Based on the group set identification information acquired, one group set is selected from the plurality of group sets (S04). In the selected group set, the upper groups including the group to which the member code acquired is allocated are traced up to the hierarchical level acquired (S06, S07) and a specific identification number contained in the group of the hierarchical level acquired is extracted (S08). <P>COPYRIGHT: (C)2004,JPO |
