Description

  The present invention relates to a slip processing system, a reading device, and a program.

  Conventionally, a two-dimensional code reader such as a handy terminal is known. A two-dimensional code reader reads a two-dimensional code by analyzing an image of a two-dimensional code photographed by an image sensor such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor).

  The two-dimensional code can be encrypted, and the two-dimensional code itself has encryption standards defined, and the two-dimensional code is encrypted by encrypting the data using a common key method and converting it to a two-dimensional code. There was something that realized a two-dimensional code. By reading these two-dimensional codes with a decryption-compatible scanner, the two-dimensional codes are decrypted and read using an encryption standard or a common key method.

  In addition, depending on the two-dimensional code, both the public data and the non-public data are included in one two-dimensional code, and when reading with a general-purpose scanner, only the public data can be obtained. A configuration is also known in which non-public data can be acquired when reading with a dedicated scanner.

  There is also known an identity verification system that synthesizes encrypted data of a signature image and encrypted data of character data of personal identification information such as an ID number, and two-dimensionally encodes the data (for example, patent literature). 1). At the time of verification, the printed two-dimensional code is scanned with a scanner, decoded and decoded to obtain and display a signature image and character data, the displayed signature image and character data, and a user's handwritten signature and character The person in charge of collation visually confirms that the person is authenticated if the collation is successful.

  However, in the conventional cryptanalysis-compatible scanner, it is necessary to input a password when reading the two-dimensional code. For this reason, the reading operation becomes complicated and there is a risk of password leakage. Therefore, by storing the password in the decryption scanner, the complexity of the operation is eliminated. However, in this case, anyone can use the decryption scanner to decrypt the password.

  In addition, in the conventional configuration in which a two-dimensional code including public data and non-public data is read by a dedicated scanner, a password is not required for verification, but if the dedicated scanner is stolen, who has the dedicated scanner? But I could read private data.

  In addition, even when the conventional two-dimensional code including signature image and character data is read by a scanner, if the scanner is stolen, anyone with the scanner can read the signature image and character data in the two-dimensional code. I was sorry. Furthermore, there has been a request for enabling a predetermined two-dimensional code to be read by an appropriate reading device.

  Next, the operation of the slip processing system 1 will be described with reference to FIGS. FIG. 7 shows a flowchart of the pre-registration process executed by the reading device 30.

FIG. 11 shows a flowchart of the two-dimensional code reading process executed by the reading device 30. FIG. 12 shows a specific example of the two-dimensional code reading process.

  First, the pre-registration process executed by the reading device 30 will be described with reference to FIG. The pre-registration process is a process for registering information used for encryption / decryption of a two-dimensional code. It is assumed that a handwritten signature is entered in advance on a sheet by a sign registration applicant and a sheet including the handwritten signature is prepared.

  In the reading device 30, for example, triggered by receiving an input of a pre-registration process execution instruction from the user via the operation unit 32, the CPU 31 reads out a pre-registration program that is read from the ROM 35 and appropriately expanded in the RAM 33. Pre-registration processing is executed in cooperation with 351.

  First, the CPU 31 initializes the sign / key table 50 stored in the flash memory 37 (step S11). Then, the CPU 31 scans the previously prepared paper by the scanner unit 38 in response to the pressing input of the trigger key 32A of the operation unit 32, acquires the image data of the handwritten signature, and stores it in the RAM 33 (step S12). ). Then, the CPU 31 identifies a signature from the signature image of the image data acquired in step S12 (step S13). The signature identification method is the identification method of a general handwritten signature recognition technique. In step S13, for example, feature data indicating the overall and local feature values of the signature is acquired from the signature image. The feature data is signature stroke data or the like.

  Then, the CPU 31 compares the signature identified in step S13 with the signatures 52 of all records in the signature / key table 50 to collate the signature (step S14). In step S14, for example, signature verification is performed by comparing the signature feature data acquired in step S13 with the signature 52 feature data. Then, the CPU 31 determines whether or not the signature acquired in step S12 is unregistered in the signature / key table 50 based on the signature collation result in step S14 (step S15).

  When the signature is not registered (step S15; YES), the CPU 31 creates an encryption key and a decryption key corresponding to the image data of the signature acquired in step S12 (step S16). In step S16, for example, a new registration number is assigned to the image data of the handwritten signature, an encryption key of an arbitrary character string is created based on this registration number, and a decryption key that is paired with this encryption key is created. Is done. The decryption key is created by a general public key encryption technique.

  Then, the CPU 31 newly uses the signature image data, the encryption key, and the decryption key acquired in steps S12 and S16 as new records of the sign 52, the encryption key 53, and the decryption key 54 in the sign / key table 50. Is added together with the registration number 51 (step S17).

  Then, the CPU 31 determines whether or not to end the sign registration according to the presence / absence of a sign registration end instruction input via the operation unit 32 (step S18). When sign registration is not completed (step S18; NO), the process proceeds to step S12. If the signature is not unregistered (step S15; NO), the CPU 31 displays on the display unit 34 that the signature has been registered (step S19), and proceeds to step S18.

  When sign registration is to be ended (step S18; YES), the CPU 31 wirelessly transmits the encryption key 53 and the registration number 51 of the additional record of the sign / key table 50 to the slip printing apparatus 10 via the communication unit 36 ( Step S20), the pre-registration process is terminated.

  In addition, it is good also as a prior registration process which deleted step S11.

  Next, an encryption key table update process executed by the slip printing apparatus 10 will be described with reference to FIG. The encryption key table update process is a process of receiving the encryption key and the registration number from the reading device 30 and updating the encryption key table corresponding to the pre-registration process.

  In the slip printing apparatus 10, for example, triggered by the reception of the registration number and the encryption key from the reading device 30 via the communication unit 16, the CPU 11 reads the encryption from the ROM 15 and expands the data appropriately in the RAM 13. The encryption key table update process is executed in cooperation with the key table update program 151.

  First, the CPU 11 determines whether or not reception of a registration number and an encryption key has been completed from the reading device 30 via the communication unit 16 (step S31). If the registration number and the encryption key have not been received (step S31; NO), the process proceeds to step S31. When reception of the registration number and the encryption key is completed (step S31; YES), the CPU 11 uses the registration number and encryption key received in step S31 as the new encryption key table 60 stored in the flash memory 17. Is added as a registration number 61 and an encryption key 62 of the new record (step S32), and the encryption key table update process is terminated.

  Next, the two-dimensional code printing process executed by the slip printing apparatus 10 will be described with reference to FIGS. 9 and 10. The two-dimensional code printing process is a process for creating and printing a two-dimensional code.

  In the slip printing apparatus 10, for example, the CPU 11 is read from the ROM 15 and appropriately expanded in the RAM 13 when triggered by the input of a two-dimensional code printing process execution instruction from the user via the operation unit 12. A two-dimensional code printing process is executed in cooperation with the dimension code printing program 152.

  First, the CPU 11 receives an input of data to be embedded in a two-dimensional code from the user via the operation unit 12 (step S41). Then, the CPU 11 accepts a selection input of any one of the registration numbers 61 of the encryption key table 60 stored in the flash memory 17 from the user via the operation unit 12 (step S42).

  Then, the CPU 11 reads the encryption key 62 corresponding to the registration number 61 selected and input in step S42 from the encryption key table 60 (step S43). Then, the CPU 11 encrypts the data input in step S41 using the encryption key read in step S43 and creates encrypted data (step S44).

  Then, the CPU 11 creates two-dimensional code image data including the encrypted data created in step S44 (step S45). For example, as shown in FIG. 10, the address data of the user is input in step S41, the address data is encrypted in step S43, and the two-dimensional code P22 including the address data encrypted in step S45 is stored. Image data is created.

  Then, the CPU 11 uses the image data of the two-dimensional code created in step S44 to create a slip by printing the two-dimensional code on a sheet together with the signature field by the printing unit 20 (step S46). For example, as shown in FIG. 10, a signature field P21 and a two-dimensional code P22 including encrypted address data are printed on a sheet to create a slip P2.

  Then, the CPU 11 determines whether or not to end the two-dimensional code printing process according to the presence / absence of an instruction input to end the two-dimensional code printing process via the operation unit 12 (step S47). If the two-dimensional code printing process is not terminated (step S47; NO), the process proceeds to step S41. When the two-dimensional code printing process ends (step S47; YES), the two-dimensional code printing process ends.

  Next, a two-dimensional code reading process executed by the reading device 30 will be described with reference to FIGS. 11 and 12. The two-dimensional code reading process is a process of reading and decoding the two-dimensional code of the slip created by the two-dimensional code printing process. Assume that a data acquisition requester who requests data acquisition has previously written a signature in the signature column of a slip created by the two-dimensional code printing process using the reading device 30.

  In the reading device 30, for example, the CPU 31 is read from the ROM 35 and appropriately expanded in the RAM 33 when triggered by the input of the execution instruction for the two-dimensional code reading process from the data acquisition requester via the operation unit 32. The two-dimensional code reading process is executed in cooperation with the two-dimensional code reading program 352.

  First, the CPU 31 scans the signature and two-dimensional code of the slip by the scanner unit 38 in response to the pressing input of the trigger key 32A of the operation unit 32, acquires the image data, and stores it in the RAM 33 (step S51). . For example, as shown in FIG. 12, the signature and the two-dimensional code P22 in the signature column P21 of the slip P2 are scanned by the scanner unit 38 of the reading device 30, and their image data is acquired.

  Then, the CPU 31 decodes the image data of the two-dimensional code acquired in step S51, and acquires encrypted data included in the two-dimensional code (step S52). For example, as shown in FIG. 12, the image data of the two-dimensional code P22 is decoded, and the encrypted data is acquired.

  Then, the CPU 31 determines whether or not the decoding is successful in step S52 (step S53). When the decoding is successful (step S53; YES), the CPU 31 identifies a sign from the sign image of the sign image data acquired in step S51 (step S54). In step S54, for example, feature data is acquired from a signature image.

  Then, the CPU 31 collates the signature identified in step S54 with the signatures 52 of all records in the signature / key table 50 (step S55). In step S55, for example, signature verification is performed by comparing the signature feature data acquired in step S54 with the signature 52 feature data. For example, as shown in FIG. 12, the signature in the signature column P21 is identified, and the feature data is collated with the feature data of the signature 52 in the signature / key table 50.

  Then, the CPU 31 determines whether or not there is a sign 52 of the sign / key table 50 that matches the sign acquired in step S51 based on the sign collation result in step S55 (step S56).

  If there is a matching sign 52 (step S56; YES), the CPU 31 reads and acquires the decryption key 54 corresponding to the matching sign 52 (step S57). Then, the CPU 31 decrypts (decrypts) the encrypted data acquired in step S52 using the decryption key acquired in step S57, and acquires the decrypted data (step S58). For example, as shown in FIG. 12, the encrypted data obtained by decoding the two-dimensional code P22 is decrypted, and address data is obtained as decrypted data.

  Then, the CPU 31 displays the decoded data acquired in step S58 on the display unit 34 (step S59), and ends the two-dimensional code reading process.

  If the decoding is not successful (step S53; NO), or if there is no matching sign 52 (step S56; NO), the CPU 31 determines whether or not there is an instruction to interrupt the two-dimensional code reading process via the operation unit 32. Accordingly, it is determined whether or not the two-dimensional code reading process is interrupted (step S60). If not interrupted (step S60; NO), the process proceeds to step S51. When interrupting (step S60; YES), the CPU 31 displays on the display unit 34 that the decryption of the encrypted data included in the two-dimensional code has failed (step S61), and ends the two-dimensional code reading process.

  As described above, according to the present embodiment, the slip printing apparatus 10 receives input of data to be embedded in a two-dimensional code and selection input of a registration number 61 corresponding to a person who is permitted to acquire the data. Then, the slip printing apparatus 10 reads the encryption key 62 corresponding to the registration number 61 selected and input from the encryption key table 60, encrypts the input data with the encryption key 62, and stores the two-dimensional code. The voucher is created by converting the image data into image data and causing the printing unit 20 to print the image data of the two-dimensional code. The reading device 30 scans the two-dimensional code printed on the slip and the handwritten signature entered on the slip with the scanner unit 38 to acquire image data, and the feature data of the image data of the acquired handwritten signature, The feature data of the signature 52 of the signature key table 50 is collated. The reading device 30 reads the decryption key 54 corresponding to the handwritten signature that has been successfully verified, decodes the two-dimensional code of the acquired image data to acquire encrypted data, and reads the read decryption key 54 The data is decoded and displayed on the display unit 34. For this reason, only an appropriate reading device 30 that stores the sign / key table 50 can easily acquire and embed data embedded in the two-dimensional code by an authorized person who has permitted the acquisition.

  Further, the reading device 30 creates an encryption key and a decryption key in correspondence with the handwritten signature scanned by the scanner unit 38, and associates with the handwritten signature image data (signature 52) and the registration number 51 in the sign / key table. The registration number and the encryption key are transmitted to the slip printing apparatus 10. The slip printing apparatus 10 receives the registration number and the encryption key transmitted from the reading apparatus 30 and stores them in the encryption key table 60 for registration. Therefore, the sign / key table 50 can be appropriately and easily created and stored in the reading device 30, and the slip printing apparatus 10 can appropriately and easily acquire and store the encryption key table 60.

  The reading device 30 also stores a sign / key table 50 including a sign 52 that is image data of a handwritten signature. Therefore, the signature can be easily verified by comparing the feature data obtained from the image data of the handwritten signature with the feature data obtained from the signature 52.

  Further, the reading device 30 displays the decoded data decoded from the two-dimensional code on the display unit 34. Therefore, a person who is permitted to acquire data embedded in the two-dimensional code can easily acquire the decoded data visually.

  One specific example of the above embodiment will be described. This example is an example in which the slip processing system 1 of the above embodiment is applied to delivery of a package.

  A case where a delivery company delivers a customer's package to a delivery destination will be described. It is assumed that a collection point and a delivery place of a delivery company are set up in a certain area. The collection point is a store that collects packages from customers. A plurality of delivery offices are provided for each delivery area, and each is a store that delivers packages to the installed delivery area. A person in charge of collection is arranged at the collection point. Each delivery place has at least one delivery person. The person in charge of delivery also serves as the driver of the delivery vehicle. In this way, it is assumed that there are a plurality of persons in charge of delivery. In addition, it is assumed that a plurality of reading devices 30 are prepared for all persons in charge of delivery.

  In this embodiment, a delivery person who permits delivery for each package is designated, and only the delivery person designated for a given package delivers the package.

  First, the process before collection will be described. A delivery person in all delivery areas writes a handwritten signature on an arbitrary sheet. Then, the administrator collects all signed sheets, causes one reading device 30 to execute pre-registration processing, registers the signatures of all signed sheets, and enters the encryption key and registration number into a slip. It is transmitted to the printing apparatus 10. The registration number may be identification information such as a person in charge name for identifying a person in charge of delivery and a person in charge code.

  The slip printing apparatus 10 receives and stores the encryption key and the registration number by executing the encryption key table update process. In the flash memory 37 of one reading device 30, a sign / key table 50 having records for all persons in charge of delivery is created and stored. The flash memory 17 of the slip printing apparatus 10 stores an encryption key table 60 having records for all delivery personnel.

  Then, the administrator transfers the sign / key tables 50 for all delivery persons stored in one reading device 30 to all the remaining reading devices 30 and stores them in the flash memory 37. These readers 30 are delivered to all delivery personnel. The slip printing apparatus 10 is handed over to the person in charge of collection.

  Next, processing in collection and slip creation will be described. At the collection point, the collection person receives the package from the customer. Then, the person in charge of collection collects the delivery route and the name of the person in charge of delivery from the delivery destination designated by the customer. Then, the person in charge of collection causes the slip printing apparatus 10 to execute the two-dimensional code printing process, and inputs data of a message (notes, business communication, etc.) addressed to the person in charge of delivery corresponding to step S41. In response to step S42, the person in charge of collection selects and inputs the registration number 61 corresponding to the determined delivery person in charge from the encryption key table 60.

  Then, in response to steps S43 to S46, the slip printing apparatus 10 creates a slip by printing the two-dimensional code including the encrypted data of the target delivery person and the signature field on the paper. The person in charge of collecting affixes the printed slip on the package.

  Next, processing in delivery will be described. The package with the slip attached is delivered from the collection place to the delivery place by a delivery vehicle by a delivery driver between the collection place and the delivery place. Then, at the delivery office, the delivery person enters a handwritten signature in the signature column of the slip attached to the delivered package. Then, the person in charge of delivery causes the reading device 30 owned by the delivery person to execute the two-dimensional code reading process. The reading device 30 scans the slip attached to the package. If the signed delivery person is a delivery person for whom data acquisition is permitted (delivery permission), the signature verification is successful and the decoded data is displayed on the display unit 34. The target delivery person confirms the message addressed to the delivery person, which is decryption data, and delivers the package to the delivery destination with a delivery vehicle. If the signed delivery person is not the target delivery person, the message addressed to the delivery person cannot be seen and delivery cannot be performed.

  According to this embodiment, in delivery of a package, a message addressed to a delivery person as data embedded in a two-dimensional code is sent only by an appropriate reader 30 in which the sign / key table 50 is stored. Can be easily acquired.

  Another specific example of the above embodiment will be described. This example is an example in which the slip processing system 1 of the above-described embodiment is applied to payment of money such as prize money.

  Explain the case where a prize supplier pays a customer who has won a prize. The prize trader has a slip processing system 1. Money is exchanged at financial institutions such as banks. This financial institution has a reading device 30.

  First, the process before the prize draw will be described. A customer who has applied for a prize will write a handwritten signature on a form prepared by the company and send it to the company. The administrator of the prize trader receives the signed paper, causes the reading device 30 to execute pre-registration processing, registers the signatures of all the signed paper, and stores the encryption key and registration number in the slip printing apparatus 10. Send it. The registration number may be identification information such as a name for identifying a customer, a customer code, or the like.

  The slip printing apparatus 10 receives and stores the encryption key and the registration number by executing the encryption key table update process. A sign / key table 50 having records for all customers is created and stored in the flash memory 37 of the reader 30 of the prize winner. The flash memory 17 of the slip printing apparatus 10 stores an encryption key table 60 having records for all customers.

  The administrator of the prize trader transfers the signature / key table 50 for all customers stored in the reader 30 of the prize winner to the reader 30 of the financial institution and stores it in the flash memory 37. This reader 30 is handed over to the financial institution.

  Next, processing in lottery and voucher creation will be described. The manager of the sweepstakes company draws the winners of the sweepstakes from all customers. Then, the manager of the prize supplier causes the slip printing apparatus 10 to execute the two-dimensional code printing process, and inputs message data such as the prize money of the prize in accordance with step S41. Then, the manager of the prize trader selects and inputs the registration number 61 corresponding to the selected customer from the encryption key table 60 corresponding to step S42.

  Then, in response to steps S43 to S46, the slip printing apparatus 10 creates a slip by printing a two-dimensional code including the encrypted data of the winning customer and the signature field on the postcard by the printing unit 20. Then, the administrator of the sweepstaker sends the printed slip postcard to the winning customer.

  Next, a process for cashing money will be described. The customer receives the postcard sent from the prize winner and brings the postcard to the financial institution. Then, at the financial institution, the customer who brought the postcard enters a handwritten signature in the sign field of the postcard. The person in charge of the financial institution causes the reader 30 of the financial institution to execute a two-dimensional code reading process. If the customer who signed the postcard is a winning customer, the signature verification is successful and the decrypted data is displayed on the display unit 34. The person in charge of the reception visually confirms a message such as the winning amount as decryption data, and hands over the money of the winning amount corresponding to the decryption data to the signed customer. If the signing customer is not the winning customer, the postcard is illegally used as a voucher and money cannot be received.

  In addition, as a payment of money other than the prize money, the slip processing system 1 may be applied to payment of other money such as a refund or benefit to the target residents by the local government.

  As described above, according to the present embodiment, in the payment of money, a message such as the payment amount as data embedded in the two-dimensional code is sent to the appropriate customer by only the appropriate reading device 30 in which the sign / key table 50 is stored. The person in charge of reception can easily obtain it.

  In addition, the description in the said embodiment and Example is an example of the slip processing system which concerns on this invention, and is not limited to this.

  In the above-described embodiment and examples, the reading device 30 is configured to store the sign / key table 50 including the sign 52 which is image data as the sign data of the handwritten signature in the flash memory 37, but the present invention is not limited thereto. It is not something. For example, the reading device 30 may be configured to store a sign / key table 50 including a sign 52 that is feature amount data as sign data of a handwritten signature in the flash memory 37. Accordingly, in step S14 of the pre-registration process, the feature data of the signature 52 is used as it is for collation. In step S17, the feature data of the handwritten signature acquired in step S13 is stored in the sign / key table 50 as the signature 52. Stored. In step S55 of the two-dimensional code reading process, the feature data of the sign 52 is used as it is for collation. Therefore, by comparing the feature data obtained from the image data of the handwritten signature with the signature 52, the signature can be easily verified, and the capacity of the signature / key table 50 can be reduced.

  Moreover, in the said embodiment and Example, although the reader 30 was set as the structure which displays decoding data on the display part 34, it is not limited to this. For example, the reading device 30 may include an output unit that outputs decoded data by voice output, print output, transmission to an external device, or the like.

  Moreover, in the said embodiment and Example, the slip printing apparatus 10 is good also as a structure which comprises a scanner part and performs a pre-registration process using the said scanner. By this pre-registration process, the sign / key table 50 and the encryption key table 60 are stored in the flash memory 17. Alternatively, only the sign / key table 50 may be stored in the flash memory 17, and the registration number 51 and the encryption key 53 of the sign / key table 50 may be used in the two-dimensional code printing process.

  In addition, it goes without saying that the detailed configuration and detailed operation of each component of the slip processing system in the above-described embodiment and examples can be appropriately changed without departing from the spirit of the present invention.
