Abstract

A system having a server and an information terminal of A which records A's personal information Pa and B's personal information Pb', an information terminal of B which records A's personal information Pa and B's personal information Pb′. B's information terminal generates a calculation result F(Pa′,Pb) via the calculation of Pa′ and Pb, sends F(Pa′,Pb) to a server. The server correlates B's identification tag with F(Pa′,Pb) and records it. A's information terminal forms F(Pa,Pb′) calculated via the calculation of Pb′ and Pa and sends F(Pa,Pb′) to the server. The server searches for a calculation result which matches F(Pa,Pb′) and by detecting a match between F(Pa′,Pb) and F(Pa,Pb′) detects B's identification tag which has been correlated with F(Pa′,Pb) and detected B's identification tag is sent to A's information terminal.
