RFID TECHNOLOGY, PRIVACY AND SECURITY

Every day, people interact directly with a Radio Frequency Identification (RFID) device (tag), buying a product or accessing some desired place. The tag can then be interrogated via radio waves by an RFID reader to return a small amount of information, such as an identification code or personal data. Also, the RFID technology is very useful for supplying chain management, item tracking and other areas. At the same time, the RFID technology raises privacy and security issues. For example, applying RFID tags to individual items raises the possibility that the movement of these items can be tracked, or that individuals can be scanned to learn what items they carry. Many other examples can be named to illustrate problems arising from undesired uses of the RFID data. This paper presents some issues that can be very helpful for overcoming the above mentioned problems.
