  By the way, in the information-oriented society in recent years, management of personal information is regarded as important, and it is desired to protect the personal information of senders and receivers even in the delivery of goods. However, conventionally, a method of delivering a slip with the name and address of the sender or receiver attached to an article is generally delivered. In such a delivery method, personal information is transferred to a third party during the delivery. It was easy to obtain and was not perfect in terms of personal information protection. In addition, the attached slip is often thrown away, and there is a concern that personal information may leak from the used slip.

  In addition, there are many cases where one or a plurality of relay bases (bases for delivery to the next base, not bases that deliver directly to the receiver) are involved in the delivery of goods. Since the goods are not directly handed over to the receiver, it is only necessary to have information that can specify the next base. That is, the personal information of the receiver and sender is basically unnecessary at the relay site, and it is desirable that personal information cannot be acquired even at the relay site in order to protect personal information more strictly. .

1. Overall Configuration First, the overall configuration of the delivery management system 1 will be described below.
The delivery management system 1 according to the present embodiment includes a reading device 10 provided at a delivery base that delivers an article to a recipient, a reading device 110 provided at a relay base, and a management server 2 provided at the management base. These are configured to be connected via a telecommunication line N such as the Internet.
The “QR code” in this specification is in accordance with the Japanese Industrial Standard (JIS) two-dimensional code symbol-QR code-basic specification (JIS X 0510: 2004). Also, the “relay base” is a base that is interposed between the sender and the delivery base and delivers the article to the next base. In the example of FIG. 1, an agency, a collection / delivery base, and a regional delivery base correspond to a “relay base”.

  A management server 2 (a management server 2 corresponds to an example of a “delivery management device”) distributed to a management site is an information processing device configured by a known personal computer or the like, as shown in FIG. A CPU 6, a ROM 4, a RAM 5, a monitor 6 including a liquid crystal display device, a hard disk drive 7, an operation unit 8 including a keyboard and a mouse are provided. Further, an interface 9 connected to a telecommunication line N such as the Internet is provided, and the reader 9 and the reader 110 are connected via the interface 9.

  As shown in FIG. 1, the reading device 10 arranged at the delivery base is configured by a QR code reader 20 and an information processing device 11 including a known personal computer. As shown in FIG. 2, the information processing apparatus 11 includes a CPU 13, a ROM 14, a RAM 15, a monitor 16 including a liquid crystal display device, a hard disk drive 17, an operation unit 18 including a keyboard and a mouse. In addition, an interface 12 connected to a telecommunication line N such as the Internet is provided, and communication with the management server 2 is possible via this interface 12.

  As shown in FIG. 3, the QR code reader 20 mainly includes an optical system such as an illumination light source 21, a light receiving sensor 23, and an imaging lens 27, a memory 35, a control circuit 40, an operation switch 42, a liquid crystal display 46, and the like. And a power supply system such as a power switch 41 and a battery 49. These are mounted on a printed wiring board (not shown) or housed in a housing (not shown), and are configured in the same manner as a QR code reader of general specifications in hardware.

The optical system includes an illumination light source 21, a light receiving sensor 23, an imaging lens 27, and the like. The illumination light source 21 functions as an illumination light source capable of emitting illumination light Lf, and includes, for example, a red LED and a diffusion lens, a condensing lens, and the like provided on the emission side of the LED. In the present embodiment , illumination light sources 21 are provided on both sides of the light receiving sensor 23, and the illumination light Lf can be irradiated toward the QR code Q through a reading port of a case (not shown). A configuration example of the QR code Q will be described later.

  The light receiving sensor 23 is configured to receive the reflected light Lr irradiated and reflected on the QR code Q. For example, the light receiving sensor 23 is an area in which light receiving elements that are solid-state imaging elements such as C-MOS and CCD are two-dimensionally arranged. A sensor corresponds to this. The light receiving sensor 23 is mounted on a printed wiring board (not shown) so that incident light incident through the imaging lens 27 can be received by the light receiving surface 23a.

  The imaging lens 27 functions as an imaging optical system capable of condensing incident light incident from the outside via a reading port and forming an image on the light receiving surface 23a of the light receiving sensor 23. And a plurality of condensing lenses housed in the lens barrel.

  Next, a configuration outline of the microcomputer system will be described. The microcomputer system includes an amplification circuit 31, an A / D conversion circuit 33, a memory 35, an address generation circuit 36, a synchronization signal generation circuit 38, a control circuit 40, an operation switch 42, an LED 43, a buzzer 44, a liquid crystal display 46, and a communication interface 48. Etc. As the name suggests, this microcomputer system is configured around a control circuit 40 and a memory 35 that can function as a microcomputer.

  The image signal output from the light receiving sensor 23 of the optical system is input to the amplifier circuit 31, amplified by a predetermined gain, and then input to the A / D conversion circuit 33, so that it is converted from an analog signal to a digital signal. . When the digitized image signal, that is, image data is input to the memory 35, it is stored in the image data storage area. The synchronization signal generation circuit 38 is configured to generate a synchronization signal for the light receiving sensor 23 and the address generation circuit 36. The address generation circuit 36 is based on the synchronization signal supplied from the synchronization signal generation circuit 38. Thus, the storage address of the image data stored in the memory 35 can be generated.

  The memory 35 is a semiconductor memory device, and corresponds to, for example, a RAM (DRAM, SRAM, etc.) or a ROM (EPROM, EEPROM, etc.). In addition to the above-described image data storage area, the RAM of the memory 35 is configured so as to be able to secure a work area used by the control circuit 40 during each processing such as arithmetic operation and logical operation. The ROM stores in advance a predetermined program that can execute a reading process and the like that will be described later, and a system program that can control each piece of hardware such as the illumination light source 21 and the light receiving sensor 23.

The control circuit 40 is a microcomputer that can control the entire QR code reader 20 and includes a CPU, a system bus, an input / output interface, and the like. The control circuit 40 can constitute an information processing apparatus together with the memory 35 and has an information processing function. The control circuit 40 is configured to be connectable to various input / output devices via a built-in input / output interface. In the case of the first embodiment , the power switch 41, the operation switch 42, the LED 43, and the buzzer 44 are configured. A liquid crystal display 46, a communication interface 48, and the like are connected.

  Thereby, for example, monitoring and management of the power switch 41 and the operation switch 42, turning on / off the LED 43 functioning as an indicator, turning on / off the buzzer 44 capable of generating a beep sound and an alarm sound, and further reading the QR code Screen control of the liquid crystal display 46 capable of displaying the code content by Q, communication control of the communication interface 48 enabling serial communication with an external device, and the like are enabled. Note that the information processing apparatus 11 is connected to the communication interface 48 as a host system of the QR code reader 20.

  The power supply system includes a power switch 41, a battery 49, and the like. When the power switch 41 managed by the control circuit 40 is turned on and off, the conduction of the drive voltage supplied from the battery 49 to each of the above-described devices and circuits is performed. Or shut off is controlled. The battery 49 is a secondary battery capable of generating a predetermined DC voltage, and corresponds to, for example, a lithium ion battery. Further, for example, a configuration may be adopted in which power is supplied from an external device such as the information processing apparatus 11 connected via the communication interface 48 without using the battery 49. In this case, the battery 49 is unnecessary. .

  By configuring the QR code reader 20 in this way, for example, when the power switch 41 is turned on and a predetermined self-diagnosis process or the like is normally completed and the QR code Q can be read, the illumination light Lf is emitted. The input of the operation switch 42 (for example, a trigger switch) is given. Accordingly, when the user pulls the trigger switch to turn it on, the control circuit 40 outputs a light emission signal to the illumination light source 21 based on the synchronization signal, and the illumination light source 21 that has received the light emission signal turns on the LED. Light is emitted to irradiate illumination light Lf.

  Then, the illumination light Lf irradiated to the QR code Q is reflected, and the reflected light Lr enters the imaging lens 27 through the reading port, so that the image of the QR code Q is formed on the light receiving surface 23a of the light receiving sensor 23. Is imaged. Thereby, since the image of the QR code Q exposes the light receiving sensor 23, the image data of the QR code Q processed by the microcomputer system described above is read through the image data storage area of the memory 35 (FIG. 10, FIG. 11). The reading process will be described later.

  The reading device 110 arranged at a relay base (agency store, collection / delivery base, regional delivery base) includes a QR code reader 120 that reads a QR code Q and an information processing device 111 that includes a known personal computer or the like. As shown in FIG. 2, the information processing apparatus 111 includes a CPU 113, a ROM 114, a RAM 115, a monitor 116 including a liquid crystal display device, a hard disk drive 117, an operation unit 118 including a keyboard and a mouse, and the like. In addition, an interface 112 connected to an electric communication line N such as the Internet is provided, and communication with the management server 2 is possible via this interface 112. The QR code reader 120 has the same configuration as the QR code reader 20 in terms of hardware (the configuration shown in FIG. 3), and the built-in software configuration is different from that of the QR code reader 20.

  In addition, a known printer 130 is connected to the information processing apparatus 111 provided in the agency, and the QR code Q is printed on the slip by the printer 130 in response to a command from the information processing apparatus 111. ing. The printing of the QR code Q will be described later.

The delivery management system 1 configured as described above functions as a system that manages delivery of articles from a sender to a receiver. The outline is as follows.
First, the delivery management system 1 does not include the delivery information to be attached to the article at the time of delivery, the first delivery information including at least the subject information for specifying the receiver, and the specifying information for specifying the sender and the receiver, and the article. And the second delivery information including the order information of the bases to which the goods are delivered. Then, the delivery information is encoded in a state where the first delivery information is encrypted, and an information code (QR code Q to be described later) to be attached to the article is generated.

  Furthermore, in the reader 10 provided at the delivery base (the reader 10 corresponds to an example of “first information reader”), the encrypted first delivery information is decrypted based on a decryption algorithm; Has been. As a result, the encrypted first delivery information can be read at the delivery base, and the main information that can identify the recipient can be grasped at the delivery base.

Further, the reading device 110 provided at the relay base (the reading device 110 corresponds to an example of the second information reading device) is configured to specify the second delivery information (that is, the sender and the receiver) of the information code (QR code Q). Information that does not include the specific information to be specified and includes the order information of the site to which the article is delivered) and can display the order information. That is, in the delivery management system 1 according to the present embodiment , the display of the content of the subject information at each relay base is prohibited by the encryption of the first delivery information, and the content information of the subject information can be displayed only at the delivery base. -ing

2. Processing at Request Next, specific processing performed in the delivery management system 1 according to the present embodiment will be described. First, processing at the time of request (hereinafter also referred to as processing at request) for receiving a request from a sender and generating an information code (QR code Q) will be described with reference to FIG.

  The request processing is processing performed based on a program provided in the management server 2 and is started when the sender accesses the management server 2 via the telecommunication line N. Note that the sender may access the management server 2 through a personal computer provided at home or the like, or from the information processing device 111 provided at an agency (for example, an agency near the home). Good. In the following description, a case where the sender accesses the management server 2 from the agency will be described as an example.

When the request process is started, first, a process of displaying an input screen for inputting request information on the monitor of the information processing apparatus that has accessed (that is, the monitor of the agency store) is performed (S1). Specifically, for example, screen information constituting an input form as shown in FIG. 6 is given from the management server 2 to the information processing apparatus 111 of the agency. This screen information constitutes the input form displayed on the browser, for example, and the sender uses this input form to enter his / her name, address, phone number, recipient's name, address, phone number, etc. Is input as request information to the management server 2 via the telecommunication line N. In the present embodiment , in a slip to be attached to an article, a message can be recorded separately from the information code (QR code Q), and when the sender inputs a message using the input form of FIG. This message is sent to the management server 2. In the example of FIG. 6, a message such as a desired sentence can be input in the display item column, and information input in this column is sent to the management server 2 as a message.

  If it is determined in S2 that the input of request information has been completed, the process proceeds to Yes, and the input request information is acquired by the management server 2 and stored in storage means such as the RAM 5 (S3). Further, a process for determining a delivery route based on the input request information is performed (S4). Specifically, the delivery route is determined based on the address of the sender and the address of the receiver included in the request information, or based on the address of the store where the sender brought in the goods and the address of the receiver. Various methods for determining the delivery route are conceivable. For example, the delivery route can be determined as follows.

  First, in the management server 2, location information of bases that should be candidates for the agency, collection / delivery base, regional delivery base, and delivery base is prepared as a database. There are various examples of the arrangement of relay bases and delivery bases. However, in the following explanation, there are a plurality of sales offices and a plurality of delivery bases for each municipality, with one ratio for each municipality or multiple municipalities. A case will be described as a representative example in which a collection / delivery base is provided and, further, one regional delivery base is provided for each prefecture or a plurality of prefectures. In addition, the same base may serve as both an agency and a delivery base.

  When the address of the sender is specified by the request information, the agency store closest to the address is selected from the database (in the case where the sender brings the article to the agency store, the agency store is selected). Further, the collection / delivery base closest to the selected agency (the sender-side collection / delivery base) is identified, and the regional delivery base (the sender-side regional delivery base) closest to the identified collection / delivery base is identified. In this way, it is possible to determine the route from the sender (or the agency where the sender brought in the article) to the regional delivery base on the sender side.

  Note that the method of determining the collection / delivery base and the regional delivery base for each request as described above may not be used. For example, for each agency, a collection / delivery base (collector / delivery base on the sender side) and a regional delivery base ( (Regional delivery base on the sender side) may be registered and stored in a database. In this case, after selecting the agent store closest to the sender's address (or after selecting the agent store where the sender brought in the goods), the sender side collection and delivery base and the sender side registered as the base corresponding to the agent store You can choose a regional delivery base.

  Similarly, the route from the recipient to the regional delivery base on the recipient side can also be determined. For example, when the address of the recipient is specified by the request information, the delivery base closest to the address is selected from the database. Further, a collection / delivery base closest to the selected delivery base (collection / delivery base on the receiver side) is specified, and a regional delivery base (collection / delivery base on the receiver side) closest to the specified collection / delivery base is specified. In this way, the route from the regional delivery base on the receiver side to the delivery base can be determined. In addition, the method of determining the collection / delivery base and the regional delivery base for each request as described above may not be used. For example, for each delivery base, a collection / delivery base (collection / delivery base on the receiver side) and a regional delivery base are provided as corresponding bases. (Regional delivery base on the receiver side) may be registered and stored in a database. In this case, after selecting the delivery base closest to the address of the recipient, the receiver-side collection and delivery base and the receiver-side regional delivery base registered as the base corresponding to the delivery base may be selected.

After the delivery route is determined in S4, order information is generated (S5). The order information indicates the order of the bases on the determined route, and can be generated as information in which the base codes are arranged in order, for example. In this embodiment , a code is associated with each site and stored in a database, and when a delivery route is determined, the code of the site incorporated in the delivery route can be specified. For example, the agency code is (10-72), the sender-side collection / delivery base code is (21-34), the sender-side regional delivery base code is (21-80), and the receiver-side regional delivery is If the location code is (43-12), the receiver's collection / delivery location code is (45-95), and the delivery location code is (62-12), the information in which these are arranged, ie, (10 -72, 21-34, 21-80, 43-12, 45-95, 62-12) is generated as the order information.

Next, the disclosed data and the secret data are selected (S6). In this embodiment , the order information generated in S5 is selected as disclosure data (data that can be grasped by the reading device 110), and among the request information input by the sender, the name, address, and telephone number of the receiver Information, the name, address, and telephone number information of the sender, and the item name information of the goods related to delivery are selected as confidential data (data that cannot be grasped by the reading device 110). In S6, a process of rearranging the selected disclosure data and confidential data is also performed.

  For example, as shown in FIG. 7A, if the elements of the information to be encoded are arranged in the order of disclosure data A, secret data α, disclosure data B, and secret data β, the order of these data is As shown in FIG. 7 (B), the disclosure data A, the disclosure data B, the secret data α, and the secret data β are rearranged in this order. As a result, the disclosed data and the confidential data are collected together, so that the terminal identification code addition process in S102 and the confidential identification code addition process in S103 are facilitated (see FIG. 5).

  After the selection process of S6, a key information generation process is performed (S7). This key information is information necessary for decrypting the first delivery information at the delivery base. The key information can be generated using various known encryption key generation methods. The determined key information is temporarily stored in storage means such as the RAM 5.

  Thereafter, information code generation processing is performed (S8). FIG. 5 is a flowchart illustrating the flow of the generation process. When the generation process is started, first, in S100, each data such as disclosed data and secret data is converted into a JIS basic specification (JIS X 0510: 2004). ) Is encoded. As a result, a disclosed data code encoded as a code word representing data to be disclosed is generated, and a secret data code encoded as a code word representing data to be concealed is generated.

  In the subsequent S101, an error correction code for each data such as disclosed data and secret data is generated in accordance with JIS basic specifications (JIS X 0510: 2004), and further encoded to generate an error correction code.

  Then, in subsequent S102, processing for adding a terminal identification code after the disclosed data code is performed. The end identification code is, for example, “0000” in a 4-bit pattern, and is located immediately after the combined disclosure data code (immediately after the disclosure data code B) as shown in FIG. In FIG. 7C, for the sake of convenience, the disclosed data code is expressed as “disclosed code” and the terminal identification code is expressed as “end terminal”.

  Further, in S103, a process of adding the secret identification code immediately after the termination identification code is performed. In the process of S103, the secret identification code is arranged immediately after the termination identification code, so that the data code arranged after the termination identification code is “coded as a code word representing the data to be kept confidential”. "Is explicitly expressed. Thereby, when the QR code Q generated by this processing is decoded by the reading device 10 at the delivery base, it can be recognized that the confidential data code is included in the QR code Q.

  In the next S104, a process is performed in which the data length of the secret data code is calculated and obtained, and the data length encoded is added immediately after the secret identification code. As a result, the area and range in which the secret data code is arranged can be known, so that when the QR code Q generated by this process is decoded, it is possible to recognize how far the secret data code is.

  For example, in the example shown in FIG. 7C, the sum of the data length of the secret data code α and the data length of the secret data code β is calculated as the data length and added immediately after the secret identification code. In FIG. 7C, for the sake of convenience, the secret data code is expressed as “secret code”, and the secret identification code is expressed as “secret identifier”.

  In subsequent S105, a process of encrypting the secret data code is performed. In this process, for example, the secret data code is encrypted using a known visual decryption encryption technique (visual decryption secret sharing method). Thereby, the strength of security can be increased as compared with the case where such unencrypted plaintext data is added.

  For example, in the example shown in FIG. 7D, the portion of “encrypted data” constituting the secret data code α is encrypted, and “start digit”, “number of characters”, and “key information inspection data” are also generated. Is done. The “start digit” positioned first corresponds to an address value that can be expressed as the position information of the encrypted confidential data when the top of the print data is set to zero. The next “number of characters” is the number of characters of the encrypted confidential data. As a result, the QR code Q generated by the code generation process is decoded by a QR code reader or the like even when the data records are mixed in the positional relationship in the data record before being encoded as a code word. In this case, the decoded data can be arranged in the positional relationship before encoding based on the positional information.

  The “key information inspection data” added at the end is information that can identify key information (key information generated in the process of S7) used to decrypt the cipher, and is configured by the key information itself. Alternatively, it may be configured by some information that can specify the key information (information obtained by converting the key information according to a determined rule). This key information inspection data is used for decrypting the code when the QR code Q generated by this code generation process is decoded by the reader 10 at the delivery base.

  The secret data code β is also configured in the same manner as the secret data code α, and the same key information as the key information for decrypting the secret data code α (key information generated in the process of S7) as “key information inspection data”. Is added. Instead of this, the secret data of the secret data code β may be encrypted with “other key information” different from the key information of the secret data code α. In this case, the “other key information” "Key information inspection data" for specifying "may be added.

  In subsequent S106, a process of adding a secret data code immediately after the data length is performed. In the example shown in FIG. 7D, the secret data code α and the secret data code β are added after the data length. Further, in S107, in accordance with JIS basic specifications (JIS X 0510: 2004), a process of adding a padding code is performed after the secret data code, and in S108, a process of adding an error correction code is performed. As a result, a data code having the format shown in FIG. 7C is generated.

In S109, a process of generating each cell based on the generated data code and arranging it in the data block shown in FIG. 8 is performed. In the present embodiment , the type 1 QR code shown in FIG. 8 is used, and one side is formed in a square shape of 21 cells (modules). Therefore, position detection patterns and format information (see FIG. In the code area excluding the timing pattern), 26 blocks (A0 to A25) of data blocks configured by arranging 8 cells in 4 rows and 2 columns are arranged.

  For example, in the example shown in FIG. 7C, the disclosed data code A is arranged in A0 to A2, the disclosed data code B is arranged in A3 to A6, and the terminal identification code is arranged in A7. Then, behind this termination identification code, a secret identification code, a data length, a secret identification code, and the like are usually arranged at A8 to A17 corresponding to positions where the padding code is arranged.

  That is, a secret identification code is arranged at A8, a data length is arranged at A9 thereafter, a secret data code α is arranged at A10 to A13, and a secret data code β is arranged at A14 to A17. Then, similarly to the normal QR code, the error correction code is arranged in the last A20 to A25, and the padding code is arranged in A18 to A19 which are vacant portions therebetween. Since A15 and A18 are located across the timing pattern, A15 is divided into A15 and A15 ′, and A18 is divided into A18 and A18 ′.

When the information code generation process shown in FIG. 5 is completed, the information code output process shown in S9 of FIG. 4 is performed. The output process of the information code is a process of outputting the information code (QR code Q) generated for the information processing apparatus accessed by the sender, and the sender uses the information processing apparatus 111 of the dealer as in this embodiment . When the management server 2 is accessed, an information code (QR code Q) generated from the management server 2 to the information processing apparatus 111 is given. The QR code Q is displayed on the monitor 116 of the information processing apparatus 111 and can be printed on a predetermined slip by the printer 130. FIG. 12B shows a state where the QR code Q is printed on the slip.

  Further, a decryption program is assigned to the reader 10 at the delivery base determined by the process of S4 (S10). This processing is processing for enabling the reading device 10 at the delivery base to obtain a decryption program (programs shown in FIGS. 10 and 11 described later). For example, the decryption program is sent from the management server 2 to the reading device 10. The program may be transmitted spontaneously, or may be a process that gives the reader 10 the right to download the decryption process.

  Furthermore, a process of assigning the key information generated in S7 to the reading device 10 at the delivery base determined by the process of S4 is performed (S11). This process is a process that enables the reader 10 at the delivery base to obtain the key information. For example, the key information may be transmitted spontaneously from the management server 2 to the reader 10. The processing may be such that the right to download key information is given to 10.

As described above, in the present embodiment , the management server 2 serving as the “delivery management device” is provided at the management base that manages the delivery of the articles, and the management server 2 serves as the “encryption unit” and the “code generation unit”. A functioning “CPU 3 and a program for executing the flowchart of FIG. 4” are provided. Further, the management server 2 acquires request information including the subject information of the receiver (name, address, telephone number of the receiver) from the sender, and “the program for executing the CPU 3 and the flowchart of FIG. 4” It also functions as “request information acquisition means”. Further, the management server 2 determines a delivery route based on the request information, generates delivery information based on the request information and the delivery route, and “the program for executing the CPU 3 and the flowchart of FIG. It also functions as “route determination means” and “delivery information generation means”. Further, the management server 2 specifies a delivery base based on the determined delivery route, and assigns a decryption algorithm to the reader 10 (first information reader) at the delivery base. The program for executing the flowchart of FIG. 4 corresponds to “allocation means”.

  In addition, the “CPU 3 and the program for executing the flowchart of FIG. 4” corresponding to the “code generation means” are information on the second delivery information as non-encrypted data that can be read by the second information reader at all the relay bases. It is included in the code (QR code Q), so that the order information of the base to deliver the article can be easily obtained at the relay base, and the goods can be transported smoothly at the relay base with good workability. .

  Further, “the CPU 3 and the program for executing the flowchart of FIG. 4” corresponding to “encryption means” and “allocation means” encrypt the first delivery information so that it can be decrypted with specific key information, and deliver A decryption algorithm and key information are both assigned to the base reader 10 (first information reader). According to this configuration, even if the decryption algorithm is acquired by some method, the first delivery information cannot be decrypted without the key information, so that the security of the first delivery information is further strengthened.

  Further, the “CPU 3 and the program for executing the flowchart of FIG. 4” corresponding to the “code generation means” simply includes a data area of the first delivery information and a data area of the second delivery information as information codes. One two-dimensional code (QR code) is generated, and according to this configuration, it is possible to speed up code generation and speed up reading work.

  In addition, the printer 130 provided in the agency store corresponds to an example of “formation unit” that forms the information code (QR code Q) generated by the “code generation unit” on a slip to be attached to an article. That is, the QR code Q generated by the management server 2 is given to the information processing apparatus 111 and is printed on a slip by the printer 130 as “formation means”.

In the present embodiment , the management server 2 obtains a message from the sender. That is, as described above, when the sender inputs a message using the input form of FIG. 6, this message is sent to the management server 2, and the “CPU 3 and FIG. The “program for executing the flowchart” corresponds to an example of “message acquisition means”. The management server 2 generates print data for recording the generated QR code Q and the acquired message on a slip.

  As shown in FIG. 12A, a “slip” used for delivery is provided with a code recording area 141 for recording a QR code Q and a message recording area 142 for recording a message by a sender. The print data generated by the server 2 is arranged so that QR code Q is recorded in the code recording area 141 of the slip and the acquired message is recorded in the message recording area 142 at the time of printing. It is configured as data for determining the size and the like.

  The print data including the message is given to the printer 130 via the information processing apparatus 111, and the QR code Q and the message are printed together on the slip by the printer 130 as shown in FIG. As a result, a message other than information that can objectively identify the sender and the receiver (information that cannot be objectively identified and understood only by the parties) and the QR code Q can be displayed. .

  In the above example, both the QR code Q and the message are printed on the slip by the printer 130. However, only the QR code Q may be printed by the printer 130. In this case, as shown in FIG. 12C, the sender can write information in the message recording area 142 by handwriting or the like.

  Further, in the above example, as shown in FIG. 12A, a slip in which the code recording area 141 and the message recording area 142 are allocated in advance is illustrated, but such an area may not be allocated. In short, as long as both the generated QR code Q and the acquired message can be printed on the slip, the purpose of attaching the QR code Q and the message to the article can be achieved.

3. Processing at Relay Station Next, processing at the relay station will be described.
FIG. 9 is a flowchart illustrating the flow of the reading process at the relay site. This process is started by a control circuit and a memory (similar to the control circuit 40 and the memory 35) that are activated when the QR code reader 120 provided at the relay base is turned on. Note that the initial setting process for clearing the work area of the memory and the image data storage area for storing image data, and clearing predetermined flags, counters, etc. is omitted.

  First, in S200, processing for acquiring image data is performed. This process is a process of reading the above-described QR code Q attached to an article and storing image data of the QR code Q in a memory. In the field of QR code readers, the process of acquiring QR code Q image data and storing it in a memory is well known, and details thereof are omitted.

  Next, a process of reading the image data stored in the memory and detecting a position detection pattern is performed (S201). That is, as conceptually shown in FIG. 8, since the QR code Q is provided with position detection patterns at its three corners, these detections are performed, and further the code outer shape of the QR code Q is detected ( S202).

  Further, a process for calculating the center coordinates of each cell is performed in S203, and a process for determining the black and white of each cell is performed in S204. This makes it possible to recognize the format information shown in FIG. 8 (the hatched portion shown in FIG. 8) and the data block, and in the subsequent S205, if there is a missing data block, the block can be error-corrected. Judge whether there is.

  If it can be determined in S205 that error correction is possible (S205; OK), error correction is performed and subsequent decoding processing in S206 and subsequent steps is performed. On the other hand, if it cannot be determined in S205 that the error can be corrected (S205; NG), the error cannot be corrected. Therefore, the process proceeds to step S200, and the image data is acquired again, and steps S202 to S205 are performed. Perform each process.

  In the decoding process after S206, first, a process of setting 0 (zero) to the counter n is performed. The counter n functions as a variable indicating the order of data codes constituting the QR code Q in the decoding process. In subsequent S207, processing for obtaining the nth data code pointed to by the counter n is performed. Further, in S208, processing for determining whether or not the nth data code acquired in S207 is a terminal identification code is performed. If it is not possible to determine that the data code is the termination identification code (S208; No), the normal data code still exists before the termination identification code, so the process proceeds to the subsequent S209 and the next The code number i of the data code, that is, the (n + 1) th data code is acquired. As described above with reference to FIG. 7D, this is based on the fact that the number of characters is stored at the position corresponding to the second character of the data code. JIS X 0510: 2004), “8.4 Data encoding”.

  After performing the process of acquiring the code number i in S209, in the subsequent S210, the process of acquiring the data code for the number of characters (i) is performed, and in S211, the data code, that is, the disclosed data code (disclosed) Data code encoded as a code word representing the data to be decoded) is decoded.

  When the decoding process in S211 ends, in S212, the process of setting “n + i + 1” to the counter n is performed so that the counter n indicates the next data code, and the process returns to S207 again to change the nth data code. Processing to obtain is performed.

  On the other hand, if it is determined in S208 that the nth data code acquired in S207 is a terminal identification code, the process proceeds to Yes in S208, and the process ends.

  As described above, since the QR code reader 120 at the relay base is not provided with an algorithm for reading the secret data code incorporated after the termination identification code, it is usually placed in front of the termination identification code and originally decoded. Only the data code is decoded. The data embedded in front of the terminal identification code does not contain any specific information (sender name, address, phone number, recipient name, address, phone number, etc.) that identifies the sender and receiver. The name, address and telephone number of the sender and receiver will not be disclosed at the site.

  On the other hand, the disclosed data code that can be read by the QR code reader 120 is obtained by encoding the second delivery information including the order information of the bases. “10-72, 21-34, 21-80, 43-12” , 45-95, 62-12 "is displayed on the liquid crystal display of the QR code reader 120 or the monitor 116 of the information processing apparatus 111. Therefore, the next base can be easily specified at each relay base, and can be delivered to the next base without any trouble. The liquid crystal display and the monitor 116 of the QR code reader 120 correspond to an example of “order information display unit”.

4). Processing at Delivery Base Next, processing at the delivery base will be described with reference to FIGS.
FIG. 10 is a flowchart schematically illustrating the flow of the reading process performed by the reading device at the delivery base. FIG. 11 is a flowchart schematically illustrating the decoding process of FIG.

  Since S301 to S306 in FIG. 10 are the same as the processes in S200 to S205 in FIG. 9, detailed description thereof is omitted. If it can be determined in S306 that error correction is possible (S306; OK), error correction is performed and the subsequent decoding processing in S307 is performed. On the other hand, if it cannot be determined in S306 that error correction is possible (S306; NG), error correction cannot be performed. Therefore, the process proceeds to S301, image data is acquired again, and steps S301 to S306 are performed. Do.

  On the other hand, if it can be determined that error correction is possible, the process proceeds to OK in S306, and the decoding process of S307 is performed. The details of the decoding process in S307 are shown in FIG. 11, and will be described with reference to FIG. As shown in FIG. 11, in the decoding process, first, a process of setting 0 (zero) to the counter n is performed in step S401. The counter n functions as a variable indicating the order of data codes constituting the QR code Q in the present decoding process.

In S402, processing for obtaining the nth data code pointed to by the counter n is performed. In subsequent S403, processing is performed to determine whether or not the nth data code acquired in S402 is a terminal identification code. If it is not possible to determine that the data code is the termination identification code (S403; No), the normal data code still exists before the termination identification code. Data code, i.e., the code number i of the (n + 1) -th data code. This is based on the fact that the number of characters is stored in the position corresponding to the second character of the data code, as described with reference to FIG. 7D in the first embodiment . It is described in “8.4 Data Encoding” in JIS Basic Specification (JIS X 0510: 2004).

  When the code number i is acquired in S404, in the subsequent S405, a process for acquiring the data code for the number of characters (i) is performed, and in S406, the data code, that is, the disclosed data code (the code representing the data to be disclosed). A process of decoding (decoding) a data code encoded as a word is performed.

  When the decoding process in S406 ends, in S407, a process of setting “n + i + 1” to the counter n is performed so that the counter n indicates the next data code, and then the process returns to S402 again to return the nth data Processing to obtain the code is performed.

  As described above, in S402 to S407, a process of obtaining and decoding a normal data code (that is, a disclosed data code) arranged in front of the terminal identification code and originally decoded is performed.

  On the other hand, in the determination process of S403, when it is determined that the data code acquired in S402 is a termination identification code (S403; Yes), the process proceeds to S408 and n is incremented (S408).

  Thereafter, the nth data code is acquired (S409), and it is determined whether or not the acquired data code is a secret identification code (S410). If it is determined in S410 that the code is a secret identification code, a secret data code exists after the secret identification code. Therefore, the process proceeds to Yes in S410, and the counter n is determined in S411. Is advanced to the head position of the secret data code (that is, n = n + 2 is set).

  If it is not possible to determine that the data code is a secret identification code in the determination process of S410 (for example, the read QR code is a general-purpose QR code (a padding code is placed after the termination identification code) In this case, since the secret data code is not included in the QR code Q, the process proceeds to No in S410, ends the decoding process, ends S307 shown in FIG. The reading process ends.

  On the other hand, after the process of S411 is performed, a process of obtaining the code number j of the encrypted data is performed based on the (n + 1) th data code (S412). This is also based on the fact that the number of characters is stored in the second equivalent position of the secret data code, as in S209 (see FIG. 7D).

  After the code number j is acquired in S412, in the subsequent S413, processing for acquiring the data code for the number of characters (j) is performed, and in S414, the counter n is pointed to indicate the next key information inspection data. Is performed (that is, n = n + j + 2), and in step S415, n-th key information inspection data (key identification information) is acquired.

  Then, a process is performed to determine whether or not the key information given from the management server 2 is compatible with the key information inspection data acquired in S415 (S416). Note that the key information may be acquired in advance by the reader 10 in response to the spontaneous transmission from the management server 2 and stored in the storage means (hard disk drive 17 or the like), or from the reader 10 at a predetermined time. The management server 2 may be accessed to obtain key information. For example, key information may be acquired from the management server 2 when performing the determination processing in S416.

In the determination process of S416, when it is determined that the key information given from the management server 2 matches the key information inspection data, the process proceeds to Yes in S416, and the process of decrypting the encrypted data is performed in S417. In the present embodiment , the decryption program (the program shown in FIGS. 10 and 11) is assigned to the reading device 10 by the management server 2 that has encrypted the QR code Q as described above. Decryption processing corresponding to encryption is performed.

  On the other hand, if it is determined in step S416 that the key information is not compatible, the process proceeds to No in step S416, and the next secret data code is acquired without decrypting the secret data code. And the counter n is set to n + 1.

  On the other hand, when the encrypted data is decrypted in S417, processing for decrypting the secret data code is performed. That is, since the encrypted data is decrypted in the previous S417, in this S418, a process of decoding (decoding) the secret data code based on the decrypted encrypted data is performed.

When the decoding process of S418 ends, in S419, a process of setting “n + 1” to the counter n is performed so that the count n indicates the next data code, and in the subsequent S420, a process of acquiring the nth data code is performed. Done. Further, in S421, a process is performed to determine whether or not the nth data code acquired in S420 is a padding code. As a result, if the n-th data code is a padding code (S421; Yes), the QR code Q does not contain any more secret data code. The process ends, step S307 shown in FIG. 10 ends, and the reading process in FIG. 10 ends. In the present embodiment , the CPU 13 and the program shown in FIG. 11 correspond to an example of “decoding means”.

  On the other hand, if it is not determined in S421 that the n-th data code is a padding code (S421; No), the n-th data code is a secret data code, so the process proceeds to S412. The same processing as described above is performed by acquiring the code number j for the (n + 1) th data code again.

  As described above, according to the reader 10 provided at the delivery base, a secret data code (secret data code) is originally placed in the code area (empty portion of the code area) after the terminal identification code where only the padding code is arranged. This secret data code can be decoded even if. The first delivery information related to the decoded confidential data code is displayed on the liquid crystal display 46 of the QR code reader 20 and the monitor 16 of the information processing apparatus 11, so that the worker at the delivery base receives it. You will be able to know the person's name and address. The liquid crystal display 46 and the monitor 16 correspond to an example of “subject information display means”.

As described above, according to the configuration of the present embodiment , the display of the content of the subject information is prohibited in principle by the encryption of the first delivery information, and the content display of the subject information is prohibited even at the relay base in the middle of the delivery. The As a result, personal information is not disclosed to those who are not related to delivery, and the personal information of the sender and receiver cannot be obtained. Can be made more stringent. On the other hand, since the second delivery information including the order information of the base can be read at the relay base, the next base can be identified based on the order information, and the delivery from the relay base to the next base is satisfactory without any problem. Can be done. Further, at the delivery base, the first delivery information is decrypted by the decrypting means, and the subject information can be displayed. That is, the personal information is disclosed within the minimum necessary range, and as a result, the delivery of the article from the delivery base to the recipient is performed satisfactorily without any trouble.

  In addition, a management server 2 (delivery management device) is provided at a management base that manages the delivery of articles. The management server 2 includes an “encryption unit” and a “code generation unit”, and from the sender to the receiver. Request information including the subject information is determined, a delivery route is determined based on the request information, and delivery information is generated based on the request information and the delivery route. That is, as long as the sender gives the request information to the management server 2, an encrypted information code can be generated on the management server 2 side. Therefore, when the information code is created, the sender has a special configuration and excessive work. There is no burden. In addition, the management server 2 is configured to identify a delivery base based on the determined delivery route and assign a decryption algorithm to the reader 10 (first information reader) at the delivery base. Therefore, it is possible to satisfactorily realize a configuration in which only a specific base directly involved in delivery can decode the first delivery information.
