1. A method of operating a server for providing a network service, said method comprising:
- receiving a first hash value F(Pa′
, Pb) from an information terminal of a user B having a first database containing personal information Pa′
of a user A and personal information Pb of said user B, said first hash value being generated by a hash function applied to a connection of said personal information Pa′ and
said personal information Pb;
correlating an identification tag of said user B with said first hash value F(Pa′
, Pb), said identification tag of said user B uniquely identifying said user B in said network service, and memorize said identification tag of said user B and said first hash value F(Pa′
, Pb);
receiving a second hash value F(Pa, Pb′
) from an information terminal of said user A having a second database containing personal information Pa of said user A and personal information Pb′
of said user B, said second hash value being generated by a hash function applied to a connection of said personal information Pa and said personal information Pb′
, andsearching for a hash value which is equal to said second hash value F(Pa, Pb′
) and detect said identification tag of said user B by detecting said first hash value F(Pa′
, Pb), which is equal to and said second hash value F(Pa′
, Pb), andsending said identification tag of said user B to said information terminal of said user A on a detection of said first hash value F(Pa′
, Pb), which is equal to said second hash value F(Pa, Pb′
).

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.
