Document Type and Number:
WIPO Patent Application WO/2008/053578
Kind Code:
A1
Abstract:
An RFID group storage section (40) stores an RFID group structure. The RFID group
structure is a data structure of a set of RFIDs and is hierarchically structured
by associating the location and time read from an RFID tag with RFID-related information
in each of the RFIDs, by classifying the RFIDs depending on the readout location
and further classified depending on the readout time. A proximity degree evaluating
section (80) evaluates the degree of proximity between an RFID set of a first user
and an RFID set of a second user. A user classification section (82) classifies
the first user and the second user into the same group if the proximity degree is
smaller than a predetermined threshold value.
