majority easily gave up adoption due to immature technological and institutional infrastructure. However, Seocho district, who waited until the deficiencies had been sufficiently fixed since late majorities, succeeded at incremental diffusion. Since its invention by Gartner cooperation, the Hype Curve Model has not received enough attention in academia. This paper demonstrates its explanatory power for innovation diffusion. Similarly, this paper focuses on the importance of institutional framework in the diffusion of innovation. Lastly, we compare the behavior of two local governments in supporting and diffusing RFID systems to draw relevant policy implications for innovation diffusion.

The wireless sensor networking standard DASH7 operates in low-power communication with a better transmission quality in active RFID networks. The DASH7 security standard supports public key cryptography. At present, the DASH7 standard uses the message authentication code in the network layer for authentication and integrity. However, its security standard is still in an incubation stage with respect to the implementation of a crypto exchange over a DASH7 network. Effective key management is an important factor for privacy and security. If organizations are not careful about where and how keys are stored, they leave the encrypted data vulnerable to theft. In this regard, we present a key management system designed for efficient key management through public key infrastructure authentication as well as a non-repudiation feature for the DASH7 standard. We analyze the performance of the proposed system on a basis of various performance criteria such as latency and throughput.

유비쿼터스 기술을 활용한 U-city와 같은 지역적인 서비스들이 다양한 분야에서 응용되고 있다. 유비쿼터스 기술 중 하나인 RFID는 사용하는 주파수에 따라 장 단점을 가지고 있기 때문에 단일 대역 주파수를 활용한 RFID 시스템은 다양해지는 사용자의 요구를 충족시키기에 명확한 한계를 가지고 있다. 따라서 연구를 통해 13.56MHz와 2.45GHz를 동시에 지원하는 Dual-Band RFID시스템을 개발하여 단일대역 RFID 서비스의 단점을 보완한다. 이를 위해 두 대역의 주파수를 지원하는 하드웨어와 소프트웨어를 개발하고, 능동형 태그의 배터리 수명에 관한 연구를 통해 보다 효율적으로 Dual-Band RFID 시스템을 구성한다.

In the recent years, the companies have manually recorded a production status in a work diary or have mainly used a bar code in order to collect each process's progress status, production performance and quality information in the production and logistics process in real time. But, it requires an additional work because the worker's record must be daily checked or the worker must read it with the bar code scanner. At this time, data's accuracy is decreased owing to the worker's intention or mistake, and it causes the problem of the system's reliability. Accordingly, in order to solve such problem, the companies have introduced RFID which comes into the spotlight in the latest automatic identification field. In order to introduce the RFID technology, the process flow must be analyzed, but the ASME sign used by most manufacturing companies has the difficult problem when the aggregation event occurs. Hence, in this study, the RFID logistic flow analysis Modeling Notation was proposed as the signature which can analyze the manufacturing logistic flow amicably, and the manufacturing logistic flow by industry type was analyzed by using the proposed RFID logistic flow analysis signature. Also, to monitor real-time information through EPCglobal network, EPCISEvent template by industry was proposed, and it was utilized as the benchmarking case of companies for RFID introduction. This study suggested to ensure the decision-making on real-time information through EPCglobal network. This study is intended to suggest the Modeling Notation suitable for RFID characteristics, and the study is intended to establish the business step and to present the vocabulary.

RFID 시스템은 최근 많은 주목을 받고 기술적인 발전이 이루어졌다. 기본적인 동작은 리더가 인식 거리 내에 있는 태그를 인식하는 동작이며， 수신된 태그의 데이터를 활용하여 다양한 분야에 응용이 가능하다. 그 중에 공연 무대 장치에 활용에 매우 적합한 시스템이라 할 수 있다. RFID 태그를 부착한 배우나 소품들이 특정 위치에 있는 리더의 인식 거리 내에 들어오면 태그를 인식하여 자동으로 무대 장치가 동작하도록 제어가 가능하기 때문이다. 하지만 무대라는 협소한 장소에 다수의 리더가 설치되어야 하므로 각 리더들의 인식 영역이나 다수 태그가 무대상에 있으므로 인식 상의 문제가 발생하게 된다. 본 논문에서는 이러한 문제를 해결하기 위한 관련 기술을 살펴보고 해결책을 제시하고자 한다. 또한 RFID 시스템을 효율적으로 공연 무대 장치에 활용하기 위해서는 향후 응용 모델을 제시한다.

In this paper, we investigate and present related technology or algorithm to solve these problem. We also present applicable model to apply efficiently for performance setting.

Ubiquitous application is in need of high-level technology to meet various requests for ubiquitous service. In order to adopt ubiquitous technology in not only pilot projects but also regional services, many projects like u-City are implemented in and outside the country. RFID has been known as one of the important technology to provide with core benefits of Ubiquitous services. Because each band of RFID technology has merits and demerits concurrently, single-band RFID system has limitations for various RFID services. Thus, we developed dual-band RFID system enable to provide with 13.56MHz and 2.45GHz RFID service at the same time to compensate the shortage of single-band RFID system. Also we have considered the way that the firmware would control signals without collision, studied battery life and range for tag, and made hardware for dual-band RFID service.
