AUTHENTICATING SERVER DEVICE, TERMINAL DEVICE, AUTHENTICATING SYSTEM AND AUTHENTICATING METHOD

摘要

It is an object to certify the principal of a subject person who brings about a certain event, for example, in addition to the certification of time, and/or a place of the event. A terminal device (200) transmits positioning information from a GPS satellite (103), and time and user's live body information to an authenticating server (300), and requests it to issue a certification code (104). The authenticating server (300) compares the received live body information with user reference data held in advance to carry out biometrics authentication. If the authenticating server (300) is successful in the biometrics authentication, it generates the certification code (104) in combination with the reference data used for the biometrics authentication, time, a hash value of a weather satellite image and the positioning information. The terminal device (200) receives the certification code (104) from the authenticating server (300) and outputs the received certification code (104) to a label, a photograph, and an IC (integrated circuit) tag, etc., for use.
