DETAILED DESCRIPTION OF THE INVENTION
Exemplary embodiments of an electronic image display device, an electronic image display method, and a program for causing a computer to execute the method according to the present invention will be described below in detail with reference to the accompanying drawings.
[0021]
FIG. 1 is an explanatory diagram showing an outline of an electronic payment system including an electronic image display device according to an embodiment of the present invention. As shown in the figure, the main parties involved in this system are a card company 100 that issues a credit card, a card member 101 that is a customer of the company, and a member store 102 that can use the credit card of the company. is there. In addition to the above, there are communication companies that connect the parties through a network, but they are not shown in the figure.
[0022]
On the homepage established by the card company 100 on the Internet, various information for both members and non-members, such as various card lineups and Q & As, as well as IDs and passwords issued only to members (different from credit card numbers and PINs) ), A dedicated tool for requesting and displaying a two-dimensional barcode, which will be described later, can be obtained. This dedicated tool is described in Java (R) or the like, and is incorporated in a mobile phone possessed by the card member 101.
[0023]
When, for example, “2. Apply for barcode” is selected from the menu shown in FIG. 2 displayed on the mobile phone by the above tool, the authentication screen as shown in FIG. 3 is followed by FIGS. Is displayed, the card member 101 inputs and transmits necessary items such as a desired barcode type (effective amount), a valid period, a target product / service, and a store (see FIG. 1). 1 ▼).
[0024]
Here, the bar code has a plurality of types according to the effective amount, such as “for 1 yen to 99 yen (for fractions less than 100 yen)” and “for 1 yen to 999 yen (for fractions less than 1000 yen)”. Yes, the card member 101 can select any desired one. Each bar code has a valid period, and after the valid period, it is automatically deleted from the mobile phone by the tool as described later.
[0025]
The server of the card company 100 that accepts the application from the card member 101 generates and returns a two-dimensional barcode as shown in FIG. 7 (FIG. 1, (2)). The two-dimensional bar code shown in FIG. 4 includes the credit card number of the card member 101 specified from the ID and password entered on the authentication screen of FIG. 3, the validity period of the card, and the bar code selection of FIG. The bar code usage conditions entered on the screen are folded.
[0026]
The card member 101 who has obtained the two-dimensional barcode from the card company 100 as described above selects “1. Display barcode” from the menu of FIG. 2, and the barcode is displayed on the mobile phone display as shown in FIG. Is displayed and read by the bar code reader of the member store 102 ((3) in FIG. 1). For example, when the bar code “for 1 to 999 yen” is presented and the charge is 1367 yen, only 1000 yen is paid in cash.
[0027]
On the other hand, the remaining 367 yen (a fraction less than 1000 yen) is automatically handled as credit, and is charged to the card company 100 from the member store 102 via CAFIS (R) (Credit And Finance Information System) or the like (FIG. 1 (4)). The card company 100 sends a usage statement to the card member 101, deducts the fraction from the account designated by the member on the designated date, and transfers the amount charged to the account designated by the member store 102 ((5) in FIG. 1).
[0028]
Next, FIG. 8 is an explanatory view functionally showing the configuration of the electronic settlement system including the electronic image display device according to the embodiment of the present invention. First, 800a is a member DB (database), which stores personal information of each card member 101, such as its name, address, telephone number, credit card number, credit card validity period, personal identification number, ID and password described above. It is a database to keep.
[0029]
Reference numeral 800b denotes a member authentication unit, which is a function unit that determines whether or not the applicant for issuing the barcode has the authority based on the ID and password transmitted from the authentication screen of FIG. Since the ID and password are encrypted by the above-described dedicated tool, the member authentication unit 800b decrypts the received data and compares it with the member DB 800a to determine whether the ID and password belong to the member of the company. Check whether the member's card is still valid.
[0030]
In the case of authentication OK, that is, when it is determined that the application is from a card member 101 having a legitimate authority, the fact is notified to a barcode designation receiving unit 800c described later, and the credit card of the member read from the member DB 800a is sent. The number, the validity period of the card and the password are output to a barcode generation unit 800d described later.
[0031]
Reference numeral 800c denotes a bar code designation accepting unit. When there is an authentication OK notification from the member authentication unit 800b, a bar code selection screen as shown in FIGS. It is a function part which receives the content input by. Then, the barcode usage conditions received from the mobile phone are output to a barcode generation unit 800d described later.
[0032]
Reference numeral 800d denotes a barcode generation unit that generates a two-dimensional barcode that includes the credit card number and validity period input from the member authentication unit 800b and the barcode usage conditions input from the barcode designation receiving unit 800c. Part. Further, the barcode generation unit 800d includes an explanatory note generation unit 800d-1 and a display key generation unit 800d-2, and a series of data as shown in FIG. 9 is finally generated by these functional units. The
[0033]
In the image area 900 in the figure, barcode image data generated by the barcode generation unit 800d is stored. In the explanatory text area 901, the explanatory text generation unit 800d-1 inserts the explanatory text data of the barcode. This description data specifically describes the usage conditions of the barcode (effective amount, effective period, usable products / services, stores, etc.), notes for the card member 101 and the member store 102, etc. in text. It is.
[0034]
The display key area 902 stores display key data generated by the display key generation unit 800d-2. As will be described later, this display key is data that is collated with the display key on the mobile phone side (the above-mentioned dedicated tool side) prior to displaying the barcode, and more specifically, input from the barcode designation receiving unit 800c. The obtained password is encrypted by a predetermined calculation formula.
[0035]
Returning to FIG. 8, next, 800e is a barcode transmission unit, and the data shown in FIG. 9 created by the barcode generation unit 800d is encrypted by a predetermined algorithm and transmitted to the mobile phone of the card member 101. It is a functional part.
[0036]
Here, it is assumed that a two-dimensional barcode as shown in FIG. 7 is issued, but a so-called barcode (one-dimensional barcode) having a vertical stripe pattern may be used. In this case, since the image can be reproduced by sending only the width and number of individual lines, the amount of communication can be reduced as compared with the case of sending a two-dimensional barcode. In addition, the image is not necessarily limited to a one-dimensional or two-dimensional barcode, and any image (pattern) in which necessary items are folded is sufficient.
[0037]
Here, the valid period of the barcode can be arbitrarily specified at the time of application. For example, the start date may be set to the current date and time, and the end date may be set to the current date + N days, or the value of N may be set to the barcode. It may be changed depending on the type of member or member type (gold / student, etc.).
[0038]
800f is a settlement section that aggregates the charges received from individual member stores 102 via CAFIS (R) and the like for each card member 101 and each member store 102, and withdraws from the account of each card member 101 And a functional unit that instructs a financial institution to deposit money into the account of each member store 102. Since the process in the settlement unit 800f is the same as that in the case where a credit card is presented instead of the two-dimensional barcode, detailed description thereof is omitted.
[0039]
Reference numeral 800g denotes a point updating unit. When the settlement unit 800f confirms that the debit from the account of the card member 101 is completed, the number of points held by the card member 101 is calculated based on the debit amount, that is, the current use amount. This is a functional unit that instructs a point DB 800h, which will be described later, to update the number of points held there with the number of points.
[0040]
Reference numeral 800h denotes a point DB, which is a database that holds the credit card number of each card member 101 and the current number of points held by the member in association with each other.
[0041]
The functional units 800a to 800h described above are realized by a plurality of servers installed by the card company 100. Which function unit is assigned to which server is arbitrary. For example, the functions of the member DB 800a and the member authentication unit 800b are the server A, the functions of the barcode designation receiving unit 800c, the barcode generation unit 800d, and the barcode transmission unit 800e are the server. B. It is conceivable that the settlement unit 800f has the functions of the server C, the point update unit 800g, and the point DB 800h in the server D, and these servers are connected by a LAN. Of course, as long as each functional unit is electronically connected, it goes without saying that it is irrelevant to the essence of the present invention regardless of the physical arrangement.
[0042]
Next, a member authentication unit 801a displays an authentication screen as shown in FIG. 3, and transmits the ID and password input on the screen to the member authentication unit 800b on the card company 100 side for authentication. It is a functional unit that receives notification of OK or authentication NG. In the case of authentication OK, the fact is notified to a barcode designation unit 801b described later, and in the case of authentication NG, an error message to that effect is displayed on the screen.
[0043]
Reference numeral 801b denotes a barcode designation unit which receives the barcode selection screen shown in FIGS. 4 to 6 from the barcode designation reception unit 800c on the card company 100 side, and an effective amount corresponding to the type selected on the screen. This is a functional unit that similarly returns the selected effective period, the usage conditions such as the selected product / service and store to the barcode designation receiving unit 800c.
[0044]
Prior to the reply, a check is made to see if the desired bar code does not overlap with the bar code on hand. You may want to display a confirmation message such as “Do you really want to apply?”.
[0045]
A barcode receiving unit 801c is a functional unit that receives the data of FIG. 9 transmitted from the barcode transmitting unit 800e on the card company 100 side. The received data is decoded by the barcode receiving unit 801c and output to a barcode DB 801d described later.
[0046]
Reference numeral 801d denotes a barcode DB, which is a functional unit that holds data input from the barcode receiving unit 801c and performs reading, deletion of a barcode that has expired, and the like. When the barcode DB 801d accepts a new barcode, it assigns a unique number such as “001” to the barcode.
[0047]
A bar code display unit 801e displays a list of bar codes stored in the bar code DB 801d, and instructs the bar code DB 801d to read out the data of the bar code selected from the list. It is a functional part displayed on the display.
[0048]
When “1. Display barcode” is selected from the menu shown in FIG. 2, the barcode display unit 801e first displays a display option screen as shown in FIG. 10, and displays the barcode in the barcode DB 801d. Let them select from which point of view to narrow down. In the figure, for example, when “1. Product name / alphabetical order” is selected, the line name of the Japanese syllabary is displayed as shown in FIG. Is displayed as shown in FIG.
[0049]
When a product is selected from the list, the barcode DB 801d is instructed to search for a barcode that includes the product in the usable product. Next, the display availability determination unit 801f, which will be described later, is inquired about the display availability of each barcode returned from the barcode DB 801d, and in the case of display OK, the barcode image and description are displayed as shown in FIG. To do.
[0050]
In the figure, the image of the area 1300 is stored in the image area 900 of FIG. 9, and the explanatory text of the area 1301 is also stored in the explanatory text area 901. Further, by pressing an enlarged display button 1302 in the figure, only a barcode image can be displayed as shown in FIG.
[0051]
Returning to FIG. 8, next, reference numeral 801 f denotes a display permission / non-permission determination unit, which responds to the inquiry from the barcode display unit 801 e by answering whether or not the bar code and the description can be displayed, and a display key serving as a basis for the determination of display permission / inhibition This is a functional unit that causes the cardholder 101 to set (display key on the application side that displays the barcode).
[0052]
When “3. Display key setting” is selected from the menu shown in FIG. 2, the display permission determination unit 801 f displays a display key setting screen as shown in FIG. 14. Then, the personal identification number input from the screen is obtained by a predetermined calculation formula (the same calculation formula used when the display key generation unit 800d-2 on the card company 100 side generates display keys for individual barcodes). After encryption, it is stored in the display key storage unit 801f-1.
[0053]
Here, the display key on the application side is set by the individual cardholder 101 after downloading from the server of the card company 100. However, at the time of downloading, it is transmitted after incorporating the encryption code encrypted on the server side. (As described above, since an ID and a password are input at the time of download, the personal identification number can be specified by these pieces of information). However, in this case, if the password is changed, the tool must be downloaded again.
[0054]
The display permission determination unit 801f presents a barcode display key from the barcode display unit 801e, and when there is a display permission inquiry, the display key matches the display key in the display key storage unit 801f-1. Whether or not to match is displayed, a display OK is returned if they match, and a display NG notification is returned to the barcode display unit 801e if they do not match.
[0055]
Note that the functional units 801a to 801f described above are realized by the above-described dedicated tool operating on the mobile phone possessed by the card member 101. This mobile phone corresponds to the electronic image display device according to the present invention.
[0056]

[0058]
Reference numeral 1506 denotes a microphone that converts input sound into an electric signal, 1507 denotes a speaker that converts the input electric signal into sound, and 1508 denotes a communication control unit that controls transmission / reception of radio waves with the radio base station. Reference numeral 1500 denotes a bus connecting the above-described units.
[0059]
Returning to FIG. 8, 802a is a barcode reading unit, which is a functional unit that optically reads the barcode displayed by the barcode display unit 801e of the mobile phone. The read barcode data is output to a barcode analysis unit 802b described later.
[0060]
Reference numeral 802b denotes a barcode analysis unit, which is a functional unit that extracts the credit card number and validity period inserted therein and the barcode usage conditions from the barcode data read by the barcode reading unit 802a. . Each piece of extracted information is output to a usability determination unit 802c described later.
[0061]
Reference numeral 802c denotes an availability determination unit, which is a functional unit that determines whether or not the presented barcode is usable based on information input from the barcode analysis unit 802b. Specifically, the barcode cannot be used if the validity period of the barcode has expired or the validity period of the credit card itself has expired, or if the conditions for usable products or stores are not satisfied. And an error message to that effect is displayed on the register display. In cases other than the above, it is determined that the card can be used, and the credit card number input from the barcode analysis unit 802b and the effective amount of the barcode are output to the sales accounting unit 802d described later.
[0062]
Reference numeral 802d denotes a sales recording unit, which refers to the effective amount of the barcode input from the usability determination unit 802c, and calculates how much the sales amount will be cash sales and credit sales. It is a functional part to do. For example, if the charge is 1367 yen and the presented barcode is "1 to 99 yen", the cash sales is 1300 yen and the credit sales is 67 yen, and the presented barcode is "1 to 999 yen. ", Cash sales are 1000 yen and credit sales are 367 yen.
[0063]
The credit sales recorded by the sales recording unit 802d are the ID of the member store 102, the credit card number of the card member 101, the product / service name, the sales date and time, and the bar code, not the credit card. The sales notification unit 802e transmits the information to the settlement unit 800f of the card company 100 via CAFIS (R). When the member store 102 is one of many branches, the headquarters may first count the bills for each branch and then charge the card company 100 (shown in a simplified manner in FIG. 1). ing).
[0064]
The functional units 802a to 802e described above are realized by a register installed in the member store 102, a barcode reader connected to the register, a CAT terminal, and the like.
[0065]
Next, FIG. 16 is a flowchart showing a procedure of electronic image display processing (specifically, display processing of a two-dimensional barcode) in the electronic image display device according to the embodiment of the present invention. When the card member 101 selects “3. Display key setting” from the menu as shown in FIG. 2 (step S1601: Yes), the display availability determination unit 801f displays a display key setting screen as shown in FIG.

[0067]
Thereafter, when the card member 101 selects “1. Display barcode” from the menu of FIG. 2 (step S1606: Yes), the barcode display unit 801e displays the barcode on a series of screens as shown in FIGS. The narrowing down is guided (step S1607), and the finally narrowed bar code display key is output to the display permission / inhibition determining unit 801f.
[0068]
The display propriety determination unit 801f checks the display key input from the barcode display unit 801e with the display key in the display key storage unit 801f-1, and if they match (Yes in step S1608), the display is OK. (Step S1608: No) The display NG notification is returned to the barcode display unit 801e (Steps S1609 and S1610).
[0069]
Then, in the case of OK, the barcode display unit 801e displays the selected barcode and its explanatory text as shown in FIG. 13 (step S1611), and in the case of NG, “The barcode is displayed because the passwords do not match. An error message such as “cannot be performed” is displayed (step S1612).
[0070]
According to the embodiment described above, unless the display key on the barcode side matches the display key on the mobile phone side (application side for displaying the barcode), the barcode image and the description thereof are not displayed. Even if an unauthorized person obtains a bar code in some way, it cannot be read out by another mobile phone without knowing the password of the card. As a result, even if the bar code is stolen or the bar code is mis-sent, the user's own bar code cannot be used without permission.
[0071]
Also, even if the number of barcodes increases so that it is impossible to grasp when and where the barcodes that can be used are received, according to the present invention, it is possible to narrow down from an arbitrary point of view such as the target product name and store name. You can efficiently retrieve what you need in the scene you want without losing code. In addition, since each bar code is provided with a detailed explanation, even if there are various bar codes, there is no mistake in use.
[0072]
In the above-described embodiment, the barcode for fractional settlement has been described as an example. However, for other purposes, for example, a barcode that functions as a discount coupon (coupon) of a product, a barcode that functions as a membership card, and the like. Even if it exists, the display by the unauthorized person can be prevented by not displaying unless the display keys match. That is, the present invention can be applied to display of any electronic image that is desired to be prevented from being used by unauthorized persons.
[0073]
