关键词： Cyber laws   Radio-frequency identification attacks   United Arab Emirates  

摘要： With the widespread use of radio-frequency identification (RFID) technology as a means for commerce and identification, new types of cybercrime have emerged. Accordingly, revisions to extant cybercrime law are required. This research attempts to determine the relevance of current UAE laws in addressing new cybercrimes on emergent technologies. We reviewed the literature to identify threats to RFID systems, classifying works into three categories: blocking, interception, and physical attacks. We mapped these categories to 50 articles of the UAE cybercrime law to assess their relevance. According to the distribution of law articles pertaining to RFID attacks, it was found that RFID communication interception attacks are not sufficiently addressed in the law and that further amendments are required in the UAE. Example of international statutes are highlighted as models.

关键词： Chipless RFID   encoding capacity   notch filter   reconfigurable RFID   tag antenna  

摘要： A novel reconfigurable chipless RFID tag to enhance encoding capacity is proposed in this paper. The entire transmission network includes four non- interacting ports that are independent separately. The reconfigurability can be realized by combining different ports to get different encoding results. To increase the anti-interference capability of the tag, a method of cross-combination for unit coders is proposed according to the spacing distances of the unit coders. The encoding ability of about 8-bit information can be obtained by using the compact tag structure with a dimension of 70 x 70 mm2 and the encoding capacity can be increased by increasing the number of unit coders. Code "1" or "0" is defined by arranging the appearance or disappearance of a unit coder. Typical encoding examples are presented and the simulation results match well with the measurement results, demonstrating the effectiveness of the proposed tag. The proposed tag can be used for structural health monitoring with the advantages of battery-free, large information capacity, and flexible usage.

摘要： To remain competitive, SMEs and small farming businesses in particular would need to effectively respond to technological trends and leverage their potential through better ICT strategies. However, the extant literature seldom examines why small farming businesses initiate ICT and how ICT can transform their business processes, let alone in a cross-national context. As such, the purpose of this interpretive case study, conducted in the UAE and Taiwan, aims to develop a multi-theoretical understanding of small farming organizations' strategic responses toward RFID. Based on three contrasting theoretical lenses, our analysis shows that institutional forces and governmental involvement in particular strongly influence small farming organizations' strategic decisions. While cost efficiency is also a significant consideration, no apparent evidence can be reflected upon resource- based view. We also find that cross-national differences of technology initiative exist between the UAE and Taiwan. Insights gained suggest that SMEs' technology initiative need to primarily focus on better exploiting institutional forces that may facilitate their strategic responses toward emerging technologies.

关键词： artificial magnetic conductor (AMC)   long-read range   metamaterial   passive RFID tag   radio-frequency identification (RFID)   tag antenna  

摘要： A new, high-gain, high-efficiency, long-range passive metamaterial UHF-RFID tag is proposed. Measuring 16.1 x 8.1 x 1.6 cm, it integrates a modified taper-shaped dipole antenna with the NXP UCODE 8 chip and an artificial magnetic conductor (AMC) structure shaped like a double open-end wrench. This cost-effective tag achieves read ranges comparable to those of battery-assisted passive (BAP) tags, up to 64.7 m in a shipping container at 918 MHz and 56.7 m in free space at 928 MHz. Theoretical analysis shows moderate agreement with experimental validation in an anechoic chamber and outdoors. The proposed tag addresses challenging scenarios, enabling previously unattainable passive RFID applications. It supports vessel detection in maritime environments, with potential uses in automated access control at bridges, gates, and locks in smart waterways and premier marinas. It also supports multivehicle detection, allowing applications, such as streamlining emergency services and smart city traffic management. Furthermore, its capability extends to smart hangar applications, such as automatic updates to pilots' electronic logbooks and aircraft supervision.

摘要： Over the past century, passive Radio Frequency Identification (RFID) has brought a revolutionary shift in inventory checking and object identification. In inventory management systems, RFID technology has been widely adopted by industries to streamline inventory tracking processes. However, the use of metallic racks to store inventory presents challenges to the accuracy of RFID-based systems. This research paper explores the adverse impact of the nearby metal environment with its effects on the efficacy of RFID at high frequency (HF). This study focuses on examining the impact of metal interference within a replicated metallic rack space and explores different metal environment scenarios to enhance the detection performance of RFID-tagged inventory items. The study examines two read detection patterns generated by radio frequency (RF) waves, one without the influence of metal environment, and another under the influence of different metal environments, including all six cubical sides of the RFID transponder read region. The findings reveal that each metal environment exhibits unique interference characteristics, although there are some similarities in reading patterns observed. Additionally, the study provides a comparison of the observed differences and explores the potential explanations of each distinct interference. Finally, the study suggests methods to improve the read detection rate in specific regions of the metal environment and explore the potential future work of this study.

摘要： Objectives: RFID tags on surgical instruments allow tracking of individual instruments. However, the tags on the instruments can restrict the handling, potentially increasing patient risks. Previous studies analyzed hand contact areas to identify potential locations for tags. However, the studies did not conduct interaction tests using instruments equipped with RFID tags, potentially neglecting the influence of haptic perception. In addition, previous studies required time-consuming evaluations by clinicians. Methods: Therefore, the present study aims to verify the previous findings in interaction-centered tests with clinicians using real RFID tags on the instruments. Additionally, we had instrument design experts rate RFID tag positions and examined whether they could predict the clinician's preferred tag positions. Results: We found that nearly all RFID tag positions decreased the user satisfaction of clinicians compared to a reference instrument. Compared to previous studies, our study shows that the RFID tag influences the orientations in which an instrument can be comfortably held, which was criticized by clinicians. Instrument design experts could only predict the clinician's preferred tag positions for some instruments. Conclusions: Therefore, we recommend investigating further changes to instrument design, for what the "ideal" positions proposed by the clinicians in this study can provide initial pointers.

关键词： RFID technology   Electric power materials   Full supply chain   Multi-dimensional early warning   Time window  

摘要： Early warning system needs to process a large amount of real-time data, and carry out in-depth analysis and mining of these data to identify potential risks and hidden dangers. However, existing data processing and analysis capabilities may not be able to meet this demand. To this end, a multi-dimensional early warning of the entire supply chain of power materials based on radio frequency identification (RFID) technology is designed. According to the real-time failure probability of power materials, the probability of early warning accidents is calculated and classified, and the risk is graded based on these probabilities. Through the methods of bonus points, deduction points, and grade evaluation, the risk early warning indicators of different stages in the whole supply chain of power materials were quantified. The objective and rationality of risk assessment can be ensured by means of comprehensive weight. A multi-dimensional early warning system based on RFID technology is established, combining multiple linear regression models and particle swarm optimization algorithms to determine the time window of multi-dimensional early warning, and carry out dynamic monitoring and early warning of the supply chain. The experimental results show that the early warning effect of the design method can reach 95% and the highest early warning effect can reach 98% at 10 s. The average warning error is only 2.91%, and the average warning time is only 1.34 s, which is more accurate in identifying the number of first-level risks, second-level risks, and third-level risks.

摘要： Medication nonadherence significantly reduces the effectiveness of therapies, yet it remains prevalent among patients. Nonadherence has been linked to adverse outcomes, including increased risks of mortality and hospitalization. Although various methods exist to help patients track medication schedules, such as the Intelligent Drug Administration System (IDAS) and Smart Blister, these tools often face challenges that hinder their commercial viability. Building on the principles of dosage measurement and information communication in IoT, we introduce the Smart Pill Case—a smart health adherence tool that leverages RFID-based data recording and NFC-based data extraction. This system incorporates a load cell for precise dosage measurement and features an Android app to monitor medication intake, offer suggestions, and issue warnings. To enhance the effectiveness and personalization of the Smart Pill Case, we propose integrating federated learning into the system. Federated learning allows the Smart Pill Case to learn from medication adherence patterns across multiple users without compromising individual privacy. By training machine learning models on decentralized data collected from various Smart Pill Cases, the system can continuously improve its recommendations and warnings, adapting to the diverse needs and behaviors of users. This approach not only enhances the tool’s ability to support medication adherence but also ensures that sensitive user data remains secure and private. © 2024, CC BY.
