On the other hand, the slave financial printer 16B is the same as the representative financial printer 16A in terms of other structures and functions, and has the function of issuing receipts and storing financial information under the control of the host computer 15 similarly to the representative financial printer 16A.

<description of financial information>

Next, written receipt data 54 (receipt information) stored in the EJ memory 31 and daily sales data 53 (sales information) stored in the accounting memory 50 will be described. As stated above, this data amounts to financial information.

The written receipt data 54 is data indicating information recorded on a receipt issued by the financial printer 16, and is predetermined as data to be stored. For example, information indicating the item, information indicating the unit price of the item, information indicating the number of items purchased, information indicating the payment for each item purchased, and In the case of information indicating the total purchase price of all products, and when data indicating such information is predetermined as data to be stored, the data indicating such information corresponds to writing in the receipt data 54 .

As mentioned above, in this embodiment, when the receipt is issued by the financial printer 16, the control command is generated by the host computer 15, and the control command is output to the main control unit 25, and then the control command is output from the main control unit 25 to the main control unit 25. Printer control section 45 . At this time, the main control unit 25 extracts the information that should be stored as the write-in receipt data 54 from the control command, and uses the extracted information as the write-in receipt data 54 to control the first memory control unit 32 to store in the EJ in memory 31.

In the present embodiment, the written receipt data 54 includes the subtotal amount T1, the total amount T2, and the payment amount T3 in the receipt. That is, as described above, the subtotal amount T1, the total amount T2, and the payment amount T3 are recorded in the receipt issued by the financial printer 16 according to this embodiment (see FIG. 3 ), but the main control unit 25 At least these three kinds of information are extracted from the control command and stored in the EJ memory 31 as write receipt data 54 .

Here, when the main control unit 25 writes the write receipt data 54 into the EJ memory 31 , it acquires data indicating the current date and time (year, month, day+time) from the RTC 30 . Based on the acquired data, the main control unit 25 generates EJ writing date and time data 55 (date and time information) representing the date and time, and associates the writing receipt data 54 with the EJ writing date and time data 55. write. That is, each write receipt data 54 is stored in the EJ memory 31 in association with the EJ write date and time data 55 , which is data indicating the date and time written in the EJ memory 31 .

Furthermore, when writing the write receipt data 54, the main control unit 25 calculates a hash value based on a predetermined hash function (Hash Function) from the write receipt data 54, and converts the calculated hash value to Encryption is performed with a private key specific to the financial printer 16 to generate an EJ digital signature 56 (additional information) as a digital signature, and the written receipt data 54 is written in association with the EJ digital signature 56 . That is, each writing receipt data 54 is stored in the EJ memory 31 in association with the EJ digital signature 56 generated based on each data.

In addition, one reason for storing the date and time data 55 written in EJ in association with the written receipt data 54 is that it is obligatory to do so according to national laws and regulations.

The daily sales data 53 (sales information) is the total sales of "one day" obtained by calculating the receipts issued by the accounting printer 16 . The term "one day" in the present embodiment refers to the period from opening to closing in a store to which the store system 10 is applied. The host computer 15 controls the financial printer 16 to issue a receipt for each settlement at the cash register L, and accumulates and stores the turnover amount (=payment amount T3 in the receipt) for each settlement. Moreover, the host computer 15 calculates the "one day" associated with the corresponding financial printer 16 based on the accumulatively stored turnover amount for each account settlement at a prescribed timing after the store closes (for example, when the person in charge has an instruction, when the prescribed timing is reached). " in the total turnover. The host computer 15 generates daily sales data 53 based on the calculated total sales, and outputs the generated daily sales data 53 to the main control unit 25 . When the daily sales data 53 is input, the main control unit 25 controls the second memory control unit 51 and writes the daily sales data 53 in the accounting memory 50 .

Here, the main control unit 25 outputs data indicating the current date and time to the RTC 30 when writing the daily turnover data 53 into the accounting memory 50 , and acquires the date and time when writing is performed based on the data. The main control unit 25 writes the date and time in the financial memory 50 in a state where the date and time data 52 (date and time information) representing the acquired date and time (date and time information) are associated with the daily turnover data 53 . Calculate turnover data53. That is, each daily turnover data 53 is stored in the accounting memory 50 in association with the accounting writing date and time data 52 , which is data indicating the date and time written in the accounting memory 50 .

Furthermore, when the main control unit 25 writes the daily turnover data 53, it generates a financial digital signature 58 (additional information) as a digital signature based on the daily turnover data 53, and writes the daily turnover data 53 and the financial digital signature. The signature 58 is written accordingly. That is, each daily turnover data 53 is stored in the financial memory 50 in association with the financial digital signature 58 generated based on each data.

In this example, the hash function and private key used to generate the financial digital signature 58 are the same as the hash function and private key used to generate the EJ digital signature 56, but may be different from each other.

In this way, in the present embodiment, the date and time data 52 written in finance and the daily turnover data 53 are stored in association with each other, because it is obligatory to do so according to the laws and regulations of the country.

However, in the prior art, when a responsible person such as the government acquires financial information stored in each financial printer 16 (in this example, written receipt data 54 and/or daily turnover data 53), Go to the store with the above-mentioned financial data reading device 40, the financial data reading device 40 and the financial printer 16 are connected by a dedicated cable, and by the function of the dedicated software tool installed in the financial data reading device 40, Financial information is extracted from the financial printer 16 . However, the method in the prior art requires labor and is very cumbersome, and there is a need to improve efficiency.

Furthermore, as described above, since financial information is sometimes used as information for grasping the actual status of transactions, accuracy is required, and when the content has been changed due to falsification, it is required to be able to detect this. In addition, by introducing a structure for detecting tampering, it can also become a force for suppressing tampering.

Based on the above, the server device 11 and the financial printer 16 according to this embodiment perform the following processes.

First, before describing in detail the operations of the server device 11 , the representative financial printer 16A, and the slave financial printer 16B, the operations of these devices will be briefly described.

FIG. 5 is a schematic diagram briefly showing the basic operations of the server device 11, the representative financial printer 16A, and the slave financial printer 16B. Referring to FIG. 5 , a flow when the server device 11 acquires financial information from one slave financial printer 16B constituting the store system 10 will be described.

The server device 11 requests the representative financial printer 16A to transmit financial information of a specific subordinate financial printer 16B (step SX1). The representative fiscal printer 16A determines the subordinate fiscal printer 16B that should transmit the financial information based on the request, and requests the specified subordinate fiscal printer 16B to transmit the financial information (step SX2 ). Hereinafter, the slave financial printer 16B to which financial information should be transmitted is referred to as a "target printer".

The target printer associates financial information with a digital signature generated based on the financial information (hereinafter referred to as “subordinate digital signature”), stores them in association, and transmits the financial information and the combination of the subordinate digital signature to the representative financial printer 16A. (step SX3). The subordinate digital signature is a digital signature generated based on a private key unique to the target printer and a hash function.

Public keys corresponding to private keys of all subordinate fiscal printers 16B, and hash functions are managed on behalf of the fiscal printer 16A. Then, when the representative financial printer 16A receives a combination of financial information and subordinate digital signatures (hereinafter referred to as "subordinate financial information group") from the target printer, it uses the public key of the target printer and a hash function to detect Presence or absence of falsification (step SX4). If tampering is detected, the representative fiscal printer 16A performs corresponding predetermined processing. On the other hand, if tampering is not detected by the representative financial printer 16A, a digital signature (representative Additional information. Hereinafter referred to as "representative digital signature".) (step SX5). Next, the representative financial printer 16A transmits a combination of the subordinate financial information group and the representative digital signature to the server device 11 (step SX6).

The server device 11 manages a public key (hereinafter referred to as a "representative public key") corresponding to a representative private key, and also manages a hash function used for generating a representative digital signature. Then, when the server device 11 receives a combination of the subordinate financial information group and the representative digital signature, it detects the presence or absence of falsification of the subordinate financial information group based on the representative digital signature (step SX7). In addition, the server device 11 checks the compatibility of the financial information of the target printer by a method described in detail later.

Next, the operations of the server device 11 , the representative financial printer 16A, and the subordinate financial printer 16B will be described in detail using the flowchart of FIG. 6 . In FIG. 6 , (A) shows the operation of the server device 11 , (B) shows the operation of the master financial printer 16A, and (C) shows the operation of the slave financial printer 16B, especially the target printer.

In the following description, the functions of the financial information acquisition unit 60a in the server device 11 and the information processing unit 25a in the financial printer 16 are realized by reading and executing a predetermined program by the CPU, etc., with the assistance of hardware and software. .

Here, as described with reference to FIG. 2 , in this embodiment, the representative financial printer 16A is provided with a GPRS communication module 34 and can be connected to the server device 11 via the telephone network 12 . Then, as will be described below, in the present embodiment, a configuration that enables easy acquisition of financial information is realized after making full use of this new configuration so that falsification can be reliably detected.

In this way, the representative financial printer 16A that stores financial information is equipped with a GPRS communication module 34 and can be connected to the server device 11 via the telephone network 12, which is a new structure that the existing device does not have. Furthermore, the configuration of connecting the slave financial printer 16B, which does not have a communication function with the server device 11, to the representative financial printer 16A via the local area network N is also a new configuration that does not exist in conventional devices and systems.

With reference to Fig. 6, at first the financial information acquisition part 60a of the server side control part 60 of server device 11, generate a kind of mail, this mail request sends the writing receipt data 54 of certain specific subordinate financial printer 16B and the daily turnover Data 53, that is, write receipt data 54 related to receipts sent within a certain specific period, and daily calculation turnover data 53 (step SA1) involved in this specific period. This mail can use SMS (short message service) to send mail.

In addition, in this example, a "specific period" is a specific date (for example, "2012/1/1" etc.).

FIG. 7 is a diagram schematically showing the contents of the mail generated in step SA1.

In the mail, at least the following content is described according to the predetermined format: (1) clearly show the type of financial information that you want to obtain (in this example, write in the receipt data 54, the daily turnover data 53; one or both), (2) information clearly showing a specific period, (3) the address to which the financial information should be sent (in this example, the telephone number of the server device 11), and (4) the confirmation request Information of the financial printer 16 (target printer) that transmits financial information. In addition, the fiscal printer 16 to which transmission of financial information is requested may be the representative fiscal printer 16A, but for convenience of explanation, it is referred to as the subordinate fiscal printer 16B.

In the example of FIG. 6, in the mail, according to the prescribed format, information indicating (1) the type of financial information is described in the prescribed area on the first line, and information indicating a specific period is described (2) in the prescribed area on the second line. For the information, information indicating the destination of the financial information is described in a predetermined area on the third line, and information identifying the financial printer 16 is described in a predetermined area on the fourth line. In addition, in this example, the information identifying the fiscal printer 16 refers to an identification number uniquely assigned to the fiscal printer 16 . The identification number of each financial printer 16 is managed by the server device 11 and the representative financial printer 16A. The information specifying the fiscal printer 16 may be arbitrary information, for example, may be information clearly showing the cash register L where the fiscal printer 16 is installed.

Although detailed description is omitted, the server device 11 is configured to provide a user interface for inputting to the user of the server device 11: (1) the type of financial information to be acquired, (2) a specific period , and (3) the identification number of the fiscal printer 16. When the user inputs through the interface: (1) the type of financial information, (2) a specific period, and (3) the identification number of the financial printer 16, once the input is confirmed, the financial information acquisition unit 60a automatically generates an email in accordance with the format.

When generating an e-mail, the financial information acquisition unit 60a controls the server-side GPRS communication module 64, and sends the generated e-mail to the representative financial printer 16A (step SA2). The server device 11 manages the telephone number representing the financial printer 16A.

Emails using SMS are sent to the fiscal printer 16 promptly and proactively because they are push-type electronic mails.

Once the mail is received from the server device 11 (step SB1), the information processing unit 25a of the main control unit 25 representing the financial printer 16A analyzes the received mail, and acquires the type of financial information to be sent to the server device 11, A specific period and the identification number of the slave financial printer 16B (target printer) to which financial information should be transmitted (step SB2). In this example, as shown in FIG. 7, it is assumed that the type of financial information to be transmitted is written receipt data 54 and daily sales data 53, and the specific period is "2012/1/1". In addition, a dedicated program is installed in the financial printer 16 with a function of analyzing mail described in a predetermined format and acquiring the type of financial information to be sent, a specific period, and the identification number of the financial printer 16 .

Next, the information processing unit 25a communicates with the target printer corresponding to the acquired identification number through the local area network N according to a predetermined protocol, and requests to send the written information related to the receipt issued during the specific period, that is, "2012/1/1". Receipt data 54 and daily sales data 53 related to "2012/1/1" which is a specific period (step SB3).

In response to this request, the target printer accesses its own EJ memory 31, writes date and time data 55 using EJ, and acquires written receipt data 54 related to receipts issued during a specific period, that is, "2012/1/1", and the corresponding All EJs are digitally signed 56 (step SC1).

Furthermore, the target printer accesses its own financial storage 50, and uses the financial write date and time data 52 to obtain the daily turnover data 53 and the corresponding financial digital signature 58 of a specific period, that is, "2012/1/1" (step SC2).

Next, the target printer sends all the data acquired in step SC1 and step SC2 to the representative financial printer 16A via the local area network N according to a predetermined protocol (step SC3).

In this way, in this embodiment, the GPRS communication module 34 is installed in the representative financial printer 16A, and the server device 11 requests transmission of financial information from a specific financial printer 16 by mail using SMS. Therefore, a request for transmission of financial information from the server device 11 to the representative financial printer 16A can be performed by using a simple method using an existing system such as mail using the telephone network 12 .

Furthermore, with the above configuration, the following effects are achieved.

That is, since the email using the SMS is a push email, it is immediately and proactively sent to the representative financial printer 16A. Therefore, after the user of the server device 11 instructs a transmission request of financial information, the transmission request is immediately and compulsorily notified to the representative financial printer 16A, and the processing for transmission of financial information is promptly executed accordingly, and the financial information is processed. sent. Therefore, when acquiring financial information, it is possible to acquire financial information unexpectedly before the representative financial printer 16A and the subordinate financial printer 16B perform some kind of processing such as fraudulent concealment by the shop owner. In this way, fraudulent acts using financial information can be found efficiently and quickly.

In addition, when the information processing unit 25a representing the financial printer 16A receives the written receipt data 54 as financial information and the daily turnover data 53 from the target printer (step SB4), it detects that there is a digital signature corresponding to these data. No tampering (step SB5). As described above, since the representative fiscal printer 16A manages the hash functions of all subordinate fiscal printers 16B connected via the local area network N and the public keys corresponding to the keys, it is possible to detect No tampering.

Next, the information processing part 25a discriminates whether tampering was detected in step SB5 (step SB6), and when detected (step SB6: Yes), it performs a corresponding process (step SB7). Corresponding processing means, for example, notifying the server device 11 or the like of detection of tampering, and reporting detection of tampering to a person who manages the server device 11 .

In this way, the configuration of the present embodiment is such that when the financial information stored in the slave financial printer 16B is falsified, or the financial information is falsified during transmission from the slave financial printer 16B to the representative financial printer 16A, it is possible to These conditions are detected exactly. In addition, this configuration becomes a force for suppressing tampering.

On the other hand, when tampering has not been detected (step SB6: No), the information processing unit 25a based on all the data received from the target printer, that is, "write receipt data 54 and EJ digital signature 56, and daily business Amount data 53 and financial digital signature 58" (hereinafter referred to as "all subordinate data"), using the unique representative private key and hash function managed by itself to generate a representative digital signature (step SB8). Next, the information processing unit 25a transmits a combination of all the dependent data and the representative digital signature to the server device 11 (step SB9).

When the combination of all the subordinate data and the representative digital signature is received (step SA3), the financial information acquisition unit 60a of the server device 11 uses the representative public key managed by itself and the hash function based on the representative digital signature to detect whether there is a pair Tampering of all slave data (step SA4). When falsification is detected, the financial information acquisition unit 60a controls the server-side display unit 63 to display on the display panel that the financial information may be falsified. In this way, the user of the server device 11 can quickly and easily recognize the possibility of falsification of financial information.

Here, it is assumed that the server device 11 and the financial printer 16 are configured to be communicable with each other, and that the financial printer 16 is configured to transmit financial information and a digital signature generated using a unique private key through communication. In this case, the server device 11 needs to manage the public key corresponding to the private key of each fiscal printer 16 . Furthermore, the server device 11 needs to manage the telephone numbers of the respective financial printers 16 and to individually request the transmission of financial information to each financial printer 16 . On the other hand, in this embodiment, with the above-mentioned configuration, the private key and the telephone number to be managed need only be information related to the representative financial printer 16A.

Next, the financial information acquisition unit 60a executes a compatibility checking process (step SA5).

FIG. 8 is a flowchart showing the operation of the server device 11 during the matching processing.

In the consistency verification process, first, the financial information acquisition unit 60a checks the consistency between the subtotal amount T1 and the total amount T2 based on the written receipt data 54 included in all the dependent data (step SD1).

Specifically, in one written receipt data 54, the total of the subtotal amount T1 and the total amount of money T2 must match unless some kind of falsification is performed. On this basis, the financial information acquisition unit 60a extracts the subtotal amount T1 and the total amount T2 from one written receipt data 54, and compares the amount obtained by summing up the subtotal amount T1 with the total amount T2, and if both If they match, it is judged as matching, and if they do not match, it is judged as non-matching. Whether or not matching is determined may be performed for all written receipt data 54 or for some of them.

Next, the financial information acquisition unit 60a determines whether or not it is determined that there is no compatibility in step SD1 (step SD2), and if it is determined that there is no compatibility (step SD2: Yes), it controls the server side display unit 63 to display The panel display indicates that the financial information, especially the written receipt data 54, may be falsified (step SD3). In this way, the user of the server device 11 can quickly and easily recognize that there is a possibility of falsification of the written receipt data 54 . In addition, when displaying, it may be displayed why there is no match between the subtotal amount T1 and the total amount T2 written in the receipt data 54 .

On the other hand, when it is determined that there is a match (step SD2: No), the financial information acquisition unit 60a checks the written receipt data 54 and the daily sales data 53 based on the written receipt data 54 and the daily sales data 53. Matching between amount data 53 (step SD4).

Specifically, as long as there is no tampering, the total of the payment amount T3 in all receipts issued during a certain period, and the total turnover in the settlements performed with the issuance of receipts involved in the specified period must be consistent. On this basis, the financial information acquisition unit 60a extracts the payment amount T3 from all the written receipt data 54, and compares the amount obtained by summing up the payment amount T3 with the total turnover indicated by the daily turnover data 53. If If the two match, it is determined that there is matching, and if they do not match, it is determined that there is no matching.

Next, the financial information acquisition unit 60a judges whether it is determined that there is no matching in step SD4 (step SD5), and if it is judged that there is no matching (step SD5: Yes), the process is transferred to step SD3, and the server side The display unit 63 performs control to display on the display panel that the financial information, especially the written receipt data 54 or the daily turnover data 53, or both of them may have been tampered with. In this way, the user of the server device 11 can quickly and easily recognize the possibility of tampering. In addition, when displaying, it is also possible to display why there is no match.

On the other hand, when it is judged that there is matching (step SD5: No), the financial information acquisition part 60a controls the server side display part 63, and displays on the display panel that the falsification of the financial information has not been detected ( Step SD6).

In this way, in this embodiment, the financial information acquisition unit 60a attempts to detect the presence or absence of falsification from various aspects using the characteristics of the information recorded in the received written receipt data 54 and daily sales data 53 . Therefore, tampering can be detected more accurately, and this in turn becomes a force for strongly suppressing tampering.
