Will be.

Hereinafter, a preferred embodiment of a key-map arrangement changing device and a key-map arrangement changing method of an automated device according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram of a device for changing a key-map arrangement in an automated device according to the present invention.

As shown, the key-map arrangement changing apparatus of the present invention is provided inside the automated teller machine, and is provided with a touch pad type touch screen 102 displaying a series of key selection inputs and transaction details to perform a financial business. do. The touch screen 102 is to detect the movement of the finger of the customer and the pressure to press down and input the selected information. In addition, the touch screen 102 initially displays a financial transaction guide screen for selecting a financial service, and when the financial service is selected, a fixed type before-change key-map array for inputting a password or the like (FIG. 4A). )) Is displayed. The touch screen 102 is further provided with a selection key (not shown) that allows a customer to request a change in the key-map arrangement. The selection key is for changing and displaying the fixed-type key-map arrangement according to a customer's request, and may be displayed as a guide message on the financial transaction guide screen.

The modified key-map arrangement is provided according to a customer request for performing a financial service or at least two or more modified key-map arrangements are arranged randomly according to the control logic unit 100. In order to change the key-map arrangement, the key arrangement program unit 104 and the key arrangement program unit 104 correspond to each key value of the key-map under a control of the control logic unit 100. A function providing unit 105 for storing JavaScript and / or flash so as to perform the key-map change should be provided. In addition, since the customer can directly change the key-map arrangement, the key arrangement changing unit 106 is provided, which uses the function providing unit 105 to map each key value of the key-map to a value to be changed. . As described above, after the key array program unit 104 and the key array change unit 106 correspond to the key value to be changed, the control logic unit 100 rearranges the key array program in the key-map form.

In addition, the data storage unit 108 for storing customer-related data such as account number, password, etc. of the customer, and the data storage unit 108 and the information input through the touch screen 102 when the financial transaction occurs from the customer An authentication processing unit 110 for comparing the information stored in the file, and determining the validity thereof is provided. In addition, the transaction history storage unit 112 for storing the transaction details of the control program or the automated teller machine, and the interface unit 114 for exchanging information with the financial server 120 is provided. The financial server 120 serves to store and manage all financial business data made in the automated teller machine.

Next, the key-map arrangement changing method provided in the automated device of the present invention having the configuration as described above will be described in detail.

If the automatic teller machine according to the present invention is powered on, the financial transaction guide screen is displayed on the touch screen 102 under the control of the control logic unit 100 (step 200). The financial transaction guide screens are financial transaction service buttons for selecting a financial business, for example, buttons representing cash withdrawal, deposit, check withdrawal, balance inquiry, credit card business, and the like. The financial automated device on which the financial transaction guide screen is displayed maintains a standby state.

When the customer who wants a financial transaction in the standby state inserts a bankbook or a card and selects a financial transaction (step 202), the control logic unit 100 recognizes this and displays a guide screen for the next guide on the touch screen 102. ). The guide screen is usually a password input screen for user authentication for the customer. The password input screen is a known type as shown in FIG.

In this case, the control logic unit 100 displays a guide message on the touch screen 100 asking whether to change the arrangement of the key-map currently displayed on the touch screen 102 in step 204. That is, when the known key-map array is displayed, a guide message such as 'Do you want to change the current key-map array?' According to the guide message display, the customer selects whether to change the key-map arrangement or to use the currently displayed fixed type key-map arrangement (step 206). If the fixed key-map arrangement is used in step 206, the process proceeds to step 216, where the customer inputs a password or the like on the touch screen 102 and displays on the touch screen 102 in step 218. We will proceed with a series of financial transactions while checking the contents.

However, if it is desired to change the key-map arrangement in the selection process of step 206, when the selection button is operated, the control logic unit 100 proceeds to step 208 to control the key-map arrangement again. On the touch screen 102 to change according to the present invention or to provide a modified key-map arrangement set by the customer. In this case, the control logic unit 100 may be displayed in the form of a series of guide messages.

When the customer requests the changed ten-key arrangement through the control logic in step 208, the control logic unit 100 accesses the key arrangement program unit 104 to randomize the fixed key-map arrangement. To arrange them. Accordingly, as in step 210, the key arrangement program unit 104 calls a JavaScript or flash function stored in the function storage unit 105 using a window message, and the control logic unit 100. Based on the arrangement information of the key-map provided from the) to a key value to be changed at random to a key value having a different value.

3 shows an embodiment in which the key-map arrangement is rearranged. Looking at the above embodiment, in the configuration of the conventional basic ten-key arrangement, the numeric key '0' corresponds to '1', '4' corresponds to '5', and '6' corresponds to '7'. Each of the rearranged key-map arrays may be provided under a control of the control logic unit 100.

When each key value of the key-map is completed with a different value as shown in FIG. 3 by the key arrangement program unit 104, the control logic unit 100 analyzes the arrangement configuration of the rearranged key values. The arrangement is changed to a key-map form as shown in (b) of (step 212).

Then, the changed key-map arrangement is displayed on the touch screen 102 by the control logic unit 100 (step 214), and the customer can input a password in a key-map arrangement having a different arrangement from the prior art. It becomes possible. Since the position of each key value is changed in this way, even if the customer enters a password, the third party cannot find out the entered password.

When the password is input and it is confirmed by the authentication processing unit 110 that the customer is a legitimate customer, the customer can continue the desired financial transaction (steps 216 and 218).

On the other hand, as described above, the control logic unit 100 may change the key-map arrangement itself and provide it to the customer, and the customer may directly change and use the key-map arrangement. That is, this is the case when the customer requests a key-map arrangement directly changed from step 208. In this case, the process of directly changing the key-map arrangement by the customer is similar to the operations of the control logic unit 100 and the key arrangement program unit 104 described above. However, there is a difference in that the function of the key arrangement changing unit 106 is performed in that the customer can change it directly, and the customer can change the at least one key-map arrangement in advance by using the same.

In order to change the key-map arrangement, if a request for using the key-map arrangement set by the customer is generated as described above, in step 220, the control logic unit 100 changes the key arrangement change unit 106. ) And call the JavaScript or Flash function. Then, the key arrangement changing unit 106 performs a process of mapping the key values to be changed to key values having different values based on the arrangement information of the key-map provided from the control logic unit 100. (Step 222).

In other words, when each key value of the key-map is completed with a different value as shown in FIG. 3 by the key arrangement changing unit 106 as described above, the control logic unit 100 determines the rearranged key values. The arrangement configuration is analyzed and rearranged in a key-map form as shown in FIG. 4B (step 224).

Here, in step 224, the customer must change the plurality of key-map arrangements before performing the financial transaction, and can be immediately selected and provided during the financial transaction. If the customer describes the process of changing the key-map arrangement as an example.

When the fixed key-map arrangement is displayed on the touch screen 102, a guide message indicating how many times each key is to be changed is displayed. The customer can then change the key content while checking the announcement. For example, when a key-map arrangement screen is displayed and a message for changing the numeric keys to be sequentially changed is displayed, the customer may change the key-map arrangement by setting the desired number key. Of course, the customer may specify in advance a plurality of key-map arrangements desired by the window of the financial institution, and may be provided whenever a financial transaction occurs in the automated teller machine.

When the plurality of key-map arrangements are changed as described above, when the control logic unit 100 displays the plurality of key-map arrangements on the touch screen 102 (step 226), the customer selects one of them. In the selected key-map array, enter the password to perform the financial transaction. Similarly, since the key position is changed, even if the customer enters a password, the third party cannot find out the entered password. When the password is input and it is confirmed by the authentication processing unit 110 that the customer is a legitimate customer, the customer can continue the desired financial transaction (steps 216 and 218).

As described above, according to the present invention, the key-map displayed on the touch screen, that is, the arrangement of the ten-keys can be changed, so that the input information such as the password and the account number of the customer is exposed in the automated teller machine. It can be prevented.

As described above in detail, according to the present invention, the key arrangement displayed on the touch screen of the automatic teller machine can be changed so that a third party guesses the key position when the customer inputs a password or account number by operating a key. There is an effect that can be prevented to find out.

In addition, there is an effect that can be expected to improve the competitiveness of the device by providing a function, such as when the automatic teller machine at the time of the key arrangement change randomly rearranged by itself or by providing a customer by changing the key arrangement directly.
