PPS: Privacy-Preserving Statistics Using RFID Tags
As RFID applications are entering the daily life, many new security and privacy challenges arise. However, current research in RFID security focuses mainly on simple authentication and privacy-preserving identification. In this paper, the authors widen the scope of RFID security and privacy by introducing a new application scenario. The suggested application consists of computing statistics on private properties of individuals stored in RFID tags. The main idea is to compute global statistics while preserving the privacy of individual readings.
