  Further, the analysis server 160 can analyze, for example, the movement history and the behavior history of the plurality of users 12 and extract a behavior pattern unique to each transportation means. For example, when focusing on a certain store, it is possible to analyze the difference in purchasing characteristics between a customer who visits the store by train and a customer who visits the store by foot. It is difficult to perform such an analysis using only the location registration information 302, and it is also difficult to perform such an analysis using only the log information 402. Such an analysis becomes possible only by merging the location registration information 302 and the log information 402 based on the SIM authentication information 502.
