Hereinafter, an information providing system, an information providing method, and a computer program according to embodiments will be described with reference to the drawings.

FIG. 1 is a schematic diagram showing an outline of an ETC system.
FIG. 1 shows the vehicle 100 entering the toll gate 200. In the toll gate 200, an antenna device 201, a gate device 202, and a toll gate server 203 are installed. Antenna device 201 communicates with vehicle 100. The gate device 202 controls the exit of the vehicle 100 at the toll gate 200 by opening and closing the gate. The toll booth server 203 manages traffic of the vehicle 100 at the toll booth 200. The host server 300 (information providing server) collects information on the road usage fee of the passed vehicle 100 from the toll gate server 203. Hereinafter, for convenience of explanation, each device installed in the toll booth 200 and the upper server 300 are referred to as an ETC system.

  The vehicle 100 performs wireless communication with the antenna device 201 while traveling on the ETC lane in front of the toll gate. The ETC lane is a passage provided for aligning vehicles entering the toll gate in front of the gate device 202. At the toll booth that supports the ETC system, the road branches to the ETC lane before the toll booth and merges again through the toll booth. FIG. 1 shows one such ETC lane.

  The vehicle 100 transmits user information in wireless communication with the antenna device 201. Specifically, the user information is information related to the user necessary for the settlement of the road usage fee by the ETC system. User information is transmitted by an ETC vehicle-mounted device (not shown) mounted on the vehicle 100. The ETC in-vehicle device is associated with the vehicle on a one-to-one basis, and is fixedly installed on the corresponding vehicle. The ETC on-vehicle device stores vehicle information related to the installed vehicle in advance. For example, the vehicle information includes information such as a vehicle number and a vehicle type. In addition, card information such as a credit card number and expiration date is recorded in advance on an ETC card inserted into the ETC on-vehicle device, and history information such as travel history and usage time is appropriately recorded. The ETC vehicle-mounted device generates user information based on information such as card information and history information read from an ETC card inserted in the own device, and vehicle information stored in advance in the own device.

  The antenna device 201 receives user information transmitted from the vehicle 100. The antenna device 201 transmits the received user information to the toll gate server 203. The toll gate server 203 receives the user information transmitted from the antenna device 201. The toll gate server 203 calculates the road usage fee of the vehicle 100 based on the user information acquired from the antenna device 201. The toll gate server 203 generates detailed information regarding the calculated road usage fee and transmits it to the vehicle 100. The toll gate server 203 permits the passage of the vehicle 100 by transmitting this detailed information, and instructs the gate device 202 to open the gate.

  In FIG. 1, the toll gate server 203 acquires user information from one illustrated antenna device 201, but in reality, user information is obtained from the antenna devices installed in all ETC lanes of the toll gate 200. To get. The toll gate server 203 performs traffic management for each ETC lane based on the user information acquired from each antenna device.

  The host server 300 receives the detailed information transmitted from the toll gate server 203. In FIG. 1, the upper server 300 acquires the detailed information from one tollgate server 203 shown in the figure, but actually acquires the detailed information from all tollgate servers of the tollgate included in the management target. The host server 300 transmits the acquired detailed information to a credit card company (not shown) and requests an approval for payment of the road usage fee.

  The above is the outline of the collection of road usage fees by the ETC system. Conventionally, the detailed information transmitted from the ETC system is displayed on the other in-vehicle devices such as the in-vehicle navigation device by the ETC in-vehicle device, so that the detailed information is provided to the user. Therefore, there is a possibility that detailed information as personal information may be leaked to other passengers. On the other hand, the terminal device of this embodiment acquires detailed information instead of said vehicle equipment. For example, a mobile terminal such as a smartphone or a tablet is used as the terminal device of the embodiment. By using such a terminal device, the user can confirm the detailed information while ensuring confidentiality.

Drawing 2 is a schematic diagram showing an outline of acquisition of detailed information by terminal unit 3 of an embodiment.
In the description of FIG. 2, the same reference numerals as those in FIG.

  Reference numeral 400 in FIG. 2 indicates that the beacon device 1 and the ETC vehicle-mounted device 2 are mounted on the vehicle 100. In general, a beacon device refers to a device that transmits a beacon signal for notifying predetermined information. In the present embodiment, the beacon device 1 is associated with a specific ETC vehicle-mounted device 2 in advance, and is installed in the same vehicle 100 as the corresponding ETC vehicle-mounted device 2. The beacon device 1 transmits the identification information of the corresponding ETC vehicle-mounted device 2 as a beacon signal.

  The ETC vehicle-mounted device 2 performs wireless communication with the antenna device 201 installed at the road toll gate. For example, the ETC vehicle-mounted device 2 performs wireless communication in a communication mode called DSRC (Dedicated Short Range Communication) in the 5.8 GHz band. The ETC vehicle-mounted device 2 executes various processes relating to the road usage fee settlement through communication with the ETC system. For example, the ETC vehicle-mounted device 2 generates user information based on information such as vehicle information and card information. The ETC on-vehicle device 2 transmits the generated user information to the antenna device 201 in response to a user information transmission request notified from the antenna device 201. Moreover, the ETC onboard equipment 2 records the information regarding the road usage fee transmitted from the antenna device 201 on the ETC card.

  The terminal device 3 is a terminal device used by a user for confirming detailed information. For example, the terminal device 3 is a mobile terminal such as a smartphone, a tablet, or a mobile phone. The terminal device 3 can perform wireless communication with the host server 300 via a wireless LAN or a public telephone line network. The terminal device 3 is preinstalled with a dedicated application for acquiring detailed information (hereinafter referred to as “detailed application”). The detail application is activated by the user of the terminal device 3. The detail application does not interfere with other operations of the terminal device 3 and user operations, and can operate in the background.

  The terminal device 3 receives the beacon signal transmitted from the beacon device 1, and acquires the detailed information from the higher-level server 300 when the received beacon signal indicates the ETC vehicle-mounted device 2 associated with the own device in advance.

  Hereinafter, the configuration of the terminal device 3 of the embodiment will be described in detail.

FIG. 3 is a functional block diagram illustrating functional configurations of the beacon device 1 and the terminal device 3 according to the embodiment.
The beacon device 1 includes a CPU (Central Processing Unit), a memory, an auxiliary storage device, and the like connected by a bus, and executes a beacon device program. Beacon device 1 functions as a device provided with beacon information storage part 11 and beacon signal transmission part 12 by execution of a beacon device program. Note that all or part of each function of the beacon device 1 may be realized by using hardware such as an application specific integrated circuit (ASIC), a programmable logic device (PLD), or a field programmable gate array (FPGA). The beacon device program may be recorded on a computer-readable recording medium. The computer-readable recording medium is, for example, a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, or a storage device such as a hard disk built in the computer system. The beacon device program may be transmitted via a telecommunication line.

  The beacon information storage unit 11 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The beacon information storage unit 11 stores beacon information in advance. The beacon information is information transmitted as a beacon signal from the own device. The beacon information is generated by encrypting predetermined information and stored in the beacon information storage unit 11 in advance. The beacon information in the present embodiment is information obtained by encrypting the identification information of the ETC in-vehicle device 2 corresponding to the own device.

  The beacon signal transmission unit 12 transmits the beacon information stored in the beacon information storage unit 11 as a beacon signal. In the present embodiment, the beacon signal transmission unit 12 always transmits a beacon signal as long as the power is turned on. Therefore, the wireless communication function of the beacon signal transmission unit 12 uses a short-range wireless communication technology that can operate with low power, such as BLE (Bluetooth (registered trademark) Low Energy). By using such a low-power wireless communication technology, the beacon signal transmission unit 12 may be configured to operate with a built-in power source such as a battery. With this configuration, the beacon device 1 can operate even when the engine of the vehicle 100 is stopped. In addition, a storage battery that can be charged by the engine operation of the vehicle 100 may be used as the built-in power source of the beacon signal transmission unit 12. By being configured in this way, the beacon device 1 can be used continuously semipermanently.

  As described above, the beacon device 1 is a device having a function of transmitting beacon information registered in advance in its own device as a beacon signal. Such a beacon device 1 does not require cooperation with other devices and operates by itself. Therefore, the user does not need a new dedicated ETC vehicle-mounted device 2 when introducing the beacon device 1 and can install the beacon device 1 later on the vehicle 100 equipped with the existing ETC vehicle-mounted device 2. It is.

Next, the configuration of the terminal device 3 will be described.
The terminal device 3 includes a CPU, a memory, an auxiliary storage device, and the like connected by a bus, and executes a terminal device program. The terminal device 3 functions as a device including the upper server communication unit 31, the storage unit 32, the beacon signal reception unit 33, and the application control unit 34 (information acquisition unit) by executing the terminal device program. All or some of the functions of the terminal device 3 may be realized using hardware such as an ASIC, PLD, or FPGA. The terminal device program may be recorded on a computer-readable recording medium. The computer-readable recording medium is, for example, a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, or a storage device such as a hard disk built in the computer system. The terminal device program may be transmitted via a telecommunication line.

  The upper server communication unit 31 is configured using a communication interface for connecting to a wireless communication network. For example, the host server communication unit 31 is provided by a wireless communication line such as a wireless LAN standardized by Wi-Fi (Wireless Fidelity) (registered trademark) or a 3G (3rd Generation mobile communication system). Connect to a wireless communication network.

  The storage unit 32 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 32 stores key information necessary for decrypting the beacon signal in advance. The storage unit 32 stores in advance an execution module of the detailed application.

  The beacon signal receiving unit 33 receives a beacon signal transmitted from the beacon device 1. The beacon signal receiving unit 33 outputs the received beacon signal to the application control unit 34.

  The application control part 34 is a function part produced | generated by execution of a detailed application. The application control unit 34 is generated by the CPU reading and executing the detailed application execution module stored in the storage unit 32 on the memory. The application control unit 34 acquires the beacon signal received by the beacon signal receiving unit 33. The application control unit 34 decrypts the acquired beacon signal using the key information stored in the storage unit 32. The application control unit 34 acquires beacon information by decoding the beacon signal. When the beacon information can be normally acquired, the application control unit 34 accesses the upper server 300 via the upper server communication unit 31 and acquires the user detailed information from the upper server 300.

  As described above, the terminal device 3 accesses the host server 300 based on the beacon signal transmitted from the beacon device 1, thereby suppressing the detailed information from being acquired by the terminal device of another user. it can. As described above, this control requires transmission of a beacon signal by the beacon device 1 and decoding of the beacon signal by the terminal device 3. Therefore, in order to realize the above function, a prior work (hereinafter referred to as “preliminary setting”) related to transmission / reception of a beacon signal to the beacon device 1 and the terminal device 3 is required.

FIG. 4 is a flowchart showing a pre-setting flow for the beacon device 1 and the terminal device 3.
Here, the flow of the presetting will be described by taking as an example a case where a beacon device 1 is newly added to a vehicle equipped with the ETC in-vehicle device 2 beforehand. First, beacon device 1 is installed in a user's vehicle (Step S101). For example, the beacon device 1 is installed in a user's vehicle by a maintenance company (hereinafter referred to as “trader”). The trader generates key information unique to the installed beacon device 1 (step S102). Moreover, a trader produces | generates the identification information of the ETC onboard equipment 2 matched with the beacon apparatus 1 (step S103). For example, the trader acquires a vehicle number included in the vehicle information. The trader generates a UUID (Universally Unique Identifier) based on the acquired vehicle number. The UUID is unique identification information without duplication.

  The trader generates beacon information based on the key information generated in step S102 and the identification information generated in step S103 (step S104). Specifically, the trader generates beacon information by encrypting the generated identification information using key information. The trader registers the generated beacon information in the beacon device 1 (step S105). With this operation, the beacon information is stored in the beacon information storage unit 11 of the beacon device 1.

  Pre-setting of the beacon device 1 is completed by the above processing. When the presetting is completed, the beacon device 1 starts transmitting a beacon signal. Specifically, the beacon signal transmission unit 12 acquires the beacon information registered by the trader from the beacon information storage unit 11. The beacon signal transmission unit 12 converts the acquired beacon information into a beacon signal and transmits it.

  On the other hand, the trader provides the user of the terminal device 3 with the key information generated for the user's beacon device 1. The trader provides key information using a means that does not leak to a third party. For example, the trader may mail the storage medium on which the key information is recorded by a confidential mailing means, or send the key information by a confidential communication means using authentication, encryption, or the like. Also good. The user registers the key information provided by the supplier in the terminal device 3 (step S106). With this operation, the key information is stored in the storage unit 32 of the terminal device 3.

  Pre-setting of the terminal device 3 is completed by the above processing. When the presetting is completed, the user activates the detail application. The terminal device 3 starts receiving the beacon signal transmitted from the beacon device 1 by the activation of the detailed application.

FIG. 5 is a sequence diagram showing a flow of collecting the road usage fee by ETC.
When the user's vehicle 100 approaches the toll gate 200, the ETC on-board unit 2 starts communication with the antenna device 201 installed at the toll gate 200. When communication with the antenna device 201 is started, the ETC vehicle-mounted device 2 acquires card information and vehicle information, and generates user information. The ETC vehicle-mounted device 2 transmits the generated user information to the toll gate server 203 via the antenna device 201 (step S201).

  The toll gate server 203 receives the user information transmitted from the ETC in-vehicle device 2 via the antenna device 201 (step S202). The toll gate server 203 calculates a road usage fee for the vehicle 100 based on the user information (step S203). The toll booth server 203 generates detailed information related to road usage of the vehicle 100 based on the calculated road usage fee, and transmits it to the upper server 300 (step S204).

  The upper server 300 receives the detailed information transmitted from the toll gate server 203 (step S205). The host server 300 accumulates the detailed information received in this way in its own device (step S206).

6, 7, and 8 are sequence diagrams illustrating a flow in which the terminal device 3 according to the embodiment acquires detailed information.
First, the beacon device 1 transmits a beacon signal (step S301). Here, the user activates the detailed application in the terminal device 3 and moves the terminal device 3 within the wireless communication range of the beacon device 1. The terminal device 3 receives the beacon signal transmitted from the beacon device 1 via the beacon signal receiving unit 33 (step S302).

  The application control unit 34 acquires a beacon signal transmitted from the beacon device 1 and acquires key information from the storage unit 32. The application control unit 34 decrypts the acquired beacon signal based on the acquired key information (step S303). The application control unit 34 determines whether or not the beacon information has been normally acquired by decoding the beacon signal (step S304). When it determines with beacon information not being acquired normally (step S304-NO), the application control part 34 determines with the beacon apparatus 1 which transmitted the beacon signal not being an apparatus matched with the own apparatus. In this case, the application control unit 34 returns to step S302 and continues receiving beacon signals.

  On the other hand, when it determines with beacon information having been acquired normally (step S304-YES), the application control part 34 transmits authentication information to the high-order server 300 (step S305). The authentication information is information necessary for accessing the upper server 300, and is, for example, a user ID and a password, and is input by a user operation. In this way, by transmitting / receiving beacon information in which identification information of the ETC on-vehicle device 2 is encrypted, the terminal device 3 can be operated based on a beacon signal transmitted from a specific beacon device 1.

  The upper server 300 receives the authentication information transmitted from the terminal device 3 (step S306). The upper server 300 authenticates the user of the terminal device 3 that has transmitted the authentication information based on the authentication information (step S307). The upper server 300 transmits the authentication result to the terminal device 3 that is the transmission source of the authentication information (step S308). Here, the host server 300 may be configured to maintain the authentication state of the terminal device 3 for a predetermined period thereafter when the transmission source user can be authenticated. By maintaining this authentication state, the user can omit the operation of inputting authentication information to the terminal device 3 in the next access to the host server 300. For example, the user can access the upper server 300 only by moving the terminal device 3 into the wireless range of the beacon device 1.

  The terminal device 3 receives the authentication result transmitted from the upper server 300 (step S309). Based on the received authentication result, the application control unit 34 determines whether the access of the own device has been authenticated (step S310). If it is determined that the access of the own device has not been authenticated (step S310—NO), the application control unit 34 notifies the user of an authentication error (step S311), and returns to step S302.

  On the other hand, when it determines with the access of the own apparatus having been authenticated (step S310-YES), the application control part 34 produces | generates the request information transmitted to the high-order server 300 (step S312). The request information is information for requesting the higher order server 300 to transmit the detailed information of the user. The application control unit 34 includes user identification information in the request information. The application control unit 34 transmits the generated request information to the upper server 300 (step S313).

  The upper server 300 receives the request information transmitted from the terminal device 3 (step S314). The host server 300 acquires the detailed information of the user indicated by the request information from the detailed information accumulated in its own device (step S315). The upper server 300 transmits the acquired detailed information to the terminal device 3 that is the transmission source of the request information (step S316).

  The terminal device 3 receives the detailed information transmitted from the higher order server 300 (step S317). The application control unit 34 displays the received detailed information on the display unit (not shown) of its own device (step S318).

  The terminal device 3 according to the embodiment configured as described above acquires detailed information from the upper server 300 when receiving a beacon signal transmitted from the beacon device 1 associated in advance. When the terminal device 3 acquires such detailed information, the user can confirm the detailed information so that it is not seen by other passengers. Therefore, the fee specification inquiry system including the beacon device 1 and the terminal device 3 of the embodiment can provide the fee details to the user while ensuring confidentiality.

  Moreover, the beacon device 1 in the embodiment transmits beacon information in which user information is encrypted as a beacon signal. And the terminal device 3 which receives a beacon signal acquires detailed information from the high-order server 300, when the received beacon signal can be decoded normally. Key information for generating beacon information is set only in the terminal device 3 corresponding to the beacon device 1. Therefore, the terminal device 3 according to the embodiment can suppress a third-party terminal device from acquiring the detailed information illegally.

  Conventionally, there is a service that can inquire detailed information on the Internet. However, in such a service, the user has to input authentication information every time an inquiry is made. On the other hand, the terminal device 3 of the embodiment accesses the upper server 300 only when the beacon information can be acquired from the beacon device 1 associated in advance. It can be considered that the terminal device 3 that performs such access is already authenticated at the time of accessing the upper server 300. Therefore, the upper server 300 maintains the authentication state of the terminal device 3 that performs such access for a predetermined period, so that the user does not need to input authentication information for each access to the upper server 300. Therefore, the terminal device 3 according to the embodiment can realize both the reduction of the complexity of the user's operation in acquiring the detailed information and ensuring the confidentiality of the detailed information.

<Modification>
The aspect in which the detailed information is provided to the terminal device 3 is not limited to the aspect in which the terminal device 3 acquires from the upper server 300. For example, the detailed information may be push-distributed from the upper server 300. Push distribution is an information distribution method in which a server actively transmits information to a client regardless of the information acquisition request of the client. In this case, the terminal device 3 transmits request information for notifying that the detailed information is acquired by push delivery to the upper server 300. In that case, the terminal device 3 may include information for specifying distribution conditions such as information to be distributed for push distribution and distribution timing in the request information. The host server 300 push-distributes the user's detailed information according to the distribution condition indicated by the request information.

  Further, the information provided to the user by the above method is not limited to the detailed information. For example, when the ETC vehicle-mounted device 2 has a function as a DSRC vehicle-mounted device, the terminal device 3 can acquire information regarding various traffics provided by the ITS system. For example, the terminal device 3 can acquire information on road congestion and accidents, information on coupons that can be used in the service area, and the like. For example, it is possible to automatically distribute electronic coupons, congestion information, and traffic information that can be used in a service area at the destination from a host system to a smartphone.

  The detailed information may be transmitted from the upper server 300 in any manner. For example, the detailed information may be transmitted in the form of HTML (Hyper Text Markup Language) that can be displayed on a web browser, or may be transmitted in the form of an e-mail.

  In the above-described embodiment, the description application is described as being activated by the user, but may be automatically activated by the terminal device 3. For example, in this case, a function for acquiring beacon information from a beacon signal is provided other than the detailed application. Specifically, for example, the OS (Operating System) of the terminal device 3 is caused to execute the processes of steps S303 and S304 in FIG. When the OS of the terminal device 3 has successfully acquired the beacon information from the beacon signal, the OS determines whether the detailed application is activated. When the detail application is not activated, the OS of the terminal device 3 activates the detail application using the acquired beacon information as input information.

  According to at least one embodiment described above, a beacon signal receiving unit that receives a beacon signal transmitted from a beacon device and a beacon signal that is received in advance by the beacon signal received by the beacon signal receiving unit. When it is a beacon signal transmitted from the apparatus, it is possible to provide detailed information to the user while ensuring confidentiality by having an information acquisition unit that acquires information about the user from the information providing server. .

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
