Problems solved by technology

In this application, even if the location measurement terminal can calculate a reliable current location, if the location measurement terminal transmits location information indicating a location different from the calculated current location to the location that receives the location information and performs billing processing If the information acquisition device is used, the billing cannot be performed accurately
[0010] In this way, in a system in which the position information acquisition device acquires the position calculated by the position measurement terminal and performs predetermined processing such as billing, it is not enough for the position measurement terminal to be able to accurately calculate the position.

Embodiment approach 1

[0036] Hereinafter, embodiments of the present disclosure will be described based on the drawings. Such as figure 1 As shown, the position information authentication system 1 according to Embodiment 1 includes an authentication center device 100 , an on-vehicle device 200 corresponding to the position measurement terminal of the present disclosure, and a roadside device 300 corresponding to the position information acquisition device of the present disclosure.

[0037] (Schematic structure of the positional information authentication system 1)

[0038] The authentication center device 100 includes a monitoring station device 110 , an authentication center processing device 120 , and a master control station device 130 . In addition, below, the device and the processing device are omitted, the monitoring station device 110 is referred to as the monitoring station 110 , the authentication center processing device 120 is referred to as the authentication center 120 , and the mai...

Embodiment approach 2

[0104] Next, Embodiment 2 will be described. In addition, in the following description of Embodiment 2, elements with the same reference numerals as those used up to now have the same reference numerals as those in the preceding embodiments except when specifically mentioned. same. In addition, when only a part of the configuration is described, the embodiments described above can be applied to the other parts of the configuration.

[0105] In Embodiment 2, the roadside machine 300A is as Figure 8 As shown, a satellite receiving unit 330 is provided. The satellite receiving unit 330 corresponds to the acquisition device side satellite receiving unit of the present disclosure. In addition, in Embodiment 2, a part of processing of the control unit 320A is different from that of the control unit 320 in Embodiment 1. use Figure 9 , Figure 10, and the processing of the control unit 320A will be described. The control unit 320A executes at a fixed GPS wave acquisition cycl...

Deformed example 1

[0123] (Modification 1, Modification 2)

[0124] For example, in the aforementioned embodiment, the H matrix and parity data are used as input keys of the hash function to create a hash value and a comparison hash value (authenticated creation unit: S10, comparison data creation unit: S100). However, the present invention is not limited thereto, and a hash value may be created and compared by making the input key of the hash function only an H matrix (modification 1). In addition, instead of the H matrix as the encryption key, the SEED value as the key creation data may be used as an input key of a hash function to create a hash value and compare the hash values ​​(modification 2).
