An integrated framework for the development of radio frequency identification technology in the logistics and supply chain management

Radio Frequency Identification (RFID) features high storage capacity, remote access, excellent data security, and multiple-tag reading. Hence, RFID technology attracts attention from various industries, especially the logistics and retail industries. Due to the swift development of technology and the trend of globalization, the logistics managers are assigned the task to integrate the supply chain via information technology such as RFID. The goal is to achieve information sharing and reduction of total cost, thus the operation efficiency can be improved and competitive advantage can be enhanced. Thus, this research would first identify the key factors of RFID technology development in the logistics and supply chain management. A complete set of five dimensions and 24 factors with a hierarchy structure is presented. The Fuzzy Delphi and Fuzzy Analytic Hierarchy Process methods are adopted for analysis. A structural procedure of RFID system establishment is also constructed based on the key dimensions and factors, with the expectation of establishing the RFID system in an effective and efficient manner. Then, based on the experience of Taiwanese government and industry, the sequence of companies for adopting the RFID technology is discussed. Thus, an integrated framework for the development of RFID technology, which includes the hierarchy of factors, structural procedure, and sequence of adoption, is presented in this research; and it can be applied in other scenarios after the users make some modifications according to their specific needs.

ID-Services: an RFID middleware architecture for mobile applications

The use of RFID middleware to support application development for and integration of RFID hardware into information systems has become quite common in RFID applications where reader devices remain stationary, which currently represents the largest part of all RFID applications in use. Another field for applying RFID technology which is offering a huge set of novel possibilities and applications are mobile applications, where readers are no longer fixed. In order to address the specific issues of mobile RFID-enabled applications and to support developers in rapid application development, we present ID-Services, an architecture for an RFID middleware that is designed to support mobile applications. The ID-Services approach has been used to implement MoVIS (Mobile Visitor Information System), a mobile application which allows museum visitors to request individually adapted multimedia information about exhibits in an intuitive way.

Efficient detection of counterfeit products in large-scale RFID systems using batch authentication protocols

RFID technology facilitates processing of product information, making it a promising technology for anti-counterfeiting. However, in large-scale RFID applications, such as supply chain, retail industry, pharmaceutical industry, total tag estimation and tag authentication are two major research issues. Though there are per-tag authentication protocols and probabilistic approaches for total tag estimation in RFID systems, the RFID authentication protocols are mainly per-tag-based where the reader authenticates one tag at each time. For a batch of tags, current RFID systems have to identify them and then authenticate each tag sequentially, one at a time. This increases the protocol execution time due to the large volume of authentication data. In this paper, we propose to detect counterfeit tags in large-scale system using efficient batch authentication protocol. We propose FSA-based protocol, FTest, to meet the requirements of prompt and reliable batch authentication in large-scale RFID applications. FTest can determine the validity of a batch of tags with minimal execution time which is a major goal of large-scale RFID systems. FTest can reduce protocol execution time by ensuring that the percentage of potential counterfeit products is under the user-defined threshold. The experimental result demonstrates that FTest performs significantly better than the existing counterfeit detection approaches, for example, existing authentication techniques.
