(First embodiment)
FIG. 1 is a diagram schematically illustrating the delivery management system 1. The delivery target P is delivered from the shipper to the destination via an area accumulation place, a large-scale accumulation place, a large-scale distribution place (large-scale accumulation place), and an area distribution place (area accumulation place). For example, a large-scale dump is a facility that is larger than an area dump. For example, a large-scale depot is a facility that is larger than an area distribution station. Some or all of the area accumulation center, the large-scale accumulation area, the large-scale distribution area, and the area distribution area can communicate with the distribution support apparatus 100 via the network NW. The network NW includes, for example, a local area network (LAN), a wide area network (WAN), and the Internet.

  FIG. 2 is a diagram illustrating a state where the delivery target P is received from the shipper. The delivery target P is, for example, a parcel. The delivery target P may be delivered to the attendant A in a state where an RFID (Radio Frequency IDentifier) tag TG1 is attached in advance, or the staff A may attach the RFID tag TG1. The RFID tag TG1 transmits a tag ID, which is identification information of the RFID tag TG1, by communication.

  The handy terminal HT transmits a bar code or a QR code (registered trademark) to a code reading unit, a character reading unit (OCR (Optical Character Recognition) unit) for reading characters, or sends an OCR request to an external device (for example, the distribution support device 100). A transmission unit, a tag communication unit that communicates with the RFID tag TG1, an input unit that receives a user's input operation, a network communication unit for connecting to a network NW via a cellular network or a Wi-Fi network, and the like are provided. Some of these functional configurations may be omitted from the handy terminal HT.

  The handy terminal HT distributes the tag ID, the transport information (shipper, delivery destination), the size of the delivery target P, and the characteristics (fragment, useless, temperature designation, etc.) via the network NW according to the operation of the attendant. It is transmitted to the support device 100. The size is represented by, for example, width, depth, and height, and is assumed to have been measured by some method. The information acquired by the handy terminal HT may be transmitted directly, or may be transmitted to the distribution support apparatus 100 via the network NW after data is downloaded to a terminal device (not shown). You may.

  FIG. 3 shows that the delivery object P is loaded in the box B by the camera CM1. The camera CM1 transmits the captured image to the distribution support apparatus 100 via the network NW, for example, together with the imaging time. Note that the clerk A shown in FIG. 2 and the clerk A shown in FIG. 3 may be the same person or different persons.

  A communicator TM1 that communicates with the RFID tag TG1 is attached to, for example, the wrist of the attendant A. The communicable range of the communication device TM1 is set such that the communication device TM1 can communicate with the RFID tag TG1 of the delivery target P while the delivery target P is held by the attendant A, for example. The communication device TM1 transmits a communication history including the tag ID of the RFID tag TG1 to the distribution support device 100 via the network NW. This communication history may be transmitted directly, or may be transmitted to the distribution support apparatus 100 via the network NW after data is downloaded from the communication device TM1 to a terminal device (not shown). . As a result, by referring to the order of the tag IDs appearing in the communication history, the distribution support apparatus 100 can detect the order in which the delivery targets P are stacked in the box B.

  Further, the order in which the delivery targets P are stacked in the boxes B may be obtained by a different method. For example, when the delivery target P is conveyed in a line by a belt conveyor, a communication device that communicates with the RFID tag may be provided on the conveyance path. The communicable range of the communication device is set such that the communication target can be communicated with the RFID tag TG1 of the delivery target P when the delivery target P is transported and passes near the communication device on the transport path. You. A communication device TM2 is provided near the area where the delivery target P is loaded in the box B. The communicable range of the communication device TM2 is set such that the communication device TM2 can communicate with the delivery management device 400 of the box B when the delivery target P is loaded on the box B. The communication device TM2 communicates with the delivery management device 400, and transmits a communication history including the identification information (box ID) of the box B registered in the delivery management device 400 to the distribution support device 100 via the network NW. . The communication device TM2 may acquire a part of the data including the loading status of the delivery target P to be written into the delivery management device 400 from the distribution support device 100 via the network NW and transmit the acquired data to the delivery management device 400. . Further, when the identification information of the box B is displayed in the box B, the camera CM1 captures the identification information of the box B. The camera CM1 transmits an image of the identification information of the box B to the physical distribution support apparatus 100 via the network NW together with the time at which the image was captured.

  When the delivery object P is automatically loaded on the box B, the loading pattern is known information. In this case, an automatic loading machine (not shown) transmits a loading pattern to the distribution support apparatus 100 via the network NW.

The truck TR may be a rental vehicle or the like, and the vehicle may not be specified by communication or the like. For this reason, the vehicle is specified by, for example, capturing an image of a license plate. As shown in the drawing, the camera CM2 is installed at a position where a license plate can be imaged, such as behind the truck TR. Note that a face image of the driver of the truck TR or the like may be captured together with or instead of the license plate. In this case, the camera CM2 captures a license plate or a driver's face image from the front of the truck TR. Further, a camera other than the camera CM2 may capture a license plate, a driver's face image, and the like from the front of the truck TR. The camera CM2 transmits the captured image to the distribution support device 100 together with, for example, the imaging time. The delivery management device 400 is attached to the box B, and the communication device TM3 detects the delivery management device 400 immediately before being loaded on the truck TR. Note that the delivery management device 400 may be placed in the box B. The communication device TM3 transmits the box ID of the delivery management device 400 to the distribution support device 100 together with the communication time, for example. The distribution support apparatus 100 can detect which box TR is loaded on which truck TR by using a combination of these technologies (for example, matching between the identification information of the communication device TM3 and the identification information of the camera CM2). . The communication device TM3 acquires part or all of the data including the loading status of the delivery target P to be written in the delivery management device 400 from the distribution support device 100 via the network NW, and transmits the data to the delivery management device 400.

The management information of the delivery target P corresponds to the delivery target data 122 shown in FIG. The group of information related to the delivery target P is treated as one record, and the record is associated with the delivery target P. For example, the above information is supplied from the distribution support device 100.

  For example, as the management information on the box B, the identification information of the box B, the identification information of the delivery target P loaded in the box B (delivery target identification information, and the like), and the position of the delivery target P in the box B ( ), Unloading pattern, transfer destination information (information indicating each collection point, etc.), transfer source information (information indicating each collection point, etc.), and box B mixedly loaded on truck TR. The identification information includes identification information (identification information of the box B group) indicating each box B at the time when the loading on the truck TR is completed, and identification information of the truck TR. The group of information related to the box B is treated as one record, and the record is associated with the box B. For example, the above information is supplied from the distribution support device 100.

  For example, the management information on the truck TR includes an identification number of the truck TR, information on an arrangement pattern of the boxes B on the carrier of the truck TR, position information of the truck TR (information of traveling points), current time information, and the like. The group of information related to the track TR is treated as one record, and the record is made to correspond to the track TR. For example, the above information is supplied from the distribution support device 100.

  Among the above-mentioned information, "box B group identification information" and "track TR identification information" in the management information about box B, "track TR identification number" and "track Each information of "information on arrangement pattern of box B on cargo bed of TR" is added when loading on truck TR is completed.

  In addition, among the above-mentioned information, the information of “position information of the track TR (information of the traveling point)” and “current time information” in the management information on the track TR are added periodically during transportation. You may.

The outline of the encryption processing and the decryption processing in the delivery management system 1 will be described with reference to FIG.
The transport facility 300 requests the distribution support apparatus 100 for an encryption key, and the encryption key is supplied from the distribution support apparatus 100. The transport facility 300 performs an encryption process using the encryption key supplied from the distribution support apparatus 100, and stores the encrypted data in the storage unit 410 of the delivery management apparatus 400.

  The delivery management device 400 is transported by the truck TR together with the box B from the transport source (the transport source facility 300 side) to the transport destination (the transport destination facility 500 side).

  The transfer destination facility 500 requests the distribution support device 100 for a decryption key, and the decryption key is supplied from the distribution support device 100. The destination facility 500 uses the decryption key supplied from the distribution support apparatus 100 to decrypt the data stored in the storage unit 410 of the delivery management apparatus 400. The transfer destination facility 500 determines the result of the decryption process, outputs a result of the determination, and displays the result of the determination on the terminal device 510 or the like.

  FIG. 13 is an explanatory diagram illustrating a functional configuration of the encryption processing and the decryption processing in the delivery management system 1.

(Preparation for encryption and decryption)
The transport facility 300 requests the distribution support apparatus 100 for an encryption key. Upon requesting the encryption key, the transport source facility 300 requests the distribution support apparatus 100 for the encryption key by adding information for specifying the transport destination. The distribution support apparatus 100 pays out the encryption key to the transport facility 300 in response to the request for the encryption key. For example, the dispensed encryption key is different for each application. As shown in the figure, a pair of keys K2 and K1 is issued to perform two encryption processes.

  The destination equipment 500 requests the distribution support apparatus 100 for a decryption key. In response to the request for the decryption key, the distribution support apparatus 100 specifies the request source (destination) and pays out the decryption key corresponding to the destination to the destination equipment 500. For example, the issued decryption key is different for each application. As shown in the figure, a pair of keys K1 and K2 are issued to perform two decryption processes. Thus, the destination facility 500 of the destination of the delivery target P has a key K1 (first encryption key (private key)) and a key K2 (second encryption key (public key)) corresponding to the key K1.

(Encryption processing)
In the transport facility 300, the encryption unit 425 performs two encryption processes.

  As a first encryption process, at least a part of data (original data) of the data (see FIG. 12) including the loading status of the delivery target P is encrypted using the key K2, and the encrypted data AUD1 (first data) is encrypted. Generated encrypted data). The encrypted data AUD1 (first encrypted data) is a cipher text of the original data.

  Prior to the second encryption processing, the encryption unit 425 generates summary data in which at least a part of the data including the loading status of the delivery target P is summarized by the encryption unit 325. For example, the summarizing unit 429 performs an operation based on a predetermined hash function and, based on the result of the operation, becomes a digest of at least a part of the data including the loading status of the delivery target P (original data). Generate signature data. Note that the above-described hash function is an example, and if the data including the loading status of the delivery target P is different, so long as the function results in a different result, other methods may be applied. Good.

  As a second encryption process, the encryption unit 425 encrypts the above-mentioned signature data using the key K2 to generate encrypted data AUD2 (second encrypted data). The encrypted data AUD2 (second encrypted data) becomes a signature of the original data.

  Note that the encryption unit 425 is included in the delivery management device 400. The key K2 may be stored in the delivery management device 400. However, in order to enhance security, the key K1 is stored in the storage unit 410 and the delivery management device 400 is transported together with the delivery target P or the like. Can not do it. The encryption unit 425 generates the encrypted data AUD2 (second encrypted data) which is treated as a signature of the encrypted data AUD1 (first encrypted data), and then generates the key K1 (first encrypted key (private key)). )) Is discarded and erased from the storage unit 410.

  After the above two encryption processes are completed, the above-described encrypted data AUD1 and AUD2 are written into the storage unit 410 of the delivery management device 400 by the writing unit 426. The delivery management device 400 in which the encrypted data AUD1 and the encrypted data AUD2 are written is transported to the transport destination by the truck TR together with the box B.

(Decryption processing)
After the box B is transported to the transport destination, the decryption unit 525 in the transport destination facility 500 performs at least two decryption processes. The two decryption processes decrypt the encrypted data of the encrypted data AUD1 (first encrypted data) and the encrypted data AUD2 (second encrypted data) using the decryption key.

  The decryption unit 525 decrypts the encrypted data AUD1 (first encrypted data) using a key K1 (corresponding to a first encryption key (secret key)) as a first decryption process. If the encrypted data AUD1 is legitimate, the above decryption reproduces the original data before being encrypted at the source. The decoding unit 525 generates summary data summarized by the summarizing unit 529 for the reproduced data. In the calculation in the summarizing section 529, the same calculation processing as in the above-described summarizing section 429 is performed.

  The decryption unit 525 decrypts the encrypted data AUD2 (second encrypted data) using the key K2 (corresponding to a second encryption key (public key)) as a second decryption process. If the encrypted data AUD2 is legitimate, the above-described decryption reproduces digest data (signature data) that is a digest of the original data before being encrypted at the carrier.

  The determining unit 527 collates the summary data obtained from the result of the first decryption processing with the summary data obtained from the result of the second decryption processing, and determines whether or not they are the same. If it is determined that they are the same, the box B is determined to have been transported from the transport source, and if it is determined that they are different, it is determined that the box B may not have been transported from the transport source . As described above, the validity of the encrypted data AUD1 (first encrypted data) is determined using the encrypted data AUD2 (second encrypted data) treated as the signature of the encrypted data AUD1 (first encrypted data). Verify the nature. In this way, the delivery management system 1 (the determination unit 527) can verify the validity of the first encrypted data using the signature sentence. The delivery management system 1 can determine whether or not the replacement of the box B has occurred, and can improve security. Further, since the delivery is not managed in units of P, the delivery can be managed efficiently.

  The determination unit 527 performs the above “encryption process” and “decryption process” for each box B transported by the truck TR, and determines each box B.

The delivery management device 400 according to the above-described embodiment has a storage unit 410 and is attached or placed on a box B (transportation aid) on which the delivery target P is loaded. The encryption unit 425 generates encrypted data based on the data including the loading status of the delivery target P in the box B. The writing unit 426 writes the encrypted data encrypted by the encryption unit 425 in the storage unit 410 of the delivery management device 400 at the source of the delivery target P. The reading unit 526 reads the encrypted data from the storage unit 410 of the delivery management device 400 at the destination of the delivery target P. The decryption unit 525 decrypts the encrypted data read by the read unit 526.
Thereby, the delivery management system 1 can efficiently manage delivery while maintaining security.

(First Modification of First Embodiment)
In the above embodiment, the determination method for each box B has been described as an example. However, a plurality of boxes B transported by the truck TR can be managed as a group (box B group) by the following method. In the case of this modified example, “identification information of the box B group” (see FIG. 12) is included in at least a part of the data (the original data) including the loading status of the delivery target P. The “box B group identification information” is written as identification information for specifying all the boxes B loaded together on the truck TR as a part of the information shown in FIG. 12 before the encryption process is performed. .

  The supplementary description of the acquisition unit 432 and the transmission processing unit 434 shown in FIG. The acquisition unit 432 acquires data received from another device or another box B, and causes the storage unit 410 to store the data. The transmission processing unit 434 transmits the data stored in the storage unit 410 of the own delivery management device 400 to the delivery management device of another box B via the communication unit 421 using a wireless signal. The delivery management device of the other box B corresponds to the delivery management device 400. The data transmitted by the transmission processing unit 434 via the communication unit 421 includes at least the identification information of the box B of the self-delivery management device 400.

  FIG. 14 is an explanatory diagram illustrating a process of managing a plurality of boxes B as a group. Each of FIGS. 7A to 7F shows a process in which a plurality of boxes are sequentially loaded on the carrier of the truck TR, and a method of determining the delivered object P to be delivered. A case where four boxes B are transported after the boxes B indicated by reference numerals B-1 to B-4 are stacked on the truck TR will be exemplified. As shown in FIG. 4 described above, the boxes B are sequentially loaded on the truck TR one by one.

  FIG. 14A shows a state where only the box B-1 is loaded. A solid line (thick line) square in the figure indicates a box B loaded, and a dotted square indicates a box B not loaded. In other words, the dotted rectangle indicates the loading waiting area. Note that the bold square indicates the box B loaded last. “B1” described inside the solid-line rectangle corresponding to “B-1” indicates the identification information “b1” of the own box B-1. For example, a bold square corresponding to “B-1” shown in the figure indicates that identification information of up to four boxes B constituting the box B group can be stored. In the same figure, the item of “identification information of the box B group” in the storage unit 410-1 of the delivery management device 400-1 of the box B-1 includes the identification information “b1” of the own box B-1 already loaded. Is held.

FIG. 2B shows a state where the boxes B-1 and B-2 are stacked. There is no change in the solid rectangle corresponding to “B-1” shown in the figure, and a thick rectangle corresponding to “B-2” is added. “B1” and “b2” described in a bold square corresponding to “B-2” indicate the identification information “b1” of the box B-1 and the identification information “b2” of the box B-2. In the figure, in the storage unit 410-2 of the delivery management device 400-2 of the box B-2, the item of "identification information of the box B group" contains the identification information "b1" of the already loaded box B-1. And the identification information “b2” of the own box B-2.
Here, illustration of the stage in which the box B-3 is stacked is omitted.

  FIG. 7C shows a state in which the box B-1, the box B-2, the box B-3, and the box B-4 are stacked. The data in the box B indicated by the solid squares corresponding to “B-1” and “B-2” shown in FIG. 11B has no change, and corresponds to the solid square corresponding to “B-3” and “B-4”. A thick line rectangle has been added. “B1”, “b2”, “b3”, and “b4” described in a bold square corresponding to “B-4” are identification information “b1” of the box B-1 and identification of the box B-2. The information “b2”, the identification information “b3” of the box B-3, and the identification information “b4” of the box B-4 are shown. The solid square corresponding to "B-3" is the same as above, and the description is omitted. In the figure, in the storage unit 410-4 of the delivery management device 400-4 of the box B-4, the item of "identification information of the box B group" contains the identification information "b1" of the already loaded box B-1. , The identification information “b2” of the box B-2, the identification information “b3” of the box B-3, and the identification information “b4” of the own box B-4.

  As described above, the boxes B are sequentially stacked. Accordingly, the number of pieces of identification information stored in the item of “identification information of box B group” in storage unit 410 included in delivery management device 400 of each box B differs. As the number of pieces of identification information stored in the item of “identification information of box B group” is larger, it is understood that the box B is loaded later. Alternatively, by comparing the write time of the last written data with reference to the storage unit 410 of each box, it is possible to specify the box B on which the write processing has been performed last.

  In the storage unit 410-4 of the delivery management device 400-4 of the last loaded box B, the identification information of all the boxes B loaded on the truck TR is written. Therefore, the delivery management device 400 specifies the storage unit 410 (delivery management device) in which the last writing was performed by communicating with each other. The transmission control unit 434 of the delivery management device 400 that has been specified as having been written last reads the identification information stored in the item of “identification information of the box B group” in the storage unit 410 of the own device. Then, the data is transmitted via the communication unit 421. Each of the transmitted identification information is received by another delivery management device 400, and is written in the item of “identification information of the box B group” in each storage unit 410 and copied.

FIG. 9D shows the result of the above-described copying. In this state, the data of the item of “box B group identification information” written in the storage unit 410 of each box B becomes common.
The process of sharing the data is performed at the stage at the transport source and before the encryption process is performed.

  FIG. 7E shows the encryption of each delivery management device 400 corresponding to the box B after the data of the item of “identification information of the box B group” becomes common as shown in FIG. 3 shows a state after the conversion process is performed. Shading inside the square corresponding to each box B indicates an encrypted state.

  As described above, the encryption processing including the item of “identification information of the box B group” is performed, and the information is retained as information at the time when each box B is loaded on the truck TR at each collection point. As a result, the information indicating the correspondence between the truck TR and the loaded boxes cannot be referred to until it is decrypted because the information is encrypted information. Therefore, even if the information indicating the correspondence between the truck TR and the loaded boxes is stored in the storage unit 410 of the delivery management device 400 and transported, since the information is encrypted, the destination of the transport destination is It cannot be referenced until the same information is decrypted at a repository or the like. The delivery management system 1 secures confidentiality when information is carried as described above.

  By the way, it is assumed that the box B-2 has been replaced during the transport from the transport source to the transport destination as shown in FIG. Even if a new box B-5 is loaded at the position of the box B-2, the information for the item of "identification information of the box B group" is not provided unless the procedure is carried out in a proper manner to load the truck TR. It is not written.

  Here, in the case where the replacement from the box B-2 to the box B-5 is disguised as a regular replacement, the feasibility of the disguise is examined. To disguise the replacement, it is necessary to make the data of the item of “identification information of box B group” regular. However, even if an attempt is made to fabricate the data of the item of “identification information of box B group”, the identification information of all the boxes B loaded on the same truck TR cannot be obtained. The data written in the storage unit 410 of each box B other than the box B-5 has already been encrypted, and even if it can be read, the read data must be decrypted. The key K1 for decrypting the encrypted data is not stored in the storage unit 410 of the delivery management device 400. As described above, it is not easy to disguise the replacement of the boxes B-2 to B-5 as a regular replacement.

  Further, both the sharing processing of the identification information and the encryption processing after the sharing processing, which are performed from (d) to (e), are performed on the data stored in the delivery management device 400-5 of the box B-5. Not yet. From such a viewpoint, it can be determined that the original is not transported properly. Since the delivery management device 400-5 in the box B-5 does not have a key (especially the key K1) for performing the encryption process, at least the encrypted signature can not be generated. .

  From this point of view, in the case of the delivery management device 400 of the present modification, even if a new box B-5 is replaced at the position of the box B-2 by an illegal process, the storage unit 410 of the delivery management device 400 Based on the information stored in each of the above, it can be easily detected that the exchange by the illegal processing has been performed. For example, the analysis unit 528 performs analysis on the state of the encrypted data and the data of the item of “identification information of the box B group” as an analysis target. Accordingly, the analysis unit 528 can easily detect that the exchange by the illegal processing has been performed.

  In the above, the illegal exchange in the box B unit has been described. However, even when the delivery target P is extracted from the specific box B or the delivery target P is exchanged from the specific box B, the impersonation is also performed. Considered as one form. In the case of forgery by the above method, at the stage of unloading after being delivered to the destination, the encrypted data (ciphertext) written in the storage unit 410 of the delivery management device 400 is decrypted to obtain the original. Data can be reproduced. By comparing the identification information of the delivery target P indicated by the reproduced original data with the data indicated by the RFID tag TG1 attached to the delivery target P, it is possible to determine the imitation of the delivery target P.

  The delivery management device 400 of the delivery management system 1 according to the first modification of the above-described embodiment includes a communication unit 421 that communicates with another delivery management device. 421 is used to communicate with other delivery management devices. The analysis unit 528 analyzes a transfer situation from the transfer source to the transfer destination based on a communication result between the delivery management devices.

  As described above, in the delivery management system 1 according to the first modified example of the above-described embodiment, the delivery management device 400 includes the communication unit 421 that communicates with another delivery management device. During the transportation, the communication unit 421 communicates with another delivery management device. The analysis unit 528 analyzes a transfer situation from the transfer source to the transfer destination based on a communication result between the delivery management devices.

  With such a delivery management system 1, delivery management can be performed efficiently while maintaining security.

(Second Modification of First Embodiment)
In the above embodiment, the encryption data is generated at the transport source. However, the encryption data may be further generated while being transported by the truck TR.

  For example, using the timer function of the timer unit 437, information is periodically shared between the delivery management devices 400 during the transportation. The result of information sharing periodically during transport is encrypted and stored in the storage unit 410 as time-series data. In this case, there is no need to generate a signature sentence generated at the carrier. In the second modified example, it is preferable that the encryption unit 425 performs an encryption process in which a result of periodically sharing information during transport is a message using the key K2 stored in the storage unit 410. . The information that is periodically shared during transport includes information that is shared between boxes transported together by the truck TR. Note that the key K2 of this modification is generated by a public key method.

  By performing the above-described processing, an abnormal event that has occurred during transportation can be recorded. The data left in the record is also encrypted, so that the reliability of the information left in the record can be ensured until the post-analysis processing is performed.

(Second embodiment)
FIG. 9 described above is a schematic configuration diagram of the delivery management system 1A.
In the following description, for example, the delivery of the delivery target P between the “large-scale dump” and the “area distribution station (area dump)” shown in FIG. 1 is performed in the same manner as in the first embodiment. A description will be given of an example in which the method is implemented. In the case of an area distribution center (area accumulation center), the number of bases increases, and it may be desired to simplify the equipment to be deployed. The configuration shown in the present embodiment is particularly suitable for a case where the transport destination is an area distribution center (area accumulation place).

A software function unit that functions when the management program 124 is executed. The decoding unit 170, the determination unit 180, and the analysis unit 190 correspond to the decoding unit 525, the determination unit 527, and the analysis unit 528 in the reading device 520 illustrated in FIG. Perform processing.

  The encryption key management unit 160A associates information specifying a predetermined encryption processing method and data including an encryption key and a decryption key used in the encryption processing with identification information indicating a transport destination. Stored as encryption key data 126. The encryption key management unit 160A returns the encryption key data 126 according to the received request. The encryption key data 126 corresponding to the request includes information designating an encryption processing method corresponding to a transport destination or a request source of the transport of the delivery target according to the request, and an encryption key used for the encryption processing.

  As shown in FIG. 9 described above, the delivery management system 1A includes a logistics support device 100A, a transport source facility 300, and a transport destination facility 500A. The logistics support device 100A and the transfer destination equipment 500A correspond to the logistics support device 100 and the transfer destination equipment 500.

  The transfer destination facility 500A includes a terminal device 510A and a reading device 520A.

The reading device 520A includes a communication unit 521, an output unit 522, a storage unit 524, and a reading unit 526. The reading device 520A (reading unit 526) reads data stored in the storage unit of the delivery management device 400 from the delivery management device 400 provided in the box B on which the delivery target P is loaded and transported. The reading device 520A transmits encrypted data such as “data related to the data including the loading status of the delivery target P” to the distribution support device 100A via the communication unit 521.

The logistics support device 100A receives the encrypted data transmitted from the transport destination facility 500A, and performs a decryption process by the decryption unit 170. The determination unit 180 makes a determination based on the result of the decoding process. The analysis unit 190 performs the same analysis processing as the analysis unit 528.
The terminal device 510A refers to the determination result by the determination unit 180 or the analysis result of the analysis unit 190 and displays the result.

  As described above, the transport destination equipment 500A of the delivery management system 1A of the present embodiment can obtain a determination result or an analysis result without receiving a decryption key for decryption processing from the distribution support device 100A.

(Third embodiment)
FIG. 17 is a schematic configuration diagram of the delivery management system 1B.
In the following description, similar to the first embodiment, for example, the case where the delivery of the delivery target P between the “large-scale accumulation center” and the “large-scale distribution station” illustrated in FIG. 1 is performed. This will be described using an example. If the encryption processing is made more complicated, the time for the encryption processing and the decryption processing may become longer. In particular, in the case of a large-scale accumulation center and a large-scale distribution station, the number of delivery target units handled and the number of boxes B may be large. In the present embodiment, a configuration for shortening the time of the encryption processing at the large-scale accumulation center will be exemplified. The main difference of the present embodiment from the first embodiment is that a part of the encryption processing for generating the encrypted data is performed by the transport facility 300B.

  The delivery management system 1B includes a logistics support device 100, a transfer source device 300B, a delivery management device 400B, and a transfer destination device 500. The logistics support device 100, the transfer source equipment 300B, and the transfer destination equipment 500 are communicably connected via a network NW. The transfer source equipment 300B corresponds to the transfer source equipment 300 in FIG. 9 described above.

  The transport facility 300B includes a loading machine 310, a writing device 320, a communication device TM2, and a communication device TM3. The writing device 320 encrypts the data acquired from the distribution support device 100 and writes the data to the delivery management device 400.

Note that the encryption unit 325 performs the encryption process in the case where the delivery management device 400 is provided in the transport source facility 300B, that is, the encryption process up to the state of being transported, instead of the above-described encryption unit 425. The writing unit 326 writes the data encrypted by the encryption unit 325 to the storage unit 410.

FIG. 19 is a functional configuration diagram illustrating one mode of the delivery management device 400B.
The delivery management device 400B includes a storage unit 410, an acquisition unit 432, a transmission processing unit 434, an encryption unit 435, a writing unit 436, and a clock unit 437.

  The encryption unit 435 and the writing unit 436 correspond to the encryption unit 425 and the writing unit 426 of the delivery management device 400 shown in FIG. Note that the encryption unit 435 performs the encryption process after being conveyed, instead of the encryption unit 425 described above.
