RFID technology, privacy and security

Every day, people interact directly with a Radio Frequency Identification (RFID) device (tag), buying a product or to access at desire 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 a personal data. Also, the RFID technology is very useful for supply chain management, item tracking and other areas. At the same time, 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 another examples can be named to illustrated problems of undesired used of RFID data. In this paper are presented some issues related to overcome above problems. .
