PROBLEM TO BE SOLVED: To designate a retrieved person while authenticating a retrieving person by a simpler operation in the position retrieval. SOLUTION: A retrieving person 1 know the position of a retrieved person by a simple operation to input only an access code. A request sent from a mobile communication terminal 10 with the access code inputted thereto to a WWW server unit 51 contains a UID unique to the communication terminal 10, and hence the validity of the retrieving person 1 can be checked, based on whether a combination of the access code with the UID agrees with a previously registered one. The UID is to be described by a gateway unit 12 based on the telephone number of the mobile communication terminal 10, but the telephone number is generally hardly forged and hence it may be very difficult to forge the UID. Thus, the authentication of the retriever has a higher reliability using the UID instead of the ID and password the user manually inputs as before. COPYRIGHT: (C)2005,JPO&NCIPI
