Problems solved by technology

In addition, the ID code of the engine electronic anti-theft system is very complicated and it is difficult to generate a spare, but the key will fall into the hands of a third party when the spare key is made or immediately before delivery, so it cannot be called absolute security

Embodiment 1

[0096] figure 1 It is a figure which shows the outline|summary of the authentication system 1 of Example 1. As shown in the figure, the authentication system 1 of the first embodiment is composed of an in-vehicle device 10 mounted on a vehicle, a portable terminal device 20 carried by a passenger, and a server device 30 connected to the network of the portable terminal device 20 . In addition, this figure shows the procedure of "pairing" performed when the in-vehicle device 10 and the portable terminal device 20 establish communication using Bluetooth (registered trademark).

[0097] In this manner, in order to perform communication using Bluetooth (registered trademark), it is necessary to exchange, for example, the same authentication key called a PIN (Personal Identity Number) code between communication devices to mutually authenticate target devices. However, at present, the exchange of the PIN code is performed by the user manually inputting the PIN code displayed on the...

Embodiment 2

[0133] Figure 4 It is a figure which shows the outline|summary of the authentication system 1a of Example 2. As shown in this figure, the vehicle-mounted device 10a generates a PIN code (refer to Figure 4 (1)), generate a QR code (registered trademark) including the generated PIN code, and display the generated QR code (registered trademark) (see Figure 4 (2)).

[0134] Next, the portable terminal device 20a reads the QR code (registered trademark) displayed on the vehicle-mounted device 10a (see Figure 4 (3)) to obtain a PIN code from the read QR code (registered trademark) (see Figure 4 (4)). Then, the portable terminal device 20a transmits the obtained PIN code to the vehicle-mounted device 10a (see Figure 4 (5)), the in-vehicle device 10a having received the PIN code performs judgment on the received PIN code and the Figure 4 The verification process of whether the PIN code generated in (1) matches or not (refer to Figure 4 (6)).

[0135] Thus, by omitting ...

Embodiment 3

[0142] Figure 7 It is a figure which shows the functional structure example of the Example of the authentication system which includes the authentication apparatus of Example 3. Such as Figure 7 As shown, the authentication system of this embodiment is composed of an authentication device 100 and a portable terminal 200 . The authentication device 100 includes an authentication unit 110 for performing user authentication control processing, a storage unit 120 for storing data required for user authentication control processing, and a communication unit including a Bluetooth (registered trademark) device and having a Bluetooth (registered trademark) communication function. 150. An input unit 160 for accepting an input from a user, and a display unit 170 for displaying information notified to the user, etc. are constituted. The authentication unit 110 is composed of a verification unit 130 and an information unit 140 .

[0143] In addition, the portable terminal 200 is a te...

Abstract

An on-vehicle device generates an authentication key and displays, on a display, a two-dimensional code including the generated authentication key and URL indicating a predetermined WEB page on the network. A mobile terminal device reads the two-dimensional code via an imaging unit so as to obtain the authentication key and the URL from the two-dimensional code and downloads a communication program for making a communication with the on-vehicle device from a WEB page relating to the URL. The downloaded communication program is operated so as to transmit the authentication key to the on-vehicle device.

Description

technical field [0001] The present invention relates to an authentication method, an authentication system, a vehicle-mounted device, and an authentication device. Background technique [0002] In recent years, car navigation systems have become popular, and cars are generally equipped with in-vehicle devices capable of viewing music and video, displaying navigation information, and the like. In addition, such an in-vehicle device can communicate with a portable terminal device such as a mobile phone or a PDA (Personal Digital Assistant) carried by a passenger, and perform data transmission and reception between the portable terminal device and the in-vehicle device. [0003] In this way, when communicating between communication devices, a wireless communication standard called Bluetooth (Bluetooth, registered trademark) is known. Bluetooth (registered trademark) is a wireless communication standard using a frequency band of 2.4 GHz, which enables wireless communication wit...
