Study on an Information System Integration Scheme of Enterprises Based on RFID Technology with SOA

Radio frequency identification(RFID) is high technology, which can rapidly and real-timely acquisition information and accurately deal with information. And it has broad application prospects in retail, logistics, transport and other fields. Service oriented architecture(SOA) is a service-oriented architecture, which is used to design and realize the loose coupling software. For the existing shortcomings of current enterprise information system integration, the RFID technology and SOA are introduced into system integration in order to propose a new enterprise information system integration scheme in this paper. In the proposed system integration scheme, the middleware uses the business documents as the carrier of data exchange among other enterprise application systems, and the data stream technology is used to filter and package RFID data. The rule parsing technology is used to control the business processes. The SOA is used to realize the loose coupling and integration of RFID data event and application system, and deal with the configuration of the components. At the same time, .NET Remoting technology is used to realize the distribution architecture of middleware in order to ensure the deployment flexibility of middleware. The applied cases of a demonstrative application system, blood management and traceability system are used to illustrate its feasibility and effectiveness of the proposed integration scheme. The enterprise information system integration scheme provides an effective solution for system integration between different enterprises or internal enterprises. It can solve the compatibility between different application systems, and takes on the higher service efficiency, less CPU average occupation and better average response time. This study provides a stable and effective solution for information sharing between enterprises, improves the work efficiency and reduces the whole work management capital, and continuously improves the informatization level of the enterprises.

Processing Uncertain RFID Data in Traceability Supply Chains

Radio Frequency Identification (RFID) is widely used to track and trace objects in traceability supply chains. However, massive uncertain data produced by RFID readers are not effective and efficient to be used in RFID application systems. Following the analysis of key features of RFID objects, this paper proposes a new framework for effectively and efficiently processing uncertain RFID data, and supporting a variety of queries for tracking and tracing RFID objects. We adjust different smoothing windows according to different rates of uncertain data, employ different strategies to process uncertain readings, and distinguish ghost, missing, and incomplete data according to their apparent positions. We propose a comprehensive data model which is suitable for different application scenarios. In addition, a path coding scheme is proposed to significantly compress massive data by aggregating the path sequence, the position, and the time intervals. The scheme is suitable for cyclic or long paths. Moreover, we further propose a processing algorithm for group and independent objects. Experimental evaluations show that our approach is effective and efficient in terms of the compression and traceability queries.

Security Threats and Challenges for RFID and WSN Integration

Radio Frequency Identification (RFID) and Wireless Sensor Network (WSN) are the combined technologies that will spread in the near future to enter all of our everyday activities. However, the security of these technologies is very much vulnerable. Adding some security measures to small computation powered devices that cannot handle the available security algorithms is considered a challenge. However, even low powered devices must be protected in ways that will present sufficient computational challenges to adversaries. This paper introduces suggested steps to build a secure protocol for the combined RFID and WSN technology application systems. Moreover, it demonstrates the possible attacks and threats on these combined technologies by analyzing their system environment and finally it discusses the possible threats that may occur.

A Novel Method for Modeling RFID Data

The applications of Radio Frequency Identification (RFID) and Electronic Product Code (EPC) in supply chain management have vast potential in improving effectiveness and efficiencies in solving supply chain problems. RFID data, however, have their own unique characteristics – including aggregation, location, temporal and history-oriented – which have to be fully considered and integrated into the RFID data model which is constructed for RFID application system. In this paper, we use an expressive temporal data model for RFID data. This data model is based on Entity-Relation (ER) model with minimum extension and highlights the state history and temporal semantics of the RFID system business processes. We also show common RFID data tracking and monitoring types, and propose methods to express such queries based on this data model.

RFID application in manufacturing: A case study on a pilot RFID project in household appliance production

Radio Frequency IDentification (RFID) is becoming an increasingly popular new technology in manufacturing. However, there are a lot of problems to be solved, such as architecture, process reengineering, and cost control. A case of RFID application in household appliance production lines is studied in this article. A three-layered architecture is presented for integrating the RFID system with the original manufacturing execution system and enterprise resource planning system, and the detailed workflow of the RFID application is introduced. In this case, the barcode technology is retained in some operations to bridge the legacy systems and the new RFID application system economically. Finally, the practical effects of the RFID application in a refrigerator production line have shown that the presented RFID application system is helpful to improve the production efficiency and reduce the cost of business operations for the enterprise.

New mutual agreement protocol to secure mobile RFID-enabled devices

The design of a secure communication scheme for Radio Frequency IDentification (RFID) systems has been extensively studied in recent years in view of the awareness of individual privacy and the requirement of robust system security. Most of previous works assume the communication channel between an RFID reader and its backend server is secure and concentrate on the security enhancement between an RFID tag and an RFID reader. However, once RFID reader modules are extensively deployed in consumers' handheld devices, the privacy violation problems at reader side will be deeply concerned by individuals and organizations. In this paper, we assume the future communication environment for RFID systems will be all wireless and insecure. Under such infrastructure, handheld device, such as mobile phone, embedded with RFID reader modules will be situated everywhere and operated with many RFID tags in various RFID application systems. In the meantime, it is more difficult to secure the privacy of a mobile RFID-enabled device than before without novel communication protocol. Hence, we propose a new mutual agreement protocol to secure the authenticity and privacy of engaged mobile RFID readers while constructing a secure session key between a server and a reader. Based on our security analyses, we show that our scheme can enhance data security and provide privacy protection at reader side even in the presence of an active adversary under insecure mobile RFID environment.
