Abstract
An RFID aggregate storage stores a radio-frequency ID aggregate structure. The RFID aggregate structure is an aggregated data structure of a plurality of RFIDs, in which each RFID is associated with a location and time read out from a RFID tag, and RFID related information, hierarchically constructed by classifying RFIDs based on the readout location and further by classifying them based on the readout time. A proximity evaluator evaluates the proximity between the first user's RF ID aggregate and the second user's RFID aggregate. A user classifier classifies the first user and the second user in one group when the proximity is smaller than a predetermined threshold value.
