On the Observability of RFID Data Privacy
Sozo Inoue, Yasunobu Nohara · 2009
In this paper, we discuss the observability of RFID (Radio Frequency IDentification) data privacy. RFID is a tech- nology that identifies objects and people with radio frequency. In the literature, a metric and a method for the privacy of RFID data, which is for publication to somewhere, are proposed, named LKC-privacy. Though this method is the first to propose RFID data privacy, there remains a problem that they do not consider a person is linked to multiple RFID tags. This leads to the risks that the published data leaks the information of who has the RFID tags, and the assumption that an adversary knows at most specific length of RFID log is too pessimistic. In this paper, we model a privacy model for representing this, and discuss its compatibility with LKC-privacy. I. INTRODUCTION
