Abstract: To process the raw data for getting the effective event is the most basic and most important step in RFID middleware. First, this paper summarizes the characteristics of RFID data and presents the RFID middleware model based on data processing center; then focus on the study of the process for leakage read, more read, and dirty read; finally proposes and implements algorithms.
