“…Specific issues of preventing unauthorized RFID readouts and consequently increasing RFID security are beyond the scope of this paper, although, a number of different techniques that might prevent misuse of RFID have been proposed, e.g. [3,5,10,21,23,25]. Our main interest, however, is to examine a potential loss of privacy as a result of authorized RFID readouts, and in particular, how a large-scale deployment of an RFID system could impact the privacy of its users.…”
