Serialized TID numbers do not provide any cryptographic protection, but they do introduce a practical hurdle against adversaries who want to clone RFID tags today. Furthermore, serialized TID numbers are important for end-users who want to protect their current UHF tags from cloning since cryptographic tags are not yet commercially available in that frequency range. In this overview paper, we analyze the suitability of serialized TID numbers for security applications by evaluating the effort to bypass the TID check based on known vulnerabilities and we compare this effort to the needed level of protection in an example of anti-counterfeiting in the tobacco industry. The analysis illustrates that the practical hurdle of TID checks is not high enough for industrial-scale security applications and that it can completely diminish due to commodification of the RFID technology. However, end-users of security applications can still benefit from the increased tag cloning resistance that serialized TID numbers provide before migrating to more secure solutions.","PeriodicalId":417077,"journal":{"name":"2009 IEEE International Conference on RFID","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130602220","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 battery's capacity and the application's power demand influence the operational lifetime of the tag. Therefore, the designated application and lifetime requirement have to be kept in mind when designing a higher class tag. Moreover, the lifetime requirement needs to be verified in order to ensure the application will be successful. However, verification of the lifetime requirement is usually a very complex task. A verification environment for the application and its lifetime requirement needs to be created manually. After simulation with a battery model the results can be compared to the requirements document. Due to the complex and time-consuming nature of verification this often results in later time-to-market and increasing costs. In this work we present a novel, highly automated methodology to verify battery lifetime requirements. From the requirements document of the higher class UHF RFID tag a verification environment is created automatically. After power estimation is performed a battery model can be connected to the automatically generated lifetime verification environment. Finally, simulation is performed to verify whether the higher class UHF RFID tag fulfills the lifetime requirement of the application. The main benefit of our methodology is a decrease in the verification effort due to the high degree of automation in the creation of the verification environment. Moreover, simulation time is decreased which enables faster exploration of various batteries. This results in faster time-to-market and a reduction of costs.","PeriodicalId":417077,"journal":{"name":"2009 IEEE International Conference on RFID","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129339161","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}

RFID has become one of the primarily means to construct a real-time locating system (RTLS) that tracks and identifies the location of objects in real time using simple, inexpensive tags attached to or embedded in objects and readers that receive the wireless signals from these tags to determine their locations. Most RFID tag localization techniques heavily rely on precise estimation of the range between a reader and the tags. Traditionally, range information is obtained from the received signal strength indication (RSSI). Such approach is inaccurate, particularly in a complicated propagation environment. Recent development on phase difference of arrival (PDOA) allows coherent signal processing for improved range estimation performance. Exploiting multiple frequencies may further improve the range estimation performance. In this paper, we focus on multifrequency-based techniques to achieve several important advantages in the range estimation of passive or semi-passive RFID tags. The use of well designed multiple frequencies allows effective phase upwrapping and elimination of the range ambiguity problem which may be encountered in PDOA methods. In a complicated propagation environment, the mutifrequency-based techniques provide frequency diversity for robust range estimation when signals are highly faded at some frequencies. These advantages not only yield improved range estimation accuracy of RFID tags in various applications, but also enable robust range estimation in challenging scenarios.","PeriodicalId":417077,"journal":{"name":"2009 IEEE International Conference on RFID","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133600208","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}

Yet, the uniquely identifiable objects pose a privacy threat to individuals carrying the objects. Most previous work on privacy-preserving RFID technology, such as EPC re-encryption and killing tags, focused on the threats caused by the physical RFID tags in the data collection phase, but these techniques cannot address the privacy threats in the data publishing phase, when a large volume of RFID data is released to a third party. In this paper, we study the privacy threats caused by publishing RFID data. Even if the explicit identifying information, such as name and social security number, has been removed from the published RFID data, an adversary may identify a target victim's record or infer her sensitive value by matching a priori known visited locations and timestamps. RFID data by default is high-dimensional, so applying traditional anonymity model to RFID data suffers from the curse of high dimensionality, and would result in poor data usefulness. We define a new privacy model, develop an anonymization algorithm to address the special challenges on RFID data, and evaluate its performance in terms of data quality and efficiency.","PeriodicalId":417077,"journal":{"name":"2009 IEEE International Conference on RFID","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131384396","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}

SAW has many unique advantages over possible competing technologies, including the following characteristics: passive, radiation hard, operable over wide temperature ranges, small, rugged, inexpensive, and identifiable. In a multi-sensory environment, it is necessary both to identify the sensor and to retrieve the sensed information. The OFC SAW technology approach has been funded by NASA for possible inclusion in ground, space flight, and space exploration sensor applications. The purpose of this paper is to present the concept of encoding SAW-based sensors for use in a multiple-sensor environment. The emphasis will be on orthogonal frequency coded (OFC) devices overlaid with a form of time division multiplexing (TDM). It will be shown that in addition to the benefits of OFC such as enhanced processing gain and lower interrogation power spectral density (PSD), the TDM allows for a decrease in overlapping energy and therefore a decrease in intersensory collisions which are shown to cause peak ambiguity. This approach should be applicable to many different SAW-based sensors (such as temperature, pressure, liquid, gas, etc.), as well as allow for proper IDing. Measured device results are presented and compared with coupling of modes (COM) model predictions to demonstrate performance. This paper will discuss the use of SAW OFC in a temperature sensor application. Devices are then used in computer-simulated transceiver design, and the results of a prototype sensor system are discussed.","PeriodicalId":417077,"journal":{"name":"2009 IEEE International Conference on RFID","volume":"232 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115016554","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}
