Abstract

By integrating at a center and analyzing not only data accumulated in a single site but also data accumulated in distribution in a plurality of sites, macro information can be obtained. An aggregation unit of a site device of a plurality of remote sites extracts information contained in accumulated data to generate aggregated information. An aggregated information integration unit of a center device generates integrated aggregated information by integrating aggregated information which is received from each site and an approximate information generation unit generates approximate information which reproduces the contents of data of all the remote sites. Then, an analysis unit generates macro information based on the approximate information. This arrangement enables macro information as the whole system to be generated to high precision. In addition, the volume of communication between the site and the center at the time of data analysis can be reduced to ensure privacy protection.
