Access and privacy control enforcement in RFID middleware systems: Proposal and implementation on the Fosstrak platform

International audienceRadio Frequency IDentification (RFID) technology offers a new way of automating the identification and storing of information in RFID tags. The emerging opportunities for the use of RFID technology in human centric applications like monitoring and indoor guidance systems indicate how important this topic is in term of privacy. Holding privacy issues from the early stages of RFID data collection helps to master the data view before translating it into business events and storing it in databases. An RFID middleware is the entity that sits between tag readers and database applications. It is in charge of collecting, filtering and aggregating the requested events from heterogeneous RFID environments. Thus, the system, at this point, is likely to suffer from parameter manipulation and eavesdropping, raising privacy concerns. In this paper, we propose an access and privacy controller module that adds a security level to the RFID middleware standardized by the EPCglobal consortium. We provide a privacy policy-driven model using some enhanced contextual concepts of the extended Role Based Access Control model, namely the purpose, the accuracy and the consent principles. We also use the provisional context to model security rules whose activation depends on the history of previously performed actions. To show the feasibility of our privacy enforcement model, we first provide a proof-of-concept prototype integrated into the middleware of the Fosstrak platform, then evaluate the performance of the integrated module in terms of execution time

A Secure Platform for Information Sharing in EPCglobal Network

With the rapid development of RFID technology, the EPCglobal network has drawn considerable attention from both research and industry communities, which enables supply chain partners to automatically share information and improve the visibility of supply chains. As the information shared in the EPCglobal network is usually sensitive and valuable, security mechanisms should be provided. In this paper, we aim at designing and implementing a secure information sharing platform in the EPCglobal network with a focus on authorization mechanism. We also design and implement a track and trace application based on the proposed secure platform so as to demonstrate its feasibility and practicality

Value chain dynamics in the RFID technology

Thesis (S.M.)--Massachusetts Institute of Technology, Sloan School of Management, 2006.Includes bibliographical references (leaf 66).RFID (Radio Frequency Identification) technology has been one of the oldest renewed technologies with a promise of becoming a foundation of "The Internet of Things" in future. MIT's Auto-ID labs and EPCGlobal have been instrumental in advocating standards, making mass scale adoption a reality. The early adopters were found to be in the retail supply chain industry followed by many interesting applications in areas ranging from Fish Tracking to authentication of currency notes. Projects implemented till 2006 were mainly pilot in nature with a desire to understand the technology, given its limitations and challenges and conclude with value propositions or return on investment analysis for corporations. This work has attempted to study such phenomenon in greater detail, bring together the dimensions of technology and business as related to the current state of RFID. We found a very different set of value dynamics applicable to each individual component in the RFID business landscape. Analysis on presented in more detail for manufacturers (Suppliers) of goods as well as Sellers (Retailers) of goods. Further work may be in the form of analyzing the remaining components like logistics players and end customers in a similar fashion.(cont.) Case studies and interview were done to collect data. Secondary sources of information in the forms of published reports and articles are also used and referenced. Management science techniques like Systems Dynamics are used to model some of the value parameters for each component in the retail supply chain. In conclusion, we think although each component of the studied landscape has shown value enhancement and erosion (primarily to cost factors), the overall system shows net gains. As all other technologies, RFID will become cheaper with increased adoption and has a very high probability to be prevalent and ubiquitous in near future.by Milind Tavshikar.S.M

Design And Implementation Of A Low-cost, Compact And Long Range Monostatic Uhf Rfid Reader With Read Point Extension

Tez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 2014Thesis (M.Sc.) -- İstanbul Technical University, Institute of Science and Technology, 2014RFiD sistemlerinin çeşitli uygulama alanlarında artan popülerliği neticesinde, özelikle UHF bandında çalışacak olan RFiD okuyucu üretimine dair ihtiyaçlar gittikçe artan bir eğilim göstermektedir. Bahsedilen ihtiyaçlar göz önüne alınarak, bu tez kapsamında yeni bir okuyucu tasarımı gerçekleştirilmiştir. Tasarlanan okuyucu, endüstriyel RFiD uygulamaları için gerekli görülen birçok ilgi çekici özelliği bünyesinde barındırmaktadır. RFiD sistemleri, kısaca radyo frekanslı kimliklendirme diye tanımlanabilmektedir. Elektromanyetik dalgaları kullanarak (kablosuz iletişim), üzerlerine RFiD etiketleri iliştirilmiş olan nesne, hayvan ve insanlardan verilerin transfer edilmesini sağlarlar. Takip, gözlem, kontrol vb. amaçlı kullanılabilmektedir. Genel itibari ile barkod sistemi gibi otomatik tanımlama teknolojileri ailesinin bir üyesidir. Tez kapsamındaki ilk iki bölümde, RFiD sisteminin detaylarına ve temel standartlarına dair bilgilere yer verilmiştir. Üçüncü bölümde, donanım sistem tasarımına ait süreçler detaylı bir şekilde ele alınmış ve simülasyon ile ölçüm sonuçlarına yer verilmiştir. Tasarlanan okuyucu; okuma noktası artırılmış, düşük maliyetli, kompakt, uzun menzilli ve Gen2 uyumlu olacak şekilde UHF bandında geliştirilmiştir. Aynı zamanda, birden fazla okuyucunun aynı anda çalıştığı yoğun ortamlarda çalışabilme özelliğine sahiptir. Okuyucu, anten çıkış gücü 30-dBm olan iki adet anten çıkış portu barındırmaktadır. Ayrıca, yenilikçi bir özellik olarak, geri yansıyan RF gücünü azaltmak için anten uydurma devresi tasarlanmıştır. Bu işlem, okuyucunun çıkış empedansının antenin empedansına uydurulması ile gerçekleştirilmektedir. Bununla birlikte, okuyucu, işlem anında antenin empedansını olası çevresel faktörlere karşı kararlı bir yapıda tutabilme kabiliyetine de sahiptir. Bunların yanı sıra, bir güç algılayıcı devresi vasıtasıyla, okuyucu için var olan yasal koşulları sağlamak adına, çıkış gücünü sınırlandırma ve kontrol etme özellikleri de mevcuttur. Donanım tasarımı esnasında, yüksek frekansta PCB tasarım teknikleri, radyo frekansı ve fizik temelleri, dijital ve analog devre tasarım teknikleri gibi farklı disiplinlerden çeşitli teknik bilgiler ve kabiliyetler kullanılmıştır. Artırılmış okuma noktası özelliği, tasarlanan bir başka donanım, RF çoklayıcı devresi, vasıtası ile sağlanmaktadır. Bu ürün sayesinde, UHF RFiD okuyucunun anten çıkışları artırılarak sistem kurulum maliyeti azaltılmaktadır. Bu cihazın amacı, çoklu anten ihtiyacı olan uygulamalarda okuyucu sayısını sabit tutarak, anten çıkış sayısını artırmaktır. Bu sayede sistemin uygulanma maliyetinde avantaj sağlanmaktadır. Ürün dahilindeki anahtarlama entegrelerinin araya girme kayıplarının az olması ve entegrelerin kontrolünü sağlayan denetleyici yapısı, okuyucuların marka modelinden bağımsız tak-çalıştır sistem modeli ürüne ait katma değerli nitelikleridir. Bu tez dahilinde tasarımı gerçekleştirilen UHF RFiD okuyucu, aynı zamanda Bilim, Sanayi ve Teknoloji Bakanlığı’nın sağlamış olduğu Ar-Ge proje destekleri kapsamında desteklenmiştir. Bu proje ve tez neticesinde, imalat masraflarını düşürmek adına okuyucu tasarımı ve üretimi yerli olarak gerçekleştirilmiş ve yurt içinde milli bir cihaz geliştirilmiştir. Proje sonucunda, başlangıçta belirlenen tüm kıstaslar başarıyla sağlanmış ve birer adet RF çoklayıcı devresi ve UHF RFiD okuyucu devresi, kontrol ünitesi ve grafiksel arayüz yazılımı ile birlikte, istenen herhangi bir RFiD uygulamasında kullanılmak üzere prototip olarak üretilmiştir.RFiD systems have an increasing popularity in various kinds of applications. Necessities are rising for the manufacture of new RFiD readers in industry especially at UHF band. Based on this concept, a new UHF RFiD reader design with extended read point capability has been presented within the scope of this thesis. Designed reader has attractive features required by some industrial RFiD applications. Before the hardware design part of the study, first, the background of RFiD and its key standards have been introduced in the first two chapters. In the third chapter, the hardware design process has been covered in detail and simulation and measurement results have been presented. The designed hardware is a low-cost, compact and long-range Gen2 compliant UHF RFiD reader with extended read point capability. The reader has up to 30 dBm (1 Watt) output RF power at two selectable antenna ports. The reader has an antenna tuning circuit, a novel feature, to reduce reflected RF power from antennas. This is achieved by tuning output impedance of the reader to the impedance of antenna. The reader can also tune the antenna impedance during operation in case the environment of the antenna changes. A power detector is used to control and limit the output power to regulatory requirements. While designing the hardware, several technical skills within a wide spectrum of disciplines were used like PCB design in high frequency, radio frequency, physics of RF, digital and analog design. Extended read point capability is provided with another hardware design called RF multiplexer circuit. This product has been designed in order to increase the number of antenna output ports of UHF RFiD reader to reduce the system implementation cost in dense antenna applications. This hardware design is also a part of another Research & Development project funded by the Ministry of Science, Industry and Technology of Turkey. As a part of this project and this thesis, the UHF RFiD reader has been designed as a domestic product to lower the cost of manufacture. As a result of this project, all the objectives have been achieved and a prototype of UHF RFiD reader, which has a control unit and a graphical user interface, and an RF multiplexer have been manufactured to be used in any desired UHF RFiD application.Yüksek LisansM.Sc

New Generation Sensor Web Enablement

Many sensor networks have been deployed to monitor Earth’s environment, and more will follow in the future. Environmental sensors have improved continuously by becoming smaller, cheaper, and more intelligent. Due to the large number of sensor manufacturers and differing accompanying protocols, integrating diverse sensors into observation systems is not straightforward. A coherent infrastructure is needed to treat sensors in an interoperable, platform-independent and uniform way. The concept of the Sensor Web reflects such a kind of infrastructure for sharing, finding, and accessing sensors and their data across different applications. It hides the heterogeneous sensor hardware and communication protocols from the applications built on top of it. The Sensor Web Enablement initiative of the Open Geospatial Consortium standardizes web service interfaces and data encodings which can be used as building blocks for a Sensor Web. This article illustrates and analyzes the recent developments of the new generation of the Sensor Web Enablement specification framework. Further, we relate the Sensor Web to other emerging concepts such as the Web of Things and point out challenges and resulting future work topics for research on Sensor Web Enablement
