Automatic Toll Tax Collection Using GSM

Every year researchers and engineers are finding new and useful applications for Radio Frequency Identification (RFID) systems (Finkenzeller, 2003). Because of the growing use of RFID systems, many different areas of research have also been developed to improve the performance of such systems. A few of these areas of research include novel antenna designs (Rao et at., 2005; Calabrese & Marrocco, 2008; Amin et al. 2009), analysis on the backscatter properties of RFID tags (Yen et al., 2007; Feng et al., 2006), mutual coupling between RFID tags (Li et al., 2008; Owen et al., 2009) and the deployment of RFID systems to complex and extreme environments (Qing & Chen, 2007; Sanford, 2008). There are many aspects to each area of research in RFID. A major topic in many of these areas involves research on the antenna design for RFID tags. This chapter will focus on the design of efficient space-filling antennas for passive UHF RFID tags. First, an introduction to RFID systems is presented. This is done by describing the major components in a RFID system and how they communicate. Then, the particular backscattering properties of a passive tag are described from a unique electric field integral equation standpoint and from an overall systems perspective (i.e., using the Friis transmission equation). This discussion will then be followed by a section describing a practical design process of various space-filling antennas for passive tags. Finally, a summary of future work and a conclusion about the chapter is presented.

Private companies and government have decided to provide Radio Frequency Identification (RFID) systems in places of free access to the population. However, as a result of such exposition, these systems become vulnerable to Denial of Service (DoS) attacks that can cause unavailability in the services. Furthermore, another complicating factor in that context regards the equipment or devices used on RFID systems, since they operate in frequency bands reserved for secondary communication systems, and consequently they have too few computational resources to deal with malicious electromagnetic interferences. Therefore, in this paper an Intrusion Detection System (IDS) is proposed to identify the occurrence of the malicious behavior and to notify the system operator about one specific type of electromagnetic interference in RFID systems - the Jamming attack. The obtained results of the system show the jamming attacks are detected prior of having a significant impact on the communication between the RFID reader and the tag - i.e., the jamming attack was detected even with insufficient power to impact on communication.

Remote technologies are changing our way of life. The radio frequency identification (RFID) system is a new technology which uses the open air to transmit information. This information transmission needs to be protected to provide user safety and privacy. Business will look for a system that has fraud resilience to prevent the misuse of information to take dishonest advantage. The business and the user need to be assured that the transmitted information has no content which is capable of undertaking malicious activities. Public awareness of RFID security will help users and organizations to understand the need for security protection. Publishing a security guideline from the regulating body and monitoring implementation of that guideline in RFID systems will ensure that businesses and users are protected. This chapter explains the importance of security in a RFID system and will outline the protective measures. It also points out the research direction of RFID systems.

Radio Frequency Identification (RFID) systems consist of Electric Tags, or transponders and RF tag readers, or transceivers. Auto-tags of the RFID system have the unique ID feature and are capable of carrying information, which adds the tags more capability of which could be read only or read/write. RFID systems are now being used by more and more organizations connected with management, tracing, and control. The purpose of this study was to develop a information protection system (named PC-guard) using systems engineering and RFID technology. The login verification code can be notified in advance by using the PC-guard system because every PC user having their own Auto-tag will be checked with PC RFID reader. The information in the PC will be protected with RFID and the vibration sensor as the PC be turned on and be invaded. The development of this system using Blanchard and Fabrycky's procedure intends to bring the advantages of time saving and reduced risk using RFID technology. The developmental test and evaluation in the RFID lab had been done. The test results show that the PC-guard system can be operated well to protect the information in the PC with an active RFID tag and a PLC procedure with vibration sensor.

In recent years, the research on Radio Frequency Identification (RFID) system has presented certain solutions that can meet the corresponding security requirements to some extents. However, the issues with multiple databases in RFID system, which are common in the real world, have gained little attention in the existing schemes. Although ONS (Object Name Service) solution is aimed at supporting multi-database in RFID system, it still has great security risk because of the lack of protection of the tag ID. In this paper, a new solution is presented which can provide sound protection of the tag ID and is adaptable to multiple databases, which can meet the security requirements of RFID system.

Two types of information, namely; related jobsite information along the process and feedback information have been found as essential elements for construction process improvement. In current practices, construction process has faced barriers in obtaining these two types of information. To overcome this problem, the new information system is proposed, namely; Radio Frequency Identification (RFID) system which consists of RFID as an automatic identification and data collection device integrated with database. Precast concrete installation process in housing projects has been selected to be a case study. The research had been initiated by reviewing related literatures and conducting field observations. The results of these initial studies are utilized as a basis in constructing the conceptual model of RFID application in precast installation process. The conceptual model is then realized by exploring the RFID characteristics and developing the prototype of RFID system afterwards. The exploration of RFID characteristics aims to reveal the basic characteristics of RFID that are essential to be recognized in supporting the proposed conceptual model. The general findings show that the tag orientations, tag positions, distance, interrogation angle, and the presence of other tags affect the RFID performance. The vertically oriented tag performs more superiorly than the horizontal one. The reading rate, the maximum amount of detected tags at once, and the minimum spacing distance between tags tend to decrease as the reading distance increases. The coverage area tends to be smaller when the reader rotates either horizontally of vertically. The design and development of RFID system is a prototype. It aims to enable the involved parties to collect the required data and to access the required information. The RFID system involves pre-input, input, and output modules. The pre-input and input modules collect associated data to the details of concrete panel information, and the information of precast installation process respectively. The output module presents the required information of the precast concrete panel and the information of the installation events. The information of the installation events is presented in forms of table and graphical views to provide simple analysis of the current precast installation practice. The RFID system provides related jobsite information and feedback information which can be used to improve the installation process of the precast concrete panels.

The characteristics of radio frequency identification (RFID) systems introduce growing security and privacy concerns. RFID systems need security protocols to provide confidentiality, user privacy, mutual authentication and etc. Many security protocols for the RFID system have been presented. This paper analyze several of the newest RFID security protocols which proposed by Niu et al., Fu et al. and Habibi et al. respectively form the security viewpoint of data desynchronization attack. These lightweight protocols were expected to proposed security protections for the RFID system and safeguard against almost all major attacks. However, we found that these RFID security protocols were vulnerable to the attack of data desynchronization. Based on strand spaces model, data desynchronization attacks on these protocols were analyzed and described. Furthermore, improvements to overcome the security vulnerabilities of two protocols presented by Niu et al. and Fu et al. were given. DOI: http://dx.doi.org/10.11591/telkomnika.v11i2.1993

Sensor networks as well as radio frequency identification (RFID) systems are among the hyped technologies nowadays. A lot of research efforts have been spent to develop standards, middleware and applications. The industry has already made large investments to foster the adoption of these technologies, consequently pushing the development, and already deploying the resulting technologies in different domains. However, the addressed technologies are still very young; best practices as well as standards are expected to frequently change, as new demands arise when using the technologies in everyday life. Because of this, middleware systems are expected to undergo frequent redesigns as well, requiring well-suited design paradigms to avoid a software engineering nightmare. We therefore propose an agent-based middleware for sensor networks and RFID systems. This middleware will meet the challenges for having a robust, adaptable and flexible middleware, which is, moreover, easily extensible to cope with expected re-engineerings and changes while maintaining a clear and elaborate design.

The first topic in this chapter was an introduction to RFID systems. This was followed immediately with a discussion on metamaterials and LH-propagation. Expressions for the propagation constants, phase velocity and Bloch impedance were derived and discussed. Next, several metamaterial-based antenna designs for passive RFID tags were presented. The designs offered showed that by incorporating elements found in metamaterials in the design of the antenna on a RFID tag, the antenna could be made to resonate at a much smaller dimension. The result is a compact passive RFID tag with very useful max read range values.

In recent years, numerous authentication protocols for radio frequency identification (RFID) systems have been proposed to protect privacy. Due to the hardware resource limitation on RFID tags, the majority of these protocols are based on symmetric-key ciphers. However, most of them lack scalability at the reader side as they require a linear or logarithmic search proportional to the number of tags in the system in order to authenticate a tag. Recently proposed scalable protocols require a constant-time search and utilize hash look-up tables. However, the storage requirement of the hash-table in these protocols is very large, therefore not practical. Moreover, previous proposals do not support dynamic resizing where the number of tags changes during the life time of the RFID system. In this paper, a new Re-Hash technique is presented to reduce the hash-table storage in constant-time authentication protocols. To the best of our knowledge, it offers the smallest storage cost in comparison to previous proposals. The Re-Hash technique is also further adapted to support the dynamic scalability for RFID systems.

In this chapter, we discuss the business implications, as well as security and privacy issues, of the widespread deployment of radio frequency identification (RFID) systems. We first describe, in more detail, the components that make up an RFID system to facilitate better understanding of the implications of each, and then review the commercial applications of the RFID. We then discuss the security and privacy issues for RFID systems and what mechanisms have been proposed to safeguard these. The topics discussed in this chapter highlight the benefits of using RFIDs for user convenience in ubiquitous and pervasive commercial services and e-businesses, while maintaining the integrity of such systems against malicious attacks on the users’ security and privacy. This is vital for a business establishment to coexist with peers and remain competitively attractive to customers.

This paper discusses the separation of signals in multiple-tag radio frequency identification (RFID) systems. First, a model for the RFID system in both single and multiple tag environments is presented. Then, an analytical constant modulus algorithm (ACMA) for the blind source separation problem is reviewed. An alternative approach to the traditional ACMA using joint diagonalization is considered. Finally, both the ACMAs are applied to the multiple-tag RFID environment and performance of the system is studied. Simulations are carried out for 4-QAM and 16-QAM modulations at tag and analyses of the simulation results reveal that the ACMA with joint diagonalization takes lesser CPU time to execute compared to the traditional ACMA, but with higher average modulus error (AME). The variation of system performance with the number of measurements, SNR (signal to noise ratio), number of tags and number of antennas at the reader is also studied. Based on these, some design guidelines are presented. Interestingly both the ACMA algorithms work for the 16-QAM case and yield trends similar to those of 8-PSK and 4-QAM.

In this paper, we focus on configuring a low cost RFID (Radio Frequency IDentification) system with less RFID readers and low density RFID tag textiles for stable and accurate self-localization for an omni-directional mobile robot. An RFID system using multiple RFID readers and high density RFID tags has already been applied to an indoor mobile robot self-localization. However, the system production cost is relatively high. To reduce the production cost of the system while maintaining the self-localization performance, we redesign two new RFID systems configured with 20 RFID readers and 5 RFID readers enlarging the size of an RFID reader antenna. Particularly, a new likelihood function of the tag detection with the redesigned large size RFID reader antenna is proposed for Monte Carlo Localization (MCL). Furthermore, we come up with a novel arrangement of RFID tags installed in a hexagon pattern. The new arrangement of ID tags enables both low cost ID tag installation and high performance of self-localization. We examine the performances of robot self-localization with less RFID readers and lower density RFID tags installed on the floor based on MCL(Monte Carlo localization). The simulation demonstrates the validity of our proposed configuration of the RFID based self-localization.

There are many protocols proposed for protecting Radio Frequency Identification (RFID) system privacy and security. A number of these protocols are designed for protecting long-term security of RFID system using symmetric key or public key cryptosystem. Others are designed for protecting user anonymity and privacy. In practice, the use of RFID technology often has a short lifespan, such as commodity check out, supply chain management and so on. Furthermore, we know that designing a long-term security architecture to protect the security and privacy of RFID tags information requires a thorough consideration from many different aspects. However, any security enhancement on RFID technology will jack up its cost which may be detrimental to its widespread deployment. Due to the severe constraints of RFID tag resources (e.g., power source, computing power, communication bandwidth) and open air communication nature of RFID usage, it is a great challenge to secure a typical RFID system. For example, computational heavy public key and symmetric key cryptography algorithms (e.g., RSA and AES) may not be suitable or over-killed to protect RFID security or privacy. These factors motivate us to research an efficient and cost effective solution for RFID security and privacy protection. In this paper, we propose a new effective generic binary tree based key agreement protocol (called BKAP) and its variations, and show how it can be applied to secure the low cost and resource constraint RFID system. This BKAP is not a general purpose key agreement protocol rather it is a special purpose protocol to protect privacy, un-traceability and anonymity in a single RFID closed system domain.

최근 RFID (Radio Frequency Identification) 기술이 다양한 분야에서 관심을 받고 사용됨으로써 RFID 리더 제조회사들은 다양한 종류의 리더를 생산하고 있다. 현재 RFID 기술에서 RFID 태그 데이터 전송 형태는 EPCglobal에서 제공하는 표준 규약을 따르고 있지만 각 리더 별 리더 연결 및 통신 방법은 회사별로 다른 실정이다. RFID 리더를 사용하던 중 타 회사나 리더 인터페이스가 다른 RFID 리더로 변경하거나 새롭게 추가해야 하는 경우에는 사용자가 직접 RFID 미들웨어 개발단계로 돌아가 미들웨어의 내부 요소를 변경해야 하는 상황이 발생한다. 본 논문에서는 RFID 기술을 사용 시, 특히 여러 회사 또는 표준화되지 않은 인터페이스를 제공하는 RFID 리더를 사용하는 경우에 RFID 애플리케이션과 독립적으로 리더를 관리할 수 있는 리더 프레임워크를 개발하고자 한다. 본 리더 프레임워크는 RFID 애플리케이션과 RFID 리더 사이에 존재하여 RFID 리더 투명성을 제공한다. 본 리더 프레임워크는 현재 작동되고 있는 리더를 모니터링 할 수 있고, 리더의 속성을 확인할 수 있으며 RFID 태그 이벤트 정보, 시스템 로그 정보를 확인할 수 있다. 본 리더 프레임워크를 통해 수십 대의 이기종의 RFID 리더 상태를 용이하게 관리할 수 있게되며 애플리케이션 상의 코드 수정 없이 리더의 추가, 삭제가 가능하게 된다. More recently, variety RFID (Radio Frequency Identification) readers are produced by RFID equipment manufactures. Although a transmission standard instituted by EPCglobal is proposed for data transmission between the RFID readers and tags, other RFID reader protocols and the communication connection methods are be in use in other RFID companies. To replace or add the RFID readers of an RFID system, the developers should make changes to the core of the application and/or middleware. In this paper, we propose an RFID reader framework which can manage RFID readers without having to make changes the code of the application in environment with the growing number of heterogeneous RFID readers.This framework that sits on the layer between the RFID readers and the applications provides transparency to the RFID readers. Additionally, it can be used for monitoring the state and the property of all connected RFID, and for recording the RFID tag event logs and system logs. By using this framework, heterogeneous readers can be replaced and added without writing additional code in the applications. Consequently the readers can be easily managed and controlled by the RFID system administrator.
