Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the figure, the same or corresponding parts are designated by the same reference numerals and the description is not repeated.

First, the configuration of the information processing apparatus 10 according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a diagram showing an example of a device provided with an information processing apparatus 10 according to an embodiment of the present invention. The information processing device 10 is provided in, for example, an automated teller machine (ATM) 1. The information processing device 10 includes a processor such as a CPU (Central Processing Unit). ATM1 is an example of a password determination device.

The ATM 1 includes a card reading unit 11 and a display unit 12. The card reading unit 11 reads information such as a cash card inserted by the user. Generally, when the card reading unit 11 reads information such as a cash card, the processor of the ATM 1 performs a user authentication process. For example, when the authentication process is started, the processor of the ATM 1 displays the authentication process screen on the display unit 12. The display unit 12 is, for example, a display provided with a touch panel.

The processor of ATM1 displays, for example, a numeric keypad and a password input field on the authentication processing screen. In the present embodiment, the password is, for example, a four-digit password that is a combination of four numbers.

The user operates the numeric keypad and enters the password. If the password entered by the user is correct, the processor of ATM1 determines that the authentication is successful.

Here, at ATMs, many users may be waiting for their turn. If the user can enter the password while waiting for his turn, the waiting time can be shortened.

In the present embodiment, the card reading unit 11 includes, for example, a thermography camera. The card reading unit 11 reads the surface temperature of a cash card or the like inserted by the user, and generates a temperature distribution image showing the temperature distribution of the read surface temperature. The card reading unit 11 is an example of a temperature distribution image generation unit.

In the present embodiment, the information processing apparatus 10 performs the authentication process using the temperature distribution image generated by the card reading unit 11.

Next, the temperature distribution image will be described with reference to FIGS. 2 and 3. FIG. 2 is a diagram showing an example of a card CC read by the card reading unit 11. FIG. 3 is a diagram showing an example of a temperature distribution image generated by the card reading unit 11.

For example, the number "0" to "9" corresponding to each digit of the password is drawn on the card CC read by the card reading unit 11. The user can select a 4-digit password by selecting and pressing each digit of the password. The card CC is, for example, a cash card on which a number as shown in FIG. 2 is drawn on the back surface.

The card CC may be a card different from the cash card. The shape, size and material of the card CC are not particularly limited.

The password is not limited to 4 digits, but may be 3 digits or less or 5 digits or more. Further, the password is not limited to numbers, but may be characters including symbols and patterns.

Specifically, in the card CC, the temperature of the part pressed by the user rises. As shown in FIG. 2, the user presses "1" for the 4th digit of the password, "1" for the 3rd digit, "2" for the 2nd digit, and "3" for the 1st digit. And the password "1123" is selected.

As described above, when the card reading unit 11 reads the card CC for which the password "1123" is selected, the card reading unit 11 generates the temperature distribution image shown in FIG. In the present embodiment, the user does not see the temperature distribution image because the temperature distribution image is displayed on the display unit 12, but the user does not see the temperature distribution image.

In FIG. 3, for the sake of simplicity, the card CC is divided into 14 in the longitudinal direction (A to P), 10 in the lateral direction (1 to 10), and A to P and 1 to 10 are combined. Represents the position on the card CC. Further, although FIG. 3 is shown by superimposing FIG. 2 for the sake of simplicity of explanation, the temperature distribution image does not include the symbol drawn in FIG. 2.

In the temperature distribution image, the high temperature part indicating above the predetermined temperature is displayed in red, and the low temperature part indicating below the predetermined temperature is displayed in blue. In the example of FIG. 3, the positions D4, D5, E6, and F7 are displayed in red, and the other portions are displayed in blue. In FIG. 3, the portion displayed in red is shown by hatching.

As shown in FIG. 1, the card reading unit 11 transmits the temperature distribution image data showing the generated temperature distribution image to the information processing apparatus 10.

Next, the information processing apparatus 10 will be described with reference to FIG. FIG. 4 is a functional block diagram of the information processing apparatus 10 according to the embodiment of the present invention.

The information processing device 10 includes a storage unit 102 and a control unit 100. The storage unit 102 stores the password information indicating the password in advance. The storage unit 102 includes a semiconductor memory such as a RAM (Random Access Memory) and a ROM (Read Only Memory). The control unit 100 includes a processor. The processor is, for example, a CPU, an MPU (Micro Processing Unit), an ASIC (Application Specific Integrated Circuit), or the like.

The control unit 100 functions as an acquisition unit 101, a generation unit 103, and a determination unit 104 when the control program stored in the ROM or the storage unit 102 is executed by the processor. The acquisition unit 101, the generation unit 103, and the determination unit 104 may be configured by a logic circuit regardless of the operation based on the control program. The acquisition unit 101 receives the temperature distribution image data, and acquires the temperature distribution information indicating the correspondence relationship between the high temperature portion and the position of the high temperature portion from the temperature distribution image data.

The generation unit 103 generates input password information based on the temperature distribution information acquired by the acquisition unit 101. The determination unit 104 executes a password determination process for determining whether or not the input password information generated by the generation unit 103 matches the password information.

Specifically, the acquisition unit 101 receives the temperature distribution image data from the card reading unit 11 and acquires the temperature distribution information from the temperature distribution image indicated by the temperature distribution image data.

For example, when the acquisition unit 101 receives the temperature distribution image data showing the temperature distribution image of FIG. 3, it acquires the temperature distribution information indicating that the positions D4, D5, E6, and F7 are high temperature portions.

The generation unit 103 generates input password information indicating an array of input characters based on the temperature distribution information acquired by the acquisition unit 101.

Specifically, the generation unit 103 refers to the character correspondence information stored in the storage unit 102, and the character corresponding to each of the plurality of high temperature portions (positions D4, D5, E6, F7) indicated by the temperature distribution information. ("1", "1", "2", "3") is specified. The character correspondence information indicates the correspondence relationship between the position indicated by the temperature distribution information and the character drawn on the card CC.

The generation unit 103 also determines the arrangement of the characters "1", "1", "2", and "3" corresponding to each position based on the positions D4, D5, E6, and F7 indicated by the temperature distribution information. .. In this way, the generation unit 103 generates the input password information "1123".

The determination unit 104 determines whether or not the input password information "1123" generated by the generation unit 103 matches the password information stored in the storage unit 102, and determines whether the authentication is successful or unsuccessful.

For example, if the input password information matches the password information, the determination unit 104 determines that the authentication is successful, and if the input password information does not match the password information, determines that the authentication fails.

In the present embodiment, when the determination unit 104 determines that the authentication is successful, the card reading unit 11 reads the information of the card CC. On the other hand, if the determination unit 104 determines that the authentication has failed, the card reading unit 11 does not read the information on the card CC. If the input password information does not match the password information, the determination unit 104 may perform a process of displaying the authentication processing screen for requesting the user to input the password by the numeric keypad on the display unit 12, for example.

In this way, if the temperature distribution image is used for the authentication process, the user can shorten the waiting time by touching the card CC in advance. Further, since the card CC can be shared with a function such as a cash card, a new card CC is not required and the burden on the user does not increase.

In the present embodiment, the password is not limited to an array of a plurality of characters, but may be an array of a plurality of positions in the temperature distribution image.

In this case, the generation unit 103 determines the arrangement of the positions D4, D5, E6, and F7 based on the plurality of high temperature portions (positions D4, D5, E6, F7) indicated by the temperature distribution information, and generates the input password information. do.

Next, the authentication process according to the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing the authentication process according to the present embodiment.

When the surface temperature of the card CC inserted by the user is read by the card reading unit 11, the acquisition unit 101 receives the temperature distribution image data and acquires the temperature distribution information from the temperature distribution image data (step S11).

The generation unit 103 generates input password information based on the temperature distribution information acquired by the acquisition unit 101 (step S12).

The determination unit 104 executes a password determination process for determining whether or not the input password information generated by the generation unit 103 matches the password information (step S13).

When the determination unit 104 determines that the input password information generated by the generation unit 103 matches the password information (YES in step S13), it determines that the authentication is successful (step S14).

On the other hand, when the determination unit 104 determines that the input password information generated by the generation unit 103 does not match the password information (NO in step S13), it determines that the authentication has failed (step S15), and inputs another password. Obtain (step S11).

In the present embodiment, the card reading unit 11 is configured to include a thermography camera, but the present invention is not limited to this, and a thermography camera may be provided in the ATM 1 separately from the card reading unit 11. In this case, the acquisition unit 101 receives the temperature distribution image data generated and transmitted by the thermography camera.

Further, in the present embodiment, the storage unit 102 is configured to be provided inside the information processing device 10, but the storage unit 102 may be provided outside the information processing device 10. In this case, for example, the storage unit 102 may include a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive).

Further, in the present embodiment, the card CC has a structure in which characters and the like are drawn, but the present invention is not limited to this, and nothing may be drawn. For example, when the user visually touches a plurality of positions on the card CC corresponding to the password, the acquisition unit 101 can acquire sufficient temperature distribution information for the generation unit 103 to generate the input password information. ..

In the present embodiment, after the temperature distribution image is generated, the card reading unit 11 may continue to hold the card CC until the card CC is cooled and does not have a high temperature portion. For example, the card reading unit 11 periodically generates a temperature distribution image after the card CC is inserted, and continues to hold the card CC without ejecting it until a temperature distribution image having a uniform temperature distribution is generated. ..

This makes it possible to prevent a situation in which the temperature distribution information used in the authentication process before the previous time and the temperature distribution information used in the authentication process to be performed in the future are mixed and the input password information cannot be generated correctly. Further, for example, when the card CC is shared by a plurality of people, it is possible to prevent the temperature distribution information used in the authentication process before the previous time from being known to other users. When the card CC is a card that is not shared, such as a credit card, the card reading unit 11 may eject the card CC without waiting for the card CC to cool down.

Further, in the present embodiment, the information processing device 10 is configured to be provided in the ATM 1, but the information processing device 10 and the ATM 1 may be different devices.

Next, with reference to FIG. 6, the configuration of the information processing apparatus 10 according to another embodiment of the present invention will be described. FIG. 6 is a diagram showing an information processing apparatus 10 according to another embodiment of the present invention.

In the example of FIG. 6, the information processing device 10 is, for example, a server. The ATM 1 and the information processing apparatus 10 can communicate with each other via the network 20. The network 20 may include, for example, at least one of a LAN (Local Area Network) and a wireless LAN. The card reading unit 11 transmits the temperature distribution image data showing the generated temperature distribution image to the information processing apparatus 10 via the network 20.
