A RESEARCH SURVEY: RFID SECURITY & PRIVACY ISSUE <s> INTRODUCTION <s> The Auto-ID Center is developing low-cost radio frequency identification (RFID) based systems with the initial application as next generation bar-codes. We describe RFID technology, summarize our approach and our research, and most importantly, describe the research opportunities in RFID for experts in cryptography and information security. The common theme in low-cost RFID systems is that computation resources are very limited, and all aspects of the RFID system are connected to each other. Understanding these connections and the resulting design trade-offs is an important prerequisite to effectively answering the challenges of security and privacy in low-cost RFID systems. <s> BIB001 </s> A RESEARCH SURVEY: RFID SECURITY & PRIVACY ISSUE <s> INTRODUCTION <s> Radio Frequency IDentification (RFID), a technology for automatic object identification, has wide applications in many areas including manufacturing, healthcare, and transportation. 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. <s> BIB002 </s> A RESEARCH SURVEY: RFID SECURITY & PRIVACY ISSUE <s> INTRODUCTION <s> RFID technology is increasingly being deployed in ubiquitous computing environments for object tracking and localization. Existing tracking architecture usually assumes the use of a trusted server which is invulnerable to compromise by internal and external adversaries. However, maintaining such a trusted server is unlikely in the real world. In this paper, we consider the problem of adding privacy protection to object tracking systems built upon passive RFID tags, without relying on a trusted server assumption. Our protocol continues to protect user privacy in the event of partial compromise of a server. <s> BIB003
RFID is a system that facilitates the tracking of objects as well as people via a technology comprised of a reader, a Transceiver with decoder and a transponder (RF tag). RFID Journal magazine defines an RFID tag as "a microchip attached to an antenna that is packaged in a way that it can be applied to an object. A tag is a type of device that can be attached to a person or a manufactured object for the purpose of unique identification and a reader is an electronic device that broadcasts a radio signal to a tag, which then transmits its information back to the reader BIB001 . There are following components which define the RFID Tracking System:- • Determining location i.e. where the tag was read. • Determining time i.e. what time the tag was read. • The EPC (Electronic Product Code) is a unique identifier of the tagged object or person. Streams of RFID data records are defined in the form of EPC (Electronics Product Code), location (loc) and time (t) where each record indicates that an RFID reader in location (loc) has detected an object having EPC at time t. The path of an object is defined by loci, ti, which is a sequence of pair that is obtained by first grouping the RFID records by EPC and then sorting the records in each group by timestamps. A timestamp is the entry time of an object in location assuming that the object is staying in the same location until its new location is detected by another reader BIB002 . RFID is a wireless system that works in conjunction with an organization's information technology infrastructure to improve business processes  . The RFID tag cannot determine the time and location independently BIB003 . The RFID tag cannot maintain an internal clock to determine time by itself, not capture IP address or GPS coordinates to determine its location independently. RFID technology is used in many areas like medical, transportation, passport, library etc. for object identification. In today's scenario as of now, RFID tags are mostly used in proximity cards, automated toll-payment transponders and payment tokens. Previously as its readings are more accurate than (mostly manually operated) barcode systems, RFID tags can be integrated within the structure of packaging material or even within products.
