The widely adopted EPC Network fails to adequately support application services for event stream capture and lacks event communication methods to provide indirect exchange of events in distributed activities of complex event detection. This work presents an RFID software framework whose purpose is to raise the inter-organizational integration of an RFID middleware through cooperative complex event processing (CEP) mechanisms based on event notification services. Experimental results show that the framework improves activities of design and development of RFID applications and adds new features for integrating, managing and sharing RFID event data.","PeriodicalId":222446,"journal":{"name":"2011 IEEE International Conference on RFID","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129341054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inkjet printing has been chosen to provide a substrate, which suits the aim of concealment for the final device. Moreover, this paper shows how the inkjet printing techniques perfectly match the text-based design proposed in terms of high applicability.

In many practical business processes using RFID, we check not only individual objects but also check if there is no missing objects and no extra objects in a group of objects. While individual objects identifications are done by using RFID, group verifications are usually done by looking up a shipping list or corresponding EDI data which require a network connection. In this paper, we propose “group coding of RF tags” by which we can verify the integrity of a group of objects just by writing additional data in RF tags' memory. The additional data is computed from unique IDs of objects that belong to the group. We propose fundamental and general group codings. With the fundamental group coding, we can check if the integrity of a group of objects is preserved or not. It is a parity check of hashes of unique IDs in a group. We also propose general group coding by extending the fundamental group coding. With the general group coding, we can estimate the number of missing objects if the integrity of a group is not verified. The strength of the missing number estimation can be controlled by the size of data written to RF tags. It can be considered as a Low Density Parity Check (LDPC) in physical objects. The theory of group coding is confirmed by a numerical simulation and an experiment. It is shown by the simulation and experiment that we can detect 10 missing RF tags out of 20 RF tags with 99.5% reliability by writing 96-bit data into each RF tags besides its 96-bit unique ID.","PeriodicalId":222446,"journal":{"name":"2011 IEEE International Conference on RFID","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130436699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analyses are based on ultra-wideband (UWB) channel measurements performed in a warehouse portal, which is a severe multipath environment. It is illustrated that the available bandwidth of the usual ISM bands at 900 MHz, 2.5 GHz and 5.8 GHz is only sufficient for a precise RFID tag localization if moderate or low multipath conditions are given. However, in severe multipath channels the ISM bands are unsuited and UWB signals are needed. The results can be considered a lower bound for signal time of flight (TOF) based localization approaches that utilize Fourier or correlation methods for the signal travel time estimation.","PeriodicalId":222446,"journal":{"name":"2011 IEEE International Conference on RFID","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134490907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present RFID-CoA; a system that aims to render typical RFID tags physically unique and hard to near-exactly replicate by complementing them with random 3D scattering structures, which serve as certificates of authenticity (CoA). The unique near-field response, or “fingerprint”, of the CoAs is extracted as a set of S21 curves by our reader prototype, the design and development details of which are discussed. The results of our performance analysis show that the intersection probability of the false positive and false negative error probability curves is inconceivably small (<10−200). The RFID-CoA tag's lifecycle from fabrication site to store is presented, and a strategy to block potential attacks is discussed. Our system bridges the world of RFID with a large array of anti-counterfeiting applications by exploiting “hardware-enabled”, modified-material scattering characteristics in the near-field.

The importance of such ciphers are further highlighted by novel manufacturing technologies, such as printed ink to develop extremely low cost RFID tags. Such developments bring new challenges, especially in terms of providing security, both to protect privacy as well as to enable applications dependent on security, such as e-tickets. In this paper we present a new stream cipher, A2U2, which uses principles of stream cipher design and approaches from block cipher design. Our lightweight cryptographic primitive has taken into consideration the extremely resource limited environment of printed ink tags, to develop a cipher that can be implemented with less than 300 gates, with the added benefit of high throughput provided by stream ciphers.","PeriodicalId":222446,"journal":{"name":"2011 IEEE International Conference on RFID","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114216204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reynolds","doi":"10.1109/RFID.2011.5764606","DOIUrl":"https://doi.org/10.1109/RFID.2011.5764606","url":null,"abstract":"In many safety-critical applications, battery performance is a significant limiting factor that affects the feasibility of electronic safety devices intended to alert workers to hazardous situations. In particular, battery capacity and lifetime are difficult to predict when safety devices are exposed to extremes of temperature, humidity, shock, and vibration that are common in construction, excavation, drill rigs, and mining work sites. Because battery failure is unacceptable in safety devices, periodic preventative maintenance is required, adding to device cost and labor cost and reducing acceptance of electronic safety devices. Energy harvesting and communications techniques based on passive UHF RFID technology may offer an alternative to battery power for some types of safety alert devices, particularly where hazardous conditions are created by powered heavy equipment. We present a worker safety device designed around a passive UHF RFID platform that derives its operating power from specialized interrogators mounted on heavy equipment. This device is designed to be integrated with plastic hard hats that are commonly used in the construction industry to yield an intelligent hard hat, called a “SmartHat”, that delivers an audible alert directly to workers in proximity to a particular piece of equipment. It is addressible using an ASK interrogator-to-tag link, and backscatters confirmation that an alert has been delivered to the worker. We present the design of the SmartHat tag, including a compact printed-circuit vee style antenna, an RF-to-DC power harvesting circuit, and a microprocessor-driven alert speaker. The tag's average operating power while delivering a pulsed alert is 1.8V at 61μA, or 110μW (−9.6 dBm). Its power-up threshold when not delivering an alert is 1.8 V at ≈ 10μA. We also present a specialized interrogator device operating under FCC Part 18 rules in the 902–928 MHz band that is mounted to a piece of construction equipment to power and communicate with nearby SmartHats. In outdoor testing of the SmartHat tag and its companion interrogator device, +35 dBm transmitter output power feeding a 9dBi Yagi antenna (+44 dBm EIRP) allows for safety alerts to be delivered at distances of up to 16.46 m.","PeriodicalId":222446,"journal":{"name":"2011 IEEE International Conference on RFID","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127720899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
