[0009] In recent years, attempts have been made to utilize data acquired while a vehicle is traveling (driving data). By using the driving data collected from a vehicle as big data, it is possible to provide various services. It is expected that this will make it possible to provide information about the vehicle to the public. However, driving data may contain information that may affect privacy protection if linked to the driver. For this reason, attempts are being made to use collected driving data only with the consent of users (prescribed users) who own or have the right to use the vehicle.

[0010] However, the driver of the vehicle is not necessarily the specified user. For example, the vehicle may be driven by a family member or acquaintance of the specified user. In such a case, the accuracy of the driving data collected from the vehicle may be impaired. As an example, when driving data collected from a vehicle driven by a user of the same generation or sex as the specified user is requested, if driving data is collected from a vehicle driven by a family member or acquaintance of a different generation or sex from the specified user, driving data that does not satisfy the request will be collected. As a result, the accuracy of the collected driving data may be impaired. Therefore, a measure to ensure the accuracy of the driving data collected from the vehicle is required.

[0011] Therefore, in the information processing device according to the present disclosure, the control unit acquires vehicle data including driving data and driver information from the vehicle. As an example, the driving data may include data acquired while the vehicle is traveling, such as the vehicle's position, the vehicle's driving speed, the vehicle's traveling direction, the vehicle's behavior, the vehicle's starting point, the vehicle's destination, the vehicle's planned driving route, the state of the on-board equipment, and images captured by the on-board camera. In addition, the driver information is information required to verify the identity of a specific user and the driver, such as the vehicle's driver's biometric information and / or the driver's driving characteristics. In addition, the control unit may acquire the above-mentioned vehicle data by communicating with a device mounted on the vehicle through a network.

[0012] The control unit verifies the identity of a specific user associated with the vehicle and the driver of the vehicle based on the driver information included in the vehicle data acquired from the vehicle. The specific user is a user who has consented to the use of driving data acquired from the vehicle driven by the specific user, for example, a user who has ownership or use rights of the vehicle. Verification of the identity of the driver and the specific user may be performed based on biometric information and / or information indicating driving characteristics included in the driver information. In this case, the information processing device may include a storage unit that associates the biometric information and / or information indicating driving characteristics of the specific user with the vehicle and stores it. Then, the control unit may verify the identity of the driver and the specific user by collating the biometric information and / or information indicating driving characteristics included in the driver information with the biometric information and / or information indicating driving characteristics stored in the storage unit.

[0013] The control unit determines the validity of the driving data included in the vehicle data according to the verification result of the identity between the driver and the specified user. As an example, if the verification of the identity between the driver and the specified user is successful (for example, if the matching between the biometric information and / or the information indicating the driving characteristics included in the driver information and the biometric information and / or the information indicating the driving characteristics stored in the storage unit is successful), the control unit may determine that the driving data included in the vehicle data is valid. On the other hand, if the verification of the identity between the driver and the specified user fails (for example, if the matching between the biometric information and / or the information indicating the driving characteristics included in the driver information and the biometric information and / or the information indicating the driving characteristics stored in the storage unit is failed), the control unit may determine that the data acquired from the vehicle is not valid.

[0014] According to the information processing device of the present disclosure, it is possible to determine whether or not the driving data acquired by a vehicle in motion is data obtained when a specific user is driving. As a result, when, for example, driving data of a vehicle driven by a user of the same generation or gender as the specific user is requested, it is possible to collect only driving data that satisfies the request. As a result, it is possible to ensure the accuracy of the collected driving data.

[0015] The information processing device according to the present disclosure may be a server connected to a device mounted on a vehicle through a network. In this case, the processor of the server corresponds to the control unit. Note that verification of the identity of the driver and the specified user and determination of the validity of the data may be performed in the vehicle (a device mounted on the vehicle). In this case, the vehicle may transmit only data determined to be valid to a device outside the vehicle (e.g., a server, etc.) through the network.

[0016] Specific embodiments of the present disclosure will be described below with reference to the drawings. Unless otherwise specified, the hardware configuration, module configuration, functional configuration, and the like described in the following embodiments are not intended to limit the technical scope of the disclosure to only those.

[0017] <Embodiment> An embodiment of the present disclosure will be described with reference to the drawings. In the embodiment, an example in which an information processing device according to the present disclosure is applied to a vehicle system will be described. The vehicle system is a system that collects data required to provide a predetermined service from a vehicle.

[0018] (Vehicle system overview) Fig. 1 is a diagram showing an overview of a vehicle system in this embodiment. The vehicle system in this embodiment includes an in-vehicle device 10 mounted on a vehicle 1 and a server 2. In the example shown in Fig. 1, only one in-vehicle device 10 (vehicle 1) is shown, but the vehicle system may include multiple in-vehicle devices 10 (vehicles 1).

[0019] The vehicle 1 is a probe vehicle for collecting driving data. The vehicle 1 is a vehicle that can be driven by a specific user. The specific user is a user who has consented to the collection of driving data in advance, for example, a user who has ownership or use rights of the vehicle 1. The in-vehicle device 10 has a function of collecting data (driving data) of the vehicle 1 while it is traveling. The driving data includes, for example, the position of the vehicle 1, the driving speed of the vehicle 1, the traveling direction of the vehicle 1, the behavior of the vehicle 1, the departure point of the vehicle 1, the destination of the vehicle 1, the planned driving route of the vehicle 1, the state of the equipment mounted on the vehicle 1, and images captured by a camera mounted on the vehicle 1.

[0020] In addition to the above-mentioned functions, the in-vehicle device 10 of this embodiment has a function of acquiring information on the driver of the vehicle 1 (driver information). Furthermore, the in-vehicle device 10 of this embodiment also has a function of generating vehicle data based on the driving data and the driver information, and transmitting the generated vehicle data to the server 2. The "driver information" here is information used to verify the identity of the driver of the vehicle 1 with a specified user. In this embodiment, the driver's biometric information is used as the driver information. The biometric information may be at least one of the driver's face, iris, auricle, voiceprint, palm shape, fingerprint, etc.

[0021] The server 2 has a function of analyzing the driving data included in the vehicle data received from the in-vehicle device 10 and providing a predetermined service according to the analysis result. As one example, the server 2 generates road traffic information by analyzing the position information and speed information included in the driving data, and provides the generated road traffic information to other vehicles. As another example, the server 2 generates tourist spot information around the destination or the planned driving route by analyzing the destination or the planned driving route included in the driving data, and provides the generated tourist spot information to the vehicle 1. The age and / or gender of a predetermined user may be used to generate the tourist spot information.

[0022] In addition to the above functions, the server 2 of this embodiment also has a function of judging the validity of the travel data. The validity of the travel data is judged by a method of verifying the identity of the driver of the vehicle 1 with a specified user. The identity of the driver of the vehicle 1 with a specified user is verified based on biometric information included in the vehicle data. If the verification is successful, the server 2 judges that the travel data is valid. If the verification is unsuccessful, the server 2 judges that the travel data is valid. The server 2 uses the driving data determined to be valid to perform the above-mentioned analysis and provide the predetermined service. The driving data determined to be invalid may be discarded or used to provide a service other than the predetermined service.

[0023] The analysis of the travel data and the provision of the predetermined service may be performed by an external device other than the server 2. In this case, the server 2 may provide only the travel data that is determined to be valid among the travel data collected from the vehicle 1 to the external device.

[0024] (Vehicle system configuration) Here, the configuration of the vehicle system will be described with reference to Fig. 2. Fig. 2 is a block diagram showing an example of the configuration of each of the in-vehicle device 10 and the server 2 included in the vehicle system.

[0025] 2, the in-vehicle device 10 includes a sensor 100, an ECU 110, and a communication terminal 120. The ECU 110 and the communication terminal 120 communicate with each other based on standards such as CAN (Controller Area Network), LIN (Local Interconnect Network), or FlexRay. The vehicle-mounted device 10 is connected via an in-vehicle network. The configuration of the vehicle-mounted device 10 is not limited to the example shown in Fig. 2, and components can be changed, added, or omitted as appropriate depending on the embodiment.

[0026] The sensor 100 includes a plurality of sensors, such as a sensor for detecting the position of the vehicle 1 (e.g., a GPS receiver), a sensor for detecting the traveling speed of the vehicle 1 (e.g., a vehicle speed sensor), a sensor for detecting the traveling direction of the vehicle 1 (e.g., a gyro sensor), a sensor for detecting the behavior of the vehicle 1 (e.g., an acceleration sensor), a sensor for detecting the state of devices mounted on the vehicle 1 (e.g., an accelerator opening sensor, a brake pedal sensor, a steering sensor, a turn signal switch, etc.), and a camera mounted on the vehicle 1. Furthermore, the sensor 100 of this embodiment includes a sensor for acquiring biometric information of the driver. The sensor for acquiring biometric information of the driver includes at least one of a camera for capturing an image of the driver's face, a scanner for reading the driver's iris, a scanner for reading the shape of the driver's ear, a microphone for collecting the driver's voice, and a scanner for reading the driver's fingerprint.

[0027] The ECU 110 is a small computer that controls devices mounted on the vehicle 1 in response to a detection signal from the sensor 100. The ECU 110 includes a plurality of ECUs, such as an ECU for controlling a prime mover, an ECU for controlling a battery, an ECU for controlling a transmission, an ECU for controlling a brake, an ECU for controlling lighting devices (headlights, brake lights, blinker lights, etc.), an ECU for controlling a car navigation system, an ECU for controlling a multimedia device, an ECU for controlling an air conditioner, and an ECU for controlling a door lock device. The ECU 110 of this embodiment acquires running data and biometric information from the sensor 100 and the car navigation system, etc., and transmits the acquired running data and biometric information to the communication terminal 120. Such processing may be repeatedly executed at a predetermined period while the vehicle 1 is running (the ignition switch is on), or may be executed in response to a command from the communication terminal 120 that has received a request from the server 2.

[0028] The communication terminal 120 is a terminal that communicates with the server 2 through the network N1. The network N1 is, for example, a global public communication network such as the Internet, which is a WAN (Wide Area Network). The network N1 may be a telephone communication network such as a mobile phone and / or a Wi-Fi network. The communication terminal 120 may include a wireless communication network such as WiFi (registered trademark). The communication terminal 120 of this embodiment generates vehicle data using the driving data and biometric information received from the ECU 110. FIG. 3 is a diagram showing an example of the vehicle data in this embodiment. As exemplified in FIG. 3, the vehicle data in this embodiment includes a vehicle ID, biometric information of the driver, and driving data. The vehicle ID is an identifier for individually identifying the vehicle 1 included in the vehicle system. The vehicle ID may be the vehicle number of the vehicle 1, a character string marked on the vehicle registration plate, or a character string given when a specific user agrees to collection of vehicle data. The vehicle ID may be an identifier of the in-vehicle device 10 (e.g., a serial number, etc.). Such a vehicle ID is stored in a memory, etc., of the communication terminal 120.

[0029] Returning to the explanation of Fig. 2, the server 2 has a communication unit 210, a storage unit 220, and a control unit 230. Note that the configuration of the server 2 is not limited to the example shown in Fig. 2, and components can be changed, added, or omitted as appropriate depending on the embodiment.

[0030] The communication unit 210 is a communication interface for connecting the server 2 to the network N1. The communication unit 210 includes, for example, a network interface board and / or a wireless communication interface for wireless communication.

[0031] The storage unit 220 is configured to include a main storage device (e.g., RAM and ROM, etc.) and an auxiliary storage device (e.g., EPROM, HDD, and removable media, etc.). In addition to an OS (Operating System), the storage unit 220 of this embodiment stores programs executed by the processor of the server 2, data used when the programs are executed, etc. Furthermore, a vehicle management DB 221 is constructed in the storage unit 220 of this embodiment. The vehicle management DB 221 is constructed by the processor of the server 2 executing a DBMS (Database Management System) program.

[0032] Fig. 4 is a diagram showing an example of information stored in the vehicle management DB 221 in this embodiment. As exemplified in Fig. 4, the vehicle management DB 221 in this embodiment holds a plurality of records corresponding to each of a plurality of vehicles 1 included in the vehicle system. Each record has fields such as a vehicle ID, a user ID, and biometric information. Note that the configuration of the records held in the vehicle management DB 221 is not limited to the example shown in Fig. 4, and fields can be changed, added, or omitted as appropriate depending on the embodiment.

[0033] In the vehicle ID field, information (vehicle ID) for identifying each of the multiple vehicles 1 included in the vehicle system is registered. In the user ID field, an identifier (user ID) of a specific user corresponding to each vehicle 1 is registered. The user ID may be the name, nickname, email address, or telephone number of the specific user. As another example, the user ID may be a character string that is arbitrarily assigned when the specific user agrees to the collection of vehicle data. In the biometric information field, biometric information (e.g., at least one of face, iris, auricle, voiceprint, palm shape, fingerprint, etc.) of a specific user corresponding to each vehicle 1 is registered. Note that the type of biometric information registered in the biometric information field can be changed according to the type of biometric information that can be detected by the vehicle 1.

[0034] Returning to the description of FIG. 2, the control unit 230 of the server 2 is a software module that is realized by a processor such as a CPU or a GPU executing a program stored in the storage unit 220 (auxiliary storage device). The control unit 230 is triggered by the reception by the communication unit 210 of vehicle data transmitted from the in-vehicle device 10, and determines the validity of the driving data included in the vehicle data. In determining the validity of the driving data, first, the control unit 230 accesses the vehicle management DB 221 using the vehicle ID included in the vehicle data as an argument, and identifies a record in which information matching the vehicle ID is registered in the vehicle ID field. Next, the control unit 230 reads out the biometric information (biometric information of a specific user corresponding to the vehicle 1) registered in the biometric information field of the identified record. Then, the control unit 230 verifies the identity of the specific user and the driver of the vehicle 1 by comparing the biometric information of the specific user read out from the vehicle management DB 221 with the biometric information included in the vehicle data (biometric information of the driver of the vehicle 1). Matching the biometric information of the specific user with the biometric information of the driver of the vehicle 1 If the matching is successful (if the identity of the specified user and the driver of the vehicle 1 is successfully verified), the control unit 230 determines that the traveling data is valid. If the matching of the specified user's biometric information with the biometric information of the driver of the vehicle 1 fails (if the identity of the specified user and the driver of the vehicle 1 is failed), the control unit 230 determines that the traveling data is invalid.

[0035] If the driving data is determined to be valid, the control unit 230 analyzes the driving data and provides a predetermined service. If the driving data is determined to be invalid, the control unit 230 does not analyze the driving data or provide a predetermined service. In this case, the driving data determined to be invalid may be discarded or used to provide another service.

[0036] (Processing flow) A process flow executed by the server 2 in this embodiment will be described with reference to Fig. 5. Fig. 5 is a flowchart showing a process routine that is executed when the communication unit 210 of the server 2 receives vehicle data transmitted from the in-vehicle device 10. Note that the processor of the server 2 executes the process routine of Fig. 5, but here, the process routine will be described with the functional components of the server 2 acting as the execution subjects.

[0037] When the vehicle data transmitted from the in-vehicle device 10 is received by the communication unit 210 of the server 2, the control unit 230 acquires the vehicle data received by the communication unit 210 (step S101). After completing the process of step S101, the control unit 230 executes the process of step S102.

[0038] In step S102, the control unit 230 verifies the identity of the driver of the vehicle 1, which is the transmission source of the vehicle data, and the predetermined user corresponding to the vehicle 1. Specifically, the control unit 230 accesses the vehicle management DB 221 using the vehicle ID included in the vehicle data acquired in step S101 as an argument, and identifies a record in which information matching the vehicle ID is registered in the vehicle ID field. The control unit 230 reads out the biometric information (biometric information of the predetermined user) registered in the biometric information field of the identified record. The control unit 230 compares the biometric information of the predetermined user with the biometric information included in the vehicle data (biometric information of the driver of the vehicle 1). After completing the process of step S102, the control unit 230 executes the process of step S103.

[0039] In step S103, it is determined whether the verification of identity between the predetermined user and the driver has been successful. If the matching of the predetermined user's biometric information with the driver's biometric information is successful, the control unit 230 determines that the verification of identity between the predetermined user and the driver has been successful (positive determination in step S103). On the other hand, if the matching of the predetermined user's biometric information with the driver's biometric information is unsuccessful, the control unit 230 determines that the verification of identity between the predetermined user and the driver has been unsuccessful (negative determination in step S103).

[0040] If the determination in step S103 is affirmative, the control unit 230 executes the process of step S104. In step S104, the control unit 230 determines that the driving data included in the vehicle data acquired in step S101 is valid. On the other hand, if the determination in step S103 is negative, the control unit 230 executes the process of step S105. In step S105, the control unit 230 determines that the driving data included in the vehicle data acquired in step S101 is invalid.

[0041] When the control unit 230 has completed the process of step S104 or step S105, it ends the execution of this processing routine.

[0042] (Actions and Effects of the Embodiments) In the above-described embodiment, when the in-vehicle device 10 transmits the driving data collected during the driving of the vehicle 1 to the server 2, the in-vehicle device 10 also transmits the driver's biometric information to the server 2. In addition, in this embodiment, the storage unit 220 of the server 2 holds the biometric information of a specific user in a form associated with the vehicle 1. As a result, the control unit 230 of the server 2 can determine whether the driver of the vehicle 1 at the time the driving data was collected is a specific user based on the driver's biometric information and the biometric information of the specific user. As a result, for example, when a specific service is provided using driving data of the vehicle 1 driven by a user of the generation or sex to which the specific user belongs, it is possible to collect only driving data suitable for providing the specific service. Therefore, according to this embodiment, the accuracy of the driving data used to provide the specific service can be guaranteed.

[0043] In this embodiment, the server 2 corresponds to the "information processing device" according to the present disclosure. The control unit 230 of the server 2 corresponds to the "control unit" according to the present disclosure. Furthermore, the storage unit 220 of the server 2 corresponds to the "storage unit" according to the present disclosure.

[0044] <Modification> In the above-described embodiment, an example has been described in which biometric information of the driver of the vehicle 1 is used as the driver information. In contrast, information indicating the driving characteristics of the driver of the vehicle 1 may be used as the driver information. Examples of the information indicating the driving characteristics of the driver (hereinafter, sometimes referred to as "characteristic information") include the seat position of the driver's seat of the vehicle 1, the turn signal operation time (the time from when the turn signal switch is turned on to when the vehicle 1 completes changing course (the turn signal switch is automatically turned off)), the amount of change in the accelerator operation amount per unit time, the amount of change in the brake operation amount per unit time, or the time length from when the shift position is operated to reverse to when the vehicle 1 starts to reverse. Note that the characteristic information is not limited to the above-described examples, and may be any information indicating the driving characteristics (driving habits, etc.) of the driver.

[0045] When the above-mentioned characteristic information is used as the driver information, the in-vehicle device 10 may collect driving data and characteristic information while the vehicle 1 is driving, and generate vehicle data based on the collected driving data and characteristic information. In this case, the in-vehicle device 10 may generate vehicle data including a vehicle ID, characteristic information (corresponding to the "second information" according to the present disclosure) and driving data, instead of the vehicle data described with reference to FIG. 3. Furthermore, the vehicle management DB 221 of the server 2 may hold a record having a vehicle ID field, a user ID field and a characteristic information field, instead of the record described with reference to FIG. 4. The characteristic information registered in the characteristic information field at that time is characteristic information of a specific user (corresponding to the "first information" according to the present disclosure). Furthermore, the control unit 230 of the server 2 may verify the identity of the driver of the vehicle 1 and the specific user by comparing the characteristic information included in the driving data with the characteristic information held in the vehicle management DB 221.

[0046] According to the above-mentioned modified example, it is possible to obtain the same action and effect as the above-mentioned embodiment. Note that both biometric information and characteristic information may be used as the driver information. In this case, the control unit 230 of the server 2 may determine that the driving data is valid only when both the matching of the biometric information and the matching of the characteristic information are successful. This can further improve the accuracy of the driving data used to provide a specified service.

[0047] <Other embodiments> The above-described embodiment is merely an example, and the present disclosure may be modified as appropriate without departing from the spirit of the present disclosure. For example, part of the processing performed by the server 2 may be performed by the in-vehicle device 10. As an example, verification of the identity of the driver of the vehicle 1 and the specified user may be performed by the in-vehicle device 10. In that case, the in-vehicle device 10 will collect driving data and service the collected driving data only if the verification of the identity of the driver of the vehicle 1 and the specified user is successful. Alternatively, transmission to server 2 may be performed.

[0048] In addition, the processes and configurations described in this disclosure can be freely combined and implemented as long as no technical contradictions arise. Furthermore, a process described as being performed by one device may be shared and executed by multiple devices. Furthermore, a process described as being performed by different devices may be executed by one device. In a computer system, the hardware configuration for implementing each function can be flexibly changed. [Explanation of symbols]
