In general, a user authentication procedure according to various authentication apparatuses must be preceded in order to use an automatic teller machine (ATM). The user authentication procedure goes beyond simple authentication procedures such as password input, and in recent years, a technology for identifying an individual by using a specific part of the body or behavioral characteristics different from person to person has been developed and used. That is, a bio matrix technology has been developed that performs user authentication with physical characteristics such as fingerprint, palm, iris, retina, and vein.

The automatic teller machine is provided with a user authentication device provided with the biomatrix technology. Thus, the user can prevent illegal financial transactions and the like by using a user authentication device such as the bio matrix.

However, the user authentication apparatus is provided in a different control process for each development / manufacturing company. In other words, the user authentication device is a library including a driver, various routines for executing a control process, and the like, and application programs driven by the routines are developed and provided for each device by different development tools.

Therefore, the user authentication process is performed by a driver / library / application program provided differently while a plurality of devices are mounted in the automated teller machine.

Here, if a new device is added to the automated teller machine, a library for controlling the device should be provided, and a problem arises in that an application program driven by the library should be modified. In addition, there is an inconvenience in repairing / maintaining the automated teller machine, and a problem of inferior recyclability has occurred.

According to a feature of the present invention for achieving the above object, the present invention comprises a driver for driving a plurality of devices each having a different control scheme; A storage unit which stores a library written for each device according to a standard interface class provided with a plurality of standardized execution routines; A library selector which searches the storage and selects a library corresponding to the driven device; And an application program for executing the library selected by the library selection unit to control the corresponding device.

It is preferable to further include a development tool for creating the library.

Preferably, the standard interface class is provided with a plurality of execution routines executed by an application program.

Preferably, the execution routine is information necessary for driving the device.

The library is preferably allocated and stored for each predetermined address.

According to another aspect of the invention, the invention comprises the steps of creating a library for each device by a standard interface class provided with a number of standardized execution routines; Storing the created library; If any device is driven, searching / selecting a corresponding library; And performing a corresponding function according to the selected library.

The library is preferably created by a development tool different for each device.

The created library is preferably allocated and stored for each predetermined address.

Preferably, the library is provided with a plurality of execution routines independently.

It is preferable that some of the execution routines can be provided in common to two or more libraries.

The execution routine is preferably provided differently depending on the type of device.

According to the present invention having such a configuration, by providing a standard interface to devices having different control methods, the ATM device developer has an advantage of controlling a plurality of devices through the same application program.

Hereinafter, a device interface method and a device according to the present invention having the configuration as described above will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration diagram of a device interface device according to an exemplary embodiment of the present invention.

The present invention will be described with reference to an embodiment in which the automated teller machine and one or more devices that recognize a fingerprint and perform user authentication.

According to this, first to third devices 10a to 10c are provided which recognize fingerprints and perform user authentication by different control schemes. The first to third devices 10a to 10c are equipped with a fingerprint sensing unit (not shown) for detecting a fingerprint.

In one financial teller 100 connected to the first to third devices 10a to 10c, first to third drivers 20a to 20c for driving the first to third devices 10a to 10c are provided. Are respectively provided correspondingly.

In addition, the standard interface class 40 is provided to standardize different control methods of the first to third devices 10a to 10c. The standard interface class 40 is provided with a number of standardized execution routines such that the first to third devices 10a to 10c can be controlled by standardized control schemes. The execution routine is independently provided with a routine for the first to third devices 10a to 10c to detect a fingerprint and process user authentication.

Here, the execution routine may be provided as shown in [Table 1]. The process of performing user authentication by the execution routine shown in Table 1 will be described later.

[Table 1]

One Load library for sensor drive 2 Reset sensor 3 Image scanning 4 Sensor Close 5 Unload Library for Sensor Drive 6 Sensor Preferences 7 Sensor information acquisition 8 Image correction 9 Error handling

In [Table 1], execution routines such as 'sensor drive library load', 'sensor initialization', 'error processing' and the like are provided, but [Table 1] is merely an embodiment, and It is preferred that each library 50a to 50c be provided with a variety of execution routines, without being limited thereto.

And a library for the first to third devices 10a to 10c so that the first to third devices 10a to 10c can be operated by an application program 70 to be described later based on the execution routine. 50a to 50c are created with reference to the respective development tools 30a to 30c.

The development tools 30a to 30c are provided differently from the manufacturers who manufacture the first to third devices 10a to 10c, respectively, and the first to third devices created by the development tools 30a to 30c. The libraries 50a to 50c of 10a to 10c are allocated for each device and stored in the memory 50 according to predetermined address information. That is, execution routine information is stored for each device in the libraries 50a to 50c stored in the memory 50. Here, the execution routine common to each device may be stored in the same address information, or may be stored in address information allocated to each device.

The memory 50 is searched and the library 50a to 50c assigned to the predetermined address information of the memory 50 by driving any one of the first to third devices 10a to 10c are pointed at the application. A library selection unit 60 for providing the program 70 is provided.

The application program 70 executes a corresponding execution routine by the libraries 50a to 50c pointed to by the library selection unit 60 to perform a user authentication process.

Next, a device interface method and apparatus according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

2 is a flowchart illustrating a device interface method according to an exemplary embodiment of the present invention.

A case where the first to third devices 10a to 10c are provided in one financial teller machine 100 will be described.

Accordingly, a company providing the first to third devices 10a to 10c is provided with a standard interface class 40 provided by the operator of the automated teller machine 100, and is developed differently for each terminal device company. Each of the libraries 50a to 50c for the first to third devices 10a to 10c is created using the tools 30a to 30c (steps 200 and 202).

Each of the created libraries 50a to 50c is allocated to each device and stored in the memory 50 according to predetermined address information (step 204).

After that, it will be described that the device is driven according to a user's request. In this case, the first to third devices 10a to 10c operate the corresponding device according to the control method of the same application program 70. Thus, the first device 10a of the first to third devices 10a to 10c will be described as an embodiment. However, in the present invention, the present invention is not limited to the first device 10a but may be provided as a plurality of devices including the second and third devices 10b and 10c.

According to this, the first device 10a is operated according to the user's request (steps 206 and 208).

Then, the library selector 60 searches for address information of the memory 50, selects the first library 50a corresponding to the first device 10a, and transmits it to the application program 70 (operation 210). Step 212).

Accordingly, the application program 70 performs user authentication according to the execution routine provided by the first library 50a (step 214).

Specifically, the execution routine of the first library 50a of the first device 10a by the development tool 30a is as shown in Table 1, such as '1-2-8-3-4-5'. In the case of writing in the order, the application program 70 executes the 'fingerprint sensing unit loading' execution routine provided in the first library 50a to load the fingerprint sensing unit and executes the 'sensor initialization' execution routine to initialize the sensor. Let's do it. The scanned image is executed by executing an 'image correction' execution routine, and the 'fingerprint extraction algorithm' execution routine is executed to extract the scanned fingerprint. Accordingly, the application program 70 stops the sensor driving by realizing the 'Sensor Close' execution routine, and unloads the fingerprint sensing unit by executing the 'Unload fingerprint sensing unit' execution routine. In addition to this, the first library 50a has a 'sensor configuration'. An execution routine such as 'error processing' may be provided to set an initial environment of the sensor, and may process an error generated when the fingerprint data is scanned.

However, this is only one embodiment. That is, the order in which the execution routines are executed may be provided differently, and the configuration of the execution routines provided in the library may be provided differently for each device. However, it is preferable that an execution routine necessary for performing fingerprint recognition, such as a routine provided for each device, for example, 'fingerprint sensing unit load' image scan, etc., is commonly provided. For example, when the execution routine of the second library 50b is in the order of '1-2-3-4-5-6-7-8', when the second device 10b is driven, the second library 50b ) Is transmitted to the application program (70). Then, the application program 70 performs user authentication in the above-described order.

In addition, if the execution routines of the libraries 50b and 50c of the second device 10b and the third device 10c are the same, for example, up to the term '1-4' in [Table 1] and the remaining execution routines are different, Up to '1-4' are selected and executed in the same routine, and the rest are performed by each library.

On the other hand, when a new device is added to the automated teller machine 100, it receives a standard interface class 40, creates a library for its own device, and provides it to the teller machine 100. Thus, the library is stored in the memory 50 by predetermined address information allocated to a new device.

In the future, when the device is selected according to the user's selection, the application program 70 receives an execution routine included in the library of the device to perform user authentication.

According to the present invention having such a configuration, by providing the standard interface class 40 to the first to third devices 10a to 10c having different control methods, the ATM 100 developer can use the same application program 70. ) Can control multiple devices.

As described above, it has been described with reference to the illustrated embodiment of the present invention, which is merely exemplary, and those skilled in the art to which the present invention pertains various modifications without departing from the spirit and scope of the present invention. It will be apparent that other variations and equivalent embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

As described above, the device interface method and apparatus may expect the following effects.

First, the present invention provides a standard interface class to one or more devices having different control methods, and thus, there is an advantage in that a plurality of devices can be controlled by applying the same application program to one ATM.

In addition, the present invention has the advantage that the maintenance and repair of the device is increased and the recyclability is increased by using the same application program for adding a new device or modifying an existing device.
