RFID: opportunities and risks [Keynote Talk]
Frank Stajano (University of Cambridge, UK)

Abstract. Making RFID tags as ubiquitous as barcodes will enable machines to see and recognize any tagged object in their vicinity, better than they ever could with the smartest image processing algorithms. This opens many opportunities for "sentient computing" applications. However, in so far as the new capability has some of the properties of X-ray vision, this also opens the door to many potential abuses. With a view towards stimulating workshop discussion, I won't elaborate on technological solutions; instead I present a simple security policy model that addresses most privacy objections. Playing devil's advocate, I also indicate why it is unlikely that consumers will enjoy the RFID privacy they often vociferously demand.
