Title:
POSITION AUTHENTICATING SYSTEM, POSITIONING TERMINAL DEVICE, AND POSITION AUTHENTICATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/164096
Kind Code:
A1
Abstract:
A positioning terminal (2) transmits terminal position information (23) to a position authenticating device (5). The position authenticating device (5) acquires a digitized positioning signal (Da) and a positioning reinforcement signal (Ra) as data that are the same as data used by the positioning terminal device (2) to calculate a positioning position (Pa) and a positioning time (Tc) included in the terminal position information (23). On the basis of the acquired digitized positioning signal (Da) and positioning reinforcement signal (Ra), the position authenticating device (5) calculates a corresponding position (Pc) corresponding to the positioning position (Pa) included in the terminal position information (23) received from the positioning terminal (2), and a corresponding time (Tc) corresponding to the positioning time (Ta) included in the terminal position information (23), compares the corresponding position (Pa) with the positioning position (Pa)and compares the corresponding time (Tc) with the positioning time (Ta).
