DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings showing the embodiments. FIG. 1 is a schematic diagram for explaining a first embodiment of a method and system for confirming receipt of an article according to the present invention.

In the present invention, it is assumed that the article 100 is sent from the article dispatcher 110 to the destination 140, and the transportation company A12
0 and the transportation company B130 transport the goods 100 in this order, and the distribution management center 150 manages the entire distribution.

It should be noted that the destination 140 is the ultimate recipient of the article 100, but the intermediate shipping company A120 is the
And the carrier B130 is the carrier A
Become a recipient from 120. Further, although not shown in the following embodiment, a recipient such as a distributor / distributor, a temporary manager for relaying articles, such as an in-house distribution manager, may also be a recipient.

The goods dispatcher 110 has a printer 111 and an encryption device 112, the transport company A 120 has a scanner 121 and a decryption device 122, the transportation company B 130 has a scanner 131 and a decryption device 132, and the destination 140 has a scanner. The logistics management center 150 communicates the 141 and the decryption device 142 with the receipt confirmation device 151
Respectively.

The receipt confirmation device of the distribution management center 150
151, between the encryption device 112 of the goods dispatcher 110, the decryption device 122 of the transportation company A120, and the transportation company B130.
Of the destination 140 and the decryption device 142 of the destination 140 are communicably connected via lines L1, L2, L3 and L4, respectively.

A record carrier 102 such as a label, on which a two-dimensional code 101 is printed, is attached to the article 100 sent from the article dispatcher 110 to the destination 140. FIG. 2 is a schematic diagram showing the contents of information recorded in the two-dimensional code 101. In the two-dimensional code 101, article content information 201, destination information 202, transport company ID 203 (for transport company A120), 204 (for transport company B130), and destination ID 205 are recorded. In the example shown in FIG. 2, two IDs for the shipping company, 203 and 204, are recorded because this corresponds to the schematic diagram of FIG. If is one or three, the required number of shipping company IDs is recorded.

Here, to attach the label 102 as a record carrier on which the two-dimensional code 101 is printed and recorded to the article 100 means that the label 102 as the record carrier is not easily separated while the article 100 is being transported. For example, it includes not only the state of being fixed by gluing but also the state of being fixed to a pallet, a packing material, or the like.

When shipping the article 100 from the article dispatcher 110, the distribution management center 150 issues the transport company IDs 203 and 204 and the destination ID 140 relating to the article 100. The goods dispatcher 110 adds the goods content information 20
1 and destination information 202 are added and input to the encryption device 112. The encryption device 112 encrypts the carrier IDs 203 and 204 of the input information and the destination ID 140 to create an encrypted character string, and converts it into a two-dimensional code 101 together with other information. The label is printed on the label 102 by the printer 111. The label 102 on which the two-dimensional code 101 created in this way is printed is attached to the article 100.

In this case, the encrypting device 112 encrypts only the carrier IDs 203 and 204 and the destination ID 140 in the input information.
1 and the destination information 202 may also be encrypted. In this case, the confidentiality of the information is ensured.

Next, the shipping company A120 sets the goods dispatcher 110
, And delivers the goods 100 to the shipping company B130. When the goods 100 are received from the goods dispatcher 110, the shipping company A120 sends the two-dimensional code 101 to the scanner 121.
Is read, and the result is input to the decryption device 122 and decrypted to generate a plaintext. Based on the plain text, the transportation company A 120 confirms the destination, extracts the transportation company ID 203 and sends it to the reception confirmation device 151 of the distribution management center 150. If the logistics management center 150 can confirm the carrier ID 203 transmitted from the carrier A120, the goods 10
Since 0 means that the goods have been sent from the goods dispatcher 110, the charges for the goods 100 are paid to the goods dispatcher 110.

Next, the article 100 is transferred to the transport company B130 by the transport company A120, and at this time, the two-dimensional code 101 is read by the scanner 131 at the transport company B130 as described above, and the result is decoded. Input to 132 and decrypt it to generate plain text. By this plain text,
The shipping company B130 checks the destination and also checks the shipping company ID 204
And sends it to the receipt confirmation device 151 of the distribution management center 150. If the logistics management center 150 can confirm the transport company ID 204 transmitted from the transport company B130,
This means that the goods 100 have been reliably transferred from the shipping company A120 to the shipping company B130.
Is charged by the transportation company A120.

Finally, the article 100 is delivered from the shipping company B130 to the destination 140. At this time, the two-dimensional code 101 is read by the scanner 141 at the destination 140, and the result is input to the decryption device 142 and the plaintext is input. Is generated.
The destination 140 extracts the destination ID 205 from the plain text and sends it to the reception confirmation device 151 of the distribution management center 150. In the distribution management center 150, the destination ID transmitted from the destination 140
If 205 can be confirmed, it means that the article 100 has arrived at the destination 140, and the transportation cost of the article 100 by the carrier B130 is charged.

Thus, the article 100 has been dispatched from the article dispatcher 110 and arrived at the destination 140.
Receives the destination ID 205 from the logistics center 150
The timing of transmission to 1 is the time when the destination 140 has received the acceptance, and at this time, after the receipt confirmation device 151 receives the destination ID 205, the goods dispatcher 110 requests the destination 140 for the price of the goods 100, and The company A120 and the transportation company B130 may be required to pay the transportation cost.

There is also a method of generating a two-dimensional code 101 by simultaneously encrypting the data when the data is converted into a two-dimensional code. Therefore, when such a two-dimensional coding method is used, only the information to be encrypted in the goods dispatcher 110 is input to the printer 111, so that the encrypted
Since the dimensional code 101 is generated and printed on the label 102, the encryption device 112 of the article dispatcher 110 is not required.
When the two-dimensional coding method as described above is used, the decryption can be performed when the two-dimensional code 101 is read by the scanner, and if the encryption key is not known, the two-dimensional code 101 is used. Can't even read
The functions of the decryption device 122 of the transport company A120, the decryption device 132 of the transport company B130, and the decryption device 142 of the destination 140 are included in the respective scanners 121, 131, 141.

Next, FIG. 3 is a schematic diagram for explaining the second embodiment of the method and system for confirming the receipt of articles of the present invention. FIG. 3 shows the recorded contents of a two-dimensional code.
5 and a schematic diagram of FIG. 5 for explaining the flow of encryption.

In the present embodiment, it is assumed that the package 301 is sent from the transport requester 300 to the destination 340, and the transport company C310, the transport company D320, and the transport company E330 carry the package 301 in this order. Transportation company C31
0 shall be managed.

The transportation company C 310 has a scanner 311 and a decryption device 312, a printer 313 and a receipt confirmation device 314, and the transportation company D 320 has a scanner 321 and a decryption device 322.
The shipping company E330 has a scanner 331 and a decryption device 33
And 2 respectively. The transport company D320 and the transport company E330 are affiliated companies of the transport company C310, the transport company D320 is mainly in charge of long-distance transport, and the transport company E330 is in charge of collection and delivery in a specific area. In addition, the receipt confirmation device 31 of the transportation company C310
4 and the decryption device 322 of the transport company D320 and the decryption device 332 of the transport company E330 are communicably connected by lines L5 and L6, respectively. Further, in the transportation company C310, the receipt confirmation device 314 and the printer 313
It is assumed that the decryption device 312 is connected to, for example, a LAN line.

The transportation company C310 sends the package from the carrier 300
Upon receiving 301, a two-dimensional code 304 is created and printed on a label 302 and a receipt 303 by a printer 313. As shown in FIG. 4, the two-dimensional code 304 includes package content information 401, destination information 402, an encryption ID 403 generated by the reception confirmation device 314, and a public encryption key 40.
4 is recorded. However, information other than the encrypted ID 403 is plaintext that is not encrypted. Reference numeral 404
Is an error check code, and may be omitted when not used.

The label 302 printed in this manner is affixed to the luggage 301, and is transported together with the receipt 303.
Although not shown, the address, name, and contents of the carrier 300 and the destination 340 are printed in plain text in addition to the two-dimensional code 304 on the receipt 303. There is also a field to have your receipt stamped.

A secret key K _C is issued to the transport company C 310, a secret key K _D is issued to the transport company _D 320, and a secret key K _E is issued to the transport company E 330 by the receipt confirmation device 314. Further, the public encryption key 404 described in the two-dimensional code 304
Is K _P and the secret key used by the receipt confirmation device 314 is K _O
And the encryption ID generated inside the receipt confirmation device 314 is S _O
And

Here, when the encryption by the RAS method is used, the secret key K _O and the public encryption key K
_{Since the} encryption key K ′ _O can be created from _P , the encrypted ID S can be obtained by encrypting the encryption ID S _O using the encryption key K ′ _O. This encrypted ID
S is the encrypted ID 403 of the two-dimensional code 304.

Next, the transport company D320 receives the package 301 and the receipt 303 from the transport company C310, and
321 causes the two-dimensional code 304 to be read. This allows
The shipping company D320, decryption device 322 to obtain the public key K _P and encryption IDS. Decryption device 322 previously issued by that secret key K _D with the public key K _P encryption and a decryption key K '
_D is obtained, and the encrypted IDS is decrypted to obtain S _D, which is transmitted to the acknowledgment device 314 of the carrier C310. Receipt confirmation device 31
In 4, since the secret key K _D is known, it is possible to determine whether S _D is correct.

Next, the transportation company E330 is changed to the transportation company D320.
Received the package 301 and the receipt 303 from the
The two-dimensional code 304 is read by 331. This allows
In the transportation company E330, the decryption device 332 obtains a decryption key K ' _E from the secret key K _E issued in advance and the public key K _P recorded in the two-dimensional code 304, and obtains the encryption ID.
It decodes S to obtain S _E , and transmits it to the acknowledgment device 314 of the transportation company C 310. In the receipt confirmation device 314, the secret key K _E
Is known, it is possible to determine whether S _E is correct or not.

The shipping company E 330 delivers the package 301 to the destination 340, and at that time, has the receipt stamped on the receipt receipt 303 and sends it to the shipping company C 310. In the transportation company C310, the receipt stamp of the receipt 303 is confirmed, and the two-dimensional code 304 printed on the receipt 303 is read by the scanner 311. Then, in the decryption device 312 of the transportation company C310, the public encryption key 40 of the two-dimensional code 304
4 obtains the decryption key K _'C and a public encryption key K _P that is recorded in advance issued by that secret key K _C in encrypted
The IDS is decrypted to obtain S _C, which is transmitted to the acknowledgment device 314.

The acknowledgment device 314 of the transportation company C 310
Upon receiving _C , the transportation requester 300 charges the transportation company C310 to pay a transportation fee. At the same time, the transportation company C310 pays the transportation fee to the transportation company D320 and the transportation company E330.

If, for example, the transport company D320 has not only a long-distance transport department but also a department that performs delivery to some areas, the transport company D320 directly delivers the package 301 to the destination 340. Sometimes it is more efficient to do so.
In such a case, acknowledgment device 314 is not ho not received S _E at the time of receiving the S _C.
Therefore, by this, the transportation company C310 can set the transportation company D32.
Since it is possible to determine that 0 has delivered the package 301 directly to the destination 340, the transportation fee is paid only to the transportation company D320.

As described above, the transportation fee is calculated by the receipt confirmation device 314.
Can be dynamically managed, so that requests to other carriers can be dynamically changed,
The efficient delivery of 301 becomes possible.

In the above-described embodiment, since the transportation company C310 has the receipt confirmation device 314, the scanner 311 and the decryption device 312, the secret key K _O for the receipt confirmation device 314 and the decryption Even if it is the same as the secret key K _C for the device 312, no problem occurs.

Further, in the above-described embodiment, the decryption device of each transport company generates a decryption key from a secret key and a public key issued to each transport company in advance. However, this processing may be performed by another device, in which case the security can be further improved.

In the above-described embodiment, a slip is also required in the form of a receipt 303. However, in comparison with the conventional method of controlling the transportation costs of each transportation company using expensive copy-type slips, the present invention has a
3 can be plain paper, and when using copy-type slips, the number of slips can be reduced, so that costs can be saved.

Further, the receipt 303 is stored in the
In the case where the form is like a stub of the label 302 attached to 1, it is not necessary to carry the slip separately from the luggage 301.

Note that S _C , S _D , and S _E are generally ASC
Since it is not an II character string, if an error check code 404 such as parity and CRC is also recorded in the two-dimensional code 304, error detection at the time of reading by each scanner becomes possible.

More specifically, since the reception confirmation device 314 can obtain S _C , S _D , and S _{E in} advance,
CRC codes C _C , C _D , and C _E are obtained, and added to the two-dimensional code 304 as an error check code 404 and recorded. Then, the transport company D320 reads the two-dimensional code 304 on the label 302 by the scanner 321 to obtain _SD, and also obtains the CRC code from the error check code 404. Then, when the CRC code matches with C _D , S _D is transmitted to acknowledgment device 314. If they do not match, it is considered that an error has occurred due to, for example, the label 302 being contaminated, and the
The above two-dimensional code 304 is read, and the same processing as described above is retried. Nevertheless the approval of exception processing, for example, manual processing if the CRC codes do not match with the C _D.

As described above, not only the frequency of communication to the reception confirmation device 314 is reduced, but also it is possible to confirm the error early.

Since the receipt confirmation device 314 can be realized as a part of the host computer, for example, the package contents information 401 and the destination information 402 are stored in the host computer, and the package ID is two-dimensionally replaced. code
May be recorded in 304. In this case, the shipping company C310
The other transportation companies D320 and E330 can read the destination from the host computer according to the package ID. When such a method is employed, the size of the label 302 can be further reduced.

Further, it is possible to provide the encrypted ID 403 with a function as a package ID without using the package ID as described above. In this case, the encrypted IDS is obtained by encrypting a character string including the baggage ID.
Is known for K _C , K _D , and K _E , so
It is possible to reproduce the luggage ID from S _C , S _D , S _E.

When a wireless ID tag is used as the record carrier of the present invention, the receipt can be confirmed even at a position away from the record carrier. Specifically, as shown in the schematic diagram of FIG. 6, when the transportation means 503 such as an automobile and a truck passes through the gate 501 with a plurality of luggage 301 loaded thereon, it is provided at the gate 501. Since the receiving device 502 reads the recorded content of the wireless ID tag 305 as a record carrier attached to each package 301, it is possible to automatically confirm receipt of the package 301.

Conversely, when a plurality of packages 301 are accumulated in a certain area, by bringing a receiving device having the same function as the receiving device 502 close,
It is also possible to collectively confirm receipt of 301.

[0076]

As described in detail above, according to the present invention,
Receipt confirmation can be performed without using a slip, and both the amount of information processing and the amount of transfer can be reduced, so that the system configuration is inexpensive.

Also, with a small amount of information, it is possible to reliably confirm that the article to be transported has reached the recipient.

Further, when information (evaluation function) for judging whether or not the result of decryption is regarded as a code is recorded on the record carrier, the recipient side may read the record carrier for some reasons. Even if the data is corrupted,
Exception processing can be performed before transmission to the receipt confirmation device.

Further, when a plurality of recipients exist, a key for decrypting the code is issued in advance to each recipient, so that a different type of record carrier or a different receipt confirmation is provided for each recipient. There is no need to prepare equipment.

Further, since the results of decrypting the code recorded on the record carrier by the keys issued to the respective recipients are different from each other, it is not necessary to prepare encrypted data for each recipient. It is also possible to prepare encrypted data and decrypt it with a key issued to each recipient. In this case, the decryption result differs for each recipient, but the receipt confirmation device can easily calculate the decryption result using each key, and thus can confirm receipt. Also, in this case, there is no need to prepare a different key for each recipient, so the amount of encrypted data may be reduced, especially if the goods are passed to the final recipient via multiple recipients. Only a small amount is required, and the size and cost of the record carrier can be reduced. In this case, the encrypted data may not be a single one. For example, the intermediate receivers may be grouped and a single encrypted data may be used in each group.

Further, for encrypting and decrypting data,
For example, using a public key encryption method disclosed in RSA, etc., a public key is issued to each recipient, and a private key is issued to each recipient.Therefore, a key for decrypting encrypted data is provided for each recipient, and Since the security is different for each article, the security of the encryption is further enhanced. Conversely, if the security only needs to be maintained at a certain level, it is possible to shorten the encryption information, so that it is possible to reduce the amount of data to be recorded on the record carrier.

Further, since the information is printed and recorded on the record carrier using the two-dimensional code, it is possible to record the information in a small area, and since the label paper and the plain paper can be used, the running can be performed. Costs are reduced.

Further, since a radio ID tag is used as a record carrier, it is possible to confirm receipt even at a position distant from the record carrier. Therefore, it is possible to collectively confirm the receipt of articles accumulated in a certain range or automatically confirm receipt of articles passing through the gate.

Further, according to the record carrier of the present invention, it is possible to decrypt information necessary for transportation only when a legitimate recipient receives an article, thereby improving security.

Further, the security can be improved because the receipt can be confirmed only when the legitimate recipient has received the article and successfully decrypted the article.

Further, even if the information to be recorded has been destroyed for some reason, it is possible to immediately take measures such as exception processing when the recipient reads the record carrier.

Furthermore, since information is printed and recorded using a two-dimensional code, it is possible to record information in a small area, and since label paper and plain paper can be used, running costs are reduced. .

Further, since the radio ID tag is used as the record carrier, the receipt can be confirmed even at a position away from the record carrier. Therefore, it is possible to collectively confirm the receipt of articles accumulated in a certain range or automatically confirm receipt of articles passing through the gate.
