Literature Review Title: A RESEARCH SURVEY: RFID SECURITY & PRIVACY ISSUE 
Chapter Title:  SECURITY & PRIVACY RISK 
1. Abstract of Cited Paper (BIB001):  Recently, new families of wireless ad hoc networks have emerged for specialized applications--- personal area networks. Wireless personal area networks (WPAN) is rapidly gaining popularity. A wide variety of traditional computing devices and embedded Internet appliances are networked around us. However, due to the broadcast nature of these networks and the heterogeneity of devices on these networks, new security problems will arise, because the different types of devices have different capabilities and security requirements. In this paper, an overview of security issues like attacks and its countermeasures for wireless personal area networks such as Bluetooth, RFID and wireless sensor networks has been provided.

Literature Review:
Widespread RFID deployment creates privacy risks for everyone. In this case, a reader would periodically broadcast a query and all the reader in the vicinity will respond to that reader. The reader will then forward these responses to the database. For instance, an unauthorized user can use the reader or buy another to communicate directly with the tag. So, RFID data can easily be attacked. There are various attacks like sniffing, tracking, spoofing, replay BIB001 and Denial of service cause security and privacy risk for RFID technology BIB002 .
