  The encryption unit 27 encrypts a vehicle ID (vehicle identifier) that identifies the vehicle 200 on which the vehicle-mounted device 24 is mounted, and generates encryption information.

  The communication unit 28 has a function as an in-vehicle transmission unit. Under the control of the in-vehicle control unit 25, image data and encryption obtained by imaging the surrounding vehicle 300 existing around the vehicle 200 with the camera unit 21. The encryption information generated by the unit 27 is transmitted to the server 100. That is, the vehicle-mounted device 24 transmits image data of the surrounding vehicle 300 captured by the camera unit 21 together with the encryption information to the server 100 when the vehicle 200 contacts or collides with the surrounding vehicle 300 existing in the vicinity.

  FIG. 3 is a block diagram illustrating an example of a configuration of the server 100 as the image distribution apparatus according to the present embodiment. The server 100 includes a control unit 11, a communication unit 12, a decoding unit 13, a determination unit 14, a license plate specifying unit 15, a distribution unit 16, a storage unit 17, and the like that control the entire server.

  The communication unit 12 has a function as a device reception unit, and receives image data and encryption information transmitted by the vehicle-mounted device 24.

  The decryption unit 13 decrypts the vehicle ID from the encryption information received by the communication unit 12.

  The storage unit 17 stores a vehicle ID of a vehicle owned by a user registered in advance. Details will be described later.

  The determination unit 14 determines whether the vehicle ID decoded by the decoding unit 13 matches a vehicle ID registered in advance.

  The license plate specifying unit 15 has a function as a specifying unit, and specifies the license plate information of the surrounding vehicle 300 from the received image data when the determination unit 14 determines that the vehicle IDs match. As a method for specifying the license plate based on the image data, a known appropriate technique can be used. As described above, the license plate information includes a land transportation branch office, a classification number, and a serial number. The license plate specifying unit 15 may specify all of the license plate information, or may specify a part of the license plate information if it cannot be specified.

  The storage unit 17 stores distribution destination information for distributing the image data received by the communication unit 12. FIG. 4 is an explanatory diagram showing an example of a delivery destination related to the user of the vehicle (own vehicle) 200. As for the user of the vehicle (own vehicle) 200, as shown in FIG. 4, a delivery destination is stored in association with a vehicle ID, license plate information, an identification number (also referred to as a key ID), and the like. The delivery destination is, for example, an e-mail address of the user's family, friend, acquaintance, or company. The association with the delivery destination may not be all of the vehicle ID, the license plate information, and the identification number. For example, only the license plate information, only the vehicle ID, the combination of the license plate information and the vehicle ID, only the identification number A combination of an identification number and a vehicle ID can be set as appropriate.

  FIG. 5 is an explanatory diagram illustrating an example of a delivery destination related to the user of the surrounding vehicle 300. As for the user of the surrounding vehicle 300, as shown in FIG. 5, the delivery destination is stored in association with the license plate information. The delivery destination is, for example, an e-mail address of the user's family, friend, acquaintance, or company. This is because, unlike the vehicle (own vehicle) 200, in the case of the surrounding vehicle 300, the license plate information can be specified from the captured image data, but the vehicle ID and the identification number cannot be specified.

  The distribution unit 16 refers to the storage unit 17 to distribute the image data to the distribution destination corresponding to the license plate information specified by the license plate specifying unit 15. A delivery destination is a family (a driver, a passenger, etc.), a friend, an acquaintance, or a company of a user who uses the surrounding vehicle 300.

  As described above, the vehicle-mounted device 24 transmits, to the server 100, encryption information obtained by encrypting the vehicle ID together with image data obtained by imaging. Since the server 100 authenticates the decrypted vehicle ID (determines matching or mismatching), it is possible to prevent a third party who is not a party from impersonating and illegally using image data, thereby improving security. . In addition, a delivery destination (for example, a partner's family, friend, etc.) that associates image data obtained by imaging the surrounding vehicle 300 (in the case of a traffic accident, a vehicle on the other side of the own vehicle) based on the license plate information of the surrounding vehicle 300. ) Automatically, it is possible to promptly notify the occurrence of a traffic accident.

  The encryption unit 27 may generate the encryption information by encrypting the license plate information of the vehicle 200. That is, the encryption information transmitted by the communication unit 28 is generated by encrypting both the vehicle ID and the license plate information.

  In this case, the decryption unit 13 of the server 100 decrypts the encryption information. The determination unit 14 determines whether the license plate information decrypted by the decryption unit 13 matches the license plate information registered in advance. That is, the determination unit 14 performs two-step authentication using both the vehicle ID and the license plate information.

  When the determination unit 14 determines that the license plate information matches, the license plate specifying unit 15 specifies the license plate information of the surrounding vehicle 300 from the received image data. By performing two-step authentication using both vehicle ID and license plate information, security can be further enhanced.

  Further, the encryption unit 27 may encrypt the identification number (portable device identifier, key ID) to generate encryption information. That is, the encryption information transmitted by the communication unit 28 is generated by encrypting both the vehicle ID and the identification number, or is generated by encrypting the vehicle ID, the license plate information, and the identification number.

  In this case, the determination unit 14 of the server 100 determines whether or not the identification number decoded by the decoding unit 13 matches an identification number registered in advance. That is, the determination unit 14 performs two-step authentication using both the vehicle ID and the identification number. Or the determination part 14 performs three-step authentication using vehicle ID, license plate information, and an identification number.

  When the determination unit 14 determines that the identification numbers match, the license plate specifying unit 15 specifies the number plate information of the surrounding vehicle 300 from the received image data. By performing two-step authentication using both the vehicle ID and the identification number, security can be further enhanced. Moreover, security can be further improved by performing three-step authentication using vehicle ID, license plate information, and an identification number.

  The distribution unit 16 may distribute the image data to a distribution destination corresponding to the vehicle ID of the vehicle (own vehicle) 200 or the license plate information of the vehicle (own vehicle) 200. As a result, image data is automatically distributed to the distribution destinations such as family, friends, acquaintances or companies of the user (driver, passenger, etc.) of the vehicle (own vehicle) 200, so that the occurrence of a traffic accident is quickly notified. can do.

  In addition, when the license plate identification unit 15 cannot identify the license plate information under the control of the control unit 11, the communication unit 12 transmits request information for requesting image data to the vehicle-mounted device 24.

  In this case, the communication unit 28 of the vehicle-mounted device 24 receives the request information transmitted by the server 100. And the vehicle-mounted control part 25 controls the camera part 21, and images the surrounding vehicle 300 again, when request information is received. The communication unit 28 transmits the image data obtained by imaging again to the server 100 together with the encryption information. The server 100 can specify the license plate information again using the received image data. As a result, even if the license plate of the surrounding vehicle 300 is not clearly shown in the image data once captured, the license plate information of the surrounding vehicle 300 can be reliably specified by imaging again.

  FIG. 6 is a flowchart showing an example of the processing procedure of the vehicle-mounted device 24 of the present embodiment. The vehicle-mounted control unit 25 determines whether or not a collision has been detected (S11). If no collision has been detected (NO in S11), the process in step S11 is repeated. When a collision is detected (YES in S11), the vehicle-mounted control unit 25 images the surrounding vehicle 300 (S12).

  The in-vehicle control unit 25 encrypts the vehicle ID and license plate information of the vehicle 200 to generate encryption information (S13), and transmits the generated encryption information and image data obtained by imaging to the server 100 (S14). .

  The in-vehicle control unit 25 determines whether or not re-imaging request information has been received (S15). When the request signal is received (YES in S15), the in-vehicle control unit 25 performs processing from step S12. If the request signal has not been received (NO in S15), the in-vehicle control unit 25 ends the process.

  In the above-described processing, only the vehicle ID may be used for encryption, or only the license plate information may be used.

  FIG. 7 is a flowchart illustrating an example of a processing procedure of the server 100 according to the present embodiment. The control unit 11 receives the image data and the encryption information (S31), and decrypts the received encryption information (S32). The control unit 11 determines whether or not the vehicle ID obtained by decryption matches the vehicle ID registered in advance (S33).

  When the vehicle IDs match (YES in S33), the control unit 11 determines whether or not the license plate information obtained by decoding matches the license plate information registered in advance (S34).

  When the license plate information matches (YES in S34), the control unit 11 determines whether or not the license plate information of the surrounding vehicle 300 can be specified from the received image data (S35) and can specify the license plate information. If it is possible (YES in S35), the image data is transmitted to the distribution destination corresponding to the specified license plate information (S36), and the process is terminated.

  When the license plate information cannot be specified (NO in S35), the control unit 11 transmits re-imaging request information to the vehicle 200 (on-vehicle device 24) (S37), and performs the processing after step S31. .

  On the other hand, if the vehicle IDs do not match (NO in S33), or if the license plate information does not match (NO in S34), the control unit 11 determines that there is fraud such as impersonation and performs the process of step S36. The process is finished without.

  In addition, in the above-mentioned process, you may make it process the process of step S33, S34 only according to the encryption information which the onboard equipment 24 transmits.

  The image distribution apparatus according to the present embodiment can also be realized using a general-purpose computer including a CPU, a RAM, and the like. That is, by reading a recording medium recording a computer program that defines each processing procedure as shown in FIG. 7 with a recording medium reader provided in the computer, the computer program is loaded into the RAM, and the computer program is loaded into the CPU. By executing the above, an image distribution apparatus can be realized on a computer.

  In the above-described embodiment, the configuration is such that encryption information is generated by encrypting any one or any combination of the vehicle ID, the license plate information, and the identification number. However, the present invention is not limited to this. Random numbers may be used when doing so. As a result, a different random number is dynamically used every time encryption is performed, so that security can be further improved.

  In the above-described embodiment, when a collision is detected, the image data and the encryption information are automatically transmitted. However, the present invention is not limited to this, and an operation switch provided on the vehicle-mounted device 24 is operated. Thus, the transmission start may be controlled manually. In this case, for example, an image obtained by imaging can be displayed on a display screen provided in the vehicle-mounted device 24 and transmitted after the user confirms the image. Moreover, you may make it transmit image data using a mobile telephone, a notebook personal computer, a tablet terminal, a smart phone.

  In the above-described embodiment, the image data is transmitted to the delivery destination related to the user of the vehicle (own vehicle) 200 and the surrounding vehicle 300, but is not limited thereto. For example, image data obtained by imaging may be transmitted to the nearest police station or fire department. As a result, the relevant organization is notified promptly after the accident occurs, so if there is an accident party who has escaped, emergency arrangement of the fugitive can be made promptly based on the location information of the vehicle 200. If there is an injured person, it can be quickly transported to a medical institution.

  The disclosed embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
