JP 2013-51577 A

Recently, even in a ticket vending machine that issues a ticket according to ticket information input by a user, a transaction amount related to the ticket issuance is settled with a credit card.
At the time of payment with a credit card, in order to ensure security against counterfeit cards and impersonation, the user is asked to enter an authentication code (so-called PIN number) to confirm the identity of the cardholder (user and cardholder) Check if they match. A general ticket vending machine that can settle a transaction amount with a credit card includes a PIN pad. The user inputs an authentication code by operating the numeric keypad of the PIN pad. In addition, when the user purchases a ticket using the voice guidance function of the ticket vending machine, the user inputs the ticket information by operating the numeric keypad of the PIN pad. In other words, the PIN pad is an input device used for inputting an authentication code and inputting ticket information.

And in the ticket vending machine which can settle the transaction amount concerning the ticket issuance with a credit card, the authentication code which the PIN pad outputs to the control unit (has a function for processing the transaction amount with the credit card) is output. There is a demand for ensuring security against leakage from a signal transmission path connecting the PIN pad and the control unit (extracted by a malicious third party).

Note that Patent Document 1 does not specifically disclose the handling of an authentication code used for identity verification of the card owner.
An object of the present invention is to provide a technique for improving security against leakage of an authentication code input by a user by operating a numeric keypad of a PIN pad.
In order to achieve the above object, the ticket vending machine of the present invention is configured as follows.

The ticket vending machine according to the present invention can settle a transaction amount of a ticket issued according to the input ticket information with a credit card. The credit card may be a contact IC card, a magnetic card, or a magnetic / IC card.
The card processing unit reads card data recorded on a credit card inserted into the main body. The PIN pad has a numeric keypad used for an input operation of ticket information and an input operation of an authentication code used for personal authentication at the time of payment with a credit card. That is, the PIN pad is used for inputting an authentication code and entering ticket information. The control unit uses the card data read by the card processing unit and the authentication code input in the PIN pad to settle the transaction amount for issuing the boarding ticket.

Then, the PIN pad encrypts the input authentication code and outputs it to the control unit.
Therefore, even if the authentication code output from the PIN pad to the control unit is extracted by a malicious third party from the signal transmission path connecting the PIN pad and the control unit, the extracted authentication code is encrypted. Therefore, it is possible to improve the security against the leakage of the authentication code.

The PIN pad is preferably configured to output the input ticket information to the control unit without encryption. If comprised in this way, the encryption process with respect to boarding ticket information which does not require especially security ensuring and a decoding process can be made unnecessary, and it can suppress that the processing load of a ticket vending machine main body becomes large.
In addition, the control unit may instruct the PIN pad whether information input by operating the numeric keypad (passage ticket information, authentication code, etc.) is output after being encrypted or without being encrypted. . With this configuration, it is possible to easily switch between encryption and non-encryption according to the necessity of ensuring security against information leaked from the PIN pad.

In addition, the control unit determines whether or not the credit card is a valid credit card that can be used for the settlement of the transaction amount using the card data read from the credit card inserted into the main body by the card processing unit, If it is determined that the credit card is not a valid credit card that can be used for the payment of the money amount, the authentication code may not be output to the PIN pad. With this configuration, it is possible not only to prevent the user from inputting the authentication code in vain, but also to prevent the authentication code encrypted by the PIN pad from being output to the control unit in vain.
(The invention's effect)
According to the present invention, it is possible to improve security against leakage of an authentication code input by a user by operating a numeric keypad of a PIN pad.

The banknote processing unit 7 has a banknote identification unit that identifies the denomination and authenticity of banknotes inserted by the user and banknotes released as change to the user.

Further, the ticket vending machine 1 is provided with a card insertion / release port 8a on the front surface of the main body. The user inserts into the card insertion / release port 8a a credit card used for settlement of the transaction amount related to the ticket issue or an SF card that can be used as a ticket. The card processing unit 8 takes in a card inserted into a card insertion / release port 8a provided on the front face of the ticket vending machine 1 into the main body, reads card data recorded on the card, and card data for the card. Is written (card data is updated). The card processing unit 8 outputs the card data read from the card inserted into the card insertion / release port 8a to the control unit 2 and the update card data input from the control unit 2 or the like to the card insertion / release port. Write to the card inserted in 8a. When the processing for the card inserted into the card insertion / discharge port 8a is completed, the card processing unit 8 discharges the card to the card insertion / discharge port 8a in order to return it to the user.

In this example, the SF card is described as a non-contact IC card having a wireless communication function. The credit card will be described as a contact IC card having an IC contact formed on the surface. The credit card may be an IC card having a magnetic stripe or an IC card in which no magnetic stripe is formed. The credit card may be a magnetic card that does not have an IC.

The card processing unit 8 has a wireless communication function for reading card data to the SF card and writing card data. The card processing unit 8 has an IC terminal that is brought into contact with an IC contact formed on the surface of the credit card, and a mechanism that makes the IC contact come in contact with and separates from the IC contact of the credit card. The card processing unit 8 reads the card data and writes the card data to the credit card in a state where the IC terminal is in contact with the IC contact of the credit card.

The PIN pad 9 operates in a plaintext mode or an encryption mode to be described later. The PIN pad 9 is an input device used for an input operation of ticket information of a ticket to be purchased, an input operation of an authentication code for identity verification when making a payment with a credit card, and the like.
The communication unit 10 controls communication with an authentication server that issues a credit payment authentication request via a network. The communication unit 10 also controls communication with station equipment such as an automatic ticket gate (not shown) and other ticket vending machines 1.

Here, the PIN pad 9 will be described in more detail. FIG. 3 is a block diagram showing the configuration of the main part of the PIN pad. The PIN pad 9 includes a control unit 21, a numeric keypad operation unit 22, and an input / output I / F 23.
The control unit 21 controls the operation of the PIN pad 9. The numeric keypad 22 has ten numeric keys (numeric keys corresponding to 0 to 9) and two symbol keys “*” and “#”. The PIN pad 9 notifies the control unit 21 of the pressed key. The input / output I / F 23 controls input / output with the control unit 2 of the ticket vending machine 1 main body. Further, each key of the numeric keypad operation unit 22 and the control unit 21 are electrically connected not by a cable but by a print pattern, and security against a signal being extracted between the numeric keypad operation unit 22 and the control unit 21. Is secured.

When the operation in the plain text mode is designated from the ticket vending machine 1 main body, the control unit 21 operates the PIN pad 9 in the plain text mode. Further, when the operation in the encryption mode is designated from the ticket vending machine 1 main body, the control unit 21 operates the PIN pad 9 in the encryption mode. In the plaintext mode, when any key of the numeric keypad 22 is operated, a key code corresponding to the key is output to the control unit 2. In the encryption mode, when any key of the numeric keypad 22 is operated, the operated keys are sequentially stored in a memory (not shown) of the control unit 21 and the control unit indicates that the key has been pressed. 2 is a mode to output to 2. In addition, when a specific key (“#” in this example) of the numeric keypad 22 is pressed, the encryption mode is a key sequence stored in the memory of the control unit 21 (this key sequence is the numeric keypad And the encrypted data is output to the control unit 2. The control unit 21 stores an encryption key used for encryption of the key string in the memory.

Next, the operation of the ticket vending machine 1 will be described. FIG. 4 is a flowchart showing the ticket issuing process in the ticket vending machine. In the control unit 2, the ticket vending machine 1 determines whether the user has selected the voice guidance mode or the normal mode (s1). In the voice guidance mode, in a voice guidance section (not shown), a guidance message for guiding an input operation related to purchase of a ticket is sent to the user, and the user inputs the ticket information using the PIN pad 9. This mode accepts and issues a ticket. The normal mode is a mode in which the display unit 3 controls the display screen on the display device 3a, and the operation unit 4 accepts an input operation of ticket information by the user and issues a ticket.

The control unit 2 determines that the voice guidance mode is selected, for example, when a voice guidance mode selection key (for example, “*” key) of the numeric keypad 22 of the PIN pad 9 is pressed. That is, the user can select the voice guidance mode by pressing the voice guidance mode selection key on the numeric keypad 22 of the PIN pad 9. In addition, the control unit 2 determines that the normal mode has been selected when the operation unit 4 detects the pressing position of the user on the touch panel 4a without pressing the voice guidance mode selection key of the numeric keypad operation unit 22 of the PIN pad 9. judge. That is, the user can select the normal mode by pressing the touch panel 4a pasted on the screen of the display 3a without operating the numeric keypad 22 of the PIN pad 9.

When the control unit 2 determines that the selected mode is the voice guidance mode, the voice guidance unit starts voice guidance (s2). At this time, the control unit 2 designates the plain text mode for the PIN pad 9. The control unit 2 may be configured to designate either the plaintext mode or the encryption mode to be described later on the PIN pad 9, or the type of information that accepts an input operation by the user (ticket information, authentication code, etc. ) May be output to the PIN pad 9, and the PIN pad 9 may select a plaintext mode or an encryption mode depending on the type of information.

The PIN pad 9 accepts an input operation of ticket information by the user (s3). The user presses a key on the numeric keypad 22 to input the ticket information. The PIN pad 9 outputs a key code corresponding to the key pressed by the user to the control unit 2. As described above, since the plain text mode is designated at this time, the PIN pad 9 does not encrypt the key code corresponding to the pressed key every time the user presses the key. And output to the control unit 2 (details of the operation of the PIN pad 9 in the plaintext mode will be described later).

If the control unit 2 determines that the selected mode is the normal mode, the operation unit 4 accepts an input operation of ticket information by the user (s4). The operation unit 4 outputs an input code corresponding to the pressed position of the user on the touch panel 4a to the control unit 2.
When the control unit 2 receives the ticket information of the ticket to be issued this time at s3 or s4, the settlement of the transaction amount relating to the ticket issuance is a credit settlement by a credit card, or a cash by money It is determined whether it is a settlement (s5). If the control unit 2 determines that it is a credit settlement, the card processing unit 8 accepts a credit card used for settlement of the transaction amount (s6). The card processing unit 8 receives a credit card inserted by the user into the card insertion / release port 8a. On the other hand, when it is determined that the control unit 2 is cash settlement, the coin processing unit 6 accepts the insertion of coins by the user, and the bill processing unit 7 accepts the insertion of bills by the user (s10).

It should be noted that the determination as to credit settlement or cash settlement may be made in accordance with the user's selection input operation. Moreover, the structure which determines with it being a credit card payment may be sufficient when the card processing unit 8 receives the credit card inserted in the card insertion / release port 8a. In this case, when the coin processing unit 6 receives a coin inserted into the coin insertion slot 6a, or when the banknote processing unit 7 receives a banknote inserted into the banknote insertion slot 7a, it is determined to be a cash settlement. That's fine.

The control unit 2 transports the credit card received in s6 to the card data reading position, brings the IC terminal into contact with the IC contact of the credit card, reads the card data, and instructs the PIN pad 9 on the encryption mode. To do. Details of the operation of the PIN pad 9 in the encryption mode will be described later. The PIN pad 9 accepts an input operation of an authentication code (so-called password) by the user at the numeric keypad 22 (s7). The authentication code is a number of multiple digits (for example, 4 digits). The user presses the numeric key of the numeric keypad 22 in order from the upper digit and inputs the authentication code. The PIN pad 9 generates encrypted data obtained by encrypting key strings arranged in the order in which the numeric keys are pressed in the control unit 21, and outputs the encrypted data to the control unit 2.

In the settlement unit 2a, the control unit 2 performs a settlement process (credit settlement) in which the transaction amount of the ticket issued with the current ticket information is settled with the credit card accepted in s6 (s8). In s8, transaction authentication may be performed by offline authentication or online authentication. In the off-line authentication, whether the credit card accepted by the card processing unit 8 is within the validity period, the authentication code recorded on the IC of the credit card and the authentication code input on the PIN pad 9 this time match. Authenticates whether or not the transaction is possible depending on whether or not In the online authentication, the communication unit 10 transmits transaction authentication data including the card number of the credit card received by the card processing unit 8, the input authentication code, the current transaction amount, etc. to the authentication server. Receives an authentication result indicating whether or not the transaction is possible. The authentication server determines whether the card is valid / invalid (in this case, not only whether it is within the validity period but also whether it is an invalid card registered in the negative file), and the authentication code is appropriate. Whether or not the transaction is possible is verified by whether or not the transaction is within the credit limit range.

When the settlement unit 2a settles the transaction amount for ticketing with a credit card, the card processing unit 8 releases the credit card accepted this time to the card insertion / release port 8a and the ticketing unit 5 accepts this time A ticketing process for releasing the boarding ticket corresponding to the information to the ticketing slot 5a is performed (s9), and the process returns to s1.
When the settlement unit 2a fails to settle the transaction amount for issuing the ticket using a credit card, the card processing unit 8 releases the accepted credit card to the card insertion / release port 8a, but the ticketing unit 5 Do not issue a ticket according to the ticket information received this time. In addition, when the settlement unit 2a cannot settle the transaction amount for issuing a ticket with a credit card, the present ticketing process may be shifted to the process after s10 described later. The control unit 2 determines whether the credit card accepted by the card processing unit 8 is within the expiration date before accepting the input of the authentication code. If the credit card is not within the expiration date, the PIN pad 9 The authentication code input may not be accepted.

If the control unit 2 determines that the payment is a cash settlement, the total amount of money inserted at the coin insertion slot 6a and the banknote insertion slot 7a corresponds to the ticket information received at s3 or s4. Wait until the transaction amount exceeds (s10). The control unit 2 issues a ticket when the total amount of money inserted at the coin insertion slot 6a and the bill insertion slot 7a is equal to or greater than the transaction amount of the ticket corresponding to the ticket information received at s3 or s4. The transaction amount of the ticket is settled with cash (s11). When the transaction amount required for issuing the ticket is settled in cash, the coin processing unit 6 and the banknote processing unit 7 release the change as necessary, and the ticket issuing unit 5 responds to the ticket information received this time. The ticket issuing process for releasing the boarded ticket to the ticket opening 5a is performed (s12), and the process returns to s1.

As described above, the ticket vending machine 1 according to this example can perform settlement of the transaction amount related to the ticket issuing with a credit card or money.
Here, the operation in the plain text mode and the operation in the encryption mode of the PIN pad 9 will be described. FIG. 5 is a flowchart showing the operation of the plain text mode of the PIN pad. FIG. 6 is a flowchart showing the operation of the PIN pad encryption mode.

First, the operation in plain text mode will be described. When any key is operated (s21), the numeric keypad 22 notifies the controller 21 of the operated key (s22). The control unit 21 outputs a key code corresponding to the key notified from the numeric keypad operation unit 22 (the key operated this time) to the control unit 2 connected to the input / output I / F 23 (s23), and to s21 Return.

As described above, in the plain text mode, the PIN pad 9 does not encrypt the key code corresponding to the key operated at any time when any key of the numeric keypad operation unit 22 is operated. Output to.
Next, the operation in the encryption mode will be described. When any key is operated (s31), the numeric keypad 22 notifies the controller 21 of the operated key (s32). The control unit 21 determines whether or not the key notified from the numeric keypad operation unit 22 is a predetermined specific key (in this example, “#” key) (s33). This specific key is a key operated when the operator inputs completion of the input operation. For example, when the operator inputs a 4-digit number string 3648 on the PIN pad 9, the “3”, “6”, “4”, and “8” keys on the PIN pad 9 are sequentially operated, and then “#” is operated. To do.

When determining that the key is not a specific key in s33, the control unit 21 stores the key operated this time (that is, the key notified from the numeric keypad operation unit 22 in s22) in a memory (not shown) (s34). In s34, the control part 21 memorize | stores the key operated in the ten key operation part 22 of the PIN pad 9 in the operated order. Further, the control unit 21 outputs a key operation to the control unit 2 connected to the input / output I / F 23 (s35), and returns to s31.

The control unit 2 can determine how many digits have been input at that time by outputting that the key operation of the PIN pad 9 has been performed. Therefore, the control unit 2 can instruct the display unit 3 to display on the display 3a a screen on which the number of digits input by the operator can be confirmed, for example. This screen is a screen that displays, for example, the same number of “*” as the number of digits input by the operator.

In addition, the order of the processes concerning s34 and s35 may be the reverse order of the above.
When determining that the key is a specific key in s33, the control unit 21 encrypts the key string stored in the memory (the key stored in the order operated in s34) (s36). For example, when the operator inputs a 4-digit number string 3648, the key strings “3”, “6”, “4”, and “8” are stored in the memory. The control unit 21 stores an encryption key used for encryption of the key string in the memory. The control unit 21 outputs the encrypted data of the key string encrypted in s36 to the control unit 2 connected to the input / output I / F 23 (s35), and returns to s31.

As described above, when the PIN pad 9 is in the encryption mode, the data output from the PIN pad 9 to the control unit 2 is encrypted data.
Therefore, when the user is required to input an authentication code that requires security against leakage through the PIN pad 9, the PIN pad 9 is operated in the encryption mode to improve security against the leakage of the authentication code. Can be planned. Even if a malicious third party pulls out the authentication code from the signal transmission line connecting the PIN pad 9 and the control unit 2, the extracted authentication code is encrypted, so this authentication code leaks. Can be prevented.

In addition, when the user inputs ticket information that does not particularly require security against leakage through the PIN pad 9, the PIN pad 9 is operated in the plaintext mode, so that encryption processing and decryption processing are unnecessary. It is possible to suppress an increase in processing load on the ticket vending machine 1 main body. The encryption process is performed by the PIN pad 9, and the decryption process is performed by the control unit 2 as necessary.

Note that the PIN pad 9 may be operated in the encryption mode not only when the authentication code in the above example is input but also when information that requires security against leakage is input. Further, the PIN pad 9 may be operated in the plain text mode not only when inputting the ticket information in the above example but also when inputting information that does not particularly require security against leakage.
Next, a ticket vending machine 1 according to another example will be described. The ticket vending machine 1 according to this example is different in that the ticket issuing process shown in FIG. 7 is performed instead of the ticket issuing process shown in FIG. This ticket vending machine 1 also performs the processes of s1 to s6 described above, and when the card processing unit 8 receives a credit card in s6, it determines whether or not the credit card received this time is within the expiration date (s15). If the control unit 2 determines that it is within the expiration date, it executes the processing of s7 to s9 described in the above example. On the other hand, if the control unit 2 determines that the expiration date is not within s15, the card processing unit 8 releases the credit card accepted this time to the card insertion / release port 8a (s16), and returns to s1.

Thus, the ticket vending machine 1 in this example does not allow the user to input the authentication code when accepting a credit card that is not within the expiration date. This not only prevents the user from inputting the authentication code in vain, but also prevents the authentication code encrypted by the PIN pad 9 from being output to the control unit 2 in vain.
